实时远程教育系统模型的特性与实现

Characteristics and Implementation of Synchronous Distance Education System Model

随着基于Internet和3层客户/服务器模式体系结构的现代远程教育系统的进一步发展,学员随时随地接受多项远程教育服务(阅读资料,提问解答等)成为现实。然而,提高远程教学效果的另一个关键性问题,就是在此基础上依据CSCW技术和现代多媒体通讯技术建立1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1个网络提供的集成环境,改进和完善远程教育系统。

According to the recent development of modern distance education system, which is based on the Internet and the architecture of 3-layer Client /Server, it becomes reality to make the students accept more services of distance education ( reading information , asking and answering etc. ) in any time and any place. However, another key problem, which can help us to improve the distance tuition effect, is to create and actualize a synchronous distance education system according to the CSCW technology and modern multimedia 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, we can also make teacher and students pool fr.eely a same integrated environment provided by network to reform and perfect the distance education system.
