Dual Eye Tracking as a Tool to Assess Collaboration

In working towards unraveling the mechanisms of productive collab- orative learning, dual eye tracking, a method where two people's eyes are tracked as they collaborate on a task, is a potentially helpful tool to identify moments when students are collaborating effectively. However, we are only beginning to understand how eye gaze relates to effective collaborative learning and how it fits in with other data streams. In this paper, we present three broad areas of analysis where we believe dual eye tracking will promote our under- standing of collaborative learning. These areas are: (a) How eye gaze is associ- ated with other communication measures, (b) how eye gaze is associated with task features, and (c) how eye gaze relates to learning outcomes. We present exploratory analyses in each of the three areas using a dataset of 28 4 th and 5 th grade dyads working on an Intelligent Tutoring System for fractions. Our anal- yses illustrate how dual eye tracking could be used in conjunction with other data streams to assess collaborative learning.
