Students whose tutors used Tutor CoPilot were 4 percentage points more likely to progress through math tutoring session assessments successfully compared to students whose tutors did not have AI assistance, the study found.
The approach particularly benefited lower-rated and less-experienced tutors, researchers said. Students of lower-rated tutors who used the AI assistance increased their math proficiency up to 9 percentage points on average compared to students learning from lower-rated tutors without AI assistance.
The study included 900 tutors and 1,800 elementary and secondary school students from a large school district in the South. Stanford partnered with tutoring company FEV Tutor to pilot the tool’s implementation.
Here’s how it works: A tutor presents a subtraction problem to a student. If the student answers incorrectly, the tutor can activate Tutor CoPilot, which will recommend that the tutor ask the student to identify the numbers in the problem or suggest the student draw the items that need to be subtracted.
