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.
