Even if there wasn't common core though, the way schools keep order and discipline now is through rewarding students with trinkets and points and snacks and things. So, schools try to be "hip" and relate to students as much as possible. Some high schools I go to play hip hop music over the loud speakers as the teenagers walk from one class to another.

It can seem ridiculous, but if I was suddenly in charge of a high school of 3000 teenagers from low income areas, it is what i'd do too because it works. If you do the old school way and just warn, threaten, and punish students, they'd set fires and attack you and each other. In the past, teens at wealthy schools would behave because their parents would kill them if they didn't and teens at poor schools would just go to jail if they were awful.

I do think now that teens in wealthier neighborhoods still behave well in school because their parents would kill them, but in poor neighborhoods what I was writing about above happens. It is weird and like a propaganda community. Like I said though, it mostly works.

The best ones though use the rewards, but also have stern punishments at the same time like Saturday schools and a classroom full of like the 30 or so students that don't follow rules at all. In that classroom, there are like four adults and everything is watched very carefully.

Also, there are a series of different schools where teenagers that get kicked out go to.
