Yes, schools encouraging children to compete with each other, about everything from academic success to how many dojo points they get (by class votes, leader boards on the wall, certificates in assembly), then acting baffled when the children start putting each other down. I've had a teacher (who put leader boards on the wall about everything) tell me 'this class is so competitive (amused laugh)'. I thought, 'of course they bloody are. You've encouraged them to be.'
I realise teachers sometimes do this because of pressure they're under themselves, to get good results, and sometimes it's decided by management, but sometimes they do it when there's absolutely no justification (competition between 9 year olds for dojo points???).
And the stuff about 'if you miss X number of days of school, your grades with go down from A to B', don't people understand the difference between correlation and causation? Of course children who miss school (because of physical/mental health problems, bullying, chaotic home lives) do worse in their exams - but because of the health problems/bullying/home problems, not because of the missing school per se. Those statistics are based on between-children comparisons, because it's not possible to compare the same child's performance with good attendance, and with poor attendance. It's so disingenuous to claim it's the missed lessons alone that caused the lower grades, and just makes children who already have problems feel worse about themselves.
