Dartmouth Course AI Tutor Records 0.71 to 1.30 Standard Deviation Effect Size

AI Tutoring at Dartmouth

A newly developed artificial intelligence tutor has been implemented and tested within a course at Dartmouth College.

Measured Effect Size

The system achieved a notable effect size of 0.71 to 1.30 standard deviations in the course, representing a measurable impact on student performance as documented in a scientific paper.

Whether other academic institutions can replicate these high standard deviation improvements in different subject areas remains the key question for researchers.
