AI textbooks flop without structure

South Korea revoked official status for AI‑powered textbooks after one semester, citing technical bugs, factual errors, and extra work for teachers. Despite ~$1.4 billion in public and private spending, school adoption halved and the books were demoted to optional materials. The outcome suggests content‑centric 'AI textbooks' fail without rigorous pedagogy, verification, and classroom workflow redesign. — It cautions policymakers that successful AI in schools requires structured tutoring models, teacher training, and QA—not just adding AI features to content.
