基于有线电视网络的远程教育系统模型及其协同工作的实现

The Model of Synchronous Distance Education System Based on Cable Television Network and Implementation of Supported Cooperative Works

随着现代实时远程教育系统及有线电视网络的应用 ,提高远程教学效果的一个重要而普遍的问题 ,就是在此基础上依据CSCW技术和现代通信技术建立一个实时远程教学系统 ,完成网上实时虚拟课堂、实时同步考试与监督、实时的师生间及学生间的交互 ,使教师和学生自由地共享一个网络提供的集成环境 ,应用有线电视网络数字视频广播系统DVB ,解决非同时学习的协同工作等问题 ,改进和完善远程教育系统。

According to the application of recent synchronous distance education system and cable television network, An important and common problem, which can help us to improve distance tuition effect, is to create and actualize a synchronous distance education system according to the CSCW technology and modern communication technology based on this. We can achieve the synchronous virtual classroom,synchronous examination and supervision,the information exchange between teacher and students or between students each other, and also make teacher and students pool freely a same integrated environment provided by network.We can use the Digital Video Broadcasting based on Cable Television Network to solve the problems of the no same time beginning studies in supported cooperative work, to reform and perfect the distance education system.
