Innovation and Practical Pathways of Public Art Teaching Mode Driven by Knowledge Graph: A Case Study of Liyang Old Street Project

Under the dual background of New Liberal Arts construction and the Rural Revitalization Strategy, public art education in universities faces the era requirement of reconstructing teaching models to cultivate interdisciplinary practical talents.Addressing the pain point of the theory-practice disconnection in traditional public art courses, this paper introduces the knowledge graph as a core methodology and constructs a closed-loop teaching model driven by a three-stage process: "Theory Construction -Field Empowerment -Outcome Transformation."The research takes the "Children's Poetry Path" project in Ningbo's Liyang Old Street as a practical field, elaborating in detail on the collaborative construction of a knowledge graph by teachers and students, inquiry-based learning and creative generation guided by the graph, and a multi-stakeholder ("Government-University-Village") collaborative evaluation and outcome transformation mechanism.Practice shows that this model effectively enhances students' knowledge integration and application abilities, cultural understanding and innovation capabilities, while providing concrete solutions and intellectual support for local cultural revitalization.Finally, the paper prospects the construction of a digital platform for the knowledge graph, and the policy and mechanism guarantees for model promotion, aiming to provide a referable paradigm for interdisciplinary teaching reform in art and design disciplines.
