What Comprises a Successful Educational Science YouTube Video? A Five-Thousand User Survey on Viewing Behaviors and Self-Perceived Importance of Various Variables Controlled by Content Creators

Educational videos on digital platforms are an attractive way of learning, especially for the younger generation, as they provide easy, personalizable access to a wide variety of content. Allowing for simplified explanations and visual demonstrations, educational videos are highly suitable for scientific content. With 500 h of video content uploaded per minute, YouTube is the most used user-generated video content platform worldwide. This study provides an initial insight into the elements which influence the perceived quality of educational science videos by viewers, with a special focus on natural science videos. In response to a call for study participants via various German natural science and technology YouTube and Instagram channels, over 5,000 participants between the ages of 9 to 72 (M = 18, SD = 8.78) completed a web questionnaire. The questionnaire focused on the participants’ viewing behaviors and their self-perception of the importance of the content-creator controlled variables.It was found that there are six key elements for a successful educational YouTube video: 1) structure, 2) reliability, 3) quality, 4) community integration, 5) presenter, 6) topic. Based on these elements, a checklist with 17 recommendations for the creation of successful educational videos was developed, serving as a practical guideline for content creators.
