THE CONSTRUCTION AND APPLICATION RESEARCH OF KNOWLEDGE GRAPH IN MATERIAL MECHANICS COURSE

In view of the limited research on university course knowledge graphs, this paper proposes a framework for constructing a knowledge graph for the material mechanics course via 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 objectives. The knowledge layer systematically organizes the course content. The knowledge point layer elaborates on the core concepts of each topic. The knowledge element layer delves into specific micro-knowledge units. By integrating a blended teaching model with the course knowledge graph, it not only enhances teaching efficiency but also fosters students' self-directed learning ability and problem-solving skills in complex engineering tasks, thus offering a novel teaching paradigm for new engineering education.
