Despite the emergence of massive open online courses (MOOCs) and the field of MOOC research, we have a limited understanding of the specific needs of different learner groups and how MOOCs can successfully address those needs. Video lectures and demonstrations are a central learning component of MOOCs. This paper contributes to the research community by examining the use of MOOC videos for two groups of learners. In particular, we explore whether there is an observable difference between specialists' and non-specialists' video-watching activity. We analyse data collected from three MOOCs on the edX platform. Our findings indicate that while age and educational background impacts the level of video activity, there is no significant difference between specialists and non-specialists. We conclude that the MOOC format may be suited to non-specialist groups, allowing them to self-direct their learning and utilise videos as educational resources.
