Project-Based Learning Teaching Design and Personalized Learning of “Signal and System” Course Based on Knowledge Graph

To cater to the individualized learning needs of students and enhance the teaching efficacy of the “Signal and System” course, this paper addresses the issues present in the project-based learning (PBL) approach of the course by constructing a knowledge graph for the curriculum. Based on the knowledge graph, a multi-tiered practical project is designed to comprehensively cover the core knowledge points, and students are assisted in utilizing the knowledge graph to achieve autonomous and personalized learning during the project implementation. The application of PBL has significantly improved student performance, validating the effectiveness of the course's project-based instructional design and personalized learning approach grounded in the knowledge graph.
