Expanding the usability of recorded lectures : a new age in teaching and classroom instruction.
Master's thesis, University of Twente.
Full text available as: AbstractThe status of recorded lectures at Delft University of Technology has been studied in order to
expand its usability in their present and future educational environment. Possibilities for the
production of single file vodcasts have been tested. These videos allow for an increased
accessibility of their recorded lectures through the form of other distribution platforms.
Furthermore the production of subtitles has been studied. This was done with an ASR system
called SHoUT, developed at University of Twente, and machine translation of subtitles into
other languages. SHoUT generated transcripts always require post-processing for subtitling.
Machine translation could produce translated subtitles of sufficient quality.
Navigation of recorded lectures needs to be improved, requiring input of the lecturer.
Collected metadata from lecture chapter titles, slide data (titles, content and notes) as well as
ASR results have been used for the creation of a lecture search engine, which also produces
interactive tables of content and tag clouds for each lecture.
Recorded lectures could further be enhanced with time-based discussion boards, for the
asking and answering of questions. Further improvements have been proposed for allowing
recorded lectures to be re-used in recurring online-based courses.
