following: instructional experience, subject matter experience,<br />

computer experience, and cognitive style. Some of this data was<br />

gathered by direct questioning and was easily quantified (e.g.,<br />

number of years of teaching experience). Cognitive style was<br />

determined by questioning and by observation, and was not as<br />

easily quantified. Some aspects of computer experience were<br />

easily determined by questioning (e.g., number of computer<br />

courses taken), but other aspects were not as straightforward<br />

(e.cbI level of expertise with an operating system).<br />

Initial process measures for this soft model included the<br />

following: time spent on an authoring event, sequence chosen for<br />

authoring events, number of revisions attempted and accomplished,<br />

and purpose of revisions. Again some of these processes were<br />

easy to measure and to quantify, but other processes were more<br />

difficult to assess. For example, it was easy to measure how<br />

long an author spent indicating the particular function of a<br />

device that was part of the lesson content. However, determining<br />

the purpose of a particular revision without interrupting the<br />

integrity of the authoring process was more difficult. The only<br />

way to accomplish this was to note that a revision had been made,<br />

look at the revision, if its purpose was not obvious (e.g.,<br />

correcting a misspelled word was an obvious revision), then the<br />

author was asked after the session about the purpose of the<br />

revision.<br />

Initial output measures for this soft model included the<br />

following: total time to produce the lesson module, total cost<br />

to produce the lesson module, student achievement on tests,<br />

retention, student motivation concerning the material, level of<br />

interactivity of the lesson, instructor motivation to use the<br />

authoring environment in the future, and peer review by other<br />

instructional developers. Once again some of these measures are<br />

direct and straightforwardly quantifiable (e.g., total<br />

development time, student scores, etc.), while some are indirect<br />

and more qualitative (e.g., instructor and student motivation).<br />

The initial subject was observed completing a lesson module<br />

to teaching the names, locations, and functions of 125 parts in<br />

the T-37 cockpit. Subject's experience was determined in an<br />

extensive interview prior to the study. Subject's motivation was<br />

observed throughout the study. In addition, the subject was<br />

queried midway through the study concerning his progress and<br />

problems encountered. The subject also kept a diary of authoring<br />

events, including problems encountered and general impressions.<br />

Results<br />

The relevant input measures of the subject were as follows:<br />

1) Medium instructional experience, 2) High subject matter<br />

experience, 3) Low computer experience, and 4) Reflective<br />

cognitive Style with a self-directed locus of control. A formula<br />

for connecting each of these factors with output measures is<br />

currently being developed and will be tested in the second<br />
