Donald Clark doesn't hold anything back in his criticism of the leaders of the open education movement, and in many respects, it's hard to disagree with him. "Empirically, we’ve seen in Wikipedia, YouTube, Khan, Duolingo and MOOCs, truly wonderful examples of how pragmatic and sustainable openness can be achieved. Yet these are the open resources that get the most mud slung at them. Rather than sniping, educationalists should embrace the decentralisation, democritisation and disintermediation of learning through such resources." They can't, though, because of "an obsession with reusable learning objects (this led to the largely hopeless SCORM standards) and a far too ‘teacher-oriented’ view of reusability."
