An Examination of the Effects of Contextual Computer-aided Design Exercises on Student Modeling PerformanceMany in the academe and industry have long found computer-aided design (CAD) educationlacking. These critics have decried the lack of strategic skills and the focus on declarativeknowledge associated with specific CAD packages. This work will discuss the most recentfindings of a three year iterative investigation examining the role of contextual exercises on CADmodeling procedure and the manifestation of adaptive expertise. The effects of a varying numberof contextual exercises incorporated in regular instruction throughout a semester will beexamined. Contextual exercises consist of students modeling a component that they have apersonal connection to, as opposed to a stylized example from the textbook. Modelingperformance on a standard assessment will be compared for the various groups as willperformance on an end of the semester exercise.This work will compare the results of student performance on the standard assessment based onwhether students received no, one, or four contextual exercises prior to the assessment. Studentperformance on an end of the semester exercise that is either stylized or contextual in nature willalso be examined. Student interviews and coding will be used to examine the manifestation ofadaptive expertise among those various groups. Statistical analyses will be used to evaluate anydifferences among the groups, and results will be placed in the context of the wider project. Twocampuses in Southern US collaborate in the wider project that is funded by the National ScienceFoundation.
