工科实验课程在构建实践性知识和提高学生技能方面具有重要作用。在电子实验室工作期间，学生们经常操作复杂的实验室设备，通过一套多个旋钮和按钮来配置设备(S)。掌握操作实验室设备的技能需要大量的练习，没有任何经验的学生很难操作这些设备。虚拟现实(VR)是一项新兴技术，有可能为学生提供更好的学习体验。本文开发了一个基于虚拟现实的学习环境，旨在对工科学生进行电子实验硬件的前期培训。本研究旨在探讨虚拟现实技术对学生知识发展、学习动机和认知能力的影响。本研究以65名工科大学生为研究对象，随机分为治疗组(N=33)和对照组(N=32)。治疗组采用虚拟现实教学法，对照组采用常规教学方法。实验结果表明，虚拟现实对学生的知识、学习动机和认知都有显著的积极影响。通过与实验室仪器的三维虚拟模型互动，学生能够展示对实验室硬件的更好理解。此外，治疗组学生提到，他们并不担心设备故障，这进一步增强了他们的信心，减轻了认知负荷。
Engineering laboratory courses have a significant role in building practical knowledge and enhancing the skills of the students. While working in electronics laboratories, students often operate complicated laboratory equipment and juggle through a set of multiple knobs and buttons to configure the equipment(s). It takes a lot of practice to master the skill of operating the laboratory equipment and it becomes difficult for students to operate the equipment without any prior experience. Virtual reality (VR) is the emerging technology and has the potential to provide a better learning experience to the students. In this paper, a VR-based learning environment (VLE) is developed, which aims to give prior training to the engineering students about the electronics laboratory hardware. An experimental study was conducted to measure the effectiveness of VR on student knowledge development, learning motivation, and cognition. The study was conducted among the 65 engineering students and they were randomly divided into two groups: treatment group (N = 33) and control group (N = 32). The students of the treatment group were taught with the VR approach and students of the control group were taught with a conventional teaching approach. The outcomes of the experiment indicate that VR has a significant positive impact on student knowledge, learning motivation, and cognition. By interacting with the three-dimensional virtual models of the laboratory instruments, students were able to demonstrate an improved understanding of the laboratory hardware. Also, the treatment group students mentioned that they were not worried about the equipment malfunction that has further enhanced their confidence and reduced the cognitive load.
