Teacher union doesn't want any kind of performance based system - they're the villain.

Even if there is variability of pay, at least society would be far richer, so being poor wouldn't suck so bad.

But you just told me we don't want to punish teachers for low test scores and the solution is flipped classrooms.

Prove that teacher quality and not curriculum design or cultural factors is actually what's holding down education in poor districts. (You do realize that teachers don't get to choose what they teach, right? Curriculum is set centrally.)

I said don't don't punish teachers, simply fire all of them. Let charter schools compete to lure students.

Personally, I'd want to see self-directed curriculums with a core of entrepreneurship and computing.
