This Work in Progress paper describes initial findings from an educational innovation project which deploys mixed reality (MR) modules in Engineering instruction. The NSF-funded undertaking is based on findings from a pilot study for chemical engineering completed with institutional resources. Under the NSF grant, we have expanded the scope and have now developed MR assets for both Chemical and Electrical & Computer Engineering instruction. The project research focuses on learning and engagement impacts from use of MR modules in classroom and lab settings for both disciplines.
The Chemical Engineering MR asset is based on the fluid flow in pipes lab, featuring a pipeline network having different pipe diameters, lengths, roughness and fittings. The students will be able to measure pressure drop as a function of fluid flow rate through the different runs of pipe. The Electrical and Computer Engineering MR asset is based on a combination of breadboard, power supply, voltage/amp meter, resistors and circuit connection cables. The students will be able to understand breadboard basics, along with series and parallel concepts and Thevenin, Norton and superposition theorems.
With both MR assets, manipulation, adjustment, and experimentation is possible simulating real world processes and outcomes. Data capture and analysis functions also are present. Students in a Chemical Engineering course and an Electrical and Computer Engineering lab completed two pre- and post-instruction assessments specific to the course topics for which MR assets were used. The first was a short quiz intended to measure learning in the topic and the second was a self-assessment designed to gauge perceived skill in relevant areas. Data analysis consisted of t and Wilcox Wilcoxon tests, as applicable, and constant comparative analysis for theme identification with qualitative input. Findings by course and assessment are discussed with potential implications for Engineering education, grounded in the original literature-based theory.
