School is outdated, it was designed in the industrial age in order to prepare people to work in factories, we do not longer work in factories (most of us) so school is in need of a huge reform. That's why children are sitting in lines, just like in factories, and the teacher plays the role of the supervisor in factory. Even the bells are similar. That's why kids hardly learn anything in school, because learning is a much more interactive process than the one in schools.
Additional fact:
Scientists say that is difficult for the brain to learn anything before 10 AM, so schools is anti-scientific anyway.
