the ai tutor just scored lower than the control group. a university of maryland trial with nearly 2,400 undergraduates found students offered a gpt-4o tutor earned about 4 points less and disengaged, even though most barely used it.
access alone changed their studying.
Context
A University of Maryland randomized trial of 2,379 undergraduates and 30 instructors found that access to a course-integrated GPT-4o tutor reduced final grades by 0.37 standard deviations, per the SSRN paper's abstract, with lower engagement on the course platform.
Inside Higher Ed notes that only about 15 percent of students in the study actually used the tutor.
The trial size, the GPT-4o tutor, lower grades and lower engagement match the paper and coverage. Edtech coverage translates the grade effect to about four points.
'Most barely used it' matches the 15 percent usage reported by Inside Higher Ed.
'Access alone changed their studying' is the author's reading, not a finding in the pages read.
