Abstract:

Massive Open Online Courses have gained more and more popularity in the recent years.
Video Content contributes a vital aspect of the learning experience in MOOCs.
The paper at hand proposes ways to optimize the video experience in MOOCs.
Single stream videos will be considered as well as the openHPI's dual stream video player.
openHPI is the MOOC platform of the Hasso Plattner Institute, providing MOOCs to thousands of users since 2012.
One of the unique features of our video player is the possibility to play two synchronized video streams.
Based on collected usage data of our html5 based video player we evaluate the learners acceptance of features, such as adaptive playback speed, dual video scaling, fullscreen mode, slide navigation and subtitles.
Furthermore, we will discuss the impact on the users learning outcome.

Moreover, concepts of usage of MOOC video content (including dual stream video) in no- (offline) or low bandwith szenarious including the usage of mobile devices will be discussed.

Finally UberCaptions is presented, a prototypical tool to enable user contributed transcription and translation of videos in MOOCs.
