To be fair, your perspective changes when you're on the other side of the desk. Teacher training in the U.S. is pretty abysmal. The research they're exposed to is largely theoretical or specialized, because that's what your professors have to focus on in a publish or perish world.

Good training would identify the misconceptions teachers are prone to, and the practical application of adolescent psych. There's also an appalling lack of guidance through the states' regulatory framework.
