ABSTRACT
This study tested the mutual effects of the instructor's eye gaze and facial expression on students’ eye movements (i.e. first fixation time to the slides, percentage dwell time on the slides, and percentage dwell time on the instructor), parasocial interaction, and learning performance in pre-recorded video lectures. Students (N = 118 undergraduate and graduate students) were assigned to watch one of four videos in a 2 (gaze: direct, guided) × 2 (facial expression: surprised, neutral) between-groups design. Contrary to our hypotheses, eye movement data showed that students who watched the video lecture with the instructor's guided gaze and surprised face showed longer first fixation time to the slides and lower dwell time on the slides; these students also had lower learning scores. Instructor eye gaze and facial expression did not influence students’ ratings of parasocial interaction. Our results suggest that in reference to social cues during video lectures with slides, “more” is not necessarily “better.” The findings have practical implications for designing pre-recorded slide-based video lectures: An instructor is cautioned against using multiple social cues simultaneously, especially in video lectures in which the instructor and the visual learning materials compete for students’ attention.
