| Challenge: | Large language models (LLMs) enable scalable content generation for personalized learning, but reliability and pedagogical alignment remain open challenges. |
| Approach: | They propose a web-based system that integrates expert-validated assessment, retrieval-augmented generation (RAG), and an LLM-as-a-Judge validation loop within a closed instructional pipeline. |
| Outcome: | The proposed system achieves a gain of 37.9 percentage points and a large effect size in a real-world deployment with 179 registered users. |
