A cognitive tutor is a kind of intelligent tutoring system that allows students to enter multiple steps leading up to the solution of a problem, provides immediate feedback after each step, and upon student request, provides context-sensitive instruction or hints toward reasonable next steps.
Cognitive tutors contain a cognitive model of student thinking (a model of the required knowledge components and use algorithms called model tracing and knowledge tracing to provide tutoring that is personalized for each learner. Knowledge tracing is a method for providing optimized scheduling.
