Nice idea about a book like module that has collaborative document properties. Maybe in some way integrated into book.
I would welcome your feedback on some ideas we have been working on. Context IB Science teaching in an International school students between 11 and 19.
I have started using the book module as a major tool in course design. This was given extra facility since I discovered the ePUB import and export tool that has been developed by Ordbrand at lucidor.org. This put together with CK-12 Flex books and other materials http://www.ck12.org/teacher/ which can be imported in ePUB format into Book. I having been grappling with how to open this all up to teachers and students to collaboratively analyse select and adapt/edit and enrich with quizes videos podcasts this vast amount of content .
The results exportable as e.g pdf ePUB both now available and odt as wish would allow teachers and students to add to the growing commons of learning materials.
