In this article the authors examine whether there is a relation between the duration of videos and the number of ‘Likes’ they receive. The authors also explore the effect of other observed characteristics of the videos, such as gender of the teacher, type of institution, whether the teacher appears on the screen or not and the type of technology. The authors found that users prefer short online teaching videos. They also found that some features of the videos have a significant impact on the number of ‘likes’. It was found that videos recorded by female teachers, and presented by entities other than universities are more likely to receive ‘Likes’.
