Researchers at Stanford University have introduced Tutor CoPilot, a Human-AI collaborative system designed to significantly improve real-time tutoring quality for students. The system was tested in a large-scale intervention involving 900 tutors and 1,800 K12 students, showing statistically significant positive learning gains. The research, led by R. E. Wang, A. T. Ribeiro, C. D. Robinson, and S. Loeb, demonstrated that math tutors using Tutor CoPilot were significantly more likely to help students master their topics. The study found that the system boosted student mastery by 4%, and by 9% for students with lower-rated tutors. This scalable tool, costing $20 per year, empowers tutors with expert strategies to enhance educational outcomes. The research was conducted in 2024.
