The teacher shouts at them, to make them 'tough' and they have to stand motionless in line waiting for further instructions. Similarly, music is interpreted as learning to read notes. This has little to do with music, in fact it often destroys feeling for rhythm and frequencies. There is no room for creativity in such activities. Every little movement is preprogrammed and has to be done exactly as prescribed.
Any individuality is beaten out of the kids.
They are taught that the highest honor is to become the best robot in the line and to receive a prize for that in one of those disgusting ceremonies. Amazingly, the classroom syndrome also prevails among homeschoolers. Many families prepare activities for their children in great detail and then come together at the home of one of the families to instruct the children what to do. What happens then is shocking. The children are being taught maths, reading and writing, as if they were at school.
