This morning's TED talk was Richard Baraniuk's 2006 Goodbye, textbooks; hello, open-source learning lecture. He wants to take a large number of books, break them down into small chunks, package each chunk in XML to make it easy to combine with other chunks (not necessarily the ones it originally came near) and replace the idea of a textbook with the idea of a collection of such chunks. Okay by me.
Actually, I'd like to see chunks, video or audio or text or all of the above, labeled with pre-requisites and objectives; these labels would also appear on knowledge maps like the Khan Academy's. Then you place yourself (or your teacher/tutor/advisor places you) on the knowledge map, perhaps by taking quizzes, and you identify your final objectives, and we identify lessons which are claimed to get you in the right direction....
Or then again, maybe not. The Connexions website did seem both clunky and underpowered, but maybe that's just me.
