Future-Proofing Programmers: Optimal Knowledge Tracing for AI-Assisted Personalized Education
This work addresses the need for scalable and adaptive educational tools for students, though it appears incremental as it builds on existing knowledge tracing methods.
The paper tackles the problem of modeling student learning states for personalized education by proposing CoTutor, an AI-driven model that enhances Bayesian Knowledge Tracing with signal processing and generative AI, resulting in measurable improvements in learning outcomes in university trials.
Learning to learn is becoming a science, driven by the convergence of knowledge tracing, signal processing, and generative AI to model student learning states and optimize education. We propose CoTutor, an AI-driven model that enhances Bayesian Knowledge Tracing with signal processing techniques to improve student progress modeling and deliver adaptive feedback and strategies. Deployed as an AI copilot, CoTutor combines generative AI with adaptive learning technology. In university trials, it has demonstrated measurable improvements in learning outcomes while outperforming conventional educational tools. Our results highlight its potential for AI-driven personalization, scalability, and future opportunities for advancing privacy and ethical considerations in educational technology. Inspired by Richard Hamming's vision of computer-aided 'learning to learn,' CoTutor applies convex optimization and signal processing to automate and scale up learning analytics, while reserving pedagogical judgment for humans, ensuring AI facilitates the process of knowledge tracing while enabling learners to uncover new insights.
