Variable Construction and Causal Discovery for Cognitive Tutor Log Data: Initial Results

چکیده

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.

Toward Cognitive Tutoring in a Collaborative, Web-Based Environment

While intelligent tutoring has been applied to collaborative learning environments, it has met with little success so far because of the complexity involved in adding a tutoring component to a collaborative environment. We propose to tackle this problem by using Cognitive Tutors as the basis for our approach and by applying a technique we call Bootstrapping Novice Data (BND). The BND approach i...

Analysis of a causal modeling approach: a case study with an educational intervention

This paper explores the application of causal models to understanding data generated from a computer tutor. Mily’s World (http://users.wpi.edu/~dovan/coordinates.html) is a flash-based learning environment for coordinate geometry and featuring game-like properties such as a cover story and pictures. We were primarily interested in what class of students benefitted from this type of intervention...
