Improving the OER Experience: Enabling Rich Media Notebooks of OER Video and Audio

Brandon Muramatsu, MIT Andrew McKinney, MIT Peter Wilkins, MIT

Conference Theme: Open educational content

Abstract: Need to find a specific segment in an hour-long OER web video, webcast or podcast of a lecture? Want to read a transcript of that lecture? Want to bookmark, annotate, or discuss video or audio clips from an entire lecture? The SpokenMedia project at MIT is developing a web-based service to enable automatic lecture transcription. And it is developing a suite of tools and services to improve interaction with OER webcasts and podcasts enabling students and faculty to create rich media notebooks to support their learning and teaching. The open educational resources movement is currently characterized by a vast amount of textual content (in PDFs, web pages, wikis, etc.) and a growing collection of video and audio lectures. Learners and teachers can easily locate materials in the large text-based collections such as Wikipedia or OpenCourseWares, and in most OERs. However, it’s much more challenging to find the equivalent specific video segment out of an hour-long OER video lecture. Video and audio is currently searchable based on the textual metadata cataloged with the resource. This data is usually limited to a title and description, and perhaps a few tags or subjects. Better crafting of the titles and descriptions of these videos can only go so far to improve discoverability—why not use the lecture content itself to find the exact clip a student needs to improve his/her understanding? Are there tools and technologies that the OER community can use to improve the discoverability of video, and more specifically to find individual video segments to provide a richer learning experience? The SpokenMedia project at MIT is developing a web-based service to enable automatic lecture transcription. The project is also developing a suite of tools and services to improve interaction with webcasts and podcasts enabling students and faculty to create rich media notebooks to support their learning and teaching.
