I took some time to break down the Digital Publishing Suite for K-12 educators. If you have additional questions please let me know. We have been doing digital publishing for a while and I think that this will help you get things under way. I have many ideas about how to use this in your course as I have 15-20 Graphics students in a class work on a single publication.

You need to download the digital publishing suite tools. Make sure you get the right tools for your version of InDesign. CS5, CS5.5, and CS6 are avaliable. You need both the folio builder panel and the folio producer panel. They are found on the right side of the page.
