Abstract The comprehensive digital transformation of education has emerged as new track and breakthrough in the development of education in China. large-scale and individualized education has become a new teaching paradigm in the digital age. Knowledge graph, due to its teaching advantages such as visualized knowledge relationships, data-driven pedagogical decision-making, and personalized adaptive learning, has become a crucial lever in the digital transformation of education. This paper, based on the knowledge graph technology of the Chaoxing Fanya platform, proposes a framework for activity-oriented multi-modal knowledge graph construction and outlines five principles for knowledge graph construction. Through a three-step process of “knowledge point organization, knowledge point importing, and relationship connection”, this paper constructs a knowledge graph for the organic chemistry course. On the basis of these works, this article uses the “aldol condensation and claisen condensation reactions” as the example of teaching content, demonstrating how the knowledge graph can be applied to blended learning in organic chemistry. This research provides new insights and practical references for teaching reform in chemistry education based on knowledge graphs.
