If ever there was a title that took me straight back to my time at school, this is it. It's not that I was unruly, naughty or deliberately disruptive. Somehow I just always seemed to be the one asking "why?" and "How?" and often being told "That's all you need to know for the test".
Christensen et al are not writing about those pupils who make life difficult for teacher, though, at least not directly and not with the word disruptive. They're talking about the application of Christensen's theories of disruptive innovation to the American education sector, with a focus mostly on K-12.
