网络课程的共享及其实现

Sharing of Online Courses and Its Realization

网络教学资源的共享是一个涉及多种因素的复杂问题，从实践中看，资源共享至少需要以下先决条件：开放的理念、优质的资源、良好的机制和可行的技术方案。目前的进展表明，开放的理念和优质的资源已经有所保障，良好的机制和可行的技术方案成为实现资源共享的关键。本文从网络课程的共享出发，分析了网络课程的共建共享机制，探讨了网络课程共享的两种模式：课程共享模式和课件共享模式，进而论文以课件共享模式为重点，以EMIF架构为原型，设计了课件共享的技术模型，讨论了其实现方法。

The sharing of online resources is very important but complicated. Practice has shown that it entails four preconditions: the spirit of sharing， high quality online resources， a sound mechanism， and a realizable technical solution. With the well development of the first two preconditions， the construction of a sound mechanism and a realizable technical solution become more important. Centered on the sharing of online courses， this article discusses a common mechanism of co─building and sharing， analyzes two sharing models: the model of sharing a whole course and the model of sharing its courseware. Then the author puts forward a technical solution for the model of courseware sharing， and discusses its realization method.
