Variable Construction and Causal Discovery for Cognitive Tutor Log Data: Initial Results.
Stephen E. Fancsali · Educational Data Mining · 2012
We present a method to simultaneously search for student-level variables constructed from Cognitive Tutor log data and graphical causal models. We seek causal explanations of behavior in Cognitive Tutors, including “gaming the system” and off-task behavior, selecting variables by their contribution to causal structure and strength learning.
