Research on the teaching model of knowledge graph for professional introduction course based on OBE

In view of the problems of the current professional introduction course, such as wide scope of knowledge, lack of in-depth knowledge explanation and weak relevance of each course content, this paper proposes a knowledge graph teaching model of professional introduction course based on OBE method. Taking the professional introduction course of "Introduction to the Internet of Things" as an example, we firstly construct the visual course knowledge graph according to the course content arrangement. Secondly, based on the OBE method, we design a set of knowledge graph teaching mode framework. Then, we adopt the knowledge graph completion algorithm based on transE to further complete the course knowledge graph according to the update and change of the content of the major system and the periodic feedback needs of students. Finally, with simulation experiments used, we verify the feasibility of the proposed method, and the actual teaching practice results show that the curriculum knowledge graph can effectively assist teachers to teach professional introduction courses and promote students to systematically master the relevant knowledge system required to learn the major, so as to improve the teaching effect.
