The amount of bad behavior with which she must contend is shocking. It's entirely foreign to me from our childhood, and she has relatively little freedom in how she can handle chronically problematic students.

If it is theoretically possible for the teachers to keep the disruption level low enough for much learning to happen, then the formula is a secret.

It's very depressing, and it has left many teachers bitter, burned out, and I suspect more racist.

Couldn't we draw the conclusion then that wealth plays an important role? Which in turn also affects the pay of the teachers in the area, also affecting the quality of said teachers?

I'm not disagreeing with what you're saying, but what I think is depressing is that it leads to racism, instead of anger over systemic inequality.

Disruption because the class is above or below your level is also, to some extent, uncontrollable by the teacher - they have 30 kids (typically in UK) to cater to.

Teachers can be entertaining, but that isn't always conducive to the subject matter.
