IN THE NEWS & CALENDAR<br />

What Happened With<br />

Education in the Latest<br />

National Budget?<br />

The following quick summary was<br />

provided in The Washington Post by<br />

writer, Michael A. Fletcher: The<br />

administration is requesting $56<br />

billion for the Education Department,<br />

a cut <strong>of</strong> half a billion dollars, or 0.9<br />

percent, from fiscal 2005—the first<br />

reduction in overall federal education<br />

spending in a decade. The budget<br />

would eliminate the Perkins loan<br />

program, which provides low-interest<br />

loans to low- <strong>and</strong> middle-income<br />

college students. The budget would<br />

use those savings to increase<br />

spending on Pell grants, which<br />

provide college grants to low-income<br />

students, <strong>and</strong> raise the maximum<br />

award $100, to $4,150. In all, 48<br />

education programs would be<br />

terminated, including those providing<br />

college-readiness training to lowincome<br />

high school students <strong>and</strong><br />

federal vocational education<br />

initiatives that the White House said<br />

are not performing well or duplicate<br />

other federal efforts. Some <strong>of</strong> the<br />

savings would be used to increase<br />

spending in several programs,<br />

including $1.5 billion to extend<br />

federal No Child Left Behind testing<br />

<strong>and</strong> accountability requirements into<br />

the nation’s high schools.<br />

ITEA’s current efforts are to continue<br />

to be a part <strong>of</strong> larger coalitions that<br />

are seeking science, technology,<br />

engineering, <strong>and</strong> mathematics<br />

(STEM) funding <strong>and</strong> to support<br />

continued funding for the vocational<br />

community. ITEA will continue to<br />

educate its members <strong>and</strong> other<br />

interested colleagues in procedures<br />

to gain more funding at the state<br />

level. Selected states are having<br />

successes with funding, <strong>and</strong> all are a<br />

result <strong>of</strong> the members being active in<br />

communicating with their elected <strong>and</strong><br />

appointed representatives or <strong>of</strong>ficials.<br />

ITEA’s efforts included a March<br />

Legislative Symposium in conjunction<br />

with the Triangle Coalition for<br />

Science & Technology Education.<br />

Information can be found on ITEA’s<br />

Web site—www.iteawww.org.<br />

ITEA’s 2005 Kansas City Conference<br />

will have programs that address<br />

legislative issues <strong>and</strong> strategies that<br />

have proven success at the state<br />

level.<br />

has shared the following article<br />

regarding trends in higher education:<br />

The Wall Street Journal identifies 10<br />

trends in higher education that bear<br />

watching in coming years. Among<br />

them:<br />

• Tuition will continue to rise, partly<br />

in response to reduced state<br />

funding to public institutions <strong>and</strong><br />

bidding wars among private<br />

institutions for hotshot pr<strong>of</strong>essors.<br />

• Financial aid based on merit will<br />

continue to gain in popularity as<br />

colleges compete for the brightest<br />

students.<br />

• Colleges will look increasingly to<br />

distance learning <strong>and</strong> competency<br />

assessments to ease classroom<br />

crowding.<br />

• As universities seek to<br />

differentiate themselves, they will<br />

mix the liberal arts with science<br />

<strong>and</strong> technology to create new<br />

interdisciplinary studies.<br />

• More colleges will emphasize the<br />

quality <strong>of</strong> their teaching.<br />

<strong>International</strong> Studies<br />

Show Mixed Results<br />

Among U.S. Students<br />

The latest results <strong>of</strong> two major<br />

international studies present a mixed<br />

picture <strong>of</strong> the academic abilities <strong>of</strong><br />

American students. In the 2003<br />

Trends in <strong>International</strong> Mathematics<br />

<strong>and</strong> Science Study (TIMSS),<br />

American fourth- <strong>and</strong> eighth-graders<br />

significantly outperformed many <strong>of</strong><br />

their international peers. While<br />

eighth-graders—including boys, girls<br />

<strong>and</strong> minority students—improved<br />

their scores compared to past TIMSS<br />

studies (1995 <strong>and</strong> 1999), scores for<br />

fourth-graders remained static in both<br />

subject areas.<br />

In the 2003 Program for <strong>International</strong><br />

Student Assessment (PISA), U.S.<br />

ninth- <strong>and</strong> tenth-graders (15-yearolds)<br />

performed below the<br />

international average in math literacy<br />

<strong>and</strong> problem-solving. This lag among<br />

high school students, says President<br />

Bush <strong>and</strong> U.S Secretary <strong>of</strong> Education<br />

Margaret Spellings, underscores the<br />

need for annual learning assessments<br />

for all students in Grades 9-11. Under<br />

the No Child Left Behind Act, such<br />

assessments currently apply only to<br />

students in Grades 3-8.<br />

The PISA results were released in<br />

December 2004 by the Paris-based<br />

Organization for Economic<br />

Cooperation <strong>and</strong> Development. A<br />

report on America’s PISA results,<br />

published by the U.S. Department <strong>of</strong><br />

TEACHING ELEMENTS AND<br />

PRINCIPLES OF BRIDGE DESIGN<br />

FEATURE ARTICLE<br />

Charles Beck<br />

<strong>Bridge</strong> construction is a popular<br />

classroom activity. However, the<br />

basic principles <strong>of</strong> tension,<br />

compression, <strong>and</strong> counterbalance are<br />

not always clearly represented <strong>and</strong><br />

defined. The common materials used<br />

to construct model bridges, such as<br />

straws, toothpicks, Legos, <strong>and</strong><br />

building blocks, are <strong>of</strong>ten too flexible<br />

or stationary to demonstrate the<br />

principles that keep bridges upright<br />

<strong>and</strong> functional. If the basic principles<br />

are not clearly demonstrated,<br />

students will fail to underst<strong>and</strong> how<br />

bridges are able to support heavy<br />

loads. Upper elementary <strong>and</strong> middle<br />

school students can design simple<br />

models that demonstrate the<br />

essential elements <strong>and</strong> basic<br />

principles <strong>of</strong> bridge design.<br />

ITEA St<strong>and</strong>ards<br />

<strong>Design</strong>ing model bridges addresses<br />

several <strong>of</strong> ITEA’s St<strong>and</strong>ards for<br />

Technological Literacy (ITEA,<br />

2000/2002). For example, by<br />

identifying basic elements <strong>and</strong><br />

principles <strong>of</strong> bridge design, students<br />

develop an underst<strong>and</strong>ing <strong>of</strong> the<br />

“attributes <strong>of</strong> design” (St<strong>and</strong>ard 8)<br />

<strong>and</strong> “engineering design” (St<strong>and</strong>ard<br />

9). Students “select <strong>and</strong> use<br />

constructive technologies” (St<strong>and</strong>ard<br />

20) when they design model bridges<br />

<strong>and</strong> test their ability to support loads.<br />

Most states have Instructional<br />

Frameworks or St<strong>and</strong>ards that require<br />

classroom teachers to expose their<br />

students to the basic physical<br />

principles <strong>of</strong> engineering <strong>and</strong><br />

technology. Based on the<br />

By designing model bridges, students can<br />

begin to appreciate how engineers construct<br />

elements that produce tremendous force,<br />

such as arches <strong>and</strong> cables.<br />

Figure 1: Arch <strong>Bridge</strong> Construction <strong>Principles</strong> <strong>and</strong> <strong>Elements</strong><br />

constructivist theory to learning,<br />

students need to design models to<br />

underst<strong>and</strong> these principles.<br />

Materials<br />

The drawings illustrate two common<br />

types <strong>of</strong> bridges—the arch <strong>and</strong> the<br />

suspension. The arch bridge (see<br />

Figure 1) may be constructed from<br />

Styr<strong>of</strong>oam or wooden wedges. Paper<br />

clips or cotter pins are used to secure<br />

the abutments. To prevent the<br />

wedges from wobbling, they should<br />

be about two inches in thickness.<br />

The suspension bridge (see Figure 2)<br />

is constructed from balsa for the<br />

towers, deck, <strong>and</strong> anchorages. The<br />

illustration shows short side decks<br />

<strong>and</strong> cable spans. The students may<br />

want to lengthen the side decks <strong>and</strong><br />

their cable spans to resemble an<br />

actual suspension bridge. The cables<br />

<strong>and</strong> suspenders are made from paper<br />

clips linked together. In order to show<br />

tension, the deck should only be<br />

1/16” to 1/8” in thickness. The tower<br />

framework is about 1/4” in thickness.<br />

The paper clips or pins must pass<br />

through the abutments <strong>and</strong><br />

anchorages <strong>and</strong> into the baseboard.<br />

Students may use glue or paper clips<br />

to secure the tower cross beams to<br />

the uprights <strong>and</strong> the foundations to<br />

the baseboard. It should not be<br />

difficult to push paper clips through<br />

balsa. These materials are available<br />

in most arts <strong>and</strong> crafts supply stores.<br />

FEATURE ARTICLE<br />

Figure 2: Suspension <strong>Bridge</strong> Construction <strong>Principles</strong> <strong>and</strong> <strong>Elements</strong><br />

Students should be encouraged to<br />

experiment <strong>and</strong> problem-solve with<br />

the elements. For example, they<br />

should experience what happens<br />

when loads, such as toy cars or metal<br />

weights, are placed on the bridges,<br />

<strong>and</strong> the paper clips are removed from<br />

the abutments <strong>and</strong> anchorages. They<br />

will observe how the wedges collapse<br />

from the outward compression, <strong>and</strong><br />

how the towers lean <strong>and</strong> the deck<br />

sags from the tension. If the deck is<br />

cut in half, the tension on the cables<br />

<strong>and</strong> towers will become more visible<br />

when a load is placed on the deck.<br />

The suspension bridge illustration<br />

shows how each half <strong>of</strong> the deck is<br />

supported by a pair <strong>of</strong> cables.<br />

<strong>Bridge</strong> <strong>Principles</strong><br />

The arch bridge must counterbalance<br />

a great deal <strong>of</strong> compression, whereas<br />

the suspension bridge must<br />

counterbalance a tremendous amount<br />

<strong>of</strong> tension. Figures 1 <strong>and</strong> 2 illustrate<br />

how the arch <strong>and</strong> suspension bridges<br />

are subject to the following three<br />

principles:<br />

• Tension—pulling force that tends<br />

to stretch an element. In a<br />

suspension bridge, the center<br />

span deck is pulling downward on<br />

the center span cables.<br />

• Compression—pushing force that<br />

tends to shorten an element. In an<br />

arch bridge, one wedge presses<br />

the wedge next to it. The<br />

abutments must withst<strong>and</strong> the<br />

outward compression or force <strong>of</strong><br />

all the wedges. In a suspension<br />

bridge, the cables press down on<br />

the towers.<br />

• Counterbalance—connecting<br />

elements that provide opposing<br />

forces. In the arch bridge, the<br />

abutments provide a<br />

counterbalance to the outward<br />

compression <strong>of</strong> the wedges. In<br />

the suspension bridge, the<br />

anchorages provide a<br />

counterbalance to the tension<br />

pulling on the cables.<br />

<strong>Bridge</strong> <strong>Elements</strong><br />

The three main elements for the arch<br />

bridge include:<br />

• Wedges—tapered elements that<br />

interlock <strong>and</strong> compress each other<br />

• Abutments—ground level<br />

supports to withhold outward<br />

compression<br />

• Scaffolds—temporary supports<br />

for positioning <strong>and</strong> holding<br />

wedges<br />

The six main elements for<br />

constructing the suspension bridge<br />

include:<br />

• Cables—staying elements to<br />

support the deck <strong>and</strong> load<br />

• Towers—vertical elements for<br />

hanging cables<br />

• Suspenders—elements for<br />

linking the cable to the deck<br />

• Anchorages—elements to<br />

counterbalance cable tension<br />

• Foundations—elements used to<br />

hold towers in position<br />

• Deck—surface element for load<br />

crossing<br />

<strong>Bridge</strong> Construction<br />

Given a bridge illustration with<br />

measurements, students should be<br />

able to construct a model similar to<br />

the drawing. Students should be able<br />

to cut the materials safely using a<br />

coping saw. Construction becomes a<br />

cooperative learning experience if the<br />

students work in small groups <strong>of</strong><br />

three or four members, with each<br />

member assigned a particular bridge<br />

element.<br />

The illustration <strong>of</strong> the arch bridge<br />

suggests 12 wedges. The wedges can<br />

be colored to represent two adjacent<br />

spectrums or rainbows placed end-toend.<br />

The two wedges at the top<br />

should be red, with one orange wedge<br />

on each side, followed by yellow,<br />

green, blue <strong>and</strong> violet at the base.<br />

Two or three students working<br />

together should be able to position the<br />

wedges. The students should try<br />

constructing the arch bridge with <strong>and</strong><br />

without a scaffold. If the scaffold fits<br />

the bottom <strong>of</strong> the arch, it should help<br />

to hold the wedges in place until the<br />

arch is completed.<br />

Learning Assessment<br />

Student learning may be assessed<br />

based on three skill categories:<br />

cooperative, psychomotor, <strong>and</strong><br />

cognitive. For cooperative skills<br />

assessment, the teacher may use an<br />

observation sheet to record how well<br />

the team members work together <strong>and</strong><br />

problem-solve to construct a st<strong>and</strong>ing<br />

bridge. In addition to the teacher’s<br />

observation <strong>of</strong> psychomotor skills,<br />

the students should evaluate each<br />

team’s bridge construction based on<br />

a point system. Points are awarded<br />

based on how well each element<br />

fulfills its purpose, <strong>and</strong> how well the<br />

bridge demonstrates each principle.<br />

In regard to cognitive skills, the<br />

following set <strong>of</strong> questions will help to<br />

assess the students’ underst<strong>and</strong>ing <strong>of</strong><br />

FEATURE ARTICLE<br />

the elements <strong>and</strong> principles <strong>of</strong> bridge<br />

construction. The questions may be<br />

assessed informally, such as a class<br />

review session. A more formal<br />

assessment could be a worksheet<br />

requiring written responses <strong>and</strong>/or<br />

labeling elements <strong>and</strong> principles on a<br />

drawing (see illustrations).<br />

• Why are the wedges tapered so<br />

that the narrow ends are facing<br />

downward?<br />

• Why is it important to secure the<br />

abutments before constructing<br />

the arch?<br />

• How would a scaffold beneath the<br />

wedges be helpful in constructing<br />

the arch?<br />

• What happens to the towers<br />

when you disconnect the cables<br />

from the anchorages <strong>and</strong> add a<br />

deck load?<br />

• How do the abutments serve to<br />

counterbalance the compression<br />

<strong>of</strong> the wedges?<br />

• How do the anchorages serve to<br />

counterbalance the tension on the<br />

cables?<br />

• How do the suspenders help the<br />

cable to support the deck <strong>and</strong><br />

load?<br />

• What happens to the center span<br />

deck when you disconnect the<br />

cables <strong>and</strong> add a deck load?<br />

• Why is it important to secure the<br />

anchorages <strong>and</strong> foundations before<br />

connecting the cables?<br />

Conclusion<br />

As an additional learning activity,<br />

students should research bridge<br />

technology on the Internet <strong>and</strong> view a<br />

video on bridge design. The PBS<br />

series on “Building Big with David<br />

Macaulay” (Macaulay, 2000) provides<br />

a video on “<strong>Bridge</strong>s” from ancient<br />

times to present day. It helps to<br />

address the role <strong>of</strong> bridges in society<br />

<strong>and</strong> the influence <strong>of</strong> bridges on<br />

history, while also addressing ITEA<br />

St<strong>and</strong>ards 6 <strong>and</strong> 7 (ITEA, 2000/2002).<br />

By designing model bridges, students<br />

can begin to appreciate how<br />

engineers construct elements that<br />

produce tremendous force, such as<br />

Vision + Commitment = Success<br />

arches <strong>and</strong> cables. They soon realize<br />

why these forces must be stabilized<br />

by counterbalancing elements, such<br />

as abutments <strong>and</strong> anchorages. After<br />

experiencing the principles <strong>of</strong> tension,<br />

compression, <strong>and</strong> counterbalance,<br />

students can apply this underst<strong>and</strong>ing<br />

to other monumental structures, such<br />

as towers, tunnels, <strong>and</strong> domes.<br />

From IDSA<br />

Using Storyboarding Techniques to Identify <strong>Design</strong> Opportunities<br />

Kevin Reeder, IDSA<br />

The movie industry heavily relies on<br />

storyboards as an effective way to<br />

visually describe the process <strong>of</strong> a<br />

movie. The storyboard visually<br />

describes how the movie flows from<br />

beginning to end, how the characters<br />

are interacting, <strong>and</strong> where transitions<br />

<strong>and</strong>/or gaps exist in the storyline.<br />

The storyboard is an effective tool in<br />

industrial design as well. A storyboard<br />

visually describes how users will<br />

interact with the product from start to<br />

finish <strong>and</strong> depicts the individual steps<br />

in that process that need further<br />

examination <strong>and</strong> analysis. This<br />

detailed examination leads to<br />

innovative product solutions that<br />

successfully address a greater amount<br />

<strong>of</strong> the users’ needs <strong>and</strong> expectations.<br />

In the classroom, when students<br />

employ storyboards, they are better<br />

able to underst<strong>and</strong> the complexity <strong>of</strong> a<br />

product’s use <strong>and</strong> visualize areas for<br />

improvement.<br />

When students employ storyboards, they<br />

are better able to underst<strong>and</strong> the complexity<br />

<strong>of</strong> a product’s use <strong>and</strong> visualize areas for<br />

improvement.<br />

This article discusses storyboarding in<br />

terms <strong>of</strong> its value in communicating<br />

what the designed product will do <strong>and</strong><br />

how people will interact with it. It will<br />

also discuss storyboarding as a tool<br />

for identifying opportunities for innovation.<br />

The article will use examples<br />

from student course work to support<br />

its premise <strong>and</strong> <strong>of</strong>fer a project that<br />

employs the same techniques for use<br />

in the classroom.<br />

Storyboards<br />

Through research activities, industrial<br />

designers underst<strong>and</strong> how people<br />

interact with existing products.<br />

Storyboarding these activities allows<br />

the designer to visualize the user’s<br />

needs <strong>and</strong> interactions throughout the<br />

process <strong>of</strong> using a product. In this<br />

way, designers can focus on <strong>and</strong><br />

resolve difficult steps in completing a<br />

task while designing for the whole<br />

process. For instance, students at<br />

Georgia Tech recently designed a<br />

medical delivery cart for a hospital in<br />

Atlanta. Through research <strong>and</strong><br />

storyboarding, the students were able<br />

to visualize <strong>and</strong> juggle the design<br />

issues <strong>of</strong> storing medication, charging<br />

power sources, moving through<br />

crowded spaces, <strong>and</strong> dispensing<br />

medication. Solutions <strong>of</strong>fered bases<br />

with wider sections, swiveling,<br />

retractable surfaces, <strong>and</strong> latch-on<br />

shelves while still presenting an<br />

appropriate image, <strong>and</strong> a solid<br />

structure within a manufacturing<br />

budget. Through this project the<br />

students were better able to<br />

manipulate the myriad <strong>of</strong> design<br />

issues that needed to be addressed in<br />

order to design a superior medical<br />

delivery cart.<br />

Storyboards can also be used to help<br />

designers identify opportunities for<br />

innovation. The operational process<br />

THE TECHNOLOGY TEACHER • April 2005 9


for a common electrical kitchen<br />

product may be:<br />

1. Remove the product from storage<br />

2. Plug the power cord into the outlet<br />

3. Turn it on<br />

4. Complete the task<br />

5. Turn it <strong>of</strong>f<br />

6. Remove the power cord from the<br />

outlet<br />

7. Clean the product<br />

8. Replace the product to storage<br />

IDSA<br />

The process may be prioritized to<br />

step number 4, “Complete the task.”<br />

By storyboarding this process, the<br />

designer can visualize <strong>and</strong> develop<br />

solutions for a step in the process<br />

that is not prioritized <strong>and</strong> perhaps not<br />

addressed by competitive products.<br />

In this manner, the new product<br />

surpasses market expectations by<br />

<strong>of</strong>fering more than “complete the<br />

task” to the consumer. As an<br />

academic exercise, students can<br />

visually underst<strong>and</strong> how the priority<br />

<strong>of</strong> the <strong>Design</strong> Objectives may change<br />

through the process <strong>of</strong> using the<br />

product. For example, in step 1,<br />

storing the power cord may be an<br />

important issue, while in step 4, cord<br />

storage has no importance.<br />

An example <strong>of</strong> employing visual<br />

storyboarding as a means to achieve<br />

innovation is shown in Figure 2,<br />

Lunchbox Storyboard. In this<br />

example, the designer addressed the<br />

stable market <strong>of</strong> lunch boxes, where<br />

change <strong>and</strong> innovation are limited to<br />

product graphics or surface<br />

materials. In this case, the designer<br />

storyboarded the process <strong>of</strong><br />

commuting to the <strong>of</strong>fice with a<br />

lunchbox <strong>and</strong> briefcase. By<br />

addressing this issue in general <strong>and</strong><br />

in particular, the designer was able to<br />

generate several innovative product<br />

solutions that address potentially<br />

new market segments in pr<strong>of</strong>essional<br />

lunch boxes.<br />

Figure 2. The Lunchbox Storyboard examines the possible uses.<br />

Constructing Visual Storyboards<br />

Visual Storyboards are exploration,<br />

analysis, conceptualization, <strong>and</strong><br />

communication tools <strong>and</strong>, as such,<br />

can be constructed in several ways.<br />

Movie storyboards are <strong>of</strong>ten h<strong>and</strong>drawn<br />

for speed <strong>and</strong> visualization <strong>of</strong><br />

the story <strong>and</strong> action. For industrial<br />

designers, both photographic <strong>and</strong><br />

h<strong>and</strong>-drawn methods are acceptable.<br />

Photographic recording (film, digital<br />

camera/video) <strong>of</strong> the research<br />

activities provides detailed images<br />

that can examined <strong>and</strong> presented<br />

digitally or as a printed hardcopy. In<br />

cases where photo documentation is<br />

not appropriate, recording role-playing<br />

exercises can help the design team to<br />

formulate questions for further<br />

examination (see Figure 1). H<strong>and</strong>drawn<br />

methods are most appropriate<br />

when quick examination <strong>and</strong><br />

conceptualization are the goals. It is<br />

important to note that h<strong>and</strong>-drawn<br />

storyboards are not limited by the skill<br />

<strong>of</strong> the designer <strong>and</strong>, as such, a stick<br />

figure is as valid a communication<br />

image as an artistically rendered<br />

figure. Regardless <strong>of</strong> the media, the<br />

storyboard allows the designer to<br />

examine the individual steps while<br />

remaining aware <strong>of</strong> the overall<br />

process.<br />

A Toothbrush Storage<br />

Device Project<br />

This project is constructed to<br />

encourage students to examine an<br />

apparently simple process in order to<br />

develop supportive products.<br />

Brushing teeth is appropriate for this<br />

project because students are familiar<br />

with the process <strong>and</strong> it can be<br />

delineated photographically or by<br />

h<strong>and</strong> drawings. Whatever the media,<br />

the goal is to study the process in<br />

fine detail in order to find a step that<br />

is best supported by hardware.<br />

To begin, the students, in groups <strong>of</strong><br />

two or three, should write/record<br />

their personal processes <strong>of</strong> brushing<br />

teeth in a step-by-step fashion <strong>and</strong><br />

share this with the group. The group<br />

then compares the different<br />

processes, with particular emphasis<br />

placed on individual variations. In<br />

doing this, students will, hopefully, be<br />

encouraged to share personal<br />

experiences <strong>and</strong> gain an<br />

underst<strong>and</strong>ing <strong>of</strong> the different uses<br />

for the new product. With this<br />

information, the design team is ready<br />

to construct the storyboard.<br />

The group will decide to either sketch<br />

the process in perspective or multi-<br />

10 April 2005 • THE TECHNOLOGY TEACHER


view projection (stick figures are<br />

sufficient) or to record the process<br />

photographically. Both methods have<br />

benefits. If sketching the process, the<br />

storyboard can be constructed from<br />

the personal processes described<br />

above. Photographically, a digital<br />

camera or digital video camera can<br />

easily record the step-by-step<br />

process <strong>of</strong> each member. At this<br />

point, the storyboard becomes a<br />

design tool. The design group scours<br />

the storyboard searching for<br />

instances where a new product<br />

would enhance or support the<br />

process. For instance, the group may<br />

find that an inconsistent placement <strong>of</strong><br />

the toothpaste causes frustration<br />

among the people preparing to brush.<br />

In this case, a storage device that is<br />

designed to retain the toothpaste<br />

(considering the variation in<br />

toothpaste packages) <strong>and</strong> encourage<br />

consistent placement <strong>of</strong> the toothpaste<br />

may be a really innovative,<br />

blockbuster <strong>of</strong> a new product idea.<br />

The final step in the project may be<br />

to build a model <strong>of</strong> the product idea<br />

<strong>and</strong> test it at each group member’s<br />

home. It is helpful to record the<br />

results <strong>and</strong> compare this to the<br />

storyboard. The model can be built <strong>of</strong><br />

foamcore, plastic sheet, or thin wood<br />

panels as the goal is to test the idea,<br />

not to produce the product. The<br />

project could exp<strong>and</strong> to include<br />

prototyping the new product based<br />

on the results <strong>of</strong> the test model <strong>and</strong><br />

also exp<strong>and</strong> to include a short<br />

production run to test on a larger<br />

group <strong>of</strong> potential users/consumers.<br />

Conclusion<br />

Storyboarding is a valuable tool to<br />

industrial designers <strong>and</strong> even more<br />

valuable to industrial design students.<br />

The technique encourages designers<br />

to examine, analyze, conceptualize,<br />

<strong>and</strong> communicate the different steps<br />

that constitute the interaction <strong>of</strong> a<br />

product to the person using it.<br />

Storyboarding can help student<br />

designers to better underst<strong>and</strong> the<br />

broad scope <strong>of</strong> product development<br />

as well as the value <strong>of</strong> designing the<br />

details while still considering the<br />

overall objective for the product.<br />

Get to Know an ITEA Member<br />

Brian Lien<br />

Technology Education Teacher, Princeton High School<br />

Cincinnati, Ohio<br />

What is your favorite thing about being a technology teacher?<br />

My favorite thing about being a technology education teacher is being able to teach the<br />

higher <strong>and</strong> lower achieving students in the same class <strong>and</strong> seeing them work together to<br />

solve problems. I really enjoy seeing my students underst<strong>and</strong> a math or science concept in a<br />

way that they never had in their math or science class. Because I teach high school, I enjoy<br />

watching the students grow <strong>and</strong> mature. As they become older <strong>and</strong> wiser, they delve deeper<br />

into the classes they take. This gets me excited <strong>and</strong> helps me stay fresh with what I am teaching.<br />

Why did you join ITEA?<br />

I joined ITEA because, as a college student, I had a wonderful college pr<strong>of</strong>essor who taught me that if I wanted to be<br />

treated like a pr<strong>of</strong>essional I had to act <strong>and</strong> dress like a pr<strong>of</strong>essional. When I began teaching, I met several teachers who<br />

were members <strong>of</strong> ITEA. Because <strong>of</strong> them, I became actively involved <strong>and</strong> took on leadership roles. I’ve benefited by<br />

meeting many wonderful people. These people have become lifelong friends <strong>and</strong> valuable sources <strong>of</strong> information.<br />

Please share your favorite teaching tip.<br />

Good parental contact is the best teaching tip I can <strong>of</strong>fer. Prior to the beginning <strong>of</strong> each class, I send a letter to my<br />

students' parents informing them <strong>of</strong> my teaching philosophy, expectations, <strong>and</strong> classroom rules. I also tell my parents<br />

that, if we work together, we will have a great year. I send home grades each week. I also send a postcard home once<br />

a quarter highlighting something positive about their child. Because <strong>of</strong> this, I get great parental support.<br />

WHERE THE WOMEN ARE: RESEARCH FINDINGS ON<br />

GENDER ISSUES IN TECHNOLOGY EDUCATION<br />

FEATURE ARTICLE<br />

W.J. Haynie, III<br />

This article reports some research<br />

findings about gender issues in<br />

technology education <strong>and</strong> relates<br />

some actual events that cause<br />

concern for our pr<strong>of</strong>ession. It also<br />

includes a Self-Check Questionnaire<br />

that teachers <strong>and</strong> other pr<strong>of</strong>essionals<br />

can use to examine their own<br />

behaviors <strong>and</strong> speech patterns,<br />

which could be turning females away<br />

from their classes or our pr<strong>of</strong>ession.<br />

It is hoped that underst<strong>and</strong>ing some<br />

<strong>of</strong> the perceptions <strong>of</strong> women in the<br />

pr<strong>of</strong>ession may help us all make it a<br />

more comfortable environment for<br />

females.<br />

Prior to 1980, the industrial arts<br />

curriculum failed to attract many<br />

female students or teachers, but<br />

there were some early indicators that<br />

the more contemporary technology<br />

curriculum would be more appealing<br />

to females (Cummings, 1998; Hill,<br />

1998; S<strong>and</strong>ers, 2001; <strong>and</strong> Zuga,<br />

1998). Simultaneously, due to<br />

changes in society, women were<br />

more accepted in traditionally maledominated<br />

pr<strong>of</strong>essions, <strong>and</strong> st<strong>and</strong>ards<br />

<strong>of</strong> acceptable behavior in crossgender<br />

social interactions were<br />

redefined (Foster, 1996; Haynie,<br />

1999; Stevens, 1996; <strong>and</strong> Wolters &<br />

Fridgen, 1996). Still, few women<br />

enter technology education even<br />

today. S<strong>and</strong>ers (2001) noted that,<br />

despite some gains in diversity,<br />

“technology education is still taught<br />

mostly by middle-aged white men”—<br />

the troubling question is: Why?<br />

Background<br />

The small body <strong>of</strong> pr<strong>of</strong>essional<br />

literature concerning the lack <strong>of</strong><br />

Once investigations discover issues to<br />

address, the pr<strong>of</strong>ession can make the<br />

changes needed to attract <strong>and</strong> retain more<br />

female students <strong>and</strong> teachers.<br />

women in technology education, the<br />

need for more women, <strong>and</strong> the<br />

historical reasons <strong>and</strong> potential<br />

factors keeping females out has been<br />

spotty but useful (ITEA, 1994;<br />

Liedtke, 1995; Markert, 1996;<br />

Silverman & Pritchard, 1996;<br />

Trautman, Hayden, & Smink, 1995;<br />

<strong>and</strong> Volk & Holsey, 1997). Most <strong>of</strong><br />

this literature, however, consists <strong>of</strong><br />

opinion papers, library research, <strong>and</strong><br />

journal articles; there is very little<br />

original or data-driven empirical<br />

research on gender issues in<br />

technology education.<br />

What research is needed on women’s<br />

issues in technology education?<br />

Markert (1996) indicated that<br />

educators should note a wide<br />

assortment <strong>of</strong> behaviors they display<br />

(possibly unknowingly) that “create a<br />

chilly classroom or null academic<br />

environment for their female<br />

students” (p. 28). These behaviors<br />

must be identified <strong>and</strong> changed<br />

because “Speeches <strong>and</strong> reports that<br />

extol the benefits <strong>of</strong> gender equality<br />

are nothing more than empty rhetoric<br />

if they are not followed up with<br />

commensurate action” (Akubue,<br />

2001, p. 71). The empirical research<br />

conducted thus far, though helpful in<br />

identifying issues <strong>and</strong> demonstrating<br />

that more studies are needed, has<br />

done little to solve the problem.<br />

Rigorous quantitative <strong>and</strong> qualitative<br />

study is needed. Once investigations<br />

discover issues to address, the<br />

pr<strong>of</strong>ession can make the changes<br />

needed to attract <strong>and</strong> retain more<br />

female students <strong>and</strong> teachers. More<br />

<strong>and</strong> more, funding agencies such as<br />

NSF are dem<strong>and</strong>ing clear results from<br />

empirical research as the basis for<br />

spending their money. The works<br />

discussed here help to lay such a<br />

foundation that could be used to seek<br />

funding for further work.<br />

Recently, two research efforts have<br />

shed some light on gender issues in<br />

technology education (Haynie, 1999,<br />

& 2003). The 1999 effort was a<br />

survey based upon hard data that<br />

provided a basis for further research.<br />

The 2003 study was termed a “Quasi<br />

Ethnographic Interview Approach” in<br />

its title. That was an apt identifier<br />

because it did report data collected<br />

via interviews, but there were<br />

variations from traditional<br />

methodology. In that article, the<br />

author claimed that the triangulation<br />

required to draw useful conclusions<br />

was achieved via the survey, the<br />

interviews, <strong>and</strong> his own purposeful<br />

observations since 1966 (when he<br />

first developed interest in this topic).<br />

Methods <strong>and</strong> Findings <strong>of</strong> Two<br />

Related Studies<br />

In general terms, the methods <strong>of</strong> the<br />

1999 study consisted <strong>of</strong> a survey <strong>of</strong><br />

technology education pr<strong>of</strong>essionals at<br />

the 1997 Technology Student<br />

Association conference. Of 150<br />

instruments distributed, 95 were<br />

completed (63% response rate).<br />

Thirty-nine women <strong>and</strong> 56 men<br />

participated in the survey. The survey<br />

consisted <strong>of</strong> 52 items intended to<br />

determine respondents’ perceptions<br />

on issues or situations. Each<br />

statement was followed by a<br />

continuum that respondents marked<br />

with an "X" to indicate their<br />

perception (Mueller, 1986). Readers<br />

who desire details <strong>of</strong> the specific<br />

methods <strong>and</strong> findings are encouraged<br />

to read the full report in the Journal<br />

<strong>of</strong> Technology Education (Haynie,<br />

1999), which is available online at<br />

http://scholar.lib.vt.edu/ejournals/JTE/.<br />

The findings <strong>of</strong> the 1999 survey<br />

(Haynie) included: “(1) all technology<br />

education pr<strong>of</strong>essionals should regard<br />

the school environment as a setting<br />

that requires a more conservative<br />

demeanor than society at large, (2)<br />

they should realize that their colleagues<br />

are likely a little more conservative than<br />

the values implied by contemporary<br />

society, (3) they should be sensitive to<br />

constantly monitor the appropriateness<br />

<strong>of</strong> their own actions <strong>and</strong> adjust them<br />

according to the reactions <strong>of</strong> others,<br />

<strong>and</strong> (4) should treat all persons with<br />

respect <strong>and</strong> fairness—judging them on<br />

their performance <strong>and</strong> ignoring all other<br />

potentially divisive factors.” (p 39)<br />

The second effort was qualitative<br />

research based on ethnographic<br />

interview technique. The researcher<br />

followed guidelines in a classic work<br />

by Spradley (1979) for conduction <strong>of</strong><br />

fruitful ethnographic interviews. Borg<br />

<strong>and</strong> Gall (1989), Burgess (1985),<br />

Goetz <strong>and</strong> LeCompte (1984), <strong>and</strong><br />

Merriam (1988) were also consulted<br />

for help with design <strong>of</strong> the study <strong>and</strong><br />

instrument. A paper instrument was<br />

used to record data, <strong>and</strong> the<br />

interviews were tape recorded. To<br />

make the participants feel valued<br />

(Spradley, 1979) <strong>and</strong> to allow for a<br />

lengthy interview in comfort, the<br />

interviews were conducted<br />

individually in restaurants during a<br />

meal or dessert. Twelve women from<br />

various perspectives within the<br />

pr<strong>of</strong>ession were interviewed. TTT<br />

readers desiring to know more about<br />

the demographics <strong>of</strong> the informants,<br />

details <strong>of</strong> the instrument, <strong>and</strong> a full<br />

discussion <strong>of</strong> the methodology are<br />

directed to the complete 14-page<br />

report in the Journal <strong>of</strong> Technology<br />

Education (Haynie, 2003). (Note: This<br />

journal is available in hardcopy <strong>and</strong><br />

also online at http://scholar.lib.vt.edu/<br />

ejournals/JTE/ .)<br />

In the interviews <strong>of</strong> the 2003 study,<br />

the women reported the following<br />

perceptions: a basic comfort level<br />

<strong>and</strong> improvement since the<br />

curriculum change toward computers<br />

<strong>and</strong> away from heavy industry; a<br />

perceived difference between older<br />

<strong>and</strong> younger men in the pr<strong>of</strong>ession—<br />

a few <strong>of</strong> the older men were<br />

perceived to hold outdated or biased<br />

views; <strong>and</strong> a field historically<br />

dominated <strong>and</strong> governed by an “old<br />

boys club” with conformist values—<br />

more mature women felt they were<br />

pioneers who broke new ground<br />

when they entered this field.<br />

The news was generally good.<br />

Despite a few negative comments<br />

<strong>and</strong> examples, overall the informants<br />

reported that they felt very<br />

comfortable most <strong>of</strong> the time in<br />

technology education (TE), students<br />

respect them, they wish more girls<br />

would take courses <strong>and</strong> consider a<br />

TE pr<strong>of</strong>ession, <strong>and</strong> most men make<br />

appropriate efforts to insure their<br />

comfort. Actions the pr<strong>of</strong>ession could<br />

take to increase enrollment <strong>of</strong><br />

females <strong>and</strong> attract more female<br />

teachers include: equity camps,<br />

online courses that permit lateral<br />

entry teachers to prepare without<br />

ab<strong>and</strong>oning jobs or children,<br />

technology camps, lateral entry<br />

opportunities for a second career in<br />

TE, high visibility events such as TSA<br />

<strong>and</strong> st<strong>and</strong>ards research efforts, <strong>and</strong><br />

possibly affirmative action efforts to<br />

attract women.<br />

In answer to other questions in the<br />

interviews, one informant pointed out<br />

that there are no females on the<br />

current ITEA Board (at that time) <strong>and</strong><br />

that the few who served before were<br />

“alone.” In most instances, though,<br />

the women felt that pr<strong>of</strong>essionals in<br />

technology education correctly<br />

recognized the expected language<br />

<strong>and</strong> behavior patterns in cross-gender<br />

relationships, <strong>and</strong> they acted<br />

accordingly. One woman followed<br />

this by saying there are no “skeletons<br />

in the closet” to find. Some questions<br />

attempted to find out the degree to<br />

which females advocated for<br />

themselves <strong>and</strong> others in various<br />

situations. In one <strong>of</strong> these items,<br />

when asked how they manage<br />

situations in which students crossed<br />

the line <strong>of</strong> decency, most informants<br />

agreed they would reprim<strong>and</strong><br />

students who used derogatory terms<br />

in description <strong>of</strong> homosexuals, or<br />

commented on another student’s<br />

body type or sex appeal.<br />

There were, however, reports <strong>of</strong><br />

isolated negative events. Actual<br />

<strong>of</strong>fensive events experienced<br />

included:<br />

• “At an ITEA conference, a former<br />

classmate hugged me too closely,<br />

clinging in the presence <strong>of</strong> my<br />

spouse.”<br />

• “At a conference an older man<br />

made a comment about the ‘good<br />

looking woman’ <strong>and</strong> it made me<br />

feel like a token instead <strong>of</strong> a<br />

valued pr<strong>of</strong>essional.”<br />

• “One pr<strong>of</strong>essor frequently made me<br />

feel like I stood out; it was isolated<br />

to only one person but it was<br />

obvious to everyone. I do not think<br />

he even knew he was <strong>of</strong>fending<br />

me.”<br />

• “One former faculty colleague<br />

used <strong>of</strong>fensive language<br />

frequently. Another actually made<br />

a sexual advance.”<br />

• “A man whom I seldom see except<br />

at conferences is a close hugger<br />

<strong>and</strong> sometimes makes ‘fresh’<br />

comments. I believe he thinks he is<br />

being cute or funny—I try to avoid<br />

him.”<br />

• “At the national conference I was<br />

talking to a salesman at an<br />

exhibitor’s booth <strong>and</strong> a male<br />

colleague barged in, grabbed the<br />

salesman’s h<strong>and</strong>, <strong>and</strong> drew him<br />

away as if I were not even there.<br />

It made me feel that I was not<br />

taken seriously.”<br />

• “Personally, I have not had lots <strong>of</strong><br />

bad experiences, but other<br />

females have been coddled or<br />

minimized, <strong>and</strong> we could<br />

encourage <strong>and</strong> mentor females<br />

better.”<br />

When given an open-ended<br />

opportunity to speak about things that<br />

make them feel uncomfortable in our<br />

pr<strong>of</strong>ession, the women who responded<br />

noted: Inability <strong>of</strong> the pr<strong>of</strong>ession to<br />

define ourselves to others; technical<br />

challenges (i.e. fix the s<strong>and</strong>er);<br />

isolation—I’m the only TE teacher at<br />

the school; rift between traditional<br />

industrial arts (IA) <strong>and</strong> modern TE<br />

teachers; there is a glass ceiling<br />

preventing advancement, but it may<br />

not be gender-specific; lack <strong>of</strong> broad<br />

technical experience; <strong>and</strong> age—I’m<br />

the youngest teacher at my school.<br />

Obviously, some <strong>of</strong> these concerns are<br />

not gender-specific <strong>and</strong> many new<br />

teachers would share them.<br />

The next question asked “What is the<br />

best thing about working in TE?”<br />

Several highlights <strong>of</strong> the responses<br />

included:<br />

• Feeling needed <strong>and</strong> that the<br />

subject is important (2).<br />

• Fun (5), Variety (3), Exciting (2),<br />

Creativity (2).<br />

• The people <strong>and</strong> the curriculum.<br />

• Family atmosphere.<br />

As confirmation <strong>of</strong> the survey <strong>and</strong><br />

interview results through observation<br />

(to provide triangulation) the<br />

researcher felt compelled to also<br />

report (in the 2003 study) two recent<br />

events that he witnessed that he<br />

believed illustrated uncomfortable<br />

treatment <strong>of</strong> women by men in our<br />

pr<strong>of</strong>ession. Both were in public<br />

forums at pr<strong>of</strong>essional conferences in<br />

which a leading member <strong>of</strong> the<br />

organization made an inappropriate<br />

<strong>and</strong> embarrassing comment from the<br />

podium. In one <strong>of</strong> the events a man<br />

at the podium giving an award made<br />

reference to the male recipient<br />

spending time at “Hooters” (a<br />

restaurant chain that proudly flaunts<br />

its exclusive employment <strong>of</strong><br />

provocatively clad young women as<br />

waitpersons). (Note: Since the<br />

original draft <strong>of</strong> this report, the author<br />

has heard two more Hooters stories<br />

from the podia <strong>of</strong> national<br />

pr<strong>of</strong>essional meetings in TE). In the<br />

other event the chair forgot a<br />

woman’s name <strong>and</strong> called her<br />

“Marilyn.” When informed <strong>of</strong> his<br />

mistake, he said, “I got her confused<br />

with Marilyn Monroe.” The blonde,<br />

pr<strong>of</strong>essional, female guest hid her<br />

dismay gracefully, but later<br />

responded to an apology from the<br />

researcher: “Thanks for your remarks.<br />

I think you are right on the money<br />

about these sorts <strong>of</strong> episodes having<br />

the effect <strong>of</strong> holding back progress<br />

toward [technology education]<br />

becoming a truly inclusive, civil, <strong>and</strong><br />

progressive pr<strong>of</strong>essional field.”<br />

Perhaps her response, as an outside<br />

observer, best summarizes a key<br />

finding <strong>of</strong> this work. How many<br />

women have a similar impression the<br />

first time they meet technology<br />

education pr<strong>of</strong>essionals?<br />

Rate Yourself on Sensitivity to<br />

Gender Issues<br />

Though Table 1, presented here, was<br />

not a part <strong>of</strong> the research studies<br />

discussed in this article, it is<br />

presented so that teachers <strong>and</strong> other<br />

pr<strong>of</strong>essionals may reflect on how<br />

they may be perceived by female<br />

students <strong>and</strong> colleagues. The<br />

research clearly shows that most<br />

men in TE treat females with respect<br />

<strong>and</strong> avoid making them feel<br />

uncomfortable; does the atmosphere<br />

in your classroom invite females? The<br />

Self-Check Questionnaire will also<br />

help female colleagues insure that<br />

they are encouraging girls in their<br />

classes <strong>and</strong> other female colleagues.<br />

It may be helpful for females to<br />

consider the other side <strong>of</strong> the coin<br />

(male perspective) <strong>and</strong> for all<br />

pr<strong>of</strong>essionals to consider the<br />

perceptions <strong>of</strong> persons from any<br />

marginalized groups.<br />

Conclusions<br />

Now let’s return to the formal<br />

findings <strong>of</strong> the research studies<br />

reported here. There were no<br />

contradictions in the findings among<br />

the three sources <strong>of</strong> triangulation:<br />

Observations (36 years), the 1999<br />

survey, <strong>and</strong> the 2003 interviews.<br />

Women are generally well accepted<br />

<strong>and</strong> comfortable in the technology<br />

education pr<strong>of</strong>ession, but there are<br />

some problems that make them feel<br />

isolated, patronized, minimized,<br />

conspicuous, or otherwise<br />

uncomfortable. Many <strong>of</strong> the problems<br />

leading to these feelings <strong>of</strong> isolation<br />

are due to the attitudes <strong>and</strong> actions<br />

<strong>of</strong> a small minority <strong>of</strong> men within our<br />

pr<strong>of</strong>ession who hold outdated views.<br />

These problems will best be<br />

eliminated if more women are<br />

encouraged to enter the pr<strong>of</strong>ession<br />

<strong>and</strong> advance to positions <strong>of</strong><br />

leadership in which they may serve<br />

as role models. The general manner<br />

in which men <strong>and</strong> women interact in<br />

the pr<strong>of</strong>ession is healthy <strong>and</strong> normal<br />

within the context <strong>of</strong> our current<br />

social mores <strong>and</strong> st<strong>and</strong>ards <strong>of</strong><br />

behavior. Men within the pr<strong>of</strong>ession<br />

should be careful to avoid comments<br />

that call attention to the gender <strong>of</strong><br />

female students or colleagues. We<br />

should all emphasize the abilities <strong>and</strong><br />

attributes that make all people<br />

valuable within the pr<strong>of</strong>ession. The<br />

evolving nature <strong>of</strong> the curriculum,<br />

coupled with retirement <strong>of</strong> some key<br />

older men who hold the most biased<br />

viewpoints, will slowly work to<br />

reduce the frequency <strong>of</strong> negative<br />

events <strong>and</strong> make the pr<strong>of</strong>ession more<br />

attractive to women. More evidencebased<br />

research by other<br />

pr<strong>of</strong>essionals is needed on these <strong>and</strong><br />

related topics.<br />

RESOURCES IN TECHNOLOGY<br />

Wheels <strong>and</strong> Tires<br />

John M. Ritz, DTE<br />

Automobile wheels (rims <strong>and</strong><br />

hubcaps) have been catching the<br />

eyes <strong>of</strong> car enthusiasts for years.<br />

<strong>Design</strong>ers have used their creativity<br />

to make better products both<br />

structurally <strong>and</strong> aesthetically.<br />

Hubcaps were one <strong>of</strong> the early<br />

aesthetic accessories added to<br />

wheels to hide the nuts used to<br />

fasten the wheels onto the vehicle.<br />

Later, MAG wheels (originally made<br />

<strong>of</strong> magnesium alloys to take on a<br />

spoke effect) were developed to<br />

increase the strength <strong>and</strong> sporty<br />

appearance <strong>of</strong> the wheels. Both are<br />

found in the current market; many are<br />

replaced with fads held by automotive<br />

enthusiasts. Some believe that the<br />

wheels <strong>and</strong> tires are the most visible<br />

styling statement beyond the<br />

automobile’s color <strong>and</strong> shape. This<br />

Resources in Technology will look at<br />

automotive wheels <strong>and</strong> tires.<br />

Humans learned early that simple<br />

tools could make their work easier.<br />

Heavy objects, e.g., rocks, trees,<br />

boats, could be rolled by wedging<br />

small logs under them <strong>and</strong> pushing or<br />

pulling. No doubt this is where the<br />

concept <strong>of</strong> the wheel developed.<br />

History has shown that early wheels<br />

were more easily made by fastening<br />

planks together instead <strong>of</strong> using one<br />

piece <strong>of</strong> heavy wood. Later, spoke<br />

systems were developed to lighten<br />

the weight <strong>of</strong> the wheels while<br />

maintaining strength. Tires were<br />

added to the wheels to increase<br />

useful life <strong>and</strong> to make the ride less<br />

bumpy.<br />

Today’s vehicles that ride on l<strong>and</strong>,<br />

roadways, <strong>and</strong> railways, are all<br />

developments or extensions <strong>of</strong> the<br />

early two-wheeled cart. The structure<br />

Underst<strong>and</strong>ing the numbers on the sides <strong>of</strong><br />

tires might lead to longer life tires <strong>and</strong><br />

improved driving safety.<br />

or propulsion <strong>of</strong> the vehicles has<br />

changed, but the basic concepts <strong>of</strong><br />

moving a load or people have stuck<br />

to the basic vehicle concept. Today,<br />

no vehicle is more <strong>of</strong> a necessity<br />

than the automobile. Driving is a rite<br />

<strong>of</strong> passage for teenagers in<br />

developed countries.<br />

Automotive Wheels<br />

Early automotive wheels were no<br />

more than bicycle wheels. These<br />

spoked wheels had metal tires or<br />

rims to increase their life. Because <strong>of</strong><br />

durability <strong>and</strong> automobile weight,<br />

solid rims were designed. These<br />

were forged <strong>and</strong> welded together.<br />

Today, wheels are either made <strong>of</strong><br />

steel or other metallic alloys.<br />

Traditional steel rims are forged <strong>and</strong><br />

welded together. Alloy wheel<br />

construction is undertaken in three<br />

manufacturing methods. Forged<br />

wheels, thought to be the best<br />

manufacturing technique, are made<br />

by taking an alloy billet (solid piece <strong>of</strong><br />

material) <strong>and</strong> compressing it through<br />

heat <strong>and</strong> pressure. This produces a<br />

very strong, lightweight wheel. Low<br />

pressure cast wheels are made by<br />

pouring molten metal into a mold that<br />

is the shape <strong>of</strong> the desired wheel.<br />

Counter pressure casting, the third<br />

way to produce automotive wheels,<br />

uses a vacuum to pull the hot metal<br />

into the mold. This method reduces<br />

the presence <strong>of</strong> air voids in the<br />

formed metal.<br />

Specialty wheels are everywhere in<br />

the automotive market. Storefront,<br />

magazine, <strong>and</strong> newspaper ads show<br />

how wheels can change the looks <strong>of</strong><br />

your automotive product. Many try to<br />

personalize their vehicle with a new<br />

set <strong>of</strong> wheels. Spinners are a current<br />

fad <strong>and</strong> catch your eyes when they<br />

continue to spin after the vehicle<br />

comes to a stop. If you are in the<br />

market for new wheels or tires, some<br />

knowledge <strong>and</strong> research can prove to<br />

be helpful in buying products that not<br />

only look good, but also increase the<br />

performance <strong>of</strong> your ride.<br />

Manufacturers recommend that<br />

replacement wheels <strong>and</strong> tires on<br />

automotive products be matched with<br />

those from the original design<br />

specifications. With the increased<br />

concentration on looks <strong>and</strong><br />

performance, people want to make<br />

their vehicles look special. Some are<br />

plus- or minus-sizing their wheels <strong>and</strong><br />

tires to enhance looks <strong>and</strong><br />

performance. It is common to see<br />

larger diameter wheels placed on<br />

customized cars with low pr<strong>of</strong>ile tires.<br />

Trucks are adding all-terrain <strong>and</strong> mud<br />

tires for <strong>of</strong>f-road performance. Experts<br />

in the after-market wheel <strong>and</strong> tire<br />

business recommend that the overall<br />

size <strong>of</strong> replacement wheels should not<br />

exceed three percent <strong>of</strong> the<br />

manufacturer-specified wheels <strong>and</strong><br />

tires. If this size is exceeded,<br />

problems can occur with proper<br />

transmission shifting, which will<br />

decrease fuel efficiency. Braking can<br />

also become a problem, since many<br />

systems are assisted with<br />

programmed on-board computers <strong>and</strong><br />

antilock braking systems (ABS).<br />

Although wheels are important in the<br />

functioning <strong>of</strong> the automobile, most <strong>of</strong><br />

the development in the suspension <strong>of</strong><br />

automobiles has been in the tires that<br />

we ride upon.<br />

Automotive Tires<br />

The first pneumatic (inflatable) tire,<br />

used on bicycles, was developed in<br />

1845 by Robert Thomson<br />

(http://en.wilipedia.org.wiki/Tire). Its<br />

design provided a better ride, but it<br />

was ab<strong>and</strong>oned. This tire had a<br />

canvas inner tube <strong>and</strong> a leather outer<br />

tire. It was hard to fit <strong>and</strong> retain the<br />

air to keep the tires inflated.<br />

Two names that are found in the history<br />

<strong>of</strong> tire technology are Charles Goodyear,<br />

who invented the vulcanization <strong>of</strong> rubber<br />

in 1844, <strong>and</strong> John Dunlap, who<br />

patented the pneumatic tire with a<br />

rubber outer tread in 1888<br />

(http://en.wilipedia.org.wiki/Tire).<br />

Early tires were made <strong>of</strong> natural<br />

rubber. Because <strong>of</strong> dem<strong>and</strong>, a<br />

substitute was developed that is<br />

petroleum-based. It is known as<br />

synthetic rubber. Today, experimentation<br />

is being done with<br />

nanomaterials (very small engineered<br />

materials). These could increase the<br />

life <strong>of</strong> the tire. However, with all<br />

technologies, we need to consider<br />

what the nanomaterials may do after<br />

manufacture. The nanomaterials that<br />

wear <strong>of</strong>f on the roadway could get<br />

washed <strong>of</strong>f the road <strong>and</strong> end up in<br />

agricultural products. These may then<br />

be consumed through the food chain.<br />

across the tire to resist puncturing <strong>and</strong><br />

also keep the tires flat so that there is<br />

improved road contact. Performance<br />

tires also have cap plies (extra layers<br />

<strong>of</strong> polyester cords) to keep the belts in<br />

place at high speeds.<br />

The sidewalls <strong>of</strong> the tire provide for<br />

structural integrity. When the<br />

automobile rounds corners, the<br />

sidewalls add lateral stability <strong>and</strong><br />

keep the tire from collapsing. The<br />

sidewalls also protect the body plies<br />

<strong>and</strong> provide stability so the tire beads<br />

can keep contact with the wheels<br />

<strong>and</strong> prevent air loss.<br />

The tire beads are the steel rods that<br />

keep the tire in contact with the rim<br />

(wheels). The beads are covered with<br />

rubber to provide wheel-to-tire<br />

contact strength <strong>and</strong> lock the air into<br />

the tire when inflated.<br />

Tread is the tire surface that runs on<br />

the road. It is made <strong>of</strong> synthetic <strong>and</strong><br />

natural rubber. Wear bars are also<br />

built into the tire’s tread. They are<br />

rubber bars that run perpendicular to<br />

the tire tread. When the tread <strong>of</strong> the<br />

tire runs thin from usage, they indicate<br />

to the owner or maintenance person<br />

that the tires need to be replaced. The<br />

bars are set at 1/16th <strong>of</strong> an inch from<br />

the base <strong>of</strong> the tread. When the<br />

indicator appears across the tire, the<br />

tires need to be replaced because<br />

there is not enough tread remaining to<br />

provide proper road traction.<br />

All <strong>of</strong> these components, belts, plies,<br />

sidewalls, <strong>and</strong> tread, are assembled<br />

in a tire-building machine. The tire<br />

assemblers build the tire in the<br />

machine. After the parts are put<br />

together, the tire is referred to as a<br />

green tire. The tire then needs to be<br />

heated <strong>and</strong> pressurized. This ensures<br />

the tire components are held strongly<br />

together. The tire curing process is<br />

known as vulcanizing. Besides<br />

holding the tire together, this process<br />

puts the tread pattern on the tire<br />

along with the printed information, all<br />

the numbers, words, <strong>and</strong> symbols, on<br />

the outer sidewalls <strong>of</strong> the tire.<br />

What the Numbers Mean<br />

If you are in the market to purchase<br />

replacement tires for the family’s car,<br />

you might be confused by what you<br />

read on sales ads or what the sales<br />

person tells you. All tires should<br />

match on an automobile, unless the<br />

sizes are changed through<br />

manufacturer’s design. Some<br />

performance cars have larger wheels<br />

<strong>and</strong> tires on the rear for improved<br />

traction <strong>and</strong> stability. Following is a<br />

description <strong>of</strong> a sample set <strong>of</strong> tires<br />

with most <strong>of</strong> the numbers on the tire<br />

sidewall explained. See Figure 1 <strong>and</strong><br />

the accompanying photographs.<br />

Tire Construction<br />

Tires are made in a composite manner<br />

(layer built upon layer). There are<br />

various materials that are held<br />

together with the vulcanized synthetic<br />

rubber. The body <strong>of</strong> the tire consists<br />

<strong>of</strong> several layers <strong>of</strong> plastic (polyester)<br />

cords, steel-belts, bead bundles, <strong>and</strong> a<br />

synthetic rubber body <strong>and</strong> tread.<br />

Many tires have steel belts that<br />

reinforce the tire. These belts wrap<br />

Figure 1. There is more information included on the sidewall <strong>of</strong> a tire than we may realize<br />

other than raised white letters <strong>and</strong> the tire size. Information such as the U.S DOT (Department<br />

<strong>of</strong> Transportation) code, recommended tire pressure, tread wear rating, temperature <strong>and</strong> traction<br />

grades, tire ply composition <strong>and</strong> material <strong>and</strong> number <strong>of</strong> plies, <strong>and</strong> other details.<br />

For example, the high performance<br />

tires on a Chrysler Crossfire are<br />

P225/40ZR18 <strong>and</strong> P255/35ZR19. Note<br />

that the front <strong>and</strong> rear tires are <strong>of</strong><br />

different sizes. The P st<strong>and</strong>s for<br />

passenger tires. LT st<strong>and</strong>s for light<br />

truck <strong>and</strong> T st<strong>and</strong>s for temporary<br />

(undersized spare tires). The 225 <strong>and</strong><br />

255 indicate the width <strong>of</strong> the tire from<br />

sidewall to sidewall. This<br />

measurement is in millimeters (mm).<br />

This size is important for proper rim fit.<br />

The 40 <strong>and</strong> 35 are referred to as<br />

aspect ratio, the percentage <strong>of</strong> the<br />

tire width to the height measured<br />

from the bead to the top tread. A 35-<br />

aspect ratio for the 255 tread width<br />

mentioned above would be a side<br />

wall height <strong>of</strong> 76.5 mm.<br />

Z is the tire’s speed rating. Table 1<br />

lists various speed ratings. For the<br />

tire being described, its<br />

recommended top speed is 149<br />

miles/hour (mph) or 240<br />

kilometers/hour (km/h) <strong>and</strong> over, a<br />

top speed rating. R indicates that the<br />

tire is a radial (plies running<br />

perpendicular to the tread).<br />

Table 1. Tire Speed Ratings<br />

Q 99 mph (160km/h)<br />

R 106 mph (180 km/h)<br />

S 112 mph (180 km/h)<br />

T 118 mph (190 km/h)<br />

U 124 mph (200 km/h)<br />

H 130 mph (210 km/h<br />

V 149 mph (240 km/h<br />

W 168 mph (270 km/h) *<br />

Y 186 (300 km/h mph)*<br />

Z 149 mph (240 km/h) <strong>and</strong> over)<br />

*For tires with a maximum<br />

speed capability over 149 mph,<br />

tire manufacturers sometimes<br />

use the letters ZR. For those<br />

with a maximum speed<br />

capability over 186 mph, tire<br />

manufacturers always use the<br />

letters ZR (NHTSA).<br />

Figure 2. The wheel <strong>and</strong> tire assembly shown on this 2004 Ford Escape SUV are selected<br />

for their performance, h<strong>and</strong>ling, <strong>and</strong> economy. SUV’s tires are generally larger to<br />

accommodate <strong>of</strong>f-road driving conditions. However, typically SUVs are infrequently driven<br />

<strong>of</strong>f-road, so tire tread designs are less aggressive <strong>and</strong> favor highway driving conditions.<br />

St<strong>and</strong>ard tires for a Ford Escape are<br />

P235/70R16, Figure 2. Note the<br />

speed rating is not in the tire size<br />

description. However the tire sidewall<br />

does contain the following notation,<br />

104T. The 104 indicates the tire’s<br />

load rating, which translates to 900<br />

kilograms (kgs) or 1984 pounds per<br />

tire. This would mean the total<br />

vehicle weight, SUV plus its contents<br />

(people <strong>and</strong> load), should not exceed<br />

7936 pounds or 3600 kilograms. The<br />

more weight you have, the more<br />

pressure is exerted onto the tires.<br />

Excessive weight can cause<br />

structural damage to the tire <strong>and</strong><br />

subsequent failure. Tables are<br />

available to translate the load index<br />

<strong>of</strong> the tire, e.g., www1010tires.com/<br />

tiretech.asp. The T in the Escape’s<br />

printed tire information indicates the<br />

tire is rated for 118mph. For the<br />

Crossfire’s tires described in Figure 3,<br />

the load index was listed as 92 or<br />

1389 pounds (630 kgs) per tire.<br />

In addition to these specifications,<br />

tire sidewall printed information also<br />

includes its tread wear, traction, <strong>and</strong><br />

temperature ratings. These are found<br />

in a continuous notation <strong>and</strong> are<br />

determined by the U.S. government<br />

at its National Highway Traffic Safety<br />

Administration testing track in Texas.<br />

The index used is the Uniform Tire<br />

Quality Grading (UTQG) rating<br />

system. It tells the consumer the<br />

relative performance <strong>of</strong> the tire; it is<br />

not exact since people drive<br />

differently <strong>and</strong> on different types <strong>of</strong><br />

roads. The index can be located at<br />

www.nhtsa.dot.gov/cars/testing/UTQ<br />

G/pages/TireRatings.cfm.<br />

Tread wear provides a number to<br />

determine the life <strong>of</strong> the tire<br />

compared to other similar tires. The<br />

rating is determined after 7200 miles<br />

<strong>of</strong> driving on the Texas test track. The<br />

higher the rating number, the longer<br />

you can expect the tire to last. It is<br />

not a precise number, but relative to<br />

the wear on other tires in controlled<br />

conditions. A 500-rated tire should<br />

last twice as long at a 250-rated tire.<br />

Although relative, the rating is<br />

important in comparative shopping.<br />

Traction ratings are also determined<br />

by the government on the test track.<br />

Traction ratings are AA, A, B, or C.<br />

AA is the top rating. It is a<br />

measurement <strong>of</strong> the ability <strong>of</strong> the tire<br />

to stop the vehicle in a straight line<br />

on wet roads. The tests are based on<br />

performance at 40 mph with the<br />

brakes locked.<br />

Figure 3. The Chrysler Crossfire is a high performance sports vehicle that emphasizes<br />

luxurious styling, speed, h<strong>and</strong>ling, <strong>and</strong> cornering capabilities. This product was designed<br />

rims <strong>and</strong> ZR-rated tires. Additionally, this vehicle features different sized tires on the front<br />

<strong>and</strong> rear <strong>of</strong> the vehicle to improve h<strong>and</strong>ing <strong>and</strong> cornering with P225/40ZR18 on the front <strong>and</strong><br />

The temperature ratings range from A,<br />

indoors in a controlled environment on<br />

a simulated road wheel test st<strong>and</strong>. The<br />

ratings are gauged on 30-minute<br />

successive runs. The temperature<br />

indication ratings measure the tire<br />

speed where heat from friction would<br />

cause the tire to fail. “A” ratings<br />

on the wheel machine at 114mph. B<br />

ratings are gauged at 99mph, while C<br />

ratings are gauged at 85mph<br />

(www.1010tires.com/tiretech.asp).<br />

Other sidewall markings include season<br />

ratings (MS for all seasons, AT for all<br />

terrain, <strong>and</strong> M+S for mud <strong>and</strong> snow),<br />

tire manufacturing date, manufacturing<br />

site, <strong>and</strong> tire inflation pressures.<br />

NHTSA reported that the Firestone<br />

Wilderness ATX tires, the ones that<br />

led to consumer lawsuits <strong>of</strong> Ford<br />

Explorer <strong>and</strong> Firestone in 2001, were<br />

rated as B for traction <strong>and</strong> C for<br />

temperature (www.dot.gov/affairs/<br />

nhtsa5101.htm). So, although price is<br />

important to consumers,<br />

underst<strong>and</strong>ing the numbers on the<br />

sides <strong>of</strong> tires might lead to longer-life<br />

tires <strong>and</strong> improved driving safety.<br />

Wheel <strong>and</strong> Tire Care<br />

There are many products on the<br />

market advertised to clean wheels.<br />

Besides road grime, brake dust also<br />

accumulates on the wheels. When<br />

you purchase specialty wheels, learn<br />

the metal (alloys) from which they<br />

are manufactured. When you<br />

purchase your wheel cleaning<br />

detergents they need to be<br />

appropriate for the metal used to<br />

manufacture the wheel. Usually the<br />

car washing soap you are using to<br />

wash your car will not cut the brake<br />

dust. Do not use extra strong<br />

household cleaners if the wheel<br />

manufacturer recommends against<br />

this. It could mar the finish <strong>of</strong> your<br />

wheels. Also, clean one wheel at a<br />

time, since the sun can dry cleaners<br />

<strong>and</strong> make them hard to remove.<br />

Car wax can be applied to nontextured<br />

wheels <strong>and</strong> it will assist in<br />

the cleaning process. Specialty<br />

sprays can be purchased from<br />

automotive stores that will also repel<br />

brake dust <strong>and</strong> road grime.<br />

Tires should be visually inspected to<br />

insure a safe ride. Some learn to look<br />

at their tires each time they enter<br />

their car. Others do this at regular<br />

maintenance intervals. Visual<br />

inspections can show excessive<br />

wear, puncture materials that may<br />

have lodged themselves in your tires,<br />

or low air pressures. Catching<br />

problems early can extend the life <strong>of</strong><br />

tires <strong>and</strong> prevent flats from<br />

puncturing objects.<br />

Maintaining proper air pressure in<br />

tires is important for proper wear. A<br />

recent NHTSA survey found that<br />

about 30% <strong>of</strong> cars <strong>and</strong> light trucks<br />

have at least one tire under inflated<br />

by 8psi or more.<br />

(www.nhtsa.gov/cars/testing/utqg/)<br />

Tires do lose pressure over time from<br />

the changes in heat, both from<br />

driving <strong>and</strong> the atmosphere. Improper<br />

inflation <strong>of</strong> tires can cause excessive<br />

<strong>and</strong> irregular wear, poor vehicle<br />

h<strong>and</strong>ling, <strong>and</strong> decreased gas mileage.<br />

Improper tire pressures can result in<br />

tire failure. Visual inspection can<br />

usually identify problems. A quality<br />

air gauge should be used to check<br />

correct tire pressures. Tires should be<br />

checked when they are cold, since<br />

driving warms the tires <strong>and</strong> increases<br />

their pressure. The optimum<br />

pressures are located on the sidewall<br />

<strong>of</strong> the tires <strong>and</strong> also in the owner’s<br />

manual. Some newer models <strong>of</strong><br />

automobiles have electronic sensors<br />

<strong>and</strong> circuitry, which display lights on<br />

the instrumentation if tire pressure is<br />

low. Also remember to check the<br />

pressure <strong>of</strong> your spare tire. Nothing is<br />

more irritating than having a flat tire<br />

<strong>and</strong> then finding the spare is also flat.<br />

Balancing <strong>of</strong> tires is undertaken when<br />

they are installed. They can come out<br />

<strong>of</strong> balance because <strong>of</strong> wear or in the<br />

original manufacturing process (tires<br />

can be heavier where the circular<br />

tread is cohered to complete the<br />

circle). Tires may be balanced on or<br />

<strong>of</strong>f a vehicle. Two types <strong>of</strong> balancing<br />

are static <strong>and</strong> dynamic. Dynamic<br />

balancing is accomplished by spinning<br />

the wheel assembly on a balancing<br />

machine at highway speeds <strong>and</strong> then<br />

adding the necessary wheel weights<br />

to counteract any imbalance.<br />

Typically, out-<strong>of</strong>-balance wheels will<br />

“bounce” or “wobble.” A balancing<br />

machine marks the spot in the circular<br />

tire where it is the heaviest. The<br />

balancing weights are put on the<br />

opposite side from where the tire/<br />

wheel is the heaviest. When you<br />

replace tires, this is when balancing<br />

usually occurs. Visual inspection should<br />

note if the weights used for balancing<br />

fall <strong>of</strong>f <strong>and</strong> need to be replaced. If the<br />

tires do not have unusual wear or<br />

create vibrations felt in the steering<br />

wheel, they probably do not need<br />

rebalanced during tire rotations.<br />

Since tires wear differently in the<br />

front <strong>and</strong> rear due to weight<br />

distribution, turning, <strong>and</strong> traction,<br />

they should be rotated at regular<br />

intervals. A good way to build this<br />

into your maintenance schedule is to<br />

have the tires rotated at every other<br />

oil change (6000 to 7500 miles).<br />

When you have a new set <strong>of</strong> tires<br />

installed on your vehicle, wheel<br />

alignment should be checked. The<br />

vehicle is aligned at manufacture, but<br />

it can get out <strong>of</strong> alignment (wheels<br />

running parallel to each other) by the<br />

wheels hitting other cars, curbing, or<br />

deep holes. When the wheels are out<br />

<strong>of</strong> alignment they cause unusual<br />

tread wear <strong>and</strong> h<strong>and</strong>ling <strong>and</strong> can<br />

damage the suspension <strong>of</strong> the<br />

vehicle. So to increase the life <strong>of</strong> your<br />

tires, it is important to get the<br />

alignment corrected if you notice<br />

unusual tire wear or driving h<strong>and</strong>ling.<br />

Using a proper maintenance<br />

schedule, tires can last for the<br />

mileage at which they are rated. It is<br />

not uncommon to get 50,000 miles<br />

on a set <strong>of</strong> tires that are rated for this<br />

mileage by keeping the tires properly<br />

inflated <strong>and</strong> rotated on a schedule.<br />

Government Involvement in the<br />

Tire Industry<br />

Safety ratings are important to<br />

consumers. As with all technology,<br />

consumers cannot be knowledgeable<br />

on all topics. Technology education is<br />

the school subject that should provide<br />

much <strong>of</strong> this knowledge <strong>and</strong> a<br />

consumer attitude that you can learn<br />

about new technologies by conducting<br />

consumer research. Governments<br />

assist citizens in many technical<br />

areas. Tire technology is one such<br />

area. Because <strong>of</strong> potential injury to<br />

consumers <strong>and</strong> others, the U.S.<br />

government established the National<br />

Highway Traffic Safety Administration<br />

<strong>and</strong> its Uniform Tire Quality Grading<br />

(UTQG) rating system. It is involved in<br />

the rating <strong>of</strong> new tires <strong>and</strong> also<br />

follows up if drivers are reporting<br />

incidents with current tires <strong>and</strong> other<br />

vehicle system failures.<br />

It is important that there are<br />

“watchdog” government groups,<br />

because the proper research may not<br />

go into the post-manufacturing<br />

performance <strong>of</strong> consumer products.<br />

Many tires <strong>and</strong> other consumer<br />

products are being manufactured in<br />

other countries. What are the driving<br />

conditions <strong>and</strong> automotive<br />

requirements in these countries?<br />

How do they align with what is<br />

needed in your country?<br />

Today many tire manufacturers are<br />

partnering with Chinese companies<br />

because <strong>of</strong> lower material <strong>and</strong> labor<br />

costs. Chinese companies are also<br />

trying to produce their own lines <strong>of</strong><br />

internationally accepted tires. They<br />

may succeed. However, as increasing<br />

automotive products enter the<br />

market, countries <strong>and</strong>/or companies<br />

may not be responsible for the<br />

performance quality <strong>of</strong> their<br />

manufactured products. This is why<br />

we need the government involved—<br />

consumer protection.<br />

Government is also involved in the<br />

proper disposal <strong>of</strong> tires. Because <strong>of</strong><br />

their composition, it is hard to recycle<br />

tires. Many have been dumped <strong>and</strong><br />

catch on fire. This causes toxic fumes<br />

<strong>and</strong> carbon black smoke. Disposal<br />

fees are imposed by the government<br />

<strong>and</strong> passed onto consumers by the<br />

tire retailers. These fees are used to<br />

aid in research to find better ways to<br />

dispose <strong>of</strong> the tires.<br />

Learning Lab Activity<br />

Research <strong>and</strong> discussion <strong>of</strong> wheels,<br />

tires, <strong>and</strong> their maintenance can be a<br />

valuable learning experience.<br />

Following are some viable technology<br />

literacy activities.<br />

1. Have students bring in the<br />

sidewall information from their<br />

primary vehicle’s tires. Determine<br />

speed, load, tread wear, traction,<br />

<strong>and</strong> temperature ratings. Discuss<br />

if any students were surprised<br />

with the tire performance<br />

indicators as compared to the<br />

car/truck model. Write vehicle<br />

models <strong>and</strong> tire markings on the<br />

board for comparisons.<br />

2. Shop online for tire pricing ads.<br />

Remember to look into the overall<br />

tire ratings <strong>and</strong> compare prices.<br />

Students might have to visit the<br />

Web pages <strong>of</strong> the tire<br />

manufacturers to check on details<br />

<strong>of</strong> the tire performance criteria.<br />

3. Have students research wheel<br />

cleaners by visiting automotive<br />

departments <strong>and</strong> stores. Discuss<br />

the cleaner information they found.<br />

4. Use Car Builder or Truck<br />

Builder computer s<strong>of</strong>tware<br />

programs to design a car or truck.<br />

Explore how changing wheel <strong>and</strong><br />

tire sizes can increase or decrease<br />

vehicle performance, such as<br />

speed, h<strong>and</strong>ling, <strong>and</strong> ride comfort.<br />

Summary<br />

Automotive wheels <strong>and</strong> tires require<br />

knowledge to underst<strong>and</strong> their<br />

specifications <strong>and</strong> use. While the<br />

durability <strong>and</strong> useful life <strong>of</strong> tires have<br />

increased substantially over the last<br />

several decades, in all probability you<br />

will purchase a number <strong>of</strong> vehicle<br />

tires over your lifetime. Knowing how<br />

they are made <strong>and</strong> what the numbers<br />

mean will assist you in making<br />

informed <strong>and</strong> intelligent consumer<br />

purchasing decisions. Basic tire<br />

maintenance such as tire air<br />

pressure, balancing, <strong>and</strong> rotation can<br />

extend the useful life <strong>of</strong> tires <strong>and</strong><br />

maintain their safety, performance,<br />

<strong>and</strong> h<strong>and</strong>ling features.<br />

THE TECHNOLOGY TEACHER • April 2005 21


APPLICATION TO<br />

PRESENT AT<br />

ITEA’s 68th Annual Conference<br />

Baltimore, MD<br />

March 23-25, 2006<br />

Theme: Living in a World with Smart Technology<br />

All technology education pr<strong>of</strong>essionals are invited to participate in the 68th annual ITEA conference as a presenter<br />

or chairperson. Those wishing to participate must complete the application form available online. The application<br />

deadline is June 15, 2005.<br />

We have moved from a society where human ingenuity <strong>and</strong> tools were used to obtain basic wants <strong>and</strong> needs to<br />

one <strong>of</strong> more sophistication where tools now think, interact, <strong>and</strong> respond. Because <strong>of</strong> the power <strong>of</strong> today’s<br />

technological processes, society <strong>and</strong> individuals need to decide what, how, <strong>and</strong> when to develop or use various<br />

technological systems. Since technological issues <strong>and</strong> problems have more than one available solution, decisionmaking<br />

should reflect the values <strong>of</strong> the people <strong>and</strong> help them reach their goals. Such decision-making depends<br />

upon all citizens, both individually <strong>and</strong> collectively, acquiring a basic level <strong>of</strong> technological literacy—the ability to<br />

use, manage, <strong>and</strong> underst<strong>and</strong> technology. This conference will address many <strong>of</strong> the above issues <strong>and</strong> problems, as<br />

we seek to live in a world with tools that think.<br />

The Conference Program Committee is seeking presentations, related to the theme, that:<br />

• Promote content connections with other fields <strong>of</strong> study.<br />

• Encourage active <strong>and</strong> experiential learning.<br />

• Provide the basis for developing meaningful, relevant, <strong>and</strong> articulated curricula at the local <strong>and</strong> state/provincial<br />

levels.<br />

• Are developmentally appropriate for students.<br />

• Develop a common set <strong>of</strong> expectations for what students should learn in the study <strong>of</strong> technology.<br />

Proposed presentations must address one or more <strong>of</strong> the following conference theme str<strong>and</strong>s as defined by the<br />

definitions from St<strong>and</strong>ards for Technological Literacy:<br />

Str<strong>and</strong> 1 - Nature <strong>of</strong> Technology<br />

Str<strong>and</strong> 2 - Technology <strong>and</strong> Society<br />

Str<strong>and</strong> 3 - <strong>Design</strong><br />

Str<strong>and</strong> 4 - Abilities for a Technological World<br />

Str<strong>and</strong> 5 - The <strong>Design</strong>ed World<br />

All presenters must be active members <strong>of</strong> ITEA by June 15, 2005. Presenters must also register for the<br />

conference. Go to www.iteawww.org for membership <strong>and</strong> conference registration information. ITEA does not<br />

provide honorariums or cover travel, registration fees, conference expenses, etc.<br />

Application deadline is June 15, 2005.<br />

DESIGNING NATURE’S WAY<br />

You have won a new<br />

car—any new car<br />

you want! What kind<br />

<strong>of</strong> car do you pick?<br />

Do you want a racy<br />

sports car, with a<br />

powerful V-8 engine,<br />

6-speed<br />

transmission, power<br />

convertible top,<br />

navigation system,<br />

polished aluminum<br />

wheels, <strong>and</strong> premium sound system with in-dash 6-CD<br />

player with MP3? Or maybe you’d rather have a roomy 4-<br />

wheel-drive sport utility job that could take you out in the<br />

wilds where no other car could go. Or how about a nice<br />

luxury sedan that could take you <strong>and</strong> your family on long<br />

trips in quiet, air-conditioned comfort <strong>and</strong> safety?<br />

There’s an automobile for just about any type <strong>of</strong><br />

transportation need (or dream) you can imagine. Auto<br />

designers make a list <strong>of</strong> needs <strong>and</strong> wants that a particular<br />

type <strong>of</strong> driver (or buyer) might have, then design a car,<br />

truck, or SUV that will sell . . . <strong>and</strong>, they hope, delight the<br />

buyer.<br />

But, <strong>of</strong> course car designers don’t start from scratch each<br />

year. They take parts <strong>of</strong> the previous years’ designs that<br />

worked well (such as the engine, transmission, brake<br />

system, <strong>and</strong> the particular materials used for each type <strong>of</strong><br />

part), then add new features or change things slightly to<br />

try to improve the finished product. So, in theory,<br />

automobiles should get better <strong>and</strong> better all the time. For<br />

the most part, they do. But at some point, designers will<br />

run out <strong>of</strong> new ideas to make the car better <strong>and</strong> more fit<br />

for any particular driver’s requirements.<br />

A Different Kind <strong>of</strong> “<strong>Design</strong>er”<br />

In the case <strong>of</strong> cars <strong>and</strong> other engineered objects, humans<br />

go about the design process in a very intentional way.<br />

They pretty much know what they are aiming for. They<br />

know how to test their designs to see if they will work in<br />

the real world. However, in the case <strong>of</strong> nature, the<br />

environment <strong>and</strong> the “laws <strong>of</strong> the jungle” make up the list<br />

<strong>of</strong> requirements that living things must meet, as well as<br />

the “tests” that they must pass in order to survive. For<br />

example, in order for an animal species to survive,<br />

individuals must be able to find, eat, digest, <strong>and</strong><br />

metabolize food; find <strong>and</strong> drink water; protect themselves<br />

from predators <strong>and</strong> harsh weather; <strong>and</strong> reproduce, passing<br />

along their successful characteristics to their <strong>of</strong>fspring. All<br />

the “design accessories,” such as eyes, nose, ears, teeth,<br />

claws, hooves, spots, stripes, fur, or fancy feathers,<br />

contribute to the success <strong>of</strong> the “design.”<br />

The plants <strong>and</strong> animals we know (<strong>and</strong> are!) today are the<br />

<strong>of</strong>fspring <strong>of</strong> billions <strong>of</strong> generations. If each generation had<br />

been an exact copy <strong>of</strong> its parents, then no changes in the<br />

instructions for the design, the “blueprint,” would ever<br />

occur <strong>and</strong> there would be only one “species” <strong>of</strong> living<br />

thing <strong>and</strong> it would never change. But changes in the<br />

blueprint do occur very frequently. Mistakes are made in<br />

the copying process. Harsh environmental influences, such<br />

as solar radiation <strong>and</strong> toxic substances, knock out or<br />

distort parts <strong>of</strong> the blueprint so the design cannot be<br />

copied exactly in the next generation. These changes in<br />

the instructions are called mutations. Most mutations<br />

result in “design flaws” in the next generation. But a few<br />

mutations actually result in improvements. The resulting<br />

<strong>of</strong>fspring are a little more successful at surviving <strong>and</strong><br />

reproducing than their cousins, <strong>and</strong> so pass on the<br />

mutation to more <strong>of</strong>fspring, thus changing the species the<br />

tiniest bit to make it better adapted to its environment.<br />

Lessons from Nature<br />

Sometimes engineers <strong>and</strong> inventors look to nature for<br />

inspiration. For example, how do animals solve the<br />

problem <strong>of</strong> getting from one place to another? Well, nature<br />

has come up with all sorts <strong>of</strong> legs, fins, flippers, wings,<br />

pseudopods, undulating muscles, <strong>and</strong> so on. (It took<br />

humans, however, to come up with wheels <strong>and</strong> roads.)<br />

Given billions <strong>of</strong> years <strong>and</strong> billions <strong>of</strong> “trial <strong>and</strong> error”<br />

experiments over billions <strong>of</strong> generations, natural processes<br />

have produced living things that have solved many other


complex problems in very effective <strong>and</strong> efficient ways that<br />

humans would probably never have thought <strong>of</strong>.<br />

Humans cannot think <strong>of</strong> every possible approach to a<br />

problem. Human invention seems to be limited by what has<br />

been done before <strong>and</strong> by our own brains’ wiring that makes<br />

us want to create things that “look right” <strong>and</strong> fit into some<br />

pigeonhole or category that we already know about. Nature<br />

itself doesn’t have categories <strong>and</strong> fixed notions <strong>of</strong> things.<br />

Nature is limited only by the laws <strong>of</strong> physics. So why can’t<br />

humans use something like those same natural processes<br />

<strong>and</strong> experiments to design new things?<br />

Well, trial <strong>and</strong> error is not really a very efficient way to<br />

design something. It’s much better to use your brain <strong>and</strong><br />

try to figure out what kind <strong>of</strong> design would work best<br />

before you go to all the trouble to build it <strong>and</strong> test it to see<br />

if it would work in the real world.<br />

Evolution in Fast-forward<br />

But what if we could give the “trial <strong>and</strong> error” design job to<br />

a very powerful computer? Suppose we want to design a<br />

new kind <strong>of</strong> mousetrap. We first have to tell the computer<br />

about mice <strong>and</strong> the laws <strong>of</strong> physics, so it will know what is<br />

physically possible out here in the real world (as opposed<br />

to inside the computer). Then we tell the computer what<br />

we want the mousetrap to do. In other words, we think <strong>of</strong><br />

a test the computer can run inside itself: the mousetrap<br />

must attract a mouse, then trap it without the mouse being<br />

able to carry the trap away or escape. Oh, <strong>and</strong> we don’t<br />

want to hurt the mouse—just catch it <strong>and</strong> relocate it from<br />

the city to the country. Then the computer could be<br />

programmed with a list <strong>of</strong> materials or tools (<strong>and</strong> their<br />

characteristics) that the computer could use to create the<br />

mousetrap: plastic, glass, wood, metal, cheese, etc.<br />

To give the computer a bit <strong>of</strong> a head start, we come up<br />

with quite a few designs <strong>of</strong> our own. We feed them (that<br />

is, the exact measurements, materials, <strong>and</strong> other<br />

characteristics) into the computer, <strong>and</strong> let the computer<br />

run its mousetrap testing program on them. The computer<br />

then takes the several designs that did the best, scrambles<br />

up their characteristics a little, then generates a new set <strong>of</strong><br />

designs: Mousetrap Generation<br />

#2. The computer then runs<br />

the same test on this batch <strong>of</strong><br />

designs to see which<br />

mousetraps would do the best<br />

job. It then picks out several <strong>of</strong><br />

the best designs, mixes them<br />

up a little, <strong>and</strong> spits out another<br />

bunch <strong>of</strong> mousetrap designs:<br />

Mousetrap Generation #3. The<br />

computer continues testing,<br />

picking the best performers,<br />

mixing up their traits, <strong>and</strong> creating yet another generation<br />

<strong>of</strong> designs over <strong>and</strong> over <strong>and</strong> over. Eventually, maybe after<br />

a million generations, one mousetrap passes the test<br />

perfectly <strong>and</strong> no further designs can do any better. The<br />

perfect non-destructive mousetrap! The computer prints<br />

out the design specifications, real people build <strong>and</strong> test it in<br />

the real world, <strong>and</strong> it works! But what does it look like? It<br />

just might not look like any mousetrap anyone has ever<br />

imagined before!<br />

An “Out-<strong>of</strong>-the-Box” Antenna <strong>Design</strong><br />

It is as computers have become very fast <strong>and</strong> very<br />

powerful that designing “nature’s way” has become<br />

practical. Engineers at NASA’s Ames Research Center in<br />

Silicon Valley, California, have used the technique <strong>of</strong><br />

evolutionary computation, also called artificial evolution, to<br />

design a tiny communications antenna to be used in the<br />

three small TV-sized satellites <strong>of</strong> the Space Technology 5<br />

(ST5) mission. Many r<strong>and</strong>om designs were tested in a<br />

computer—or, actually 35 computers working together.<br />

The computer judged their performance against certain<br />

goals for the design: efficiency, a narrow or wide broadcast<br />

angle, frequency range, <strong>and</strong> so on.<br />

As in nature, only the best performers were kept, <strong>and</strong> these<br />

served as parents <strong>of</strong> a new generation. To make the new<br />

generation, the traits <strong>of</strong> the best designs were r<strong>and</strong>omly<br />

mixed by the computer to produce fresh, new designs—<br />

just as a father <strong>and</strong> mother’s genes are mixed to make<br />

unique children. This new generation was again tested in<br />

the computer simulation, <strong>and</strong> the best designs became the<br />

parents <strong>of</strong> yet another generation.<br />

This process was repeated millions <strong>of</strong> times, until one best<br />

design emerged that wouldn’t improve any further. With<br />

today’s fast computers, millions <strong>of</strong> generations can be<br />

simulated in only a day or so.<br />

The result: an excellent antenna with an odd shape no<br />

human would, or could, design.<br />

Tiny communications<br />

antenna designed by a<br />

computer using artificial<br />

evolution for Space<br />

Technology 5 spacecraft.


Antenna, shown<br />

installed on ST5<br />

spacecraft, uses less<br />

power, gives more<br />

reliable coverage, <strong>and</strong> is<br />

easier to fabricate than<br />

the best antenna<br />

designed by humans for<br />

this spacecraft.<br />

May the Best Face Evolve!<br />

We will see how the computer simulates biological<br />

evolution <strong>and</strong> the laws <strong>of</strong> natural selection in the following<br />

activity. You may be familiar with “smileys,” sometimes<br />

called “emoticons.” These are groupings <strong>of</strong> punctuation<br />

marks on the computer or typewriter to create tiny faces<br />

with smiles, frowns, winks, etc. These are <strong>of</strong>ten used in e-<br />

mail messages to let the reader know the writer is making<br />

a joke or is happy or unhappy about something. In this<br />

activity, we will put punctuation mark “eyes” <strong>and</strong><br />

“mouths” together r<strong>and</strong>omly in an attempt to weed out all<br />

but the best “face” combination for the purpose <strong>of</strong><br />

communicating a certain emotion.<br />

Break the class into groups <strong>of</strong> four players for this activity.<br />

(An additional group <strong>of</strong> one, two, or three will work.)<br />

Create a set <strong>of</strong> eight Image Cards for each group. To<br />

create the Image Cards, photocopy the last page <strong>of</strong> this<br />

article, preferably on light card stock, <strong>and</strong> cut along the<br />

lines. Each card has two lower face halves (mouths) <strong>and</strong><br />

two upper face halves (eyes). Make a photocopy <strong>of</strong> the<br />

<strong>Design</strong> Card shown on the next to last page <strong>of</strong> this article<br />

for each player. In addition, for each group <strong>of</strong> four players,<br />

make three enlarged copies <strong>of</strong> the design card. For Part IV,<br />

an overhead projector, chalk board, or white board would<br />

be useful.<br />

The first step is to set a design objective. As a class,<br />

decide what emotion you wish your final design to<br />

communicate. Choose a feeling or emotion such as<br />

indifference, surprise, joy, sadness, confusion, pain, anger,<br />

boredom, fear, excitement, sleepiness, innocence, guilt,<br />

thoughtfulness, etc.<br />

I. INDIVIDUALLY, EVOLVE A DESIGN WITH TWO<br />

CARDS<br />

1) Each person picks a pair <strong>of</strong> Image Cards.<br />

a) With the Image Cards face down on the table, each<br />

individual in the group picks two Image Cards at<br />

r<strong>and</strong>om to form a two-card set.<br />

2) Use these cards to generate a design.<br />

a) Place one card vertically (“portrait” orientation) on<br />

a tabletop.<br />

b) Place the second card horizontally (“l<strong>and</strong>scape”<br />

orientation) on top <strong>of</strong> the first, aligning the mouth<br />

semicircle on the second card with the eye<br />

semicircle on the first one behind it to form a facial<br />

expression.<br />

c) Note how well the face from this pair matches the<br />

objective emotion.<br />

d) Rotate the “mouth” (top) card to try the other<br />

mouth semicircle with the eye semicircle on the<br />

bottom card.<br />

e) Note how well this face matches the objective<br />

emotion.<br />

3) Evaluate designs <strong>and</strong> select the better fit.<br />

a) In Sector I <strong>of</strong> a <strong>Design</strong> Card, write the eyes number<br />

<strong>and</strong> mouth letter <strong>of</strong> the better match in the boxes<br />

<strong>and</strong> draw the symbols in the face circle.<br />

4) Generate a second design.<br />

a) Reverse the pair <strong>of</strong> Image Cards, placing the<br />

second card vertically (doesn’t matter which<br />

“eyes” are up) <strong>and</strong> the first card horizontally on top<br />

<strong>of</strong> it (doesn’t matter which “mouth” is up). Repeat<br />

Steps 2c – 2e.<br />

5) Evaluate <strong>and</strong> select the better fit.<br />

a) In Sector II <strong>of</strong> the <strong>Design</strong> Card, write the eyes<br />

number <strong>and</strong> mouth letter <strong>of</strong> the better match in the<br />

boxes <strong>and</strong> draw the symbols in the face circle.<br />

6) Select the better design.<br />

a) Compare Faces I <strong>and</strong> II with the objective emotion.<br />

b) Check (√) the small circle next to the better<br />

matching face.<br />

7) Generate new designs.<br />

a) In Sector III, write the eyes number <strong>of</strong> Face I <strong>and</strong><br />

the mouth letter <strong>of</strong> Face II.<br />

b) In Sector IV, write the eyes number <strong>of</strong> Face II <strong>and</strong><br />

the mouth letter <strong>of</strong> Face I.<br />

c) Draw the corresponding faces in each sector.<br />

8) Select the better design.<br />

a) Compare Faces III <strong>and</strong> IV with the objective<br />

emotion.<br />

b) Check (√) the small circle next to the better<br />

matching face.<br />

9) Select the best design from your image card set.<br />

a) Compare the checked faces with the objective<br />

emotion.<br />

b) Add a second check (√√) in the small circle next<br />

to the better matching face.<br />

c) This is the best design that your image card set<br />

has produced.


FEATURE ARTICLE<br />

II. AS A GROUP, GENERATE A NEW, IMPROVED<br />

DESIGN TO BETTER FIT THE OBJECTIVE<br />

1) Evolve a new design from the group’s completed<br />

<strong>Design</strong> Cards.<br />

From the completed <strong>Design</strong> Cards <strong>of</strong> any two players,<br />

one person in the group records both double-checked<br />

designs on one <strong>of</strong> the enlarged <strong>Design</strong> Cards, where all<br />

can see, as follows:<br />

a) In Sector I, write the eyes number <strong>and</strong> the mouth<br />

letter <strong>of</strong> the first double-checked design.<br />

b) In Sector II, write the eyes number <strong>and</strong> the mouth<br />

letter <strong>of</strong> the second double-checked design.<br />

c) Draw the corresponding faces in each sector.<br />

2) Select the better design.<br />

a) Compare Faces I <strong>and</strong> II with the objective emotion.<br />

The whole group can vote on which design is<br />

better.<br />

b) Check (√) the small circle next to the better<br />

matching face.<br />

3) Evolve new designs.<br />

a) In Sector III, write the eyes number <strong>of</strong> Face I <strong>and</strong><br />

the mouth letter <strong>of</strong> Face II.<br />

b) In Sector IV, write the eyes number <strong>of</strong> Face II <strong>and</strong><br />

the mouth letter <strong>of</strong> Face I.<br />

c) Draw the corresponding faces in each sector.<br />

4) Select the better design.<br />

a) The group can compare Faces III <strong>and</strong> IV with the<br />

objective emotion <strong>and</strong> vote on which is better.<br />

b) Check (√) the small circle next to the better<br />

matching face.<br />

5) Select the best design <strong>of</strong> these image card sets.<br />

a) As a group, compare the checked faces with the<br />

objective emotion <strong>and</strong> vote on which is a better<br />

match.<br />

b) Add a second check (√√) in the small circle next to<br />

the better matching face.<br />

c) This is the best design evolved from multiple Image<br />

Card sets.<br />

6) Repeat Part II, Steps 1 through 5 with the two<br />

remaining players in the group. If there is only a<br />

single player remaining, enter only the player’s<br />

double checked selection, draw it, <strong>and</strong> check it.<br />

7) Evolve the group’s optimum match to the design<br />

objective from its card deck.<br />

With the third <strong>Design</strong> Card, summarize the previous<br />

two <strong>Design</strong> Cards in the same way <strong>and</strong>, as a group,<br />

vote to select the optimum design.<br />

III. EVOLVE THE BEST DESIGN FOR THE CLASS<br />

1) The teacher draws a <strong>Design</strong> Card on the board.<br />

2) Evolve the better <strong>of</strong> two groups’ designs.<br />

Using an overhead projector (if available), <strong>and</strong> the final<br />

best <strong>Design</strong> Cards from any two <strong>of</strong> the groups, repeat<br />

Part II to evolve the better design. The whole class can<br />

vote on which designs are better.<br />

3) Evolve the better <strong>of</strong> another two groups’ designs.<br />

Repeat Step 2 with another two groups’ best designs.<br />

4) Evolve the best design.<br />

Continue in this way evolving better designs until all<br />

groups’ designs have been “tested” <strong>and</strong> the single<br />

optimum match to the design objective has been found.<br />

IV. CHOOSE ANOTHER DESIGN OBJECTIVE<br />

Choose another design objective with a different feeling or<br />

emotion <strong>and</strong> you can evolve a totally new <strong>and</strong> different result.<br />

A PROACTIVE APPROACH<br />

TO TECHNOLOGICAL LITERACY<br />

FEATURE ARTICLE<br />

Katherine Weber<br />

“Technological literacy<br />

is vital to individual,<br />

community, <strong>and</strong> national<br />

economic prosperity.”<br />

(ITEA, 1996, p.6)<br />

With the increasing complexity <strong>of</strong><br />

technology, it is important for each<br />

citizen to be able to make informed<br />

decisions about the technology that<br />

he or she uses. This article suggests<br />

that a proactive approach to<br />

advocating technological literacy is<br />

important in changing the greater<br />

public’s misconceptions <strong>of</strong> what it<br />

means to be technologically literate.<br />

The article further suggests several<br />

practical activities that technology<br />

education teachers may use while<br />

advocating technological literacy to<br />

students, parents, administration, <strong>and</strong><br />

the community.<br />

In the public there seems to be<br />

widespread misconception that<br />

being technologically literate<br />

means being able to use<br />

computer or information<br />

technologies pr<strong>of</strong>iciently.<br />

The Public Misconception<br />

In the public there seems to be<br />

widespread misconception that being<br />

technologically literate means being<br />

able to use computer or information<br />

technologies pr<strong>of</strong>iciently (Rose,<br />

Gallup, Dugger, & Starkweather,<br />

2004). If a researcher polled school<br />

districts to explore what technology<br />

means to the administration, one may<br />

interestingly discover that many<br />

responses would include computers,<br />

computer networks, <strong>and</strong> the Internet.<br />

The fact is that many school districts<br />

have spent large amounts <strong>of</strong> money<br />

on implementing or installing<br />

educational technology <strong>and</strong> other<br />

technological devices to assist<br />

teachers in teaching. In many cases,<br />

administrators or teachers outside <strong>of</strong><br />

technology education are deluded<br />

that elaborate, district-wide<br />

technology initiatives that teach<br />

students how to use educational<br />

technology are teaching them about<br />

technology (NAE & NRC, 2002).<br />

The National Academy <strong>of</strong> Engineering<br />

<strong>and</strong> National Research Council joint<br />

report, Technically Speaking, states,<br />

“only one unit in the U.S. Department<br />

<strong>of</strong> Education, the Office <strong>of</strong><br />

Educational Technology, promotes<br />

the use <strong>of</strong> technology as a teaching<br />

tool, but not the teaching <strong>of</strong><br />

technology” (NAE & NRC, p. 58,<br />

2002). One must acknowledge that<br />

computer skills are important to each<br />

citizen who lives in a technological<br />

society, but as illustrated in the<br />

report, technological literacy (TL) is<br />

more complex, encompassing three<br />

interdependent dimensions: (1)<br />

knowledge; (2) ways <strong>of</strong> thinking <strong>and</strong><br />

acting, <strong>and</strong> (3) capabilities. With this<br />

in mind, each technology education<br />

teacher must advocate a holistic<br />

awareness <strong>of</strong> the dimensions <strong>of</strong> TL to<br />

his or her students, fellow faculty,<br />

administration, <strong>and</strong> community.<br />

Being Positive <strong>and</strong> Proactive<br />

In the book, The 7 Habits <strong>of</strong> Highly<br />

Effective People, Stephen Covey<br />

(1989) illustrates what it means to be<br />

proactive. Covey states:<br />

Proactive people focus their<br />

efforts in the Circle <strong>of</strong><br />

Influence. They work on the<br />

things they can do something<br />

about. The nature <strong>of</strong> their<br />

energy is positive, enlarging<br />

<strong>and</strong> magnifying, causing their<br />

Circle <strong>of</strong> Influence to increase<br />

(p. 83).<br />

Although the premise <strong>of</strong> Covey’s<br />

book is personal change, his<br />

description <strong>of</strong> what it means to be<br />

proactive is applicable to educational<br />

initiatives. Many technology<br />

education teachers are frustrated<br />

with the greater public’s<br />

misconception <strong>of</strong> what it means to be<br />

technologically literate. One would<br />

hope that if each technology<br />

education teacher takes Covey’s<br />

proactive approach to heart, focusing<br />

his/her energy on changing the<br />

attitudes <strong>and</strong> perceptions toward TL<br />

within his/her local community, the<br />

collective effort will reshape the<br />

greater public’s underst<strong>and</strong>ing <strong>of</strong> TL<br />

to be more holistic.<br />

The federal No Child Left Behind Act<br />

(NCLBA) is making it even more<br />

dificult for states to distinguish the<br />

broad world <strong>of</strong> technological literacy<br />

Technological Literacy <strong>and</strong> NCLB<br />

Many states are unaware <strong>of</strong> the<br />

differences between educational<br />

technological literacy <strong>and</strong><br />

technological literacy <strong>and</strong> have<br />

initiatives focused entirely on using<br />

computers <strong>and</strong> electronic gadgetry<br />

(Emeagwali, 2004). With the<br />

implementation <strong>of</strong> the NCLB<br />

legislation <strong>and</strong> the reallocation <strong>of</strong><br />

funding, many technology education<br />

teachers are fearful that evolving<br />

dem<strong>and</strong>s placed on the academic<br />

success <strong>of</strong> students, as well as the<br />

uncertainty <strong>of</strong> what constitutes<br />

technological literacy, will negatively<br />

impact technology education<br />

programs. Although this may be true<br />

in some school districts, technology<br />

education teachers can be proactive<br />

by creating innovative ways to<br />

educate individuals about the<br />

complexities <strong>of</strong> technological literacy.<br />

More importantly, teachers can also<br />

be proactive by informing individuals<br />

who are responsible for m<strong>and</strong>ating<br />

NCLB policies that technological<br />

concepts are present in academic<br />

st<strong>and</strong>ards (i.e., mathematics,<br />

science, <strong>and</strong> language arts, as well<br />

as history, <strong>and</strong> geography), which are<br />

<strong>of</strong>ten not found in corresponding<br />

curricula (NAE & NRC, 2002).<br />

Each technology education teacher<br />

should grasp this as an opportunity to<br />

devise creative ways to educate<br />

community members <strong>and</strong><br />

administrators about how these<br />

technological concepts are delivered<br />

effectively in the technology<br />

education classroom. Interestingly, if<br />

successful this also opens a “back<br />

door” for teachers to educate local<br />

administration about the holistic<br />

dimensions <strong>of</strong> TL.<br />

Students as an Alliance for TL<br />

There is no one sure model, method,<br />

or strategy for advocating TL. Each<br />

demographic area has different<br />

educational needs, <strong>and</strong> access to<br />

technology varies. However, every<br />

teacher can start with those they<br />

know best—his/her students. If<br />

students are excited about what they<br />

are learning, they may be a teacher’s<br />

greatest advocates when introducing<br />

the holistic meaning <strong>of</strong> technological<br />

literacy to parents <strong>and</strong> the<br />

community.<br />

Educators can empower students<br />

with what they learn in the<br />

technology education classroom by<br />

involving them in educating parents<br />

<strong>and</strong> the community about TL. For<br />

example,<br />

1. Put students in groups <strong>of</strong> 4-5.<br />

2. On a note card ask students to<br />

write a definition <strong>of</strong> TL.<br />

3. After each student has finished<br />

writing his/her definition, he/she<br />

is to share his/her work with the<br />

others in the group.<br />

4. The students are required to write<br />

a group definition <strong>of</strong> TL.<br />

5. Ask each group to read its<br />

definition.<br />

6. Write the definitions on a piece <strong>of</strong><br />

chart paper.<br />

7. As a class, create a final<br />

definition.<br />

8. Debrief the students by<br />

discussing any <strong>of</strong> the three<br />

dimensions that may have been<br />

overlooked in the definition. The<br />

terminology in the definition<br />

should be relevant to the students<br />

but also include the dimensions <strong>of</strong><br />

knowledge, ways <strong>of</strong> thinking <strong>and</strong><br />

acting, capabilities. 1<br />

After students have grasped the<br />

meaning <strong>of</strong> technological literacy,<br />

introduce reasons why being<br />

technologically literate in the twentyfirst<br />

century is so important. Table 1<br />

outlines potential st<strong>and</strong>ards-based<br />

activities that involve students in<br />

targeting specific audiences (parents,<br />

the community, <strong>and</strong> administration)<br />

in creating TL resources.<br />

Dependent on the level, interests, <strong>and</strong><br />

the technology that is accessible to<br />

the students, other modes <strong>of</strong><br />

communication could be used to<br />

convey the important TL message to<br />

the community. In Table 2, potential<br />

st<strong>and</strong>ards-based electronic<br />

communication activities are outlined.<br />

Many teachers may already be doing<br />

similar activities as those listed in<br />

Tables 1 <strong>and</strong> 2. Creating an alliance<br />

with students is one approach<br />

teachers may use to promote TL, but<br />

there are other successful<br />

approaches teachers across the<br />

discipline have used to market TL. An<br />

excellent venue to share ideas,<br />

materials, <strong>and</strong> resources is through<br />

the <strong>International</strong> Technology<br />

Education Association’s (ITEA)<br />

IdeaGarden listserv. In sharing ideas<br />

at a national level, each teacher can<br />

be proactive in choosing the<br />

suggested materials that would have<br />

the greatest impact on his/her<br />

demographic area.<br />

“ALL persons must be<br />

knowledgeable <strong>of</strong> their<br />

technological environment so<br />

they can participate in<br />

controlling their own destiny”<br />

(ITEA, 1988).<br />

Technological Literacy<br />

<strong>and</strong> the Future<br />

As society is becoming increasingly<br />

dependent on technology, each<br />

citizen must be technologically<br />

literate. St<strong>and</strong>ards for Technological<br />

Literacy (ITEA, 2000/2002) states,<br />

“corporate executives <strong>and</strong> others in<br />

the business world, brokers <strong>and</strong><br />

investment analysts, journalists,<br />

teachers, doctors, nurses, farmers,<br />

<strong>and</strong> homemakers all will be able to<br />

perform their jobs better if they are<br />

technologically literate.” A TEAM<br />

(Together Everyone Achieves More)<br />

effort may reshape the public’s<br />

perception that technological literacy<br />

is important for everyone, even<br />

individuals not pursuing or practicing<br />

a technical craft or career.<br />

MASTERING THE ESSENTIALS FOR A CAREER IN<br />

TECHNOLOGY EDUCATION<br />

FEATURE ARTICLE<br />

Harry T. Roman<br />

Prologue<br />

In this article, I shall endeavor to set<br />

an ideal, a personal wish list if you<br />

will, for what I believe are the key<br />

areas <strong>of</strong> competency young<br />

technology education teachers should<br />

be developing while still in college.<br />

Not being an educator in the<br />

traditional sense, I write from the<br />

perspective <strong>of</strong> an engineer <strong>and</strong><br />

inventor who has spent considerable<br />

time interacting with the educational<br />

community. In this paper, I pr<strong>of</strong>ess<br />

by default to be a member <strong>of</strong> “the<br />

tech ed school <strong>of</strong> hard knocks” <strong>and</strong> a<br />

long-time devotee <strong>of</strong> tech ed<br />

principles <strong>and</strong> practices.<br />

I hope you find my thoughts both<br />

relevant <strong>and</strong> challenging, appreciating<br />

the perspective from which they<br />

originate.<br />

The Wish List<br />

There is no priority or preference<br />

inherent in this listing <strong>of</strong> preferred<br />

competencies. They are the<br />

requisites I have personally compiled<br />

over the years based on my<br />

experiences. I have tried to group<br />

them for convenience.<br />

Some Basics for Action:<br />

Definitions <strong>and</strong> Distinctions<br />

Being able to clearly draw<br />

distinctions between the definitions<br />

<strong>of</strong> science, technology, <strong>and</strong><br />

engineering would be ideal. Our<br />

society <strong>of</strong>ten blurs the lines between<br />

these important terms. Tech ed<br />

teachers should see clearly the<br />

distinctions. Science is about<br />

discovery, while engineering is about<br />

application in the real world.<br />

Technology is the know-how to make<br />

what we want from what we have<br />

(resources) <strong>and</strong> is the main creative<br />

Over 60% <strong>of</strong> the annual growth in our<br />

nation’s economy is directly attributable to<br />

scientific <strong>and</strong> technological advances.<br />

tool <strong>of</strong> the engineer. Engineering <strong>and</strong><br />

tech ed share much common<br />

ground—the human designed<br />

world—achieved in a benign,<br />

beneficial, <strong>and</strong> cost-effective manner.<br />

Most definitely, the links to<br />

engineering must be brought into the<br />

tech ed classroom.<br />

Because <strong>of</strong> the close relationship that<br />

tech ed has with engineering, wouldbe<br />

tech ed teachers should have<br />

some form <strong>of</strong> interaction with<br />

working engineers as well as a<br />

sense <strong>of</strong> their pr<strong>of</strong>ession <strong>and</strong> the<br />

problem-solving regimen used by<br />

engineers in their daily work. A study<br />

<strong>of</strong> the history <strong>of</strong> engineering <strong>and</strong> its<br />

roots in ancient times would be <strong>of</strong><br />

significant value. Most, if not all, <strong>of</strong><br />

the seven wonders <strong>of</strong> the ancient<br />

world were largely engineering feats.<br />

Students should be familiar with<br />

great engineers <strong>of</strong> the world <strong>and</strong><br />

their contributions. The first man on<br />

the moon was an aeronautical<br />

engineer! Five U.S. presidents were<br />

engineers (can you name them?). It is<br />

highly likely that a good portion <strong>of</strong> the<br />

students that tomorrow’s tech ed<br />

teachers influence will become<br />

engineers, <strong>and</strong> best that engineering<br />

be discussed at the K-12 level.<br />

It is also imperative that tech ed<br />

teachers fully underst<strong>and</strong> that<br />

technology long preceded science.<br />

There are thous<strong>and</strong>s <strong>of</strong> years <strong>of</strong><br />

successful tool-making behind such a<br />

premise; but formal science as we<br />

recognize it today is a mere 500<br />

years old. Technology is the mortar<br />

between the bricks <strong>of</strong> science, the<br />

empirical glue that holds the<br />

structure together.<br />

Good Communications<br />

The basis <strong>of</strong> all academic, <strong>and</strong><br />

eventually corporate performance, is<br />

good communication. This bedrock<br />

skill set comes in both oral <strong>and</strong> written<br />

form <strong>and</strong> should span the gamut from<br />

short thematic writing to a fully<br />

researched project paper complete<br />

with formal footnotes, references, <strong>and</strong><br />

bibliography, to the development <strong>and</strong><br />

presentation <strong>of</strong> original work via formal<br />

slide formats followed by Q&A. Ideally,<br />

I would also recommend that tech ed<br />

career aspirants be able to respond to<br />

extemporaneous speaking challenges<br />

too. A powerful way to drive this<br />

message home to would-be tech ed<br />

teachers is to grade their work twice,<br />

once for its “technical” rigor <strong>and</strong> once<br />

for its “communications clarity.” That<br />

would do the trick <strong>of</strong> reinforcing the<br />

importance <strong>of</strong> good communications.<br />

All tech ed teachers should have<br />

numerous opportunities during their<br />

undergraduate experience to<br />

participate in <strong>and</strong> lead team problemsolving<br />

exercises. It is important to<br />

gain extensive experience with how<br />

this powerful educational tool should<br />

be used in the classroom. In my<br />

observations, this technique is what<br />

sets apart the tech ed experience from<br />

activities in which other teachers<br />

partake, <strong>and</strong> it is the fundamental<br />

reason why tech ed is successful in<br />

integrating the curricula.<br />

The Value <strong>of</strong> Mathematics<br />

It is not sufficient to be good at math.<br />

Tech ed teachers must be able to<br />

apply it, respecting it as another tool<br />

that helps them underst<strong>and</strong>, quantify,<br />

<strong>and</strong> bound the world for their students.<br />

The ability to estimate, ballpark, <strong>and</strong><br />

use mathematics to place designs<br />

<strong>and</strong> potential solutions in perspective<br />

is paramount for a tech ed teaching<br />

career. Our globally competitive<br />

world runs on mathematics as it does<br />

on fuel. Tech ed teachers, regardless<br />

<strong>of</strong> the grade levels at which they will<br />

ultimately be teaching, should be able<br />

to appreciate the value <strong>of</strong><br />

mathematics <strong>and</strong> articulate its<br />

importance in classroom activities<br />

<strong>and</strong> design challenges. They should<br />

be comfortable manipulating<br />

mathematics symbols, able to draw<br />

conclusions from its application, <strong>and</strong><br />

trusting <strong>of</strong> the directions it indicates<br />

in their designs. It should become<br />

second nature to tech ed teachers to<br />

reach out for the mathematics tool.<br />

A Physical Feel <strong>of</strong> the World<br />

Computers are simply knowledge<br />

amplifiers, devoid <strong>of</strong> any creativity or<br />

insight save that imbued them by<br />

their programmers. A good tech ed<br />

teacher has sufficient grounding in<br />

first principles to be able to have an<br />

intuitive feel for the “rightness” <strong>of</strong><br />

solutions, whether computer-derived<br />

or otherwise. This comes with<br />

frequent exposure to problem-solving<br />

regimens, confidence honed through<br />

success <strong>and</strong> constructive criticism,<br />

<strong>and</strong> a frank analysis <strong>of</strong> design failure.<br />

Computers are tools, not arbiters <strong>of</strong><br />

“rightness”—<strong>and</strong> they most certainly<br />

should not be the image that springs<br />

to mind when someone says the<br />

word “technology.” Their output is to<br />

be as critically reviewed <strong>and</strong> weighed<br />

as any other data/information.<br />

As a minimum, would-be tech ed<br />

teachers should be able to explain<br />

<strong>and</strong> demonstrate with mathematics:<br />

• Simple machines <strong>and</strong> their<br />

ubiquitous presence in real life.<br />

• The force over distance action.<br />

• Hydraulics (Pascal’s principle).<br />

• How transformers work.<br />

• AC versus DC current.<br />

• The difference between power <strong>and</strong><br />

energy.<br />

• Simple airplane flight, <strong>and</strong> fluid<br />

flow (Bernoulli’s principle).<br />

Brain-Based Research<br />

In light <strong>of</strong> the remarkable findings in<br />

the area <strong>of</strong> brain-based research, the<br />

tech ed teacher <strong>of</strong> tomorrow should<br />

be knowledgeable <strong>and</strong> versed in the<br />

classroom implications <strong>of</strong> this work,<br />

specifically the ability to:<br />

• Apply head <strong>and</strong> h<strong>and</strong>s learning<br />

paradigms as needed.<br />

• Assemble balanced classroom<br />

student teams for design<br />

challenges.<br />

• Teach in a Socratic style,<br />

coalescing answers to classroom<br />

challenges.<br />

• Conduct open-ended, team-based<br />

exercises.<br />

• Teach solution methods to multidimensional<br />

problems in a multidisciplinary<br />

manner.<br />

Technology <strong>and</strong> Our National<br />

Culture <strong>and</strong> History:<br />

Underst<strong>and</strong>ing Our Nation’s<br />

Technological History<br />

We did not attain the status <strong>of</strong> most<br />

technological nation on the planet by<br />

accident. There is a rich history with<br />

1800-1850: Canals, steam power,<br />

textile manufacturing.<br />

1850-1900: Railroads, steel, the<br />

emergence <strong>of</strong> natural gas, water,<br />

telephone, sewage, <strong>and</strong> electric<br />

utilities.<br />

1900-1950: Electric power,<br />

automobiles, hydropower, chemicals,<br />

mass media, communications, <strong>and</strong><br />

R&D labs.<br />

1950-2000: Computers, electronics,<br />

aerospace, pharmaceuticals, nuclear<br />

power, a national highway system,<br />

TV <strong>and</strong> biotechnology.<br />

A tech ed teacher should have a good<br />

grasp <strong>of</strong> what those defining phases<br />

were <strong>and</strong> how they influenced our<br />

society.<br />

The Technology-History-Economy<br />

Triad<br />

Because we live in a free market<br />

economy <strong>and</strong> expect pr<strong>of</strong>it for our<br />

hard work <strong>and</strong> ingenuity, this has<br />

made all the difference in both our<br />

technological creativity <strong>and</strong> optimism<br />

for the future. Our technology,<br />

history, <strong>and</strong> economy are inextricably<br />

intertwined. Any attempt to separate<br />

them will detrimentally alter our<br />

world-recognized penchant for<br />

ingenuity <strong>and</strong> out-<strong>of</strong>-the-box thinking.<br />

Capitalism <strong>and</strong> its ability to influence<br />

creativity, markets, <strong>and</strong><br />

entrepreneurship was built into our<br />

national Constitution from the very<br />

beginning—the very fuel a fledgling<br />

new nation would need to tame its<br />

frontiers. Over 60% <strong>of</strong> the annual<br />

growth in our nation’s economy is<br />

directly attributable to scientific <strong>and</strong><br />

technological advances. It is the very<br />

essence <strong>of</strong> our high st<strong>and</strong>ard <strong>of</strong><br />

living. To effectively discuss the<br />

benefits <strong>of</strong> technology, a tech ed<br />

teacher must recognize the<br />

importance <strong>of</strong> the technology-historyeconomy<br />

triad.<br />

The Value <strong>of</strong> Infrastructure<br />

Every day, vital services are delivered<br />

to our homes, making it unnecessary<br />

for us to arrange for the availability <strong>of</strong><br />

these resources or expend personal<br />

time <strong>and</strong> energy to gather or attain<br />

them. I am speaking <strong>of</strong> the<br />

infrastructure/services such as water,<br />

electricity, telephone, natural gas,<br />

sewerage, cable, <strong>and</strong> satellite TV. In<br />

the last few years, there have been<br />

major changes to the telephone <strong>and</strong><br />

electricity infrastructure (cell phones,<br />

home PC use, deregulation <strong>of</strong><br />

electricity, distributed generation<br />

sources, etc.). New technological<br />

advances have totally re-shaped<br />

these infrastructures. What a fertile<br />

area for study <strong>and</strong> what it portends<br />

for the future! Students <strong>of</strong>ten take<br />

these infrastructures for granted, <strong>and</strong><br />

should be studying the origin, history,<br />

use, <strong>and</strong> growth <strong>of</strong> these essential<br />

community-based services.<br />

Competent tech ed teachers should<br />

be able to bring the value <strong>of</strong> these<br />

services to their classrooms <strong>and</strong><br />

arrange for students to creatively<br />

explore <strong>and</strong> underst<strong>and</strong> them.<br />

Technology, Ecology, <strong>and</strong> Man<br />

The internalization <strong>of</strong> environmental<br />

costs <strong>and</strong> impacts on the way<br />

business is conducted has been a<br />

significant achievement over the last<br />

40 years. All major projects are<br />

required to divulge the potential<br />

environmental impacts <strong>of</strong> their<br />

execution. Inherent in this paradigm<br />

are powerful learning activities that<br />

the modern tech ed teacher should<br />

be capable <strong>of</strong> articulating in the<br />

classroom. Students should be<br />

challenged to evaluate <strong>and</strong> debate<br />

the environmental pros <strong>and</strong> cons <strong>of</strong> a<br />

variety <strong>of</strong> technologies. Here are<br />

some representative technologies a<br />

tech ed teacher should be well<br />

versed in <strong>and</strong> prepared to discuss<br />

<strong>and</strong> stimulate debate around:<br />

• Trains <strong>and</strong> rail transportation<br />

• The automobile<br />

• Electric power generation<br />

• Biotechnology<br />

• Micro miniaturization <strong>of</strong><br />

electronics/nanotechnology<br />

• Nuclear power<br />

• Solar energy<br />

Invention <strong>and</strong> Innovation: The<br />

Innovation Process<br />

The creation <strong>of</strong> new products <strong>and</strong><br />

services should be viewed <strong>and</strong><br />

respected for the multi-dimensional<br />

challenge <strong>and</strong> multi-disciplinary<br />

solution process that it is. I know <strong>of</strong><br />

no better way to naturally integrate<br />

the curricula than to have students<br />

engage in frequent, open-ended<br />

design challenges. Tech ed teachers<br />

should grasp that:<br />

• Innovation equals invention +<br />

market thrust.<br />

• Technical <strong>and</strong> non-technical<br />

aspects <strong>of</strong> a problem must be<br />

resolved <strong>and</strong> blended.<br />

• High quality questions tend to yield<br />

high quality, <strong>and</strong> more robust,<br />

solutions.<br />

• Planning a new product is as<br />

important as attempting to execute<br />

implementation.<br />

• Innovation is inherently an iterative<br />

activity.<br />

• An arsenal <strong>of</strong> creativity techniques<br />

can be used to generate possible<br />

solutions.<br />

• Out-<strong>of</strong>-the-box thinking is always in<br />

vogue.<br />

• The unique perspective <strong>of</strong>ten wins<br />

in the marketplace.<br />

• Innovation is a high-risk process,<br />

<strong>and</strong> failure is common.<br />

Intellectual Property<br />

In the globally competitive<br />

marketplace, what a company knows<br />

is as important as what it owns.<br />

Aspiring tech ed teachers should:<br />

• Know what patents are.<br />

• Be familiar with how inventors<br />

keep log books.<br />

• Have been involved in invention<br />

challenges in both team <strong>and</strong><br />

individual settings.<br />

• Know how to search patents on<br />

the Internet.<br />

• Be able identify both past <strong>and</strong><br />

current inventors <strong>and</strong> what they<br />

have accomplished.<br />

• Be aware <strong>of</strong> the economic value <strong>of</strong><br />

patents.<br />

Invention<br />

A tech ed teacher should be prepared<br />

to use the invention experience as a<br />

true curriculum integrator. Requests<br />

for invention related in-class talks<br />

<strong>and</strong> teacher in-service seminars has<br />

kept me busy for the last five years.<br />

It is a highly popular topic as it<br />

engages the head <strong>and</strong> h<strong>and</strong>s <strong>of</strong> the<br />

students <strong>and</strong> allows them to<br />

participate in open-ended, teambased,<br />

exercises. Aspiring tech ed<br />

teachers should:<br />

• Underst<strong>and</strong> how marketplace<br />

wishes for new products <strong>and</strong><br />

services jump-start the invention<br />

process.<br />

• Conduct exercises in class<br />

whereby student inventors learn<br />

how to compile their thinking in an<br />

inventor’s log book.<br />

• Appreciate how, along with the<br />

invention logbook, inventors<br />

compile their strategies about how<br />

to market their inventions.<br />

• How selecting <strong>and</strong> staffing the<br />

invention team is as important as<br />

creating the invention (here the<br />

teacher should be able to mix head<br />

<strong>and</strong> h<strong>and</strong> learners for maximum<br />

effect).<br />

• Be able to freely identify <strong>and</strong><br />

discuss famous U.S. inventors <strong>and</strong><br />

their accomplishments.<br />

• Document the growth <strong>of</strong> various<br />

technologies that have had a major<br />

influence on American life (light<br />

bulb, electronic circuit<br />

miniaturization, personal<br />

computer...etc.).<br />

• Use timelines to show how various<br />

inventions influenced each other<br />

<strong>and</strong> other segments <strong>of</strong> society.<br />

Technical Career Considerations<br />

Skill Sets For Success<br />

There are definable skill sets for<br />

success in the twenty-first century<br />

workplace. Most <strong>of</strong> them are directly<br />

related to the seismic shift away<br />

from a machine to an information<br />

economy, one where great value is<br />

placed upon higher-order thinking<br />

skills. A competent tech ed teacher<br />

should be able to take the key skills<br />

listed below <strong>and</strong> relate them back to<br />

work being done in the classroom on<br />

a daily basis:<br />

• The ability to connect <strong>and</strong><br />

interrelate subject matter<br />

• Good oral <strong>and</strong> written<br />

communication skills<br />

• Logical <strong>and</strong> intuitive analytical<br />

skills<br />

• Planning <strong>and</strong> organization skills<br />

• Interpersonal <strong>and</strong> team player skills<br />

• Being able to turn ideas into reality<br />

<strong>and</strong> to manage that process<br />

• Underst<strong>and</strong>ing markets <strong>and</strong> what<br />

customers want<br />

• The capability to learn <strong>and</strong> re-learn<br />

effectively <strong>and</strong> efficiently<br />

The Benefits <strong>of</strong> a Technical<br />

Career<br />

Tech ed students, like all others,<br />

require career guidance. The tech ed<br />

teacher should be able to articulate<br />

the benefits <strong>of</strong> a technical career <strong>and</strong><br />

relate them back to classroom<br />

activities. Specifically, the tech ed<br />

teacher should be able to discuss<br />

how a technical career path:<br />

• Relates to other careers.<br />

• Influences starting <strong>and</strong> long-term<br />

average salaries.<br />

• Requires life-long learning.<br />

The tech ed teacher should also be<br />

able to present:<br />

• Examples <strong>of</strong> well-known Americans<br />

who have pursued technical<br />

careers.<br />

Epilogue<br />

Here then is my wish list for tech ed<br />

teacher success. It is based upon 35<br />

years <strong>of</strong> industrial research <strong>and</strong><br />

engineering experience, combined<br />

with numerous interactions with K-12<br />

teachers <strong>and</strong> students, <strong>and</strong> the<br />

teaching <strong>of</strong> graduate engineering<br />

courses at the New Jersey Institute<br />

<strong>of</strong> Technology—my alma mater. It<br />

also reflects my long-time association<br />

with the Technology Educators<br />

Association <strong>of</strong> New Jersey (TEANJ)<br />

<strong>and</strong> my good friends <strong>and</strong> colleagues<br />

at The College <strong>of</strong> New Jersey. Of<br />

late, my published freelance<br />

educational papers <strong>and</strong> articles have<br />

exerted a powerful influence on my<br />

opinions, as has my chairmanship <strong>of</strong><br />
