Abstract: To address knowledge fragmentation and information silos in constructing knowledge graphs (KGs) for teacher education courses, and to overcome limitations of existing approaches - such as shallow text-based relationship mining, expert-dependent modular design, and weak interpretability between competency objectives and curriculum resources - this study proposes an integrated KG construction and modular design method combining association rule mining (ARM) with an enhanced MetaPath2Vec++ model. A ternary relationship matrix linking curricula, knowledge points, and competencies is first established under teacher professional standards. Strong association rules are then mined via an improved FP-Growth algorithm to generate a weighted association matrix that reinforces semantic links. Finally, a multi-objective optimisation framework integrating modularity and information connectivity dynamically adjusts modules based on competency constraints. Experiments demonstrate improved knowledge density, clearer module boundaries, and stronger cross-module semantic connectivity, enabling adaptive support for teachers' professional development.

Keywords: association rule mining; ARM; knowledge graph; modular design; teacher education curriculum; dynamic structure.
