Using Virtual Reality (VR) in educational settings is becoming increasingly popular. The feasibility of replacing an organic chemistry lab with a VR experience has been evaluated, and the user experience has been optimized based on feedback collected form focus groups. A VR laboratory experience was designed to teach students how to use an infrared spectrometer and elucidate an unknown structure from the resulting infrared spectrum. The resulting first-person VR experience is immersive and realistic, with a teaching assistant guiding the user along the steps required to complete the experiment, including feedback as needed. The VR experience was developed in WondaVR with selections made using gaze navigation. The resulting product was tested with a focus group of students and the outcomes for short and long-term recall were compared with a group of students that did the same experiment in a traditional lab. Results indicate that there are no significant differences in learning outcomes between the two groups, which indicates the possibility of using this tool to offer this organic chemistry lab experiment via distance education. Students that tried the VR experience reported a high degree of satisfaction with the product and no significant usability barriers. The experience was optimized based on user feedback to include reviewing capabilities, as well as the option to use on different viewing platforms. These VR experiences could be useful for students who are unable to be present in lab due to disabilities, attendance challenges such as pregnancy, or safety concerns.
