Randomly stop 100 6th graders and ask if they know the definition of supplementary and complementary angles.

I’llĀ  bet Sal Kahn and Bill Gates don’t even know, and probably don’t care.

When is the last time you used or needed to know absolute value?

I will bet that many of those 6th Graders could work an iPad, discuss cosmetic dentistry, or talk aboutĀ desalination plants.

Who (and how) is deciding what’s important and what’s relevant, and then how to measure it.
