AI-Powered Personalized Learning Path Recommendation
The rapid development of artificial intelligence is reshaping learning concepts and instructional practices. Online learning overcomes temporal and spatial constraints, providing flexible and autonomous learning environments, and has become a central component of educational digitalization. However, the physical separation of teachers and learners makes it difficult to monitor learning progress effectively, while the abundance of learning resources often leads to learner disorientation and reduced learning efficiency. Consequently, effective planning of personalized learning paths is essential for reducing learning costs and improving learning outcomes. Traditional one-size-fits-all instructional models are insufficient to meet learners' needs. In this context, designing transparent, adaptive, and personalized learning paths for individual learners has become an urgent research challenge. This study presents a comprehensive review of personalized learning path recommendation based on knowledge graphs. It analyzes existing methods from interdisciplinary perspectives, with particular emphasis on the theoretical role of Bloom's taxonomy in guiding the design of learning paths. The review further summarizes core algorithm approaches, examines the characteristics and applicability of commonly used public datasets, and identifies major limitations and challenges in current research. Finally, it outlines future research directions aimed at enhancing transparency, adaptability, and explainability to support educational digital transformation and the realization of individualized instruction.

Challenges
Knowledge Graph as Core Infrastructure
Impact: Knowledge graphs explicitly model knowledge concepts, course units, and their interrelationships, forming a crucial infrastructure for structured, explainable learning path recommendation systems. This allows for semantic search and personalized resource discovery.
Benefit: Improves the relevance and pedagogical coherence of recommended learning paths by encoding prerequisite relationships, difficulty levels, and diverse semantic associations among knowledge points.
Integration of Bloom's Taxonomy
Impact: Bloom's Taxonomy categorizes cognitive processes (remember, understand, apply, analyze, evaluate, create), providing a scientific foundation for designing and assessing learning objectives. When integrated with knowledge graphs, it guides the generation of learning paths that align with cognitive development.
Benefit: Enhances pedagogical validity and explainability by ensuring that learning activities progress from lower-order to higher-order thinking, supporting a more natural and effective learning trajectory.

Comparison of Learning Path Generation Methods
| Method Category | Key Characteristics | Enterprise Application Benefits |
|---|---|---|
| Education Theory-Driven | Strong pedagogical foundation, rule-based constraints (e.g., Bloom's Taxonomy), good explainability. | Ensures strong alignment with educational objectives and curricula, high trust from educators. Ideal for highly regulated or specialized training programs. |
| Data-Driven (EDM) | Leverages learners' behavioral data, dynamic adjustments, often uses ML/DL for patterns. | Highly personalized and adaptive to individual learner progress. Excellent for large-scale online platforms with rich interaction data. |
| Mixed Methods | Combines theory-driven constraints with data-driven modeling; balances pedagogical soundness and adaptability. | Offers a robust trade-off between explainability and performance. Suitable for complex learning environments requiring both structure and flexibility. |
Challenge: Dynamic Knowledge Graph Updates
Problem: Educational content constantly evolves, requiring timely updates to knowledge graphs. Manual updates are costly and inefficient, while automatic mechanisms are underdeveloped.
Impact: Outdated knowledge graphs lead to recommendations that deviate from actual instructional needs, reducing effectiveness and learner engagement.
Solution Direction: Implement AI-driven, semi-automated pipelines for knowledge graph construction and continuous updates, leveraging NLP and expert validation to balance efficiency and semantic quality.
Challenge: Explainability vs. Efficiency
Problem: Balancing clear, pedagogically meaningful explanations with algorithm efficiency and recommendation quality is difficult. "Black box" models are efficient but lack transparency; overly detailed explanations can increase computational overhead.
Impact: Without sufficient explainability, learners and teachers may distrust recommendations, hindering adoption. Over-complexity reduces system scalability and real-time responsiveness.
Solution Direction: Develop hybrid explanation mechanisms combining rule-based rationales with attention-based visualizations, focusing on "why" a path is recommended in an interpretable format, while optimizing underlying algorithms for performance.
