Hi James
I think you make a good point here, and one I’ve heard of as the ‘holy grail’ of MOOC development, and certainly a more sustainable way of looking at things from a time and cost point of view.
I’m not sure if the possibilities vary by discipline – my view is that in my discipline (business) our audiences for different courses are so diverse that not just the content but tone and feel need to be radically different – e.g. an MBA student with existing business experience has very different needs from an undergraduate who has come to university straight from post-16 education, even if they are studying the same basic syllabus. Therefore, if I was designing for a particular cohort, the MOOC audience, if different, would find their needs poorly met, in my view, by the course I’d developed for the other, without significant tailoring bordering on a rewrite. Perhaps I’m just being grumpy!
