Vicarious Learning with a Digital Educational Game: Eye-Tracking and Survey-Based Evaluation Approaches

The paper presents an empirical study with a digital educational game (DEG) called 80Days that aims at teaching geographical content. The goal of the study is twofold: (i) investigating the potential of the eye-tracking approach for evaluating DEG; (ii) studying the issue of vicarious learning in the context of DEC. Twenty-four university students were asked to view the videos of playing two micro-missions of 80Days, which varied with regard to the position of the non-player character (NPC) window (i.e. lower right vs. upper left) and the delivery of cognitive hints (i.e. with vs. without) in this text window. Eye movements of the participants were recorded with an eye-tracker. Learning effect and user experience were measured by questionnaires and interviews. Significant differences between the pre- and post-learning assessment tests suggest that observers can benefit from passive viewing of the recorded gameplay. However, the hypotheses that the game versions with cognitive hints and with the NPC window on the upper left corner can induce stronger visual attention and thus better learning effect are refuted.
