Of course schools cannot tolerate too much creativity. To go up the down staircase may be a spark of creativity but too much of it leads to problems. The military doesn't accept much creativity, nor do most jobs, Part of the schools job is to teach adherance to rules, not creativity. A martian anthropologist, for example, viewing a street scene in New York City noted that one of our Gods are lights on poles. A certain red signal from a God and people stop walking in one direction, and a green God means the opposite. Perhaps the creativiity is to be found in the homework excuses or in the notes so called parents write to excuse an absence. Besides I don't think creativity can be taught, only allowed.
