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.
