In response to the challenges of numerous knowledge points and fragmented concepts in the structural chemistry course, as well as the difficulty for students to establish a disciplinary framework and a comprehensive knowledge system, this paper proposed a logical framework and knowledge graph, based on the thematic thread of “Schrödinger equation approximation models – core concepts – simple applications”. This framework includes six branches: particle in box model, single electron hydrogen-like atoms, multi-electron atoms, H₂⁺ molecular, H₂ molecules, and multi-atom molecules. By reconstructing fragmented knowledge and forming a complete knowledge chain, this approach aims to help students understand the logical relationships, generation context and interconnections of important concepts, and provides them with a context for knowledge transfer, ultimately facilitating their understanding and application of knowledge.
