Mediathread is an open-source platform, created by the CTL, that supports multimedia analysis within a communal environment. Instructors using Mediathread designate online collections of source materials for a given course and post assignments. Their students are able to collect video, audio, and image assets from across the web (or upload original media they create), annotate them, and embed them into compositions within a course-specific website.
During the 2015-2016 academic year, Columbia instructors used Mediathread in 129 courses. The platform continues to evolve; a new assignment type to facilitate audio analysis in Music Humanities and similar courses among the recently added features. The CTL continues to provide training and technology support for Mediathread, which has been used in over 250 courses since its launch in 2010. Mediathread has been adopted at other institutions, including MIT, Dartmouth, Wellesley, Georgia Tech, and the University of Maine.
