A critique of Kodaganallur, Weitz and Rosenthal 'A comparison of model-tracing and constraint-based intelligent tutoring paradigms'

摘要

In the following, we group the flaws in the authors' paper into three sections. We first address KWR's misconceptions regarding the constraint representation that is the core of the CBM approach and the suboptimal implementation decisions these misconceptions caused. In the following two sections, we discuss their conclusions with respect to the range of application and remediation. We then critique how they conducted their comparison. We end with some reflections on how this sort of comparison ought to be conducted.
