Abstract: This paper describes the student modeler of the GUIDON2
tutor, which understands plans by a dual search strategy. It
first produces multiple predictions of student behavior by a
model-driven simulation of the expert. Focused, data-driven
searches then explain incongruities. By supplementing each
other, these methods lead to an efficient and robust plan
understander for a complex domain.
