Maryland study: in-class AI cut grades 4pp, only 14.6% of students ever used it
Afinetheorem · x · 2026-10-14
The author unpacks a University of Maryland study on an in-class AI assistant: grades dropped roughly 4 percentage points when students had access to it. Worse, adoption was tiny — only 14.6% ever used the AI, and just 8% (a few dozen students across dozens of courses) asked more than 3 questions. He flags this as bad sign #1, arguing university-built in-class AI tools repeatedly show these bad design patterns, and careful design is essential.
