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.

逼真的虚拟现实有机化学实验室经验的生产和评估：红外光谱

在教育环境中使用虚拟现实（VR）变得越来越流行。评估了以VR经验替代基于仪器的有机化学实验室的可行性。一个VR实验室的经验旨在教学生如何使用红外光谱仪，并从产生的红外光谱中阐明未知的结构。最终的第一人称VR体验具有身临其境的真实感，并由助教指导用户完成实验所需的步骤，包括根据需要提供的反馈。VR体验是在WondaVR中开发的，使用注视导航进行选择。对一组学生测试了生成的产品，并将短期和长期回忆的结果与在传统实验室中进行相同实验的一组学生进行了比较。结果表明两组之间的学习结果没有显着差异，这表明可以使用此工具通过远程教育提供此有机化学实验室实验。尝试过VR体验的学生表示对产品高度满意，并且没有明显的可用性障碍。这些VR经验对于因残障，出勤挑战（例如怀孕）或安全问题而无法参加实验室的学生可能会很有用。尝试过VR体验的学生表示对产品高度满意，并且没有明显的可用性障碍。这些VR经验对于因残障，出勤挑战（例如怀孕）或安全问题而无法参加实验室的学生可能会很有用。尝试过VR体验的学生表示对产品高度满意，并且没有明显的可用性障碍。这些VR经验对于因残障，出勤挑战（例如怀孕）或安全问题而无法参加实验室的学生可能会很有用。
