This talk will highlight the MediaMixer benefits for the e-learning video platform VideoLectures.NET. The ‘VideoLecturesMashup’ is capable of accepting a specific learning topic as input and produces as a result a mashup of fragments of learning materials from the site addressing that topic, ordered in a meaningful way. The mashup is specifically addressable and hence bookmarkable/saveable for subsequent reference and viewing. The talk will reflect on the new learning opportunities realised for online learners as a result of the MediaMixer technology.
