If I have to look at somebody explaining why the Finnish Education system works so much better than the UK's one more time, I may scream.
Here is the skinny; nobody wants the UK system to "work".
Because it is used to control wayward teens without having either the training or the support to do so.
It's the cheapest way to control a problematic part of the population and keep them off the unemployment rolls. The alternative is to allow permanent exclusion, or expulsion, as it used to be called; and then those kids will be causing nuisance to the police and the neighbours, who won't even have the convenience of being able to identify them by their uniform. Unthinkable.
The political convenience is backed up by ideological foolishness of believing that a child who is excluded from school is excluded from society. This may or may not be true - surely everybody of my generation has at least one mate who was repeatedly expelled and has made out just fine - but one case is not necessarily caused or affected by the other.
For example, a seven year old sexually harassing another seven year old of opposite sex and bullying/hitting/fighting many more of his own, who has been PExed twice and is currently permitted to carry on this behaviour because he is a POC and at danger of exclusion sends a clear message, which is that his right to hurt, frighten and bully others outweighs the rights of the other children not to be hurt, frightened or bullied. This is very disruptive to teaching and learning, funnily enough; so his right to act out is also being protected above the right of the other children to learn. The ideology here is acting as a sop to the powerlessness of the staff, however, as actually there is nowhere else for him to go, and if he does, the school has to meet the costs.
So the left and the right meet in perfect harmony, to destroy any working education. Discuss.
