Abstract
In this paper, we investigate the relationship between students’ (N = 28) individual differences and visual attention to pedagogical agents (PAs) during learning with MetaTutor, a hypermedia-based intelligent tutoring systems. We used eye tracking to capture visual attention to the PAs, and our results reveal specific visual attention-related metrics (e.g., fixation rate, longest fixations) that are significantly influenced by learning depending on student achievement goals. Specifically, performance-oriented students learned more with a long longest fixation and a high fixation rate on the PAs, whereas mastery-oriented students learned less with a high fixation rate on the PAs. Our findings contribute to understanding how to design PAs that can better adapt to student achievement goals and visual attention to the PA.

Notes
- 1.
The increase from pretest to post-test is statistically significant indicating that MetaTutor is overall effective at fostering learning, as further discussed in [1].
- 2.
We include each of our six individual differences separately in the analysis to ensure that we do not overfit our models by including all factors at once.
- 3.
We report statistical significance at the .05 level throughout this paper, and effect sizes as small for \( \eta_{\text{P}}^{2} \, \ge \,0.0 2 \), medium for \( \eta_{\text{P}}^{2} \, \ge \,0.13 \), and large for \( \eta_{\text{P}}^{2} \, \ge \,0. 2 6 \).
