Research on Curriculum Content Reconstruction and Teaching Practice of Communication Electronic Circuits Based on Knowledge Graph

Abstract

The general attributes of the knowledge system for the Communication Electronic Circuit course are dense concepts and complex logical associations. The traditional linear chapter structure cannot show all the connections among the knowledge points, and the speed of content updates is slow in the face of changes in technology. Knowledge graph technology is used to organise the courses in a new way; an ontology model is employed to build a hierarchy of subject knowledge, extract semantic relationships among knowledge points, integrate various teaching materials from different places, and construct a computable and navigable course knowledge graph. Then, it will organise the modules and topology of the knowledge system, design cross-chapter integration paths, and plan navigation sequences according to the cognitive logic. A teaching form based on knowledge graphs can dynamically generate course materials, show how knowledge is connected, and adjust the cognitive load of learners according to the structure of the graph. Course reconstruction based on knowledge graphs can organise the knowledge in the system more rationally, improve the adaptability of courses to changes in the curriculum, and provide systematic support for differentiated instruction.
