What OATutor is

OATutor is an open-source adaptive tutoring system for teachers, researchers, and students. Its practice adapts to learners: Bayesian Knowledge Tracing estimates mastery, then the system adjusts problem difficulty and the amount of practice. Problems are scaffolded into steps, with optional hints and immediate feedback after answers are submitted. The math library focuses on algebra and draws on open-license textbooks, including OpenStax material in algebra, statistics, and calculus.

For research, OATutor includes randomized A/B tests and a Test Mode that can switch off hints, immediate feedback, and mastery updates. Researchers can connect the ChatGPT API to generate dynamic hints, and link survey platforms such as Qualtrics. Canvas integration uses LTI for assignments or modules; its teacher dashboard shows student answers, hints used, and time spent on problems. Interactions can be logged as NoSQL JSON through Firebase and exported to CSV. OATutor is web-based and self-hosted, and can run without a backend server. LMS integration requires middleware. It states that it is Section 508 accessible and provides information about WCAG 2.0 and Section 508 compliance. The software is free and open source.
