What satirical points are being made about education through Scout's experiences in school?

There is certainly a cynical bent to Scout's experience at school. Scout has more educational freedom and positive reinforcement at home with Atticus than she gets with Miss. Caroline. Scout is scolded for reading too well. The teacher completely misreads the rural farm culture that her students come from. Her stories about talking animals are humorous to her students; they are much too used to the practical realities of animals and farm life.
