Learners in MOOCs often experience challenges that can be identified as barriers to learning. These barriers may be MOOC- or not MOOC-related. By knowing about potential barriers learners would be better prepared and more likely to handle and overcome them. Therefore, the aim of this study was to advance insight and knowledge about barriers to learning in MOOCs. Assessment and reassessment of the data using exploratory factor analysis provided a good model fit for a 6-factor structure. This was confirmed by a confirmatory factor analysis. Further classification of the factors revealed that barriers experienced by learners were predominantly non-MOOC related. To get insight into the barriers learners experience, it was suggested to convert the identified factor structure into a diagnostic instrument (dashboard) powered by learner self-report. This dashboard then provides information about barriers learners experience and can be valuable for making (re) design decisions and for developing learner supporting tools and interventions.
