5. Video
5.1. More Power, More Complexity
Although there have been massive changes in video technology over the last 25 years, resulting in dramatic reductions in the costs of both creating and distributing video, the unique educational characteristics are largely unaffected. (More recent computer-generated media such as simulations, will be analyzed under ‘Computing’).
Video is a much richer medium then either text or audio, as in addition to its ability to offer text and sound, it can also offer dynamic or moving pictures. Thus while it can offer all the affordances of audio, and some of the text, it also has unique pedagogical characteristics of its own. Once again, there has been considerable research on the use of video in education, and again I will be drawing on research from the Open University (Bates, 1984; 2005; Koumi, 2006) as well as from Mayer (2009).
