These extensions allow users to quickly and easily create, find, tag, annotate, and share `clipshows' of their video recorded classes both publicly and privately. Second, the tracking data generated when users create or view the clipshows using these extensions are used to analyze the efficacy of the system.engclipshowmashupvideovideo clipvideo mashupe-learningeducational technologytechnology enhanced learningtellecture capturevideo capturetext
