Production and Evaluation of a Realistic Immersive Virtual Reality Organic Chemistry Laboratory Experience: Infrared Spectroscopy

Abstract

Using virtual reality (VR) in educational settings is becoming increasingly popular. The feasibility of replacing an instrumentation-based organic chemistry lab with a VR experience has been evaluated. 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 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. 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.

Visualizing molecular structures and shapes: a comparison of virtual reality, computer simulation, and traditional modeling

“…Thus far, the VR simulations have included experiences in 3-D molecular structure, chemical bonding, and intermolecular interactions in molecules (Jiménez, 2019). In their research, Dunnagan et al (2020) evaluated the use of instrumentation in a VR setting and compared it with the use of the real instrument (infrared spectrophotometer) in an organic chemistry lab. The investigation found no significant difference in the learning outcomes between the two groups of students-those that were exposed to the physical instrument and the other group that worked in VR.…”

10 simple rules for supporting a temporary online pivot in higher education

“…Therefore, there is an advantage in including activities relating to experimental design and argumentation of data that are known to improve student outcomes in laboratory work(65) in an online context, as they are beneficial activities that do not actually require physical laboratory work. This approach can be augmented by simulations(66), virtual labs(67,68), or videos(69,70) that develop students' understanding of technical processes relating to laboratory techniques so that the combination of laboratory technique and laboratory process provides an effective overall experience. Many of the strategies for teaching practical skills are also relevant in online environments, such as creating a 'stress-free' safe learning environment, and breaking the skill down into manageable, observable steps(71).…”

Virtual teaching laboratories – hands-on at a distance

“…Including interactivity through email, chat, discussion forums and video calls only go part of the way. More sophisticated strategies based on spatial social platforms, such as Gather [53], SpatialChat [54], and Virtual Reality [7][8][9] show promise of effective engagement as found in our recent experiments in hosting virtual workshops [55]. These workshops were a follow-on activity from our Future of Meetings Symposium [56,57] held last year to explore best practices in remote interactions and focused specifically on delivering engaging workshops to a small, selected audience through the Gather [53] and Glue [58] platforms.…”
