Well, the home and school go together. In my son's school (one with lots of hispanic kids) the teacher was told by the hispanic parents to teach the kids in school and skip sending them home with homework, because at home they had other things to do. Of course, doing homework is the single best predictor of success in school, and the more homework the more success. So this parent had it wrong, but as the teacher continued to assign homework, the hispanic kids simply fell farther behind and became more turned off and more distuptive. Not a good plan at all. The teacher btw was a black lady and very consciencious and hard working. She did not have an answer to the challenge to educate in class and let the kids have their free time at home.
Spend any amount of time in a school and it's pretty clear. Poor parenting skills ensure unmotivated kids lacking structure, boundaries, and proper social behavior. It's not rocket science. Respect, authority, and discipline have been taken out of the schools by parents and govt. How can learning even begin to take place? They just continue to talk about academics and blame those evil commie teachers.
