CODE-GEN: A Human-in-the-Loop RAG-Based Agentic AI System for Multiple-Choice Question Generation
Researchers developed CODE-GEN, a human-in-the-loop AI system that uses retrieval-augmented generation to create multiple-choice programming questions for educational purposes. The system achieved 79.9% to 98.6% success rates across seven pedagogical dimensions when evaluated by subject-matter experts, demonstrating strong performance in computational verification tasks while still requiring human expertise for complex instructional design.
