You ever see the movie Independence Day? You know, the first one with Will Smith and Bill Pullman? Remember how they couldn't even scratch that alien ship hovering over Houston with a nuke because they couldn't get past the aliens' defense shields? What was the answer? They had to destroy the mother ship in order to take out the other ships.
Those who know me, know that I am very much not an incrementalist. I own that, in any discourse I have. However, if we are ever going to initiate any real and transformational change in education, then the system has to be fundamentally changed top to bottom. If we just continue to nibble around the outside, or concentrate on the "smaller ships", there's always going to be something that will come around to obliterate the movement.
