Instructor's direct gaze not body orientation affects learning.

Background: Little is known about the effectiveness of instructors when presenting content in videos alone. In recent years, researchers have increasingly begun to explore the effects of instructors' social cues (e.g., eye gaze, body orientation, etc.) on learning. However, previous studies exploring the effects of eye gaze have confounded the role of body orientation, while studies exploring body orientation have confounded the role of eye gaze. Objectives: To explore the role of direct gaze and body orientation in learning with instructional videos, absent an instructional screen, in a less confounded manner. Methods: A total of 63 subjects were presented select concepts regarding schizophrenia. Eye‐tracking technology combined with current theories of parasocial interaction and social agency was used to explore different social cues that affect learning performance. Students were randomly assigned to one of three experimental conditions: frontal body + direct gaze group (FD group), frontal body + no direct gaze group (FND group), and lateral body + no direct gaze group (LND group). Result and Conclusions: Direct gaze facilitated students' immediate retention and transfer scores, reduced learners' extraneous cognitive load, and guided students' attention to the instructor. However, counter to our expectations, parasocial interaction did not affect social cues. Implications: In both online and offline classes, instruction is expected to be enhanced by focusing on the camera to the extent possible, particularly when instructional screens are absent. Lay Description: What is already known about this topic: In recent years, how instructors' social cues (eye gaze, body orientation, gestures, etc.) can improve video learning has aroused widespread concern.Instructors' eye gaze and body orientation can increase society and improve learning in the online learning environment.The empirical research confounds the role of eye gaze and body orientation on video learning when only the instructors are present. What this paper adds: When only the instructor is present in the video, instructor's direct gaze can foster learner's learning outcome in the instructional video.When only the instructor is present in the video, instructor's direct gaze can draw the learner's attention to the instructor's face.When only the instructor is present in the video, instructor's direct gaze can reduce learner's extraneous cognitive load. Implications for practice and/or policy: In online teaching, educators should consider looking at the camera as much as possible, especially when there are no instructional screens.
