Abstract: This article addresses the issue of fragmented knowledge systems in coal chemistry courses and constructs a smart curriculum system that integrates knowledge graphs. By integrating textbooks, industry standards, and scientific research achievements, a three-dimensional knowledge network with 53 core knowledge points and 373 nodes was formed. 264 dynamic and diagnostic teaching resources were developed, and a “four-dimensional connected” knowledge graph model was constructed. Research and practice have shown that knowledge graph technology can effectively promote the construction of knowledge associations in the field of education, achieve precise teaching strategies, and provide replicable paradigms for applied curriculum reform.

Key words: Coal chemistry, Knowledge graph, Curriculum development, Smart curriculum system, Reform in teaching, Evaluation system
