What studies of the instructor's face in video found
Ratings and motivation rise with the face on screen. Learning mostly does not.
A summary table of the main evidence on showing the lecturer's face in instructional video: two large field studies by Kizilcec, Bailenson and Gomez (2015), an eye-tracking study by Wang and Antonenko (2017) and a meta-analysis of 20 experiments by Alemdag (2022). It is for quality teams and programme leads deciding how to evaluate or re-record video lectures. Use it to separate how a format feels from what students learn. Koji's follow-up questions ask students why they rated a video format as they did.
What's in this reference table
| Study | Design | Main finding |
|---|---|---|
| Kizilcec et al. 2015, study 1 | 8 weeks, 2,951 online learners chose face or no face | Face viewers rated the experience higher. 35% chose no face |
| Kizilcec et al. 2015, study 2 | 10-week experiment, 12,468 learners, constant vs strategic face | No difference in learning or attrition. Load higher when strategic |
| Wang and Antonenko 2017 | Eye tracking, maths video with or without instructor | More attention and perceived learning. No transfer difference |
| Alemdag 2022 | Meta-analysis of 20 experiments | More motivation and load. No significant learning effect |
