Virtual Reality’s Role in Improving Student Knowledge and Engagement in the Materials Testing Laboratory

Abstract

The aim of this work was to evaluate the efficacy of using virtual reality (VR) to develop training modules for students in mechanical engineering laboratory classes. Specifically, we investigated the feasibility of applying VR in material testing labs to increase engagement and learning outcomes and also in fostering more effective use of expensive lab equipment. To validate the VR software and test our hypotheses, we conducted pilot testing at Texas A&M University. A two-group, randomized control trial was conducted with 118 students. Results of the pilot test suggest an overall positive outcome for students participating in the VR virtual lab first (experimental condition) compared to those who performed the physical lab first (control condition). Students in experimental condition scored significantly higher on both multiple-choice and open-ended subject matter questions. Subgroup analysis indicated that females in the experimental group gained twice as much as males.
