DubinCore, LOM resource description norm and Sharable Content Object Reference Model (SCORM) standard based on the idea of metadata have solved the sharing problem of static Web resources, by bringing forward description norms of Web resources sharing. However, the modular sharing research of dynamic teaching assistant resources, such as questions and answers database and case database, is almost ignored. And there is module with high coupling degree and resources with low sharing level in the traditional e-learning system. Therefore, in this paper, we adopt the idea of a modular system design based on Web service to design a new resources sharing mechanism, to achieve reusing and sharing of components among different systems, and solve the teaching assistant resources isolated problem caused by the differences from e-learning systems, and finally enhance the sharing of teaching assistant resources.
