Abstract

This paper presents a knowledge graph-enhanced recommendation system, inspired by constructivist principles, to address challenges like information overload and fragmented knowledge in online education. The system transforms unstructured information into interconnected knowledge frameworks, facilitating semantic comprehension, personalized recommendations, and cognitive feedback. Aligned with constructivist principles, the platform encourages students to actively construct personalized knowledge structures, enhancing cognitive engagement through adaptive feedback. Experiments with higher education students demonstrate its potential to improve learning interest, knowledge retention, and adaptive feedback, supporting advanced semantic and cognitive learning paradigms.
