That's how everyone has ever taught at the dozens of public schools at which I've been employed. I really think many people don't have an accurate understanding of public education. Most (certainly not all) of the problems I experience (and this has only been at 4 school districts in 3 cities in 2 counties) come from a shift of responsibility from the home to school. I know that's not true everywhere, but I find myself having to teach students how to speak civilly, dress appropriately, follow generally accepted hygiene practices, sit in a chair, follow directions, cope with anger, act in public.... I used to just teach English.
