AI Boosts Homework Scores But Lowers Exam Results?

New research shows that after students use generative AI, homework scores rise by 18%, but exam scores without AI assistance drop by 20%. A 30-month study of 26,000 students found that those relying on AI for homework performed worse on closed-book exams, with negative effects becoming more apparent after two years. Experts warn that AI should be a learning aid, not a shortcut that replaces thinking. Schools need to redesign assessments to ensure students truly master knowledge.
