Study Finds Generative AI Boosts Homework Efficiency but Lowers Exam Scores Among Chinese Students

Research involving over 26,000 Chinese secondary students across 30 months reveals that while generative AI use leads to faster homework completion and higher homework scores, it is associated with declines in exam performance, particularly after two years and in social sciences. Experts suggest that reduced engagement time may underlie these effects and recommend educational strategies that emphasize sustained engagement and interactive AI-assisted learning.
