An Immersive Hybrid Approach to Materials & Solid Mechanics Lab Activities for Undergrad Students

Abstract

This paper describes two institutions' efforts to provide engineering science students with experiential learning opportunities using low-cost, simple physical lab experiments and its efficacy in improving students perceived understanding levels. A Canadian university developed a "hybrid" lab activity that combined a virtual lab simulator with physical lab experiments to teach materials, solid mechanics, and instrumentation concepts in two different 2nd year undergraduate solid mechanics courses. At a small American college, students in an introduction to materials engineering course completed four individual laboratory exercises using simple and relatively inexpensive material testing setups that explored topics covered in course lectures and readings. Students learned about the behavior of engineering materials and structural analysis using low-cost materials test apparatuses for different loading modes, engaging their senses to aid their understanding. Students then constructed a virtual simulation model using Finite Element Analysis (FEA). Students at both institutions gave positive feedback and reported improved understanding of course topics. The use of low-cost experiments combined with traditional engineering labs shows promise for improving student understanding of engineering science concepts.
