Where I possibly come into this question of the MRT’s contribution to education is around building ready ways for readers to move between the multimedia representations of teaching and the larger world of education research. The Public Knowledge Project builds systems designed to improve scholarly publishing, and in this process we have developed tools for readily connecting a given research article published in a journal to a host of related materials, including research articles and discussion groups, as well as materials from outside of the academy, including government policies, media reports, instructional materials. So in the case of something like MRTs, it may be worth exploring how these representations of teaching could be connected in a similar way to related materials, rather than presenting each representation on its own, or as an alternative to other ways of representing educational processes or issues. The promise then is for people to be able to move from a MRT that interests them to related materials, to set the teaching represented within a context of closely associated ideas about education from different types of sources. It would be possible, as well, to move from a research study to a  relevant MRT
