基于空间的计算机支持的协同远程教学系统模型

A Collaborative Distance-learning System Model Based on Space Theory

利用空间模型描述了协同教学系统的特点和组成要素；分析了其过程模式和虚拟教室模型；利用Petri网描述了该系统中用户、异步和同步课程管理模型；设计并实现了相应的系统结构模型。

We categories all the elements in the distance-learning system and describe the model in three space, ie. information space, distribution space and interactive space. User model, Synchronous and Asynchronous course management model are described with Petrinet. Collaborative learning model and virtual classroom model are also analyzed, System structure model based on collaborative work are designed and implemented.
