Experimental evidence on the learning impact of generative AI: gains persisted when students used it for explanation rather than automation

Zara Contractor, Germán Reyes

arXiv working paper

A randomized, proctored experiment reported that undergraduate access to off-the-shelf generative AI raised immediate factual and conceptual test performance by 0.27 standard deviations and that the gains persisted one week later. The working paper also finds a consequential usage pattern: students who used AI to explain concepts showed stronger delayed gains than students who used it to automate drafting.

ChatGPT's impact on student learning outcomes: a meta-analysis of 35 experimental studies

Xinning Wu, Pei Zhu, Jinliang Zhang, Mengwei Yin, Yingxi Wang

Humanities and Social Sciences Communications

A 2026 meta-analysis of 35 experimental studies and 4,193 participants reported a moderate average positive effect of ChatGPT on learning outcomes, but very high heterogeneity means the pooled result should guide conditional design questions rather than a universal effectiveness claim.
