Risk is the director of DVD production at the university.
DVD, officially, is a video and computer format. The biggest advantage DVD has over CD-ROM is the broadcast quality video. The ability to interact with the video is what attracts educators most, said Risk. David Nielson, a doctoral student for the Department of Psychology and Instructional Technology at Brigham Young University, said DVD also has applications within the classroom. He explained that textbooks or lesson manuals could have bar codes printed on pages and a simple scan would instantly bring up video clip to explain a concept in more depth.
