Proceedings of the National Academy of Sciences

In a preregistered cluster RCT with nearly 1,000 Turkish high-school students, a standard GPT-4 interface raised assisted practice performance by 48% but reduced later unaided exam performance by 17%. A teacher-informed tutor raised practice performance by 127% and largely removed the penalty without creating a positive exam gain.

ACM Learning @ Scale

Two large randomized trials in ASSISTments found that concise, misconception-targeted LLM feedback improved immediate correction and short-term transfer over correctness-only feedback, with the transfer benefit concentrated among lower-knowledge seventh-grade mathematics students.
