虚拟现实在大学物理实验教学中应用的探索与实践

Exploration and Practice on the Application of Virtual Reality in College Physics Experimental Teaching

虚拟现实技术(Virtual Reality,简称VR)具有实时性、交互性、易扩充、不受空间限制等优点,为高校物理实验教学改革提供了一种新的思路,它能够很好地解决传统物理实验教学中存在的贵重物理仪器做不到、危险源实验不敢做、仪器损坏率高、仪器更新慢、实验原理抽象难理解等问题.采用VR和传统实验结合的混合教学模式,通过控制变量方式对受试学生进行分组调研分析,结果显示通过VR课前预习后进行仪器操作,实验仪器损坏率明显降低,学生可选实验增加后,明显提升学生学习兴趣,激发学生求知探索欲,同时学生实验课后测试成绩显著提高.

Virtual reality technology has the advantages of real-time,in teractivity,easy expansion,and freedom from space constraints.It provides a new approach for the reform of physics experiment teaching in universities.It can effectively solve the pro blems in traditional physics experiment teaching,such as the inability to access valua ble physical instruments,the ina bility to conduct hazdrd source experi m ents,high instrum ent da mage rates,slow instrument updates,and difficulty in understanding a bstract experimental principles.This article adopts a teaching mode that com bines VR and traditional experiments,and conducts group research and analysis on the test students by controlling varia bles.The results show that through VR pre class preview and in strument operation,the damage rate of experim en tal instruments is significantly reduced.After the addition of optional experimen ts,students'interest in learning is significantly im proved and their desire for knowledge and exploration is stimulated.At the same time,students'test scores after experimen tal classes are significantly im proved.
