RAG (Retrieval-Augmented Generation) — an AI architecture that combines information retrieval with text generation, allowing LLMs to ground responses in external knowledge sources rather than relying solely on training data. In education, RAG addresses hallucination, enables curriculum-grounded tutoring, and powers domain-specific AI tutors.
How RAG is used in education
Hallucination reduction: EduGuard and EduZone use RAG to keep AI tutor responses grounded in verified educational content, reducing Hallucination Risk.Curriculum-grounded tutoring: KITE retrieves relevant curriculum materials to inform tutoring responses, ensuring alignment with course content.Textbook and materials indexing: Synthetic textbook organization indexes educational content for retrieval. StructRAG extends retrieval to structured diagrams.Training pipeline integration: Pedagogical LLM training uses RAG to ground tutor training in educational best practices.RAG vs fine-tuning
RAG serves a complementary role to LLM fine-tuning — retrieval provides up-to-date, domain-specific grounding without retraining, while fine-tuning embeds pedagogical behaviors. The wiki's research explores both approaches and their combination.
Connections
RAG connects to LLM (the generation component), Knowledge Graph (structured knowledge for retrieval), Hallucination Risk (the primary problem RAG addresses), and Edtech Platform (RAG powers production educational systems).
