Abstract: Due to the limited research on university course knowledge graphs, this paper proposes a framework for constructing a material mechanics course knowledge graph based on a semi-automated approach. The framework consists of four main layers: the course layer, knowledge layer, knowledge point layer, and knowledge element layer. The course layer defines the overall concepts and goals, the knowledge layer organizes the course content systematically, the knowledge point layer explains the core concepts of each topic, and the knowledge element layer delves into specific micro-knowledge units. By integrating a blended teaching model with the course knowledge graph, it not only improves teaching efficiency but also fosters students' self-directed learning ability and problem-solving skills in complex engineering tasks, providing a new teaching paradigm for new engineering education.
