An Experimental Bicycle Dissection Exercise was designed in which students perform an abbreviated and slightly altered version of the "Bicycle Dissection Exercise" offered in the Stanford course, "Mechanical Dissection." Like the formal course version of the Exercise, student groups were supplied with a bicycle, tools, a manual, and an assigned set of questions; unlike the formal course Exercise, groups in the Experimental Exercise were also supplied with a multimedia stack that explained (through graphics, text, sound and movies) various aspects of the bicycle. This multimedia stack was created to enrich the dissection experience by providing information and background on the mechanics of bicycles. Three groups of students were videotaped performing this Experimental Bicycle Dissection Exercise. The videotapes were then evaluated by a multidisciplinary group of reviewers using a technique called Video Interaction Analysis (VIA). This paper presents a summary of the experimental assessment process and our findings regarding the educational value of the multimedia courseware in exercises with a handson component.
