Class size and Education

It looks like it doesn't help as much as we're told. But, the things that do "frequent teacher feedback, the use of data to guide instruction, high-dosage tutoring, increased instructional time, and high expectations" would make teaching more difficult. And we wouldn't be spending all the time on non-teaching stuff. Ah well.

UPDATE: A nice hour long podcast on teaching matter. I think I have already linked to this.
