Current Teaching Issues
1Current teaching issues: rapid industry transformation poses challenges for talent training
2“Internet+” background learning model
Students have very strong self-learning abilities, learning time is highly fragmented and lacks a systematic approach
Students’ learning needs to coordinate along two axes: the horizontal axis: the classroom runs through the entire process of student training,
the vertical axis is the knowledge system and abilities of students during their learning process, spanning undergraduate, master’s, and doctoral levels.
Teaching Potential of Knowledge Graph
Visualizing the entire process of teaching and learning, linking static knowledge data with dynamic teaching activity data.
The knowledge graph supports data-driven, goal-oriented personalized learning paths, achieving tailored teaching solutions for each student.

Pathway for knowledge graph teaching applications
The professional knowledge graph is based on courses and course groups, forming a problem-oriented knowledge network
First, establish the knowledge graph for individual courses, which cannot lack courses. After forming individual courses, consider the interrelations between courses, which is the course group, or the professional knowledge graph. How to link them together becomes a challenge.
The difficulty is that teachers only teach a few courses, and few teachers can cover all of the more than 50 courses in a major. Linking this all depends on individual teachers’ efforts, which cannot be promoted or sustained.
With the knowledge graph, the search functionality is enabled.
Construction of Professional Knowledge Graph
1、According to the knowledge graph of the course outline, courses are the first-level attributes, and knowledge points are defined as 5-6 level attributes, and then define teaching objectives and requirements.
2、How to resolve relationships
-
Containment relationship: the relationship of knowledge points at each level
-
Requirements: Are there prerequisites for the course knowledge points?
Application of Professional Knowledge Graph
1、Application of professional knowledge graph on the student side
Helps students better grasp professional knowledge and quickly establish a knowledge framework,
by asking questions, obtaining queries for learning paths of knowledge points, providing students with personalized learning guidance
Continuously enrich the links of teaching resources in the knowledge graph, facilitating targeted self-study for students
2、Application on the teaching side
Systematically organize and present the entire professional course
Supporting: knowledge point deduplication, course reconstruction, course chain construction
Facilitating curriculum reform for course groups, revising training programs, and empowering the curriculum system with AI capabilities
Outlook on Knowledge Graph Teaching Applications
1、Targeting knowledge inheritance and innovation awakening through a teacher-student-machine learning paradigm
2、Using project-based learning
