Undergraduate lab sessions play a crucial role in building and reinforcing conceptual understanding in STEM education. In third and fourth year higher education, lab sessions can be challenging to incorporate into the curriculum due to cost, safety, or difficulty in realizing abstract concepts. Mixed reality (MR) systems provide a novel solution due to their ability to nurture collaboration and tactile interaction. In this work, an MR system designed for use in chemical kinetics undergraduate curriculum is described. This system combines the principles of student-driven, investigative learning with tactile feedback and simulation-based teaching. A small-scale study was conducted to explore students' use of a prototype MR system as compared to a traditional "pen-and-paper" cooperative learning activity. Differences in student engagement and learning outcomes were analyzed. Results indicate that students working with MR demonstrated slightly more accurate and nuanced conceptual understandings, conducted faster and more cycles of inquiry, expressed more clarity when articulating thoughts, and engaged in less risk aversion when presenting their ideas as compared to their peers in the control condition.
