Refinement-based student modeling and automated bug library construction

A critical component of model-based intelligent tutoring systems is a mechanism forcapturing the conceptual state of the student, which enables the system to tailor its feedbackto suit individual strengths and weaknesses. To be useful such a modeling technique mustbe practical, in the sense that models are easy to construct, and effective, in the sense thatusing the model actually impacts student learning. This research presents a new studentmodeling technique which can automatically...
