Leveraging Knowledge Graphs and Large Language Models to Track and Analyze Learning Trajectories

This study addresses the challenges of tracking and analyzing students' learning trajectories, particularly the issue of inadequate knowledge coverage in course assessments. Traditional assessment tools often fail to fully cover course content, leading to imprecise evaluations of student mastery. To tackle this problem, the study proposes a knowledge graph construction method based on large language models (LLMs), which transforms learning materials into structured data and generates personalized learning trajectory graphs by analyzing students' test data. Experimental results demonstrate that the model effectively alerts teachers to potential biases in their exam questions and tracks individual student progress. This system not only enhances the accuracy of learning assessments but also helps teachers provide timely guidance to students who are falling behind, thereby improving overall teaching strategies.
