| Popis: | MOOCs promised to herald a new age of open education.However, efficient access to MOOC content is still hard, thus unneces-sarily complicating many use cases like efficient re-use of material, ortailored access for life-long learning scenarios. One of the reasons for thislack of accessibility is the shortage of meaningful semantic meta-data de-scribing MOOC content and the resulting learning experience. In this pa-per, we explore Concept Focus, a new type of meta-data for describing aperceptual facet of modern video-based MOOCs, capturing how focuseda learning resource is topic-wise, which is often an indicator of clarityand understandability. We provide the theoretical foundations of Con-cept Focus and outline a methodical workflow of how to automaticallycompute it for MOOC lectures. Furthermore, we show that the learners’consumption behavior is correlated with a MOOC lecture’s Concept Focus, thus underlining that this type of meta-data is indeed relevant for user-centric querying, personalizing or even designing the MOOC experience. For showing this, we performed an extensive study with real-lifeMOOCs and 12,849 learners over the duration of three months. |
