As I see it, Chapter 6 of Howard Gardner's The Disciplined Mind speaks of the "expert" who continually confronts the "misconceptions" and "inadequate representations" of undisciplined or "unschooled" understanding towards developing "enhanced understanding". This dynamic pushes back at the limits of the traditional, familiar, content-driven curricula. As I see it, Gardner points towards high school as the place to initiate the primary cognitive apprenticeship of adulthood.
Still digesting the "disruptive" nature of the integration of technology into education, there seems to be plenty of opportunity for disruption in these tricky economic times!
