Research on the knowledge-based e-learning teaching application platform

By constructing a e-learning teaching system of concept network-knowledge framework-learning resource three-layered knowledge model, this paper starts from the basic form and the cognitive structure of knowledge, focuses on the knowledge and resources organizations issues on online education, characterizes the relationship between the knowledge structure and knowledge of the subject areas on the conceptual level, and solves the problem of knowledge dynamic classification. Meanwhile, this three-layered knowledge model also solves the different forms of knowledge organization and appearance problem such as concept, knowledge organization, and learning resource, which puts forward new ideas to the domain knowledge construction of teaching system in the e-learning environment [1,2].
