Researchers at Stanford University Introduce Tutor CoPilot: A Human-AI Collaborative System that Significantly Improves Real-Time Tutoring Quality for Students

Integrating Artificial Intelligence (AI) tools in education has shown great potential to enhance teaching methods and learning experiences, especially where access to experienced educators is limited. One prominent AI-based approach is using Language Models (LMs) to support tutors in real time. Such systems can provide expert-like suggestions that help tutors improve student engagement and performance. By equipping novice educators with real-time guidance, AI tools have the potential to bridge the expertise gap in education and create a more equitable learning environment. This is particularly crucial in classrooms with diverse student abilities and educational backgrounds.

The fundamental problem in education is the high cost and limited scalability of traditional tutoring training programs. Comprehensive professional development sessions can cost up to $3,300 per teacher annually, making it challenging for schools with tight budgets to offer quality training. These programs often require tutors to invest significant time outside their teaching hours, making them impractical for part-time educators. Also, many professional development programs need to be aligned with the specific needs of novice tutors, which means they fail to address the dynamic, real-time challenges faced during live tutoring sessions. Consequently, many tutors develop their skills on the job, leading to inconsistent teaching quality and missed student learning opportunities.

Educators have relied on professional development workshops and training seminars to improve their skills. However, these methods are not always effective due to their static nature, which doesn’t cater to the real-time interaction needs of teachers. To address this, some educators have tried using online forums and support networks, but these lack the structured feedback necessary for professional growth. Also, adapting generic training programs for specific educational settings remains challenging, and many tutors, particularly those working in under-served communities, find it difficult to implement these strategies effectively.

Researchers from Stanford University developed Tutor CoPilot, a human-AI collaborative system designed to provide real-time guidance to tutors during live tutoring sessions. Tutor CoPilot aims to replicate expert educators’ decision-making process by providing actionable and context-specific expert-like suggestions. The system uses think-aloud protocols captured from experienced tutors to train the AI model to deliver feedback in real-time. This innovative approach enables less experienced tutors to deliver high-quality instruction that closely aligns with best practices in teaching.

Tutor CoPilot works by embedding itself within a virtual tutoring platform, where tutors can activate it during sessions for immediate assistance. The AI system then analyzes the conversation context and the lesson topic to offer suggestions that the tutor can implement instantly. Suggestions include asking guiding questions to encourage student reasoning, providing hints to support problem-solving, and affirming correct responses. Tutor CoPilot allows tutors to personalize these suggestions, making it comfortable to adapt to the unique needs of each student. The platform also includes a safety mechanism that de-identifies student and tutor names, ensuring user privacy during interactions.

The performance of Tutor CoPilot was tested in a large-scale, randomized, controlled trial involving 900 tutors and 1,800 students from Title I schools. The results were significant: students working with tutors who used Tutor CoPilot were four percentage points more likely to master mathematics topics than the control group, where only 62% of students achieved mastery. Interestingly, the positive impact was even greater for tutors initially rated less effective. For these tutors, the mastery rate increased by nine percentage points, closing the gap between less experienced and more experienced educators. The study also found that Tutor CoPilot costs only $20 per tutor annually, making it a cost-effective alternative to traditional training programs.

Key findings revealed that Tutor CoPilot frequently encouraged tutors to employ high-quality pedagogical strategies. For example, tutors using the system were more likely to prompt students to explain their reasoning, use guiding questions to promote deeper understanding and avoid simply giving away the answers. Such strategies are aligned with best practices in effective teaching and have been shown to improve student outcomes significantly. Also, interviews with tutors indicated that they found the system helpful in breaking down complex concepts. However, occasional issues with the tool provided suggestions that needed grade-level appropriateness.

Key Takeaways from the research on Tutor CoPilot:

• The study involved 900 tutors and 1,800 K-12 students from under-served communities.
• Students working with Tutor CoPilot were four percentage points more likely to achieve topic mastery.
• Tutors rated as less effective showed the most improvement, with their students’ mastery rates increasing by nine percentage points.
• Tutor CoPilot costs only $20 per tutor annually, compared to traditional training programs, which cost over $3,300 per teacher.
• The system encourages using high-quality teaching strategies, such as prompting students to explain their reasoning and asking guiding questions.

In conclusion, the study’s results show that integrating human-AI collaborative systems like Tutor CoPilot in education can significantly improve the quality of teaching, particularly in underserved communities. The research team demonstrated that Tutor CoPilot enhances novice tutors’ effectiveness and provides a scalable solution for improving educational outcomes across diverse student populations. At a fraction of the cost of traditional training programs, Tutor CoPilot offers a promising pathway for making high-quality education accessible to all students.
