Innovative Practice of Data Structure Teaching by Knowledge Graph+AI Q&A+Visualization

In the construction of "new engineering courses", the teaching reform of Data Structure faces the dual challenges of improving the complexity of algorithm and talent training, and there are problems such as insufficient integration of Ideological and political education and scattered visualization applications. Based on Knowledge Graph (KG), this study integrates AI Q&A and process recording to build a teaching model of "intelligent guidance interactive learning dynamic feedback". Display abstract knowledge through KG, use AI Q&A to answer questions at any time and push resources, visualize and cover learning behavior and knowledge graphics. Practice shows that the "KG+AI question and answer+visualization" strategy can stimulate students' interest, improve knowledge organization ability and achievement, and effectively promote teaching optimization, which is of great promotion value.
