... takes on the union drones at EDWise on the subject of class size.
Update: Well, that stayed somewhat civil and the teachers made some good points (of course, they were points I had already conceded). No one had a response for my assertion that the current research failed to show any advantage in decreasing class sizes across the board. That's because there is no valid response. If there were any valid evidence, and the UFT surely has access to classroom data, they would have ran it up the flagpole long ago.
So, I'll stick with my present opinion: first you fix the broken instructional delivery system, then you worry about tweaking the class sizes to make sure the implementation can handle the class size, targeting areas that need reductions the most, like the early elementary years in low-SES schools.
