I don't buy the assumption that the biggest problem is teacher quality. It's half and half. My wife has a 2nd and 4th block, same material, same environment, except the latter has such a poor group dynamic that they significantly underperform the other class. Variables here are time, teacher fatigue, blood sugar, and the students. I feel that the last factor has the greatest effect. And I totally agree with the fact that there's an abdication of responsibility from the parent/guardian(s) in that they feel the intrinsic motivation for the student ought to be provided by the state. But then we have teachers who have tenure that play videos all day. Good times.
