协同远程教学系统的子空间模型与实现

A COOPERATIVE DISTANCE LEARNING SYSTEM MODEL AND ITS IMPLEMENTATION

现代远程教育模式实际上是一种计算机支持的协同工作(CSCW)模式下的应用。新一代的远程教学管理和课程发布模式,必须具有提供强大的自主学习、异步协作和实时学习的课程发布能力,具有开放性、信息共享性、自动化支持、工作协同性、分布性、群体感知等特点。根据协同远程教学系统的基本要求,本文利用一种子空间组合模型从语义上描述了系统组成要素和结构;研究了协同教学系统中用户和课程管理模型;分析了协同教学的过程模式和虚拟教室模型;设计并实现了相应的系统结构模型。

In this paper, we come up with a structure and implementation model of a distance - learning system based on CSCW. We categorize all the elements in the distance - learning system and describe the model in three space: information space, distribution space, interative space. User model,synchronous and asynchronous course management model are described. Collaborative learning model and virtual classroom model are analysed, and system structure model based on collaborative work is also designed and implemented.
