On a visit to the Home Ideas Centre in Sydney I found they have a very good architecture and design bookstore. I asked about books for designing electronic classrooms. Jon Ruwalt, the bookstore manager, was not put off by the unusual request and suggested The Oregon Experiment by Christopher Alexander.
This was the project which lead to Alexander's theory of Pattern Languages, now used for software design as well as architecture. It would be appropriate if this could be used to design both the classroom and the systems for it. However, that is a long way from practical designs. But perhaps someone has done some patters which are applicable.
