浅谈VRML虚拟实验技术在现代教育技术课程的应用

Discussion on the Application of VRML Virtual Experiment Technology in Modern Educational Technology Course

虚拟实验室是借助网络技术,多媒体技术、V R技术建立的实验系统。虚拟实验室系统的实现模块包括,场景模型,虚拟软件部分,用户界面部分;技术要点包括场景建模,功能设计,用户交互设计。在这个虚拟的实验室里,学生可以自主的控制实验的学习时间和地点,在保证实验效果的基础上,可以很大限度降低建立实验室的难度与实验室资金的投入。作为现代教育技术这门课程实验是其一个重要组成部分,所以开发基于网络的虚拟实验系统并与物理真实实验相结合,能更好的开展实验教学工作。

The study of virtual experiment is beneficial to the smooth progress of classroom teaching, and it also helps students to master the skills of the students. In this virtual lab, students can independently control the time and place of learning, in which based on the experimental results, can greatly minimize the establishment of laboratory and the difficulty of laboratory funds input. As a modem ed- ucational technology course experiment is one of the most important parts, so the development of virtual experiment system of the network and combined with the physical test based on experiment teaching can better carry out the work. Is analyzed in this paper the characteris- tics of the virtual experiment technology and in modem educational technology experiment teaching application, the basic process of anal- ysis and implementation of virtual experiment system, the technical points, and students with the advantages of virtual experimental system for studying.Virtual laboratory is with the aid of network technology, multimedia technology, VR technology to establish experimental sys- tem. Including the implementation of virtual laboratory system module, scene model, virtual software part of the user interface part; Main technical points including the scene modeling, function design, user interaction design. In this virtual lab, the student can be independent control experimental study time and place, in the guarantee on the basis of experimental results, to a large extent reduce the difficulty of the laboratory and laboratory capital investment. As the course for the modem education technology experiment is an important component of the development of virtual experiment system based on network and so combined with physical real experiment, can better carry out the experimental teaching work.
