We would ideally also have the option to limit searches to one textbook at a time.
Yes.
About interchangeable modules (that is, using one module for multiple textbooks): this solution may be inideal because the goals of each textbook are different
Are the goals different? Or rather the background of the readers and the level of the course?
If I want to learn something about DNA, I just want a part that is suitable to me. The other 300 pages of the book might not interest me.
and editing a module for one book will sometimes make it less suited to other books.
"Books" are a very paper-based concept, just like chapters and pages. In E-learing one talks about "learning units" or "learning objects". Creating a course is then selecting units from a respository.
Just take a look at the Connexions Project. Their courses are made from distinct modules.
Books make a learning experience very linear. By modules you can create different paths, according to the wishes of the targeted audience and the level of learning they want.
Some learners want some very advanced modules if topic X, but just touch slightly upon topic Y. And others vice versa.
Even if I were to take my own organic chemistry book and rearrange it I would have to rewrite many parts of it to make sure that supporting ideas arent being thown out there before they have been properly covered.
If something is not covered why not just provide a link to a relevant modules that does cover it? Mozilla has a nice browser-addon called Dynamic Links: by just control-clicking a word (yes, any word in a html-document), you can sent that word the any search-engine you want, like Google of Wikipedia. With this, you don't even have to provide a link. http://dynamiclinks.mozdev.org/
The advantage to reusing modules is that it saves a little bit of copying and pasting, right ?
