Impact of Optional Supplemental Course to Enhance Spatial Visualization Skills in First-Year Engineering StudentsThe impact of spatial visualization skills on retention and performance in undergraduateengineering schools has been studied extensively. The National Science Foundation funded afive-year program called “Engaging Students in Engineering” or ENGAGE. One strategy inENGAGE to increase retention and GPA in freshman engineering students is to improvestudents’ spatial visualization skills. With this goal in mind, we have developed an optional one-credit hour non-graded spatial visualization skills intervention course which is offered toincoming freshman engineering students based on their performance on the Purdue SpatialVisualization Test: Rotations (PVST:R). We are now assessing the impact of this course onstudent visualization skills and asking the question “Can an optional one-credit hour spatialvisualization intervention class be used as an effective instructional tool that enables students toenhance their spatial visualization skills?”The research design is an experimental design with control and treatment groups where thetreatment group, which scores an 18 or below on the PVST:R which is taken by all enteringengineering students at summer orientation, opts to takes the intervention course. Theintervention course is a 1-credit hour non-graded visualization intervention class that offers anadditional representation of objects to be depicted in assigned engineering graphics drawingproblems. The control group are the students who score an 18 or below on the PVST:R but optout of taking the intervention course and enroll directly in the first-year engineering courses.Assessments include either a follow-up PVST:R or graphics mid-term score depending uponwhich first-year track students enroll. To date the intervention class has been given toapproximately 180 students while being offered to 358 engineering students who qualified. Thisstudy is currently in progress for its second year but will be completed at the end of the Fall 2013academic term. Based on the literature, we hypothesize that students who take the interventionclass will perform better in their first-year engineering classes as well as overall academicallywhen compared to the control group. No major conclusions can be drawn until the completion ofthe study.
