Have taught in an extremely poor district, and now teach in a fluffy, rich district. Unfortunately, due to cultural decay and NCLB, our educational system is fundamentally flawed, I'm afraid. I'm just a squirrel trying to get a nut.
Slouching is easier. I passed more than 90% of my students no matter what happened. It's just good policy, less hassles, and hey, nothing wrong with slouching. Advice to all teachers: pass more than 90%.
One of the crazy things a student told me after I asked him what he was writing in my class. He never turned in homework, and I NEVER saw him write anything else--I didn't know he could write otherwise.
