Abstract: In response to the problems existing in the current implementation of blended learning, knowledge graph technology is introduced into the teaching system of atomic physics courses to construct a multimodal knowledge graph for atomic physics courses. Based on the course resources of Chaoxing Learning Platform, a blended learning design scheme based on knowledge graph is established from the online self-learning stage, classroom in-depth exploration stage, and post class consolidation and expansion stage. The practical effect of this teaching mode is evaluated based on students'academic performance and teaching satisfaction. Research has shown that the blended learning model that integrates knowledge graphs can effectively stimulate students'learning interest, strengthen their self-learning ability, improve teaching quality and effectiveness, and provide a new research perspective and feasible practical path for the reform of physics courses.
