Abstract: Model tracing and constraint-based modeling are two prominent
paradigms on which intelligent tutoring systems (ITSs) have been based. We
Kodaganallur, Weitz and Rosenthal (2005), have written a paper comparing the
two paradigms, and offering guidance based on this comparison to prospective
authors of ITSs. In a detailed critique of our paper, Mitrovic and Ohlsson
(2006) have taken issue with many of our observations and conclusions. In this
work we refute their critique and provide a more general, critical assessment
of constraint-based modeling.
