What they did and found
Across thousands of sessions, artificial intelligence tutoring produced Graduate Record Examination score gains similar to expert human tutors, with some AI tools matching or beating humans in certain topics, while cutting cost per point gained.
Why it matters
This could let schools offer more affordable, personalized help, but results vary by subject and not every learner will see the same gains.
In the study, one AI tutor reached gains close to a human tutor in several Graduate Record Examination areas. Overall, AI tutoring showed gains similar to humans.
The finding depends on the tasks tested and hour tutoring window; lower cost stands out, but tutor choice and response time affected engagement and results.
