摘　　要：Three.js是用JavaScript编写的基于WebGL的在线三维场景和动画的开发引擎。为了使学生能在线开展虚拟仿真实验,探索学生线上自主学习和线下课堂学习相结合的实验教学模式,提升学生实操实验课时的有效利用,采用Three.js提供的JavaScript库函数来开发分光计实验和密立根油滴实验等在线虚拟仿真实验。通过该仿真实验,学生能在实验课之前对实验的原理和操作细节有具体了解,从而对实验中遇到的问题进行深入探究,提高实验教学效果。这些仿真实验也可以作为由于其他原因无法实现线下实验的一种替代教学实验方案。以Three.js为开源开发的物理在线仿真实验平台可推广。Three.js is based on WebGL and written in JavaScript,and is an engine for developing Web browser based 3D scene and animation.In order to make students carry out online virtual simulation experiments,and to create a laboratory teaching mode facilitating the combination of independent online and in-class learning,so that the in-class time of the experiments can be utilized efficiently,we developed a few online virtual experiments of college physics,such as the operation of spectroscope and Millikan’s oil drop experiment,by using the libraries provided by Three.js.It can be expected that students can acquire more intuition and understanding on the experiment principles and operation details from these simulated experiments than simply reading/viewing relevant notes/videos,hence can explore and solve independently more problems encountered in the real experiments.In addition,Three.js is an open-source development platform,so our research can be widely promoted for the development of online simulation experiments.
