Audrey Watters says:

Theres a line in a 2011 Wired Magazine article about Khan Academy where Bill Gates calls constructionism “bullshit.” It’s a line that’s stuck with me because it makes me so damn angry, no doubt, but also because it highlights Gates’ dismissal of established learning theories, his ego, his ignorance.

And it highlights too, I think, the huge gulf between those like Gates who have a vision of computers as simply efficient content delivery and assessment systems and those like Seymour [Papert] who have a vision of computers as powerful and discovery learning machines. The former does things to children; the latter empowers them to do things — to do things in the world, not just within a pre-defined curriculum.
