ABSTRACT The authors conducted design or classroom<br />
experiments (R. Gersten, S. Baker, & J. W. Lloyd, 2000) at<br />
2 sites (Pennsylvania and Florida) to test the effectiveness of<br />
schema-based <strong>in</strong>struction (SBI) prior to conduct<strong>in</strong>g formal<br />
experimental studies. Results of Study 1 conducted <strong>in</strong> 2 3rdgrade,<br />
low-ability classrooms and 1 special education classroom<br />
<strong>in</strong>dicated mean score improvements from pretest to<br />
posttest on word problem solv<strong>in</strong>g and computation fluency<br />
measures. In addition, student perceptions of SBI accord<strong>in</strong>g to<br />
a strategy satisfaction questionnaire revealed SBI as effective<br />
<strong>in</strong> help<strong>in</strong>g solve word problems. Results of Study 2, which<br />
<strong>in</strong>cluded a heterogeneous (high-, average-, and low-achiev<strong>in</strong>g)<br />
sample of 3rd graders, also revealed student improvement on<br />
the word problem solv<strong>in</strong>g and computation fluency measures.<br />
However, the outcomes were not as positive <strong>in</strong> Study 2 as <strong>in</strong><br />
Study 1. Lessons learned from the 2 studies are discussed<br />
with regard to teach<strong>in</strong>g and learn<strong>in</strong>g mathematical word problem<br />
solv<strong>in</strong>g for different groups of students.<br />
Keywords: elementary grade students, mathematics <strong>in</strong>struction,<br />

Current education reforms support challeng<strong>in</strong>g<br />
learn<strong>in</strong>g standards and school accountability. In<br />
mathematics education, the emphasis is on the<br />
development of conceptual understand<strong>in</strong>g and reason<strong>in</strong>g<br />
over memorization and rote learn<strong>in</strong>g (Goldsmith & Mark,<br />
1999; Hiebert et al., 1996; National Research Council,<br />
2001). <strong>Mathematical</strong> problem solv<strong>in</strong>g is a central theme <strong>in</strong><br />
the Pr<strong>in</strong>ciples and Standards for School Mathematics (National<br />
Council of Teachers of Mathematics [NCTM], 2000).<br />
Although the current emphasis is on solv<strong>in</strong>g complex<br />
authentic problems situated <strong>in</strong> everyday contexts, story<br />
problems that range from simple to complex represent “the<br />
most common form of problem-solv<strong>in</strong>g” assignment <strong>in</strong><br />
school mathematics curricula (Jonassen, 2003, p. 267).<br />
Story problems pose difficulties for many elementary<br />
students because of the complexity of the solution process<br />
(Jonassen, 2003; Lucangeli, Tressoldi, & Cendron, 1998;<br />
Schurter, 2002). Mathematics tasks that <strong>in</strong>volve storycontext<br />
problems are much more challeng<strong>in</strong>g than are nocontext<br />
problems (Cumm<strong>in</strong>s, K<strong>in</strong>tsch, Reusser, &<br />
283<br />
Weimer, 1988; Mayer, Lewis, & Hegarty, 1992; Nathan,<br />
Long, & Alibali, 2002). Although children may know<br />
procedures for solv<strong>in</strong>g no-context problems, solv<strong>in</strong>g story<br />
problems requires them to <strong>in</strong>tegrate several cognitive<br />
processes that are difficult for children with an <strong>in</strong>sufficient<br />
knowledge base or limited work<strong>in</strong>g memory capacity.<br />
When solv<strong>in</strong>g story problems, for example, children<br />
need to (a) understand the language and factual <strong>in</strong>formation<br />
<strong>in</strong> the problem, (b) translate the problem with relevant<br />
<strong>in</strong>formation to create an adequate mental representation,<br />
(c) devise and monitor a solution plan, and (d)<br />
execute adequate procedural calculations (Desoete, Roeyers,<br />
& De Clercq, 2003; Mayer, 1999). In short, solv<strong>in</strong>g<br />
word problems relates closely to comprehension of the<br />
relations and goals with<strong>in</strong> the problem (e.g., Briars &<br />
Lark<strong>in</strong>, 1984; Cumm<strong>in</strong>s et al.; De Corte, Verschaffel, &<br />
De W<strong>in</strong>, 1985; K<strong>in</strong>tsch & Greeno, 1985; Riley, Greeno,<br />
& Heller, 1983).<br />
Story problems are critical for help<strong>in</strong>g children connect<br />
different mean<strong>in</strong>gs, <strong>in</strong>terpretations, and relationships to<br />
mathematics operations (Van de Walle, 2004). How then<br />
do educators enhance students’ mathematical word problem-solv<strong>in</strong>g<br />
skill Traditional textbook problem-solv<strong>in</strong>g<br />
<strong>in</strong>struction has not effectively improved the learn<strong>in</strong>g of students<br />
at risk for mathematics difficulties. Many mathematics<br />
textbooks are organized so that the same procedure<br />
(e.g., subtraction) is used to solve all problems on a page.<br />
As a result, students do not have the opportunity to discrim<strong>in</strong>ate<br />
among problems that require different solution<br />
strategies. Furthermore, traditional <strong>in</strong>struction teaches students<br />
to use keywords (e.g., <strong>in</strong> all suggests addition, left suggests<br />
subtraction, share suggests division; Lester, Garofalo,<br />
& Kroll, 1989, p. 84) that are limit<strong>in</strong>g. Accord<strong>in</strong>g to Van<br />
de Walle, “Key words are mislead<strong>in</strong>g,” “Many problems do<br />
not have key words,” and “Key words send a terribly wrong<br />
message about do<strong>in</strong>g math” (p. 152). Thus, this approach<br />

ignores the mean<strong>in</strong>g and structure of the problem and fails<br />
to develop reason<strong>in</strong>g and mak<strong>in</strong>g sense of problem situations<br />
(Van de Walle).<br />
In contrast, current mathematics reform efforts advocate<br />
that teachers act as facilitators to help students construct<br />
their own understand<strong>in</strong>gs of mathematical concepts and<br />
relationships (e.g., develop<strong>in</strong>g the abilities of <strong>in</strong>quiry, problem<br />
solv<strong>in</strong>g, and mathematics connections). However, the<br />
literature is <strong>in</strong>conclusive about the benefits of that approach<br />
for all learners (Baxter, Woodward, Voorhies, & Wong,<br />
2002). As the range of skills that students br<strong>in</strong>g to the classroom<br />
<strong>in</strong>creases, the challenge for teachers is synthesiz<strong>in</strong>g<br />
knowledge regard<strong>in</strong>g mathematics content and processes,<br />
student learn<strong>in</strong>g, effective <strong>in</strong>struction models, and appropriate<br />
classroom opportunities and experiences (Ma, 1999).<br />
Learners who lack sufficient prior knowledge may need more<br />
supportive <strong>in</strong>structional strategies <strong>in</strong> which the teacher scaffolds<br />
<strong>in</strong>formation process<strong>in</strong>g by supply<strong>in</strong>g a greater degree of<br />
<strong>in</strong>structional facilitation dur<strong>in</strong>g the learn<strong>in</strong>g process.<br />
To promote elementary students’ mathematical problemsolv<strong>in</strong>g<br />
skills, we relied on models for understand<strong>in</strong>g and<br />
assess<strong>in</strong>g children’s solutions for addition and subtraction<br />
word problems derived from schema theories of cognitive<br />
psychology (Briars & Lark<strong>in</strong>, 1984; Carpenter & Moser,<br />
1984; K<strong>in</strong>tsch & Greeno, 1985; Riley, Greeno, & Heller,<br />
1983). On the basis of those models, we designed an <strong>in</strong>tervention<br />
(i.e., schema-based <strong>in</strong>struction [SBI]) for students<br />
with high-<strong>in</strong>cidence disabilities and for those at risk for<br />
failure <strong>in</strong> mathematics (e.g., Jitendra et al., 1998; Jitendra,<br />
Hoff, & Beck, 1999). Contrary to earlier <strong>in</strong>vestigations of<br />
SBI that provided <strong>in</strong>dividual or small-group <strong>in</strong>struction by<br />
researchers <strong>in</strong> rooms adjacent to the students’ classrooms,<br />
we deemed it critical to broaden the learn<strong>in</strong>g environment<br />
to a typical classroom context where<strong>in</strong> the classroom<br />
teacher provided all <strong>in</strong>struction. In addition, we added selfmonitor<strong>in</strong>g<br />
to strategy use because teach<strong>in</strong>g students to<br />
self-regulate their learn<strong>in</strong>g has an added positive effect on<br />
their mathematics problem-solv<strong>in</strong>g performance (L. S.<br />
Fuchs et al., 2003; Schunk, 1998; Verschaffel et al., 1999).<br />
Theoretical Framework<br />
Results of a number of research studies on solv<strong>in</strong>g addition<br />
and subtraction word problems have shown that<br />
semantic or mathematical structure of problems (i.e., specific<br />
characteristics of the problem and the semantic relationships<br />
among the various problem features) is much more<br />
relevant than is syntax (i.e., how a problem is worded; Carpenter,<br />
Hiebert & Moser, 1983; Carpenter & Moser, 1984).<br />
Notwithstand<strong>in</strong>g the ease or difficulty of the syntactic<br />
structure of problems, students who lack a well-developed<br />
semantic structure use a “bottom-up or text-driven<br />
approach to comprehend a problem statement” (Kameenui<br />
& Griff<strong>in</strong>, 1989, p. 581). Given the critical role of semantic<br />
structure <strong>in</strong> problem solution, Carpenter and Moser postulated<br />
a classification of addition and subtraction wordproblem<br />
types that <strong>in</strong>clude change, comb<strong>in</strong>e, compare, and<br />
equalize. Of those problem types, change, comb<strong>in</strong>e, and compare<br />
problems are characteristic of most addition and subtraction<br />
word problems presented <strong>in</strong> elementary mathematics<br />
textbooks, <strong>in</strong>dicat<strong>in</strong>g the need for research focus<strong>in</strong>g<br />
on these problem types. Table 1 shows the three different<br />
problem types and their characteristics. Change problems<br />
usually beg<strong>in</strong> with an <strong>in</strong>itial quantity and a direct or<br />
implied action that causes either an <strong>in</strong>crease or decrease <strong>in</strong><br />
that quantity. The three sets of <strong>in</strong>formation <strong>in</strong> a change<br />
problem are the beg<strong>in</strong>n<strong>in</strong>g, change, and end<strong>in</strong>g. In the<br />
change situation, the object identities (e.g., video games)<br />
for beg<strong>in</strong>n<strong>in</strong>g, change, and end<strong>in</strong>g are the same (see Figure<br />
1). In contrast, comb<strong>in</strong>e or group problems <strong>in</strong>volve two dist<strong>in</strong>ct<br />
groups or subsets that comb<strong>in</strong>e to form a new group or<br />
set. Group problems require an understand<strong>in</strong>g of part-partwhole<br />
relations. The relation between a particular set and<br />
its two dist<strong>in</strong>ct subsets is static (i.e., no action is implied).<br />
Compare problems <strong>in</strong>volve the comparison of two disjo<strong>in</strong>t<br />
sets (compared and referent); the emphasis is on the static<br />
relation between the two sets (see Table 1). The three sets<br />
of <strong>in</strong>formation <strong>in</strong> a compare problem are the compared, referent,<br />
and difference. For each problem type, there are<br />
three items of <strong>in</strong>formation; the position of the unknown <strong>in</strong><br />
these problems may be any one of the three items, which<br />
can be found if the other two items are given.<br />
Also critical to successful mathematics problem solv<strong>in</strong>g<br />
is doma<strong>in</strong>-specific knowledge (conceptual and procedural;<br />
e.g., Hegarty, Mayer, & Monk, 1995). An important aspect<br />
of doma<strong>in</strong>-specific concept knowledge is problem comprehension/representation,<br />
which <strong>in</strong>volves translat<strong>in</strong>g the<br />
text of the problem <strong>in</strong>to a semantic representation on the<br />

basis of an understand<strong>in</strong>g of the problem structure.<br />
Although procedural knowledge (e.g., know<strong>in</strong>g the series of<br />
sequential steps used to solve rout<strong>in</strong>e mathematical tasks,<br />
such as add<strong>in</strong>g 27 + 19 as well as know<strong>in</strong>g mathematical<br />
symbolism, such as +, =, and >) is also important, it “is<br />
extremely limited unless it is connected to a conceptual<br />
knowledge base” (Prawat, 1989, p. 10). In fact, a lack of<br />
understand<strong>in</strong>g of the problem situation may result <strong>in</strong> a solu-

tion plan that is immaturely developed. Successful problem<br />
solvers can translate and <strong>in</strong>tegrate <strong>in</strong>formation <strong>in</strong> the problem<br />
<strong>in</strong>to a coherent mental representation that mediates<br />
problem solution (Mayer, 1999; Mayer & Hegarty, 1996).<br />
However, many students have difficulty with problem comprehension<br />
and solution and would benefit from <strong>in</strong>struction<br />
<strong>in</strong> construct<strong>in</strong>g a model to represent the situation <strong>in</strong><br />
the text, followed by solution plann<strong>in</strong>g based on the model<br />
(Hegarty et al., 1995). Evidently, schema-based <strong>in</strong>struction<br />
(SBI), with its emphasis on semantic structure and problem<br />
representation, is one solution to advanc<strong>in</strong>g students’<br />
mathematical problem-solv<strong>in</strong>g skills.<br />
The goal of SBI is to help students establish and expand<br />
on the doma<strong>in</strong> knowledge <strong>in</strong> which schemata are the central<br />
focus. A schema is a general description of a group of<br />
problems that share a common underly<strong>in</strong>g structure requir<strong>in</strong>g<br />
similar solutions (Chen, 1999; Gick & Holyoak, 1983).<br />
Accord<strong>in</strong>g to Marshall (1995), schemata “capture both the<br />
patterns of relationships as well as their l<strong>in</strong>kages to operations”<br />
(Marshall, 1995, p. 67). SBI analyzes explicitly the<br />
problem schema (e.g., the part-part whole) and the l<strong>in</strong>ks<br />
perta<strong>in</strong><strong>in</strong>g to how different elements of the schema are<br />
related (e.g., parts make up the whole). Understand<strong>in</strong>g<br />
these l<strong>in</strong>ks is crucial <strong>in</strong> select<strong>in</strong>g appropriate operations<br />
needed for problem solution. For example, if the whole <strong>in</strong><br />
the problem is unknown, add<strong>in</strong>g the parts is necessary to<br />
solve for the whole; if one of the parts is unknown, subtract<strong>in</strong>g<br />
the part(s) from the whole is needed to solve for<br />
the unknown part. An important difference between SBI<br />
and other <strong>in</strong>structional approaches is that only SBI emphasizes<br />
<strong>in</strong>tegrat<strong>in</strong>g the various pieces of factual <strong>in</strong>formation<br />
essential for problem solv<strong>in</strong>g. Although factual details are<br />
important, they should not be the central focus of <strong>in</strong>struction<br />
and learn<strong>in</strong>g. In short, SBI allows students to approach<br />
the problem by focus<strong>in</strong>g on the underly<strong>in</strong>g problem structure,<br />
thus facilitat<strong>in</strong>g conceptual understand<strong>in</strong>g and adequate<br />
word-problem-solv<strong>in</strong>g skills (Marshall).<br />
Purpose<br />
We conducted design or classroom experiments concurrently<br />
at two different geographical sites. Our research team<br />
collaborated with teachers to conduct a series of word problem<br />
solv<strong>in</strong>g teach<strong>in</strong>g sessions us<strong>in</strong>g SBI with a small sample<br />
of students to understand what works, prior to conduct<strong>in</strong>g a<br />
formal experiment (Cobb, Confrey, diSessa, Lehrer, &<br />
Schauble, 2003). Design experiments <strong>in</strong>volve <strong>in</strong>-depth<br />
study of an <strong>in</strong>novation <strong>in</strong> a small scale to understand not<br />
only how responsive an <strong>in</strong>tervention is to the dynamics of<br />
the classroom but also to understand “the nature of effective<br />
adaptations for students with disabilities” (Gersten et al.,<br />
2000, p. 29). Specifically, a design experiment is aimed at<br />
improv<strong>in</strong>g the connections between teach<strong>in</strong>g and learn<strong>in</strong>g<br />
through the process of cont<strong>in</strong>uous cycles of “design, enactment,<br />
analysis, and redesign” of lessons <strong>in</strong> authentic classrooms<br />
(Cobb et al., 2003; The Design-Based Research Collective,<br />
2003). Researchers use the processes of iteration<br />
and feedback loops to empirically ref<strong>in</strong>e the <strong>in</strong>novation<br />
(e.g., curriculum product, tasks, scaffolds) and design an<br />
effective and efficient <strong>in</strong>tervention for use <strong>in</strong> experimental<br />
or quasi-experimental studies (Gersten et al., 2000).<br />
The learn<strong>in</strong>g environment <strong>in</strong> our design experiments<br />
<strong>in</strong>cluded a typical classroom context rather than an exceptional<br />
<strong>in</strong>structional sett<strong>in</strong>g (i.e., special rooms outside the<br />
regular classroom), where<strong>in</strong> the teacher conducted all<br />
<strong>in</strong>struction. The purposes of the design experiments were<br />
twofold. First, we <strong>in</strong>vestigated the effects of SBI on the<br />
acquisition of skills for solv<strong>in</strong>g mathematical word problems<br />
by third graders and explored the differential effects of<br />
SBI for different groups of children (e.g., children with<br />
learn<strong>in</strong>g disabilities; low, average, and high achievers). Second,<br />
we exam<strong>in</strong>ed the <strong>in</strong>fluence of word problem-solv<strong>in</strong>g<br />
<strong>in</strong>struction on the acquisition of computational skills given<br />
the role that word problems play <strong>in</strong> the development of<br />
number operations (Van de Walle, 2004).<br />
The basic methods were similar across both studies. In<br />
Study 1, we addressed the issue of the efficacy of SBI for a<br />
homogeneous sample of students from low-ability mathematics<br />
classrooms and potential differences between students<br />
with learn<strong>in</strong>g disabilities and students without disabilities<br />
who were low achievers. Study 2 focused on the<br />
efficacy of SBI for a heterogeneous sample of third graders,<br />
<strong>in</strong>clud<strong>in</strong>g students differ<strong>in</strong>g <strong>in</strong> <strong>in</strong>itial mathematics gradelevel<br />
achievement.<br />
DESIGN STUDY 1<br />
Method<br />
Participants<br />
Participants <strong>in</strong>cluded 40 third-grade students who<br />
attended an elementary school <strong>in</strong> a suburban school district<br />
<strong>in</strong> Pennsylvania serv<strong>in</strong>g 472 students <strong>in</strong> <strong>Grade</strong>s K–5.<br />
Approximately 15% of the student population was African<br />
American, Hispanic, or Asian; 17% were economically disadvantaged;<br />
and 5% were English language learners (ELLs).<br />
<strong>Third</strong>-grade students were grouped accord<strong>in</strong>g to ability levels<br />
(two low- and two high-ability classrooms). Teachers <strong>in</strong><br />
the two low-ability third-grade classrooms (Classrooms 1<br />
and 2), as well as the special education teacher (Classroom<br />
3), participated to learn about <strong>in</strong>novative approaches to<br />
improv<strong>in</strong>g students’ mathematical problem-solv<strong>in</strong>g performance.<br />
The f<strong>in</strong>al sample, however, comprised 38 students<br />
(20 boys and 18 girls) because 2 students moved out of the<br />
school district before complet<strong>in</strong>g the study. The mean<br />
chronological age of students was 102.60 months (range =<br />
91 to 119 months; SD = 5.54). Twenty-eight students (74%)<br />
were Caucasian, 3 (8%) were African American, 6 (16%)<br />
were Hispanic, and 1 was Middle Eastern (3%).<br />
The sample <strong>in</strong>cluded 9 students (6 boys and 3 girls) with<br />
learn<strong>in</strong>g disabilities (LD). While 3 of the students with LD<br />
received <strong>in</strong>struction <strong>in</strong> the general education classrooms,

the rema<strong>in</strong><strong>in</strong>g 6 students were <strong>in</strong>structed <strong>in</strong> the learn<strong>in</strong>g<br />
support classroom. In addition, we designated 9 of the 38<br />
students as low achievers (LA) on the basis of their score<br />
(below the 35th percentile) on the Computation and Concepts<br />
and Applications subtests of the TerraNova mathematics<br />
achievement test (CTB/McGraw-Hill, 2001).<br />
Tables 2 and 3 show a summary of participant demographic<br />
<strong>in</strong>formation by classroom and group status.<br />
Separate one-way analyses of variance (ANOVAs) <strong>in</strong>dicated<br />
no significant differences between classrooms on the<br />
mathematics subtests of the TerraNova: Concepts and<br />
Application, F(2, 35) = 0.38, ns, and Computation, F(2,<br />
35) = 0.80, ns; Total Read<strong>in</strong>g subtest, F(2, 35) = 1.03, ns.<br />
However, there was a significant difference between classrooms<br />
on chronological age, F(2, 35) = 15.99, p < .000.<br />
The mean age of special education students <strong>in</strong> Classroom 3<br />
was greater than that of students <strong>in</strong> Classrooms 1 and 2,<br />
which we expected given that the special education students<br />
were <strong>in</strong> the third and fourth grades. Chi-square<br />
analyses revealed no significant between-classroom differences<br />
on gender, χ 2 (2, N = 38) = 2.57, ns, and race, χ 2 (6,<br />
N = 38) = 8.68, ns.<br />
Similarly, separate one-way ANOVAs <strong>in</strong>dicated no significant<br />
between-group (LD and LA) differences on the Concepts<br />
and Application subtest of the TerraNova, F(1, 16) =<br />
2.84, ns, and on the Total Read<strong>in</strong>g subtest, F(1, 16) = 1.96,<br />
ns. However, there was a significant between-group difference<br />
on the Computation subtest, F(1, 16) = 5.53, p < .05.<br />
The mean score for students with LD was greater than that<br />
for LA students. In addition, there was a significant betweengroup<br />
difference on chronological age, F(1, 16) = 10.73, p <<br />
.01. The mean age of LD students was greater than was that<br />
of LA students. Chi-square analyses revealed no significant<br />
between-group differences on gender, χ 2 (1, N = 18) = .90,<br />
ns, and race, χ 2 (2, N = 18) = 1.62, ns.<br />
Three female teachers participated <strong>in</strong> Study 1, each<br />
teach<strong>in</strong>g <strong>in</strong> one classroom. The two general education<br />
teachers were certified <strong>in</strong> elementary education and each<br />
had more than 25 years of teach<strong>in</strong>g experience; the special<br />
education teacher was certified <strong>in</strong> special education and<br />
had 19 years of teach<strong>in</strong>g experience. Teachers attended 1<br />
hr of <strong>in</strong>service tra<strong>in</strong><strong>in</strong>g on ways to implement the <strong>in</strong>tervention;<br />
they received ongo<strong>in</strong>g support from two research<br />
assistants (doctoral students <strong>in</strong> special education) throughout<br />
the study.<br />
Procedures<br />
In all classrooms, teachers taught mathematics five times<br />
a week for 50 m<strong>in</strong> with the district-adopted basal text,<br />
Heath Mathematics Connections (Manfre, Moser, Lobato, &<br />
Morrow, 1994). Teachers taught the word problem-solv<strong>in</strong>g<br />
unit dur<strong>in</strong>g regularly scheduled mathematics <strong>in</strong>struction for<br />
15 weeks. They taught students how to solve one-step addition<br />
and subtraction problems <strong>in</strong>volv<strong>in</strong>g change, group,<br />
and compare problems for 30 m<strong>in</strong> daily, 3 days per week.<br />
Instruction was scripted to ensure consistency of <strong>in</strong>formation<br />
and <strong>in</strong>cluded an <strong>in</strong>structional paradigm of teacher<br />
model<strong>in</strong>g with th<strong>in</strong>k-alouds, followed by guided practice,<br />
paired partner work, <strong>in</strong>dependent practice, and homework.<br />
In addition, <strong>in</strong>struction dur<strong>in</strong>g guided practice emphasized<br />
frequent teacher–student exchanges to facilitate problem<br />
solv<strong>in</strong>g. <strong>Word</strong> problem-solv<strong>in</strong>g <strong>in</strong>struction <strong>in</strong>volved two<br />
phases: (a) problem schema and (b) problem solution. We<br />
developed a strategy checklist to help scaffold student<br />
learn<strong>in</strong>g. The checklist <strong>in</strong>cluded the follow<strong>in</strong>g six steps: (a)<br />
read and retell the problem to discover the problem type:<br />
(b) underl<strong>in</strong>e and map important <strong>in</strong>formation <strong>in</strong> the word<br />
problem onto the schematic diagram, (c) decide whether to<br />
add or subtract to solve the problem, (d) write the mathematics<br />
sentence and solve it, (e) write the complete answer,<br />
and (f) check the answer.<br />
Schema for <strong>Problem</strong>-<strong>Solv<strong>in</strong>g</strong> Instruction<br />
Dur<strong>in</strong>g the problem-solv<strong>in</strong>g phase, students received<br />
story situations that did not conta<strong>in</strong> any unknown <strong>in</strong>formation.<br />
Instruction focused on identify<strong>in</strong>g the problem<br />
schema for each of the three problem types (change, group,<br />
compare) and on represent<strong>in</strong>g the features of the story situation<br />
with schematic diagrams (see Figure 1). That is, students<br />
learned to <strong>in</strong>terpret and elaborate on the ma<strong>in</strong> features<br />
of the story situation and map the details of the story<br />
onto the schema diagram. Teachers <strong>in</strong>troduced each problem<br />
type successively and cumulatively reviewed them to<br />
help students discern the three problem types.<br />
Change story situation. Students learned to identify the<br />
problem type by us<strong>in</strong>g story situations such as, “Jane had<br />
four video games. Then her mother gave her three more<br />
video games for her birthday. Jane now has seven video<br />
games.” Us<strong>in</strong>g Step 1 of the strategy checklist, students<br />
identified the story situation as change because it <strong>in</strong>itially<br />
<strong>in</strong>volved four video games, then an action occurred that<br />
<strong>in</strong>creased this quantity by three, which resulted <strong>in</strong> a total<br />
of seven video games. Also, the object identity of the<br />
beg<strong>in</strong>n<strong>in</strong>g, change, and end<strong>in</strong>g is video games. As such,<br />
this story situation is considered a change problem<br />
schema. For Step 2, teachers prompted students to use the<br />
correspond<strong>in</strong>g diagram (see Figure 1) to organize or represent<br />
the <strong>in</strong>formation. That step <strong>in</strong>volved identify<strong>in</strong>g and<br />
writ<strong>in</strong>g the object identity or label (e.g., video games) for<br />
the three items of <strong>in</strong>formation (i.e., beg<strong>in</strong>n<strong>in</strong>g, change,<br />
and end<strong>in</strong>g) <strong>in</strong> the change diagram. Students then read<br />
the story to f<strong>in</strong>d the quantities associated with the beg<strong>in</strong>n<strong>in</strong>g,<br />
change, and end<strong>in</strong>g and wrote them <strong>in</strong> the diagram.<br />
Next, students summarized the <strong>in</strong>formation <strong>in</strong> the story<br />
with the completed diagram and checked the accuracy of<br />
the representation.<br />
Group story situation. Students identified the group story<br />
problem type by us<strong>in</strong>g story situations such as, “Sixty-eight<br />
students at Hillcrest Elementary took part <strong>in</strong> the school<br />
play. There were 22 third graders, 19 fourth graders, and 27

checklist, students learned that because the story<br />
described a situation <strong>in</strong> which three small groups (third-,<br />
fourth-, and fifth-grade students) comb<strong>in</strong>e to form a large<br />
group (all students <strong>in</strong> the play), it is a story situation of the<br />
group problem type. For Step 2, teachers prompted students<br />
to use the group diagram (see Figure 1) to represent the<br />
<strong>in</strong>formation. Instruction <strong>in</strong>volved identify<strong>in</strong>g the three<br />

<strong>Problem</strong>-Solution Instruction<br />
Dur<strong>in</strong>g the problem solution phase that followed problem<br />
schema <strong>in</strong>struction, students solved problems with<br />
unknowns by us<strong>in</strong>g either addition or subtraction; SBI <strong>in</strong><br />
this phase <strong>in</strong>cluded six steps.<br />
Change problems. Teachers prompted students to identify<br />
and represent the problem (i.e., Steps 1 and 2) with the<br />
change schematic diagram similar to the problem schema<br />
<strong>in</strong>struction phase. The only difference was that students<br />
used a question mark to represent the unknown quantity <strong>in</strong><br />
the diagram. Step 3 <strong>in</strong>volved select<strong>in</strong>g the appropriate<br />
operation and transform<strong>in</strong>g the <strong>in</strong>formation <strong>in</strong> the diagram<br />
<strong>in</strong>to a number sentence. That is, students learned that they<br />
needed to add the parts if the whole was unknown and subtract<br />
for the part when the whole was known. Instruction<br />
emphasized that when the change action caused an<br />
<strong>in</strong>crease, the end<strong>in</strong>g quantity represented the whole; when<br />
the change action <strong>in</strong>volved a decrease, the beg<strong>in</strong>n<strong>in</strong>g<br />
quantity was the whole. For Step 4, students had to write<br />
the mathematics sentence and solve for the unknown us<strong>in</strong>g<br />
the operation identified <strong>in</strong> the previous step. Step 5<br />
prompted students to write a complete answer. F<strong>in</strong>ally, for<br />
Step 6, students had to check the reasonableness of their<br />
answer and ensure the accuracy of the representation and<br />
computation.<br />
Group problems. Students learned to identify and represent<br />
the problem (i.e., Steps 1 and 2) with the group<br />
schematic diagram as <strong>in</strong> the problem schema <strong>in</strong>struction<br />
phase. For Step 3, when select<strong>in</strong>g the operation to solve for<br />
the unknown quantity <strong>in</strong> group problems, students learned<br />
that the large group represents the whole and the small<br />
groups are the parts that make up the whole. Steps 4<br />
through 6 were identical to those described for the change<br />
problem.<br />
Compare problems. Students identified and represented<br />
the problem (i.e., Steps 1 and 2) us<strong>in</strong>g the compare<br />
schematic diagram as <strong>in</strong> the problem schema <strong>in</strong>struction<br />
phase. For Step 3, when select<strong>in</strong>g the operation to solve for<br />
the unknown quantity <strong>in</strong> compare problems, students<br />
learned that the larger set is the big number or whole,<br />
whereas the smaller set and difference are the parts that<br />
make up the larger set. Steps 4 through 6 were identical to<br />
those described for the change and group problems.<br />
When <strong>in</strong>structors taught students to solve word problems<br />
us<strong>in</strong>g SBI, only one type of story situation or word<br />
problem with the correspond<strong>in</strong>g schema diagram <strong>in</strong>itially<br />
appeared on student worksheets follow<strong>in</strong>g the <strong>in</strong>struction<br />
of that problem type (e.g., change problem). After students<br />
learned how to map the features onto schematic diagrams<br />
or solve change and group problems, teachers presented<br />
story situations or word problems with both types, along<br />
with a discussion of the samenesses and differences between<br />
the change and group problems. Later, when students completed<br />
<strong>in</strong>struction for change, group, and compare problem<br />
types, teachers distributed worksheets with word problems<br />
that <strong>in</strong>cluded all problem types.<br />
We measured fidelity of treatment with a checklist of<br />
critical <strong>in</strong>structional steps. The checklist <strong>in</strong>cluded salient<br />
<strong>in</strong>structional features (e.g., provid<strong>in</strong>g clear <strong>in</strong>structions,<br />
read<strong>in</strong>g word problems aloud, model<strong>in</strong>g the strategy application,<br />
provid<strong>in</strong>g guided practice). Two graduate students<br />
<strong>in</strong> special education collected fidelity data as they observed<br />
one of the <strong>in</strong>structors for approximately 30% of the teach<strong>in</strong>g<br />
sessions. Treatment fidelity, estimated as the percentage<br />
of steps completed correctly by the <strong>in</strong>structor, was 93%<br />
(range = 85–100%) across the 3 teachers.<br />
Measures and Data Collection<br />
Two research assistants adm<strong>in</strong>istered and scored the<br />
mathematical word problem-solv<strong>in</strong>g tests and computation<br />
tests with scripted directions and answer keys. All data<br />
were collected <strong>in</strong> a whole-class arrangement.<br />
<strong>Word</strong> problem-solv<strong>in</strong>g criterion referenced test (WPS-CRT).<br />
To assess student growth on third-grade addition and subtraction<br />
word problems, students completed the WPS-CRT<br />
prior to and at the end of the <strong>in</strong>tervention. The test consisted<br />
of 25 one-step and two-step addition and subtraction<br />
word problems. Part I of the CRT comprised 9 one-step<br />
word problems derived from the Test of <strong>Mathematical</strong><br />
Achievement (Brown, Cron<strong>in</strong>, & McEntire, 1994). Of the<br />
9 problems, 5 items <strong>in</strong>cluded distracters. Part II of the WPS-<br />
CRT <strong>in</strong>cluded 16 addition and subtraction word problems<br />
selected from five commonly used third-grade mathematics<br />
textbooks. The items consisted of 12 one-step and 4 twostep<br />
problems that met the semantic criteria for change,<br />
group, and compare problem types. In addition, 2 of the<br />
problems <strong>in</strong>cluded distracters. The design of the measure<br />
<strong>in</strong>cluded the three problem types and both operations.<br />
<strong>Word</strong> problems on Parts I and II of the WPS-CRT<br />
required apply<strong>in</strong>g simple (e.g., s<strong>in</strong>gle-digit numbers) to<br />
complex computation skills (e.g., three- and four-digit<br />
numbers; regroup<strong>in</strong>g). Students had 50 m<strong>in</strong> to complete<br />
the test. Directions for adm<strong>in</strong>ister<strong>in</strong>g the word problemsolv<strong>in</strong>g<br />
test required students to show their complete work<br />
and to write the answer and label. Scor<strong>in</strong>g <strong>in</strong>volved assign<strong>in</strong>g<br />
one po<strong>in</strong>t for the correct number model and one po<strong>in</strong>t<br />
for correct answer and label for a possible total score of 2<br />
po<strong>in</strong>ts for each item. Cronbach’s alpha for each of the<br />
pretest and posttest measures was 0.84. Interscorer agreement<br />
assessed by two research assistants <strong>in</strong>dependently<br />
scor<strong>in</strong>g 30% of the protocols was .92 at pretreatment and<br />
.97 at postreatment.

<strong>Word</strong> problem-solv<strong>in</strong>g fluency (WPS-F) measure. We<br />
developed six forms to represent items <strong>in</strong> Part II of the<br />
WPS-CRT but modified them to <strong>in</strong>clude fewer problems,<br />
less advanced computation (one- and two-digit numbers<br />
only), and no problems with distracters to address the<br />
timed nature of the task. The problems for each WPS-fluency<br />
probe differed with respect to numbers, context, and<br />
position of problems, which were random. Given that each<br />
probe <strong>in</strong>cluded only half the number of problems on the<br />
WPS-CRT, the probes were not identical and differed with<br />
respect to the unknown quantity to be solved (e.g., result,<br />
beg<strong>in</strong>n<strong>in</strong>g, compared). We covered all possible comb<strong>in</strong>ations<br />
of problem types and operations <strong>in</strong> two probes rather<br />
than one probe. To control for the difficulty of the probes,<br />
we designed odd- and even-numbered probes to be parallel<br />
forms. Teachers adm<strong>in</strong>istered the probes every 3 weeks to<br />
monitor students’ progress <strong>in</strong> solv<strong>in</strong>g word problems. Students<br />
had 10 m<strong>in</strong> to complete eight problems. For the purpose<br />
of this study, we used the comb<strong>in</strong>ed score of the first<br />
two probes and the comb<strong>in</strong>ed score of the last two probes<br />
<strong>in</strong> the data analysis. Cronbach’s alphas for the two aggregated<br />
probes were 0.83 and 0.80, respectively. Interscorer<br />
agreement was .93 at pretreatment and .98 at postreatment.<br />
Basic mathematics computation fluency measure (Fuchs,<br />
Hamlett, & Fuchs, 1998). We monitored student progress<br />
toward proficiency on third-grade mathematics computation<br />
curriculum prior to and at the completion of the <strong>in</strong>tervention<br />
with basic mathematics computation probes. Students<br />
had 3 m<strong>in</strong> to complete 25 problems, with a maximum<br />
score of 43 correct digits. We scored the performance on the<br />
computation probes as the total number of correct digits,<br />
which provided credit for correct segments of responses.<br />
That assessment system is known to have adequate reliability<br />
and validity (see Fuchs, Fuchs, Hamlett, & All<strong>in</strong>der,<br />
1989). Interscorer agreement was .99 at pretreatment and<br />
1.00 at postreatment.<br />
Strategy satisfaction questionnaire. We developed and<br />
adm<strong>in</strong>istered a strategy-satisfaction questionnaire follow<strong>in</strong>g<br />
the <strong>in</strong>tervention to provide <strong>in</strong>formation about student perceptions<br />
regard<strong>in</strong>g the problem-solv<strong>in</strong>g strategy <strong>in</strong>tervention<br />
(i.e., SBI). The questionnaire <strong>in</strong>cluded five items that<br />
required students to rate whether they (a) enjoyed the<br />
strategy, (b) found the diagrams helpful <strong>in</strong> understand<strong>in</strong>g<br />
and solv<strong>in</strong>g problems, (c) improved their problem-solv<strong>in</strong>g<br />
skills, (d) would recommend us<strong>in</strong>g the strategy with other<br />
students, and (e) would cont<strong>in</strong>ue to use it to solve word<br />
problems <strong>in</strong> the classroom. Rat<strong>in</strong>gs for the Likert-type<br />
items on the questionnaire ranged from a high score of 5<br />
(strongly agree) to a low score of 1 (strongly disagree). Cronbach’s<br />
alpha for the questionnaire was 70.<br />
Data Analysis<br />
The unit of analysis was each student’s <strong>in</strong>dividual score<br />
(N = 16 for the general education classrooms; n = 6 for the<br />
special education classroom) rather than the classroom<br />
because of sample limitations. On the WPS-CRT, WPS-F,<br />
and computation pretest measures, we conducted separate<br />
one-way, between-subjects (classroom or group) analysis of<br />
variance (ANOVA) to exam<strong>in</strong>e <strong>in</strong>itial classroom or group<br />
(LD and LA) comparability. On the WPS-CRT, WPS-F,<br />
and computation pretest and posttest scores, we conducted<br />
a one between-subjects (classroom or group), one with<strong>in</strong>subjects<br />
(time: pretest vs. posttest) ANOVA. We used the<br />
Fisher least significance difference (LSD) post-hoc procedure<br />
to evaluate any pairwise comparisons for significant<br />
effects for the full sample. If a lack of classroom or group<br />
comparability on pretreatment measures occurred, we conducted<br />
a one-factor ANOVA on the change scores, with<br />
classroom or group as the between-subjects factor. (We<br />
used change scores for analyz<strong>in</strong>g the two-wave data because<br />
their <strong>in</strong>terpretation is straightforward.) In addition, we<br />
analyzed scores from the strategy questionnaire with multivariate<br />
analysis of variance (MANOVA) with teacher or<br />
group as the between-subjects factor. To estimate the practical<br />
significance of effects for classroom and group, we<br />
computed effect sizes (ESs) by subtract<strong>in</strong>g the difference<br />
between the posttest means, then divid<strong>in</strong>g by the pooled<br />
standard deviation of the posttest. On the computation<br />
measure, we calculated improvement effects by divid<strong>in</strong>g<br />
the difference between the improvement means by the<br />
pooled standard deviation of the improvement divided by<br />
the square root of 2(1– rxy; Glass, McGraw, & Smith,<br />
1981).<br />
Results<br />
Table 2 shows the means and standard deviations for all<br />
measures for the full sample; Table 3 shows means and standard<br />
deviations for the measures by group (LD and LA).<br />

Discussion<br />
Results must be <strong>in</strong>terpreted <strong>in</strong> light of two serious limitations.<br />
First, the full sample (N = 38) and group sample<br />
sizes (n = 9 each for LD and LA students) were small. Second,<br />
the design was unbalanced; classroom sizes ranged<br />
from 16 to 6 students. As such, the f<strong>in</strong>d<strong>in</strong>gs <strong>in</strong>dicate only<br />
prelim<strong>in</strong>ary evidence regard<strong>in</strong>g the effectiveness of SBI.<br />
With<strong>in</strong> the constra<strong>in</strong>ts of the limitations, results from<br />
Study 1 provide evidence that SBI led to improvements <strong>in</strong><br />
word problem-solv<strong>in</strong>g performance for the three classrooms.<br />
Although the overall treatment fidelity was high,<br />
teach<strong>in</strong>g styles varied concern<strong>in</strong>g teachers’ adherence to<br />
the scripted curriculum (i.e., read verbatim or used their<br />
own explanations). The high level of treatment fidelity<br />
f<strong>in</strong>d<strong>in</strong>g suggests that SBI accounted for improved student<br />
learn<strong>in</strong>g, which is encourag<strong>in</strong>g.<br />
Furthermore, SBI was effective <strong>in</strong> enhanc<strong>in</strong>g the word<br />
problem-solv<strong>in</strong>g performance of students with LD, whether<br />
they received <strong>in</strong>struction <strong>in</strong> general education mathematics<br />
classrooms or <strong>in</strong> a special education classroom. When<br />
we separated outcomes on the word problem-solv<strong>in</strong>g measures<br />
for students with LD and their LA peers, the effects of<br />
the word problem-solv<strong>in</strong>g curriculum on students’ performance<br />
was comparable for both groups. Those results are<br />
notable because teachers implemented the treatment <strong>in</strong> a<br />
whole-class format and taught students to solve only onestep<br />
problems, although students were tested on one-step<br />
and two-step problems. The f<strong>in</strong>d<strong>in</strong>gs support and extend<br />
previous research regard<strong>in</strong>g the effectiveness of SBI <strong>in</strong> solv<strong>in</strong>g<br />
arithmetic word problems (e.g., Fuchs, Fuchs, F<strong>in</strong>elli,<br />
Courey, & Hamlett, 2004; Jitendra et al., 1998; Zawaiza &<br />
Gerber, 1993).<br />
Our results <strong>in</strong>dicated that classrooms and groups were<br />
not comparable on their computational skills prior to the<br />
study and that computational skill improvement varied as<br />
a function of classroom and group. In general, students with<br />
LD at pretreatment demonstrated better computational

skills than did the other students at pretreatment. We<br />
expected that result given that many of those students were<br />
older students receiv<strong>in</strong>g <strong>in</strong>struction <strong>in</strong> a special education<br />
classroom <strong>in</strong> which the focus of <strong>in</strong>struction was on the<br />
acquisition of basic skills. However, the general f<strong>in</strong>d<strong>in</strong>g<br />
that computation improvement was evident for all students<br />
was encourag<strong>in</strong>g because opportunities for word problem<br />
solv<strong>in</strong>g facilitate computation skills. The effect size for<br />
posttest over pretest was large for the entire sample (ES =<br />
2.98) and for the LD and LA students (ES = 2.16). Evidently,<br />
hav<strong>in</strong>g students solve story problems enhanced the<br />
development of number operations or computational skills.<br />
The use of schematic diagrams, which provided mean<strong>in</strong>g to<br />
number sentences, had an added value <strong>in</strong> promot<strong>in</strong>g computation<br />
(Van De Walle, 2004).<br />
F<strong>in</strong>ally, the positive evaluation of SBI by students <strong>in</strong> the<br />
study seemed to play a role <strong>in</strong> enhanc<strong>in</strong>g mathematics performance<br />
as <strong>in</strong> several previous <strong>in</strong>vestigations (e.g., Case,<br />
Harris, & Graham, 1992; Jitendra et al., 1999). Students<br />
with learn<strong>in</strong>g disabilities especially were more enthused<br />
about SBI than were their peers with regard to treatment<br />
acceptability and benefits. Wood, Frank, and Wacker<br />
(1998) stated that “Student preference is an important factor,<br />
because students are not as likely to exhibit effort over<br />
time with strategies that they do not like or do not feel are<br />
helpful” (p. 336).<br />
Overall, the study helped us learn about effective ways to<br />
enhance the problem-solv<strong>in</strong>g curriculum as well as facilitate<br />
teacher implementation and student learn<strong>in</strong>g. Teachers<br />
became conversant about modify<strong>in</strong>g the curriculum<br />
only when they had completed the problem-solv<strong>in</strong>g unit<br />
on teach<strong>in</strong>g change and group problems. The lessons that<br />
we learned from our observations and teacher <strong>in</strong>put (prior<br />
to <strong>in</strong>struction on compare problems) dur<strong>in</strong>g SBI implementation<br />
allowed us to make several modifications that<br />
we organized <strong>in</strong> the follow<strong>in</strong>g paragraphs accord<strong>in</strong>g to curriculum,<br />
teacher, and student enhancements.<br />
Curriculum<br />
Although Marshall (1995) discussed the importance of<br />
present<strong>in</strong>g problem schema <strong>in</strong>struction <strong>in</strong> concert with the<br />
three problem types followed by problem-solution <strong>in</strong>struction,<br />
teachers raised concerns that problem solution was<br />
seem<strong>in</strong>gly removed from problem schema <strong>in</strong>struction for<br />
each problem type. Therefore, we revised the curriculum<br />
such that <strong>in</strong>struction for the change problem type began<br />
with problem schema <strong>in</strong>struction, followed by problem<br />
solution <strong>in</strong>struction. We used that same sequence for group<br />
and compare problem types.<br />
We redesigned the self-monitor<strong>in</strong>g strategy checklist to<br />
<strong>in</strong>clude four steps, and used an acronym, FOPS (F<strong>in</strong>d the<br />
problem type, Organize <strong>in</strong>formation <strong>in</strong> the problem us<strong>in</strong>g<br />
the schema diagram, Plan to solve the problem, and Solve<br />
the <strong>Problem</strong>), to help students remember the steps. Furthermore,<br />
we elaborated on each step to align with<br />
doma<strong>in</strong>-specific knowledge consistent with SBI. For example,<br />
to f<strong>in</strong>d the problem type (Step 1), we prompted students<br />
to exam<strong>in</strong>e <strong>in</strong>formation perta<strong>in</strong><strong>in</strong>g to each set<br />
(beg<strong>in</strong>n<strong>in</strong>g, change, and end<strong>in</strong>g) <strong>in</strong> the problem (e.g.,<br />
change).<br />
Given that the compare problem type was difficult for<br />
many students dur<strong>in</strong>g the problem schema phase, we collaborated<br />
with teachers to develop a compare structure that<br />
was coherent to third-grade students. For example, we<br />
focused on three sets (bigger, smaller, and difference) of<br />
<strong>in</strong>formation and elim<strong>in</strong>ated reference to difficult terms<br />
(e.g., compared, referent) when discuss<strong>in</strong>g the problem. In<br />
addition, we added oral exercises prior to written work to<br />
emphasize the critical features and relations <strong>in</strong> the problem<br />
to ensure that students were familiar with the <strong>in</strong>formation<br />
needed for problem comprehension, a key aspect of SBI.<br />
We found that teachers were spend<strong>in</strong>g considerable<br />
amounts of <strong>in</strong>structional time expla<strong>in</strong><strong>in</strong>g unfamiliar terms<br />
to students who did not have the necessary experiential<br />
background, which detracted from the focus on problem<br />
solv<strong>in</strong>g. Therefore, we modified the textbook problems to<br />
meet the needs of the students. For example, unknown<br />
words such as “alpaca” were replaced by more familiar terms<br />
(sheep).<br />
An important issue that emerged was teacher accountability<br />
for student performance on statewide test<strong>in</strong>g. Teachers<br />
believed that the use of word problems presented only<br />
<strong>in</strong> text format would not adequately prepare students to<br />
generalize to word problems on the state mathematics test.<br />
Therefore, revisions to the problem-solv<strong>in</strong>g curriculum<br />
content entailed <strong>in</strong>clusion of items that presented <strong>in</strong>formation<br />
<strong>in</strong> tables, graphs, and pictographs. Also, because the<br />
state test required the use of mathematical vocabulary (e.g.,<br />
addend) and emphasized written communication, we modified<br />
our <strong>in</strong>struction to <strong>in</strong>clude key mathematical terms and<br />
provided students with practice <strong>in</strong> writ<strong>in</strong>g explanations for<br />
how the problem was solved.<br />
Furthermore, teachers noted that the time required to<br />
implement SBI was unrealistic given the need to cover<br />
other topics <strong>in</strong> the school curriculum. In the redesign of the<br />
problem-solv<strong>in</strong>g curriculum, we reduced problem schema<br />
<strong>in</strong>struction for each problem type from three 30-m<strong>in</strong><br />
lessons to one 50-m<strong>in</strong> lesson and developed four lessons for<br />
each problem type that addressed problem solution <strong>in</strong>struction.<br />
In addition, we <strong>in</strong>corporated fad<strong>in</strong>g of schematic diagrams<br />
to ensure that students were able to apply learned<br />
solution procedures <strong>in</strong>dependent of diagrams. Also, we<br />
elim<strong>in</strong>ated homework problems from the curriculum<br />
because of teacher concerns regard<strong>in</strong>g students’ <strong>in</strong>consistent<br />
completion of homework.<br />
Teachers<br />
Our observations revealed that teachers need ongo<strong>in</strong>g<br />
support dur<strong>in</strong>g the <strong>in</strong>itial implementation of a newly developed<br />
<strong>in</strong>tervention. Although we provided teach<strong>in</strong>g scripts
283-302 Jitendra M_J 07 5/8/07 10:57 AM Page 295<br />

to ensure consistency <strong>in</strong> implement<strong>in</strong>g the critical content,<br />
we suggested that teachers use them as a framework for<br />
<strong>in</strong>structional implementation. However, our observations<br />
<strong>in</strong>dicated that Teacher 1 read the script verbatim and followed<br />
it <strong>in</strong> its entirety, whereas Teacher 2 followed the<br />
script <strong>in</strong>consistently and required rem<strong>in</strong>ders to adhere to<br />
the relevant <strong>in</strong>formation needed to promote problem solv<strong>in</strong>g.<br />
In contrast, Teacher 3 (special education teacher)<br />
familiarized herself with the script and used her own explanations<br />
and elaborations to implement the <strong>in</strong>tervention<br />
with ease. Obviously, general education teachers <strong>in</strong> this<br />
study needed more support to implement the <strong>in</strong>tervention.<br />
Also, we noticed that some students <strong>in</strong> one classroom were<br />
struggl<strong>in</strong>g dur<strong>in</strong>g partner work and had to wait until wholeclass<br />
discussion to get corrective feedback, <strong>in</strong>dicat<strong>in</strong>g the<br />
need for provid<strong>in</strong>g teachers with explicit guidel<strong>in</strong>es about<br />
direct monitor<strong>in</strong>g student work.<br />
In addition, we found that the general education teachers<br />
seemed more at ease <strong>in</strong> communicat<strong>in</strong>g their concerns<br />
to the two research assistants who supported them dur<strong>in</strong>g<br />
the course of the project than to the primary researcher,<br />
which raised the issue of how and with whom communication<br />
should be facilitated.<br />
Students<br />
Our observations <strong>in</strong>dicated that for many students, especially<br />
those with LD, scaffold<strong>in</strong>g <strong>in</strong>struction (model<strong>in</strong>g, use<br />
of schematic diagrams and checklists) was critical as they<br />
learned to apply the strategy. Explicit model<strong>in</strong>g and explanations<br />
us<strong>in</strong>g several examples enhanced their problemsolv<strong>in</strong>g<br />
skills. Follow<strong>in</strong>g teacher-led <strong>in</strong>struction, we noticed<br />
that several students with LD, as well as low-achiev<strong>in</strong>g students,<br />
were enthused and participated actively, as evidenced<br />
by their raised hands <strong>in</strong> response to teacher question<strong>in</strong>g.<br />
DESIGN STUDY 2<br />
Method<br />
Participants<br />
Students <strong>in</strong> Study 2 were 56 third-grade students <strong>in</strong> two<br />
heterogeneous classrooms <strong>in</strong> a parochial school located <strong>in</strong><br />
a small city <strong>in</strong> Florida that served 570 students <strong>in</strong> <strong>Grade</strong>s<br />
pre-K–8. Approximately 20% of the student population<br />
was African American, Hispanic, or Asian. The total sample<br />
<strong>in</strong>cluded 27 boys and 29 girls. The mean chronological<br />
age of the students was 108 months (range = 96 to 113<br />
months). Forty-four of the students (78%) were Caucasian,<br />
5 (8%) were African American, 6 (10%) were Hispanic,<br />
and 1 was Asian American (2%). Although not formally<br />
identified at the school, the two third-grade classroom<br />
teachers reported that 9 of the 56 third-grade students had<br />
either LD, attention deficit disorder, or were considered<br />
low achievers. On the basis of scores from the <strong>Problem</strong><br />
<strong>Solv<strong>in</strong>g</strong> and Data Interpretation (PSDI) mathematics subtest<br />
of the Iowa Test of Basic Skills (ITBS), we designated<br />
each student’s <strong>in</strong>itial mathematics achievement status as<br />
low perform<strong>in</strong>g (LO; below the 34th percentile), average<br />
perform<strong>in</strong>g (AV; between the 35th and 66th percentiles),<br />
or high perform<strong>in</strong>g (HI; above the 66th percentile). Tables<br />
4 and 5 summarize participant demographic <strong>in</strong>formation by<br />
the two classrooms and by student type (LO, AV, and HI<br />
students).<br />
Separate one-way analysis of variances (ANOVAs) <strong>in</strong>dicated<br />
no significant differences between classrooms on the<br />
mathematics and read<strong>in</strong>g subtests of the ITBS, <strong>Problem</strong><br />
<strong>Solv<strong>in</strong>g</strong> and Data Interpretation, F(1, 54) = 0.11, ns; Computation,<br />
F(1, 54) = 0.04, ns; Vocabulary, F(1, 54) = 0.35,<br />
ns; and Comprehension, F(1, 54) = 0.01, ns. In addition,<br />
there was a lack of a significant difference between classrooms<br />
on chronological age, F(1, 54) = 0.31, ns. Chi-square<br />
analyses revealed no significant between-classroom differences<br />
on gender, χ 2 (1, N = 56) = .27, ns, and ethnicity,<br />
χ 2 (3, N = 56) = 1.96, ns.<br />
Similarly, separate one-way ANOVAs <strong>in</strong>dicated significant<br />
differences between student type (i.e., LO, AV, and<br />
HI) on the PSDI, F(2, 53) = 239.81, p < .000; computation,<br />
F(2, 53) = 9.498, p < .000; vocabulary, F(2, 53) =<br />
17.80, p < .000; and comprehension, F(2, 53) = 25.54, p <<br />
.000. For all analyses, LSD post-hoc tests revealed that the<br />
differences between the three groups were significant.<br />
(Performance of HI students > AV students > LO students.)<br />
In addition, there was no significant between-student<br />
type difference on chronological age, F(2, 53) = 0.95,<br />
ns. Chi-square analyses revealed no significant betweenstudent<br />
type differences on gender, χ 2 (2, N = 56) = 0.27,<br />
ns, or race χ 2 (6, N = 56) = 1.96, ns.<br />
The two general education teachers who participated <strong>in</strong><br />
Study 2 were women; one teacher held a master’s degree<br />
with 10 years’ teach<strong>in</strong>g experience, and the other teacher,<br />
a bachelor’s degree with 30 years’ experience. The teachers<br />
attended 1 hr of <strong>in</strong>service tra<strong>in</strong><strong>in</strong>g on ways to implement<br />
the <strong>in</strong>tervention; they received support from one of the<br />
researchers periodically throughout the study.<br />
Procedures and Measures<br />
Procedures and measures were similar to those used <strong>in</strong><br />
Study 1. In this section, we report only how components of<br />
the two studies differed. First, although students received the<br />
same amount of <strong>in</strong>structional time as those <strong>in</strong> Study 1,<br />
teachers began Study 2 later <strong>in</strong> the school year. Second,<br />
teachers <strong>in</strong> Study 2 used the textbook series, “Mathematics—The<br />
Path to Math Success! <strong>Grade</strong> 3” by Silver, Burdett,<br />
and G<strong>in</strong>n (as cited <strong>in</strong> Fennell et al., 1998) for daily mathematics<br />
<strong>in</strong>struction. <strong>Third</strong>, <strong>in</strong>structional procedures differed<br />
from Study 1 with regard to compare <strong>in</strong>struction. On the<br />
basis of student difficulty with the compare problem type,<br />
teachers <strong>in</strong> Study 1 used the revised compare diagram and<br />
<strong>in</strong>struction. However, teachers <strong>in</strong> Study 2 decided to implement<br />
the orig<strong>in</strong>al compare <strong>in</strong>struction and determ<strong>in</strong>e how

Pretreatment Differences Between Groups (LO, AV, and HI)<br />
on Mathematics Performance<br />
Results <strong>in</strong>dicated that, as expected, differences between<br />
groups on the WPS-CRT, F(2, 53) = 5.68, p < .000 and computation,<br />
F(2, 53) = 5.68, p < .01, were significant prior to<br />
the study.<br />
LSD follow-up tests <strong>in</strong>dicated that mean scores for HI<br />
were significantly different than were those for AV (p <<br />
.00) and LO (p < .00) on the WPS-CRT (HI > AV > LO).<br />
However, the difference between LO and AV was not significant.<br />
We found large effect sizes of 1.14 and 1.15 for HI<br />
when compared with AV and LO, respectively. For the<br />
WPS-F measure, follow-up tests <strong>in</strong>dicated that the mean<br />
scores for HI were significantly different than those for AV<br />
(p < .000) and LO (p < .000; HI > AV > LO). In addition,<br />
the difference between LO and AV was significant (p <<br />
.05), favor<strong>in</strong>g the AV group. On the WPS-F, we found large<br />
effect sizes of 1.26 for HI compared with AV, 2.51 for HI<br />
compared with LO, and 0.94 for AV compared with LO.<br />
F<strong>in</strong>ally, follow-up tests on the computation measure<br />
revealed that mean scores for HI were significantly different<br />
than were those for LO (p < .00; (HI > LO), but not<br />
between HI and AV (p = .15). The difference between LO<br />
and AV on the computation measure was also significant (p<br />
= .05); the AV group scored higher. We found large effect<br />
sizes of 1.67 and 0.91 for HI compared with the LO, and for<br />
AV compared with LO, respectively.<br />
Results of ANOVA applied to the WPS-CRT pretest<br />
and posttest data yielded no significant group by time of<br />
test<strong>in</strong>g <strong>in</strong>teraction, F(2, 53) = 1.19, ns. That f<strong>in</strong>d<strong>in</strong>g <strong>in</strong>dicated<br />
that group status (HI, AV, LO) had no effect on<br />
changes <strong>in</strong> correct scores from pretest to posttest. In addition,<br />
there was no significant ma<strong>in</strong> effect for time, F(1, 53)<br />
= 0.26, ns, <strong>in</strong>dicat<strong>in</strong>g lack of improvement from pretest to<br />
posttest for the entire sample of students, regardless of<br />
group status. However, the analysis yielded a significant<br />
ma<strong>in</strong> effect for group, F(2, 53) = 12.45, p < .000. The LSD<br />
follow-up test <strong>in</strong>dicated that WPS-CRT mean scores for HI<br />
students were significantly different from AV (p < .000)<br />
and LO (p < .000). We found effect sizes of 1.05 and 1.48<br />
for HI students when compared with AV and LO students,<br />
respectively, on the WPS-CRT. The difference between LO<br />
and AV, however, was not significant (p = .12).<br />
Results for WPS-F <strong>in</strong>dicated the follow<strong>in</strong>g significant<br />
effects: group by time of test<strong>in</strong>g <strong>in</strong>teraction, F(2, 53) =<br />
3.19, p < .05, time of test<strong>in</strong>g, F(1, 53) = 17.37, p < .000,<br />
and group status, F(2, 53) = 16.72 p < .000. Because the<br />
group by time of test<strong>in</strong>g <strong>in</strong>teraction supercedes ma<strong>in</strong><br />
effects, we conducted follow-up tests only for the significant<br />
<strong>in</strong>teraction. Follow-up tests <strong>in</strong>dicated that from<br />
pretest to posttest, averaged across all groups, the LO students<br />
improved reliably more than did the HI students (p =<br />
.02); the trend of improvement for LO students compared<br />
with AV students approached significance (p = .07); the<br />
growth of the AV and HI students was comparable (average<br />
growth for LO students = 5.61; SD = 5.81; AV students =<br />
2.13, SD = 4.04; HI students = 0.96, SD = 4.88). The effect<br />
size for LA growth compared with AV growth was 0.76; for<br />
LA compared with HI, 0.91; for AV compared with HI,<br />
0.26.<br />
The analysis of computation data yielded no significant<br />
group by time of test<strong>in</strong>g <strong>in</strong>teraction, F(1, 54) = 0.36, ns,<br />
<strong>in</strong>dicat<strong>in</strong>g that group status (HI, AV, LO) had no effect on<br />
changes <strong>in</strong> correct scores from pretest to posttest. However,<br />
results <strong>in</strong>dicated a significant ma<strong>in</strong> effect for time, F(1,<br />
53) = 18.84, p < .000, <strong>in</strong>dicat<strong>in</strong>g improvement from pretest<br />
to posttest for the entire sample of students, regardless of<br />
group status (M = 2.19; SD = 4.90). The effect size for time<br />
from posttest to pretest was 0.34. In addition, there was a<br />
significant ma<strong>in</strong> effect for group, F(2, 53) = 5.74, p < .01.<br />
The follow-up test for group <strong>in</strong>dicated that mean scores for<br />
HI students were significantly different than that for LO<br />
students (p < .00) but comparable to those for AV students<br />
(p = .20). In addition, the difference between LO and AV<br />
students was significant (p < .05). We found effect sizes of<br />
1.39 and 0.29 for HI students when compared with LO students,<br />
and for AV students compared with LO students,<br />
respectively.<br />
Discussion<br />
Students <strong>in</strong> Study 2 made small-to-moderate improvements<br />
<strong>in</strong> their word problem-solv<strong>in</strong>g and computation performance<br />
despite unforeseen problems that occurred dur<strong>in</strong>g<br />
this field-based research. The benefits of a SBI were particularly<br />
apparent for the low-perform<strong>in</strong>g students <strong>in</strong> the two<br />
heterogeneously grouped third-grade classrooms. As <strong>in</strong><br />
Study 1, third-grade teachers delivered <strong>in</strong>struction <strong>in</strong><br />
whole-class arrangement without special <strong>in</strong>structional<br />
adaptations for low-perform<strong>in</strong>g students. Despite the lack<br />
of <strong>in</strong>dividualized <strong>in</strong>struction, those students showed the<br />
greatest amount of growth from pretest to posttest on two<br />
of the three measures. Conversely, the results <strong>in</strong>dicated<br />
that the high-perform<strong>in</strong>g students made the least amount<br />
of improvement. The f<strong>in</strong>d<strong>in</strong>gs support previous studies<br />
regard<strong>in</strong>g the importance of explicit <strong>in</strong>struction for struggl<strong>in</strong>g<br />
learners (e.g., Swanson, 1999) and its triviality for<br />
high performers. Even young children with high <strong>in</strong>telligence<br />
are capable of us<strong>in</strong>g strategies spontaneously to perform<br />
given tasks without explicit <strong>in</strong>struction (Cho & Ahn,<br />
2003).<br />
Results for the WPS-CRT, <strong>in</strong> particular, were disappo<strong>in</strong>t<strong>in</strong>g.<br />
Our hypothesis that there would be a significant<br />
effect for time from pretest to the posttest was not realized.<br />
The lack of improvement over time may be attributed to<br />
several reasons. First, the length of the WPS-CRT task<br />
(i.e., 25 one-step and two-step word problems) <strong>in</strong> conjunction<br />
with adm<strong>in</strong>istration of the posttest only 2 weeks before

school ended for the summer may not have been motivat<strong>in</strong>g<br />
for students, <strong>in</strong> spite of explicit <strong>in</strong>structions to do their<br />
best. Teachers reported students’ less-than-determ<strong>in</strong>ed<br />
attempts to complete the test. As such, that problem could<br />
have negatively affected student performance on the WPS-<br />
CRT posttest, which is not uncommon to <strong>in</strong>tervention<br />
research (Dunst & Trivette, 1994).<br />
Another plausible explanation for a lack of improvement<br />
was that the high-perform<strong>in</strong>g students may have<br />
known how to solve third-grade word problems before the<br />
study began and did not require extensive strategy <strong>in</strong>struction.<br />
A closer look at the data suggests that that may be the<br />
case. Fifteen of the high-perform<strong>in</strong>g students scored close<br />
to an accepted criterion level of 80% correct before the<br />
study began, <strong>in</strong>dicat<strong>in</strong>g possible ceil<strong>in</strong>g effects (M = 39.91,<br />
SD = 3.99; range = 34 to 47 on the 50-po<strong>in</strong>t WPS-CRT).<br />
As such, pretest to posttest improvement was not evident<br />
for the students, and ceil<strong>in</strong>g effects limited the ability to<br />
ferret out differences among higher scor<strong>in</strong>g students.<br />
Results on the WPS-F measures were more encourag<strong>in</strong>g.<br />
All students improved their word problem-solv<strong>in</strong>g performance<br />
on the shorter, 8-item, probes from pretest to<br />
posttest. The LO group made the most progress on this<br />
measure, as evidenced by the large effect size of 0.79 when<br />
compared with effect sizes of 0.34 and 0.20 for the AV and<br />
HI groups, respectively. Given that the measure <strong>in</strong>cluded<br />
easier items than did the WPS-CRT, was shorter <strong>in</strong> length,<br />
and required only 10 m<strong>in</strong> to complete each probe, thereby<br />
reduc<strong>in</strong>g fatigue, it may have positively <strong>in</strong>fluenced the<br />
results of the WPS-F.<br />
The pretest-to-posttest results for the computation measure<br />
revealed a pattern similar to those for the WPS-F. All<br />
groups improved significantly over time; however, the LO<br />
group demonstrated the largest ga<strong>in</strong>s from pretest to<br />
posttest, with a medium effect size of .57 when compared<br />
with small-to-moderate effect sizes of .36 and .32 for the<br />
AV and HI students, respectively. Aga<strong>in</strong>, word problem<br />
solv<strong>in</strong>g seems to play a role <strong>in</strong> the development of number<br />
operations, such as computational skills (Van de Walle,<br />
2004), particularly for low-perform<strong>in</strong>g students.<br />
As <strong>in</strong> Study 1, we learned ways to enhance curriculum,<br />
<strong>in</strong>struction, and measures. For example, whereas teachers<br />
from both sites were concerned with the length of the<br />
<strong>in</strong>tervention, Study 2 teachers were less concerned about<br />
coverage of other topics. Instead, teachers from Study 2<br />
reported the need to reduce what they considered redundancy<br />
<strong>in</strong> the curriculum as well as highly directive <strong>in</strong>struction<br />
because the majority of their students (i.e., average<br />
and high performers) occasionally appeared unmotivated<br />
dur<strong>in</strong>g the <strong>in</strong>structional sessions. Considerable evidence<br />
shows that pac<strong>in</strong>g curriculum and <strong>in</strong>struction to match the<br />
needs of the student is one way to ensure that the needs of<br />
highly able students are addressed (Rogers, 2002).<br />
Attempts to replicate SBI <strong>in</strong> heterogeneous classrooms may<br />
necessitate changes to differentiate the <strong>in</strong>struction for<br />
mixed-ability group<strong>in</strong>gs (e.g., Toml<strong>in</strong>son, 1995).<br />
Our observations <strong>in</strong> Study 2, like those <strong>in</strong> Study 1, <strong>in</strong>dicated<br />
that LO students benefited from the explicit model<strong>in</strong>g,<br />
guided practice, use of schematic diagrams, and checklists<br />
that are characterized by SBI. We observed that LO<br />
students tended to participate more than was typical dur<strong>in</strong>g<br />
SBI <strong>in</strong>struction, and their teachers stated that <strong>in</strong>struction<br />
had clear benefits for them. However, as a group, the performance<br />
of LO students on the three measures was <strong>in</strong>consistent<br />
and highly variable. They performed well on the<br />
WPS-F and computation measure but not on the WPS-<br />
CRT. On the WPS-CRT (pretest: M = 22.00, SD = 11.18;<br />
posttest: M = 19.89, SD = 12.97), performance of LO students<br />
was highly variable, as <strong>in</strong>dicated by large standard<br />
deviations. That result did not occur for the WPS-F<br />
(pretest: M = 12.06, SD = 4.66; posttest: M = 17.67, SD =<br />
8.91) or computation test (pretest: M = 27.00, SD = 4.06;<br />
posttest: M = 29.44, SD = 4.50). The length and difficulty<br />
of the WPS-CRT appeared to affect the performance of the<br />
LO group most directly; variability decreased when the<br />
measures were shorter or less challeng<strong>in</strong>g.<br />
F<strong>in</strong>ally, although the two teachers who participated <strong>in</strong><br />
Study 2 reported that they had few problems implement<strong>in</strong>g<br />
SBI <strong>in</strong>struction and had high levels of treatment fidelity<br />
(M = 98%), <strong>in</strong> h<strong>in</strong>dsight, the teachers may have had more<br />
to reveal had they received our consistent support. Provid<strong>in</strong>g<br />
teachers with more frequent opportunities to converse<br />
with us may have allowed for <strong>in</strong>structional adaptations that<br />
addressed vary<strong>in</strong>g student needs. Instruction that meets the<br />
needs of heterogeneous groups of students is not easily<br />
designed, and, consequently, may require more structured,<br />
collaborative efforts between teachers and researchers.<br />
General Discussion<br />
Design studies have the potential to allow researchers to<br />
develop <strong>in</strong>-depth understand<strong>in</strong>gs of teach<strong>in</strong>g and learn<strong>in</strong>g<br />
<strong>in</strong> classroom environments, that <strong>in</strong> turn, can assist them <strong>in</strong><br />
the design of experimental or quasi-experimental studies<br />
(Gersten et al., 2000). Specific examples of those benefits<br />
<strong>in</strong>clude enhanced knowledge about (a) <strong>in</strong>structional design<br />
features of an <strong>in</strong>tervention, (b) student and teacher<br />
responses to the <strong>in</strong>tervention, (c) measures used, and (d)<br />
the role of the researcher <strong>in</strong> facilitat<strong>in</strong>g the study. Like pilot<br />
studies, design experiments allow researchers to determ<strong>in</strong>e<br />
the feasibility of an experiment before implement<strong>in</strong>g it on<br />
a larger scale and under more carefully controlled conditions<br />
(Gersten, <strong>in</strong> press).<br />
We undoubtedly learned much about SBI for promot<strong>in</strong>g<br />
mathematics word problem solv<strong>in</strong>g by conduct<strong>in</strong>g the two<br />
design studies reported here. Although we may have a few<br />
unanswered questions, neither the knowledge ga<strong>in</strong>ed nor<br />
the uncerta<strong>in</strong>ties revealed would have occurred without<br />
carry<strong>in</strong>g out the <strong>in</strong>vestigative work of these studies. The<br />
most notable <strong>in</strong>sights revealed to us from conversations<br />
with the teachers and from our own observations <strong>in</strong>cluded<br />
the benefits of strategy fad<strong>in</strong>g to promote <strong>in</strong>dependent stu-

dent use of SBI. Encourag<strong>in</strong>g <strong>in</strong>dependent, self-regulated<br />
use of strategies has been supported <strong>in</strong> the read<strong>in</strong>g literature<br />
for years and is perceived as an important long-term goal of<br />
strategy <strong>in</strong>struction (Pressley et al., 1992). We suggest that<br />
support<strong>in</strong>g the <strong>in</strong>dependent use of strategies is an important<br />
aspect of mathematics word problem-solv<strong>in</strong>g <strong>in</strong>struction<br />
as well.<br />
We also realized the need for changes <strong>in</strong> the compare<br />
problem <strong>in</strong>struction by collaborat<strong>in</strong>g first with the teachers<br />
at Site 1, and later with teachers at Site 2. We observed<br />
that the vocabulary words and compare schema diagram<br />
were difficult and confus<strong>in</strong>g for students at all achievement<br />
levels. Hav<strong>in</strong>g the opportunity to alter academic <strong>in</strong>terventions<br />
on the basis of student and teacher <strong>in</strong>put is a powerful<br />
outcome of design studies and will strengthen the<br />
<strong>in</strong>struction when exam<strong>in</strong>ed <strong>in</strong> subsequent studies. We also<br />
learned about the importance of provid<strong>in</strong>g extensive support<br />
to teachers dur<strong>in</strong>g the study implementation. We are<br />
conv<strong>in</strong>ced that the frequent and consistent support provided<br />
to teachers <strong>in</strong> Study 1 allowed their students to perform<br />
better. Alternatively, if we had offered more support <strong>in</strong><br />
Study 2, the teachers may have shared additional comments<br />
with us about the implementation of the study.<br />
Those comments could have prompted changes <strong>in</strong> the<br />
<strong>in</strong>struction, which may have better addressed the academic<br />
needs of the students and improved their performance.<br />
Furthermore, Study 2 helped reveal the complexities of<br />
work<strong>in</strong>g <strong>in</strong> heterogeneously grouped classrooms. With the<br />
strengthened Least Restrictive Environment (LRE) provision<br />
<strong>in</strong> 1997 mandat<strong>in</strong>g that students with disabilities have<br />
access to, and make progress <strong>in</strong>, the general education curriculum<br />
(U.S. Department of Education, 1997), more students<br />
with disabilities may be part of general education<br />
classrooms. Consequently, teachers will be <strong>in</strong>creas<strong>in</strong>gly<br />
challenged to create <strong>in</strong>struction that addresses the needs of<br />
students <strong>in</strong> academically heterogeneous classrooms. The<br />
method of do<strong>in</strong>g that well is still unclear to us. However,<br />
we conjecture that some aspects of SBI will likely benefit<br />
high-, average-, and low-perform<strong>in</strong>g students differentially,<br />
and others may improve their performance as a group.<br />
Low-perform<strong>in</strong>g students <strong>in</strong> both studies most likely benefited<br />
from direct, explicit, and systematic <strong>in</strong>struction.<br />
High-perform<strong>in</strong>g students may have enjoyed the pairedlearn<strong>in</strong>g<br />
opportunities provided dur<strong>in</strong>g SBI. Research that<br />
spans more than a decade suggests that the learn<strong>in</strong>g of<br />
high-achiev<strong>in</strong>g students, such as those <strong>in</strong> Study 2, is facilitated<br />
through peer <strong>in</strong>teraction <strong>in</strong> learn<strong>in</strong>g (e.g., Sw<strong>in</strong>g &<br />
Peterson, 1982; Webb, 1991; Webb, Troper, & Fall, 1995).<br />
The use of schema-based diagrams may have contributed to<br />
the word problem-solv<strong>in</strong>g and computation improvement<br />
among many of the participat<strong>in</strong>g students, regardless of<br />
ability level. Us<strong>in</strong>g what we learned from the design studies<br />
will allow us to strengthen the <strong>in</strong>struction before it is<br />
exam<strong>in</strong>ed <strong>in</strong> future research studies. In the <strong>in</strong>terim, prelim<strong>in</strong>ary<br />
f<strong>in</strong>d<strong>in</strong>gs reveal the potential of SBI <strong>in</strong> mathematics<br />
word problem solv<strong>in</strong>g with third-grade students.<br />
