Examining the Interaction of Spatial Visualization Ability and Computer-aided Design and Manufacturing Course PerformanceComputer-aided design and manufacturing (CAD/CAM) tools are ubiquitous in the modernproduct commercialization environment. Students entering this environment will need to be wellskilled in using these tools. One of the key skills associated with both CAD and CAM is spatialvisualization. While several studies have examined the relationship between CAD and spatialvisualization ability, there has been significantly less work investigating visualization ability’srelationship with CAM. A better understanding of the relationship between spatial visualizationability and CAD/CAM course performance as well as the effects of these courses on studentvisualization ability (through pre- and post-tests) could enhance student performance with theseessential tools.This work uses the Revised Purdue Spatial Visualization Tests: Visualization of Rotations(Revised PSVT:R) to assess undergraduate students’ spatial visualization ability. Theparticipants of this study are students who have taken a CAM or CAD course at a largesouthwestern public university. Students’ pre- and post-course spatial visualization data from thetwo courses are compared. In addition, spatial visualization test scores are compared tolaboratory exercise performance metrics and other demographic data.Initial results using partial data showed that on average, students achieved relatively high scoreson the Revised PSVT:R compared to the average scores of first year engineering students in theliterature. While there was a positive correlation between visualization ability and CAD courseperformance, no statistically significant relationship was seen for CAM courses. Neither CADcourses nor CAM courses were seen to increase student spatial visualization ability. However,there was a positive correlation between the number of CAD/CAM courses a student has takenand their spatial visualization ability. As students taking those courses were already juniors orseniors who took similar courses before, their high scores on the Revised PSVT:R implies thattheir spatial ability would already be saturated, meaning little or no room for improvement.
