The Generative AI Learning Penalty: Evidence from Chinese Secondary Education
Using 30 months of panel data on 26,811 Chinese students in grades 7-12, we study how generative AI affects homework productivity and learning. The data combine monthly closed-book exams, high-school and college entrance exams, and homework scores and completion time across nine subjects. We exploit staggered AI adoption in a difference-in-differences design. AI adoption raises homework scores by 18% and reduces completion time by 30%, but lowers monthly exam scores by 20% within six months. High-stakes entrance-exam scores fall by 18 and 24%, with the full penalty emerging only after about two years. The losses are largest in social science subjects, followed by STEM and languages, and are especially large for junior students, high-achieving students, and boys. The learning losses are concentrated among roughly 80% of AI users whose behavior is consistent with homework outsourcing, as indicated by exceptionally short homework completion time coupled with high homework scores. AI users who maintain similar homework completion time as non-AI users experience small learning losses.
Edit: moving my comment up here
Just in case as it’s formatted a bit weirdly
X-Axis: Homework scores
Y-Axis: Exam scores
Yeah sorry. Idk why I commented it
I don’t know why you even posted this in the first place. There’s a “perfect” graph inside the article you could have screenshotted and used instead.
Saved hundreds of people frustration and more data center pollution. Who needs ai slop when humans can be this sloppy.
But you did expose the mob here will upvote anything even if the OP is of piss poor quality.
