Virtual Reality in Education to Enable Active Learning and Hands-on Experience

Teaching technical contents related to product design and 3D modeling is a challenging task. Students enrolled in Master of Science courses often have different backgrounds and technical skills, due to their different educational paths at the bachelor’s degree. From the student’s perspective, one of the main difficulties concerns the definition of the 3D modeling procedure, understand technical drawings and figuring out the proper assembly sequence to get the final product. Over the years, some methods to fill these existing gaps have been experimented, such as tutoring and Massive Open Online Courses. Despite these passive approaches have been proven useful for students, digital technologies, such as Virtual Reality, can boost the implementation active learning sessions and hands-on experiences. In this paper, we present a Virtual Reality application for active learning developed to help students in the initial stage of the “Methods and tools for detailed design” course to acquire a set of lacking knowledge, which includes technical terminology related to mechanical parts and components, the ability to decompose mechanical systems into sub-parts, and to create a 3D model using a CAD tool given a 2D engineering drawing. To evaluate the effectiveness of the proposed approach, the application has been tested with a cohort of students with different backgrounds and knowledge about mechanical design and CAD.
