Have a good friend who is a public high school math teacher in the NOVA area of DC.
She said she would be "overjoyed" if ANY student in ANY of her classes would raise a hand with an answer or to ask a question, and that half the class is routinely asleep.
One of her 15 year old female students was being pimped out by her MOTHER, with the tricks going down in the girl's/mom's house.
She has now taught on Long Island, Syracuse area, and DC....says it's "the same everywhere."
She really paints a grim picture of the schooling scene in 21st century America, believe me.
