Instinctively and intuitively, I am skeptical about MOOCs. Many are similarly inclined and are outright dismissive in their reaction to them.
However, experience suggests it is precisely when we are most set in our opposition and predisposition that we need to step back, consider things more deeply, reflect and ponder if our presumptions are acting to preclude us from learning something that is just new, different and/or an alternate perspective.
It is in this vein that I recently discovered the ideas of Stephen Downes, well presented on his blog and illustrated with this presentation.
