A great panel discussion at WISE in Doha addressed MOOCs. If you've been too ashamed to ask (or google) what that means, this is a deep end definition, but a great one. So often definitions over-simplify and trivialise the potential impact of emerging ways of doing learning. This panel looks at what a MOOC is, whether they're a good thing and what the future of MOOCs could look like.
George Siemens jumps in a few minutes into the discussion about whether or not MOOCs are disruptive to the current system and provides a great definition that supports his view that the disruption was inevitable:
"They're part of a shadow learning economy. They're a supply-side solution to a demand-side problem around knowledge that's been building for decades."
