The Subject Knowledge Representation and Utilizations in E-Learning

This paper takes knowledge points as key factor in all type of learning process, and any E-learning activity should regard knowledge points as kernel concepts for organizing and extending learning resources. Therefore we suggest the construction of subject knowledge base in E-learning, and provide a universal model to build subject knowledge networks. Besides the purpose to aid E-learning process, subject knowledge base can also be used to realize simple learning navigation by referring to relations of knowledge points, and in this way personalization of learning is possible. In addition, this paper defined a new type of E-learning teaching resource library that internally contains Scorm standards, but externally exhibits semantic structures while distributed as a whole on the Internet.
