Construction•Driven•Evaluation: Exploration and Practice of Knowledge Graph in Scenario-Based Teaching of "Highway Electromechanical System Integration Technology"

To address the challenges of the complex knowledge system, high system coupling, and the difficulty of intuitively presenting multi-dimensional relationships in traditional teaching for the course "Highway Electromechanical System Integration Technology," this paper employs a structured approach to organize core elements such as toll collection, surveillance, communication subsystems, their equipment interconnections, fault logic, and engineering specifications. This process constructs a knowledge graph with deep semantic relationships. Practical engineering scenarios are utilized to design teaching cases, driving the implementation of a scenario-based teaching model. Simultaneously, a multi-dimensional evaluation system is established to assess teaching effectiveness, validating its impact on enhancing student learning interest, knowledge mastery, and practical capabilities.
