MATHia X: The Next Generation Cognitive Tutor

MATHia X is the next generation implementation of Carnegie Learning’s Cognitive Tutor (CT), a widely deployed, researchbased mathematics curriculum that has provided data for many educational data mining studies. While many researchers are familiar with the basic operation of the system, there are several features that may affect analysis and interpretation of data that are less well known. We describe features of MATHia X and CT, as well as aspects of its practical implementation in real-world classrooms, that may be important for researchers using MATHia X and CT datasets.
