An educator does not deal with driven, curious, and happily intelligent people all day. Her job is instead to take the lazy, complacent, and dull-minded and instill knowledge and analytical ability.
"Hundreds of people are spending 20 or 30 hours a week just taking free Massive Open Online Courses, or MOOCs. They're not looking for credit, just the challenge of learning."
Hundreds, huh? Out of MILLIONS? They are the outliers within the outliers!
MOOC addicts are not the norm.
iPad owners with 4G connections are not the norm.
Slashdotters are not the norm.
AP students are not the norm.
Increasing access to those who already have access will give only marginal gains. If you want to start a revolution in education, focus on the students that regularly receive Cs, Ds, and Fs as course grades. Change THEM and you change the world.
