We are researching issues involved in constructing Model Tracing Tutors (MTT) and Constraint Based Cognitive Tutors (CBCT) in the complex domain of Physics homework problem solving.

We are primarily interested in problems for which the student must analyze a problem statement, declare a set of relevant physical variables, write down equations constraining those variables, and then, perhaps, solve those equations for a sought variable when values of the others are given.

We are definitely not interested in exercising "plug and chug" problems, in which there is a straightforward sequence of steps to solve the problem.

Thus the context is much like that of ANDES, the tutoring system developed at the University of Pittsburgh and the U. S. Naval Academy. We are especially interested in concept based problem decomposition and concept-based feedback.

Here are some papers by our group:
