Under the background of the development of emerging engineering disciplines and the digital transformation of education, the curriculum reform of “Fundamentals of Circuit Analysis” has become an urgent priority. Focusing on the application of knowledge graphs in this curriculum reform, this paper conducts an in-depth analysis of its enabling pathways. By sorting out the curriculum’s knowledge system, integrating interdisciplinary knowledge, and constructing multi-dimensional knowledge graphs, the structured and interconnected presentation of knowledge is achieved. Leveraging knowledge graphs to optimize the organization of teaching resources, implement blended teaching, promote personalized learning, and improve the intelligent evaluation system, the transformation of the teaching model from “knowledge point indoctrination” to “competence-oriented” is realized. This provides a theoretical basis and practical plan for cultivating compound engineering talents with interdisciplinary thinking and practical abilities.
