Reviewing Christensen’s Disruptive Technologies (Harvard Business Review, 1995) in MOOC Terms

One of the common citations in xMOOC artifacts and discussion is the idea of xMOOC as a disruptive technology.  The concept, developed by Harvard Business professor Clayton Christensen, is tossed into discussion as if it’s vital reading I should already know…none of the authors do more than give a cursory definition to the concept in abstract fashion rather than concrete, and in all of the articles I have read, I don’t see consensus on the definition.  This makes me think several possibilities:  1) this is a concept so integral to this field that I should know all about it and am an idiot for not having a foundational knowledge, or 2) this is a concept not fully understood but thrown out there in a way that sounds erudite but lacks foundation.  I think it’s a mix of both.  As a learner struggling to grasp a topic (my background is in both media and social sciences, not business), the best way is to personally dive in rather than rely on the previews of others.  At the same time, it took those previews to get here, so perhaps this review can help others start to nail out a more complete definition on the topic.
