■基于沉浸式虚拟现实(VR)的实验室演示在STEM教育中获得了吸引力,因为它们可以提供虚拟的实践经验。VR还可以促进体验式和视觉学习以及增强的保留。然而,实现的几个优化,深入分析技术的优势和取舍,需要对STEM教育中现代技术的接受度进行评估,以确保更好地利用基于VR的实验室。
■在这项研究中,我们为生物分子工程实验室开发了基于VR的演示,并使用包含自由回答和基于Likert量表的5点问题的调查评估了其有效性.Insta360Pro2相机和MetaQuest2耳机与真人实验室结合使用。一组53名学生在亲自进行了简短的实验室概述后,在实验室中观看了VR耳机上的实验演示,然后在实验室中进行了实验。
只有28.29%的学生报告在使用先进的VR设备后出现某种形式的不适,而之前的学生中只有63.63%。大约40%的学生报告说,VR消除或减少了来自环境的听觉和视觉干扰。视频的长度是合适的,他们收到了足够的信息来理解任务。
■发现传统的实验室方法更适合解释背景信息和实验室概念,而VR则适合演示实验室程序和任务。分析开放式问题揭示了克服VR与传统学习模式整合的潜在挑战和陷阱的几个因素和建议。这项研究提供了关键见解,以帮助优化沉浸式VR的实施,以有效地补充亲自学习体验。
UNASSIGNED: Immersive virtual reality (VR) based laboratory demonstrations have been gaining traction in STEM education as they can provide virtual hands-on experience. VR can also facilitate experiential and visual learning and enhanced retention. However, several optimizations of the implementation, in-depth analyses of advantages and trade-offs of the technology, and assessment of receptivity of modern techniques in STEM education are required to ensure better utilization of VR-based labs.
UNASSIGNED: In this study, we developed VR-based demonstrations for a biomolecular engineering laboratory and assessed their effectiveness using surveys containing free responses and 5-point Likert scale-based questions. Insta360 Pro2 camera and Meta Quest 2 headsets were used in combination with an in-person lab. A cohort of 53 students watched the experimental demonstration on VR headsets in the lab after a brief lab overview in person and then performed the experiments in the lab.
UNASSIGNED: Only 28.29% of students reported experiencing some form of discomfort after using the advanced VR equipment as opposed to 63.63% of students from the previous cohort. About 40% of the students reported that VR eliminated or reduced auditory and visual distractions from the environment, the length of the videos was appropriate, and they received enough information to understand the tasks.
UNASSIGNED: The traditional lab method was found to be more suitable for explaining background information and lab concepts while the VR was found to be suitable for demonstrating lab procedures and tasks. Analyzing open-ended questions revealed several factors and recommendations to overcome the potential challenges and pitfalls of integrating VR with traditional modes of learning. This study provides key insights to help optimize the implementation of immersive VR to effectively supplement in-person learning experiences.
