Nature has retracted a paper that claimed AI had a positive impact on student learning.
The original paper, titled “ The effect of ChatGPT on students’ learning performance, learning perception, and higher-order thinking: insights from a meta-analysis ,” was originally published in May of last year by Jin Wang and Wenxiang Fan of the Hangzhou Normal University in China. It is a meta-analysis, meaning it combines data from 51 research studies published between November 2022 and February 2025 on the effectiveness of ChatGPT in education. The paper claimed it found that ChatGPT had a large or moderately positive impact on “students’ learning performance, learning perception, and higher-order thinking.”
