Using augmented reality to eliminate common misconceptions for students in core mechanical engineering courses

Abstract

An Augmented Reality (AR) tool was designed to address common mistakes and misconceptions that usually stem from poor three-dimensional visualization skills in students in core Mechanical Engineering courses. The AR aid is designed in the form of visual tips that students can see and interact with when looking at a printed exercise though their phone and AR app. This paper also provides the instructions to create these AR tools as well as sample problems that the readers can interact and experiment with. The effectiveness of the approach was verified through comparison of final exam questions on the topic of combined loading in Mechanics of Materials over four semesters with a control class. Significant improvement was observed in elimination of the typical mistakes that stem from visualization. Furthermore, the tool was very easy to initiate by the instructor and students, and generated student enthusiasm and favorable feedback.
