基于VRML的心理学虚拟实验设计与实现

Design and Implementation of VRML-Based Virtual Experiment for Psychology

在远程教育中,学生空间位置相对分散,实验教学大多数采用观看视频的方式进行,学生很少有亲手实验的机会,这使得实验教学的效果大打折扣。VRML技术提供网上的、三维的、可交互的虚拟实验方法,异地的学生能够通过连网的计算机远程亲手做实验。文中介绍了VRML技术特征,并以心理学实验为例,提出了虚拟实验展开的方式。将虚拟实验分为实验准备,交互实验和结果反馈三个阶段,具体介绍了每个阶段要达到的目的、使用的技术和实现的方法。设计的结果达到了教学的目标。

In remote education, students are situated separately. Experiment teaching is almost done by watching video. Students have fewer chances to conduct experiments with own hand. As a result, the educational effectiveness is brought down. By using the technology of VRML, on - line, three - dimensional and interactive virtual experiments can be put into practice. The students in different places can do experiments remotely on computer connected to the internet. This paper introduces the characteristic of VRML and takes psychology experiments as a case, brings forward the ways for conducting virtual experiments. The virtual experiment is purposed to be divided into preparing phase, interacting phase and result feedback phase. The objectives, technologies and means in every phase are described in detail. The result of the designed virtual experiment achieves the goals of teaching.
