摘　　要：在分析多媒体远程教学需求的基础上 ,提出了一种涉及教师T、学生P、课件资源R、协作教学环境E和网上教学管理M等要素的 ,表示远程教学的五元组结构模式 .进一步设计了基于IP网的多媒体远程教学系统的总体框架 ,提出了一种基于Web的、支持按需点播学习和教学现场直播的远程教学系统的实现模型 ,并在校园网上得到了验证 .实验表明 ,该模型及其实现方法是实用可行的 .A 5 tuples (T, P, R, E, M) of the multimedia distance learning system is presented. Here, T refers to teacher, P to pupils, R to the resources and teaching materials of distance learning, E to the cooperative learning environment over IP network and M to the strategies and rules related to the distance learning. Moreover, a general frame of distance learning over IP network is also provided. Finally, an implementation model of distance learning based on Web is designed and verified on the campus Intranet. In this system, pupils can view the lecture sections in real time or review the record on demand. Experiment has shown that this model and its implementation are feasible.
