What OATutor is
OATutor is a free, open-source adaptive tutoring system for personalized learning and Intelligent Tutoring Systems research. Bayesian Knowledge Tracing estimates each learner’s mastery, then adjusts practice difficulty and quantity. Its scaffolding breaks complex problems into steps, offers hints on request, and gives immediate feedback after answers. The math library focuses on algebra and includes material based on open-license OpenStax texts covering algebra, statistics, and calculus. Teachers, researchers, and students are the stated audience. Researchers can run randomized A/B tests or use Test Mode to disable hints, immediate feedback, and mastery updates. ChatGPT API integration can provide dynamic hints. Canvas integration uses LTI for assignments or modules, and survey platforms such as Qualtrics can connect. A Canvas dashboard shows answers, hints used, and time spent. Interactions can be logged as NoSQL JSON through Firebase and exported to CSV. Deployment can run without a backend server, though LMS integration requires middleware.
