Math:
"Where is the data to support the assertion about alleged constant distraction caused by makeup?" Where is your data or experience of the classroom that says it doesn't? Genuinely it can be as big a distraction as the mobile phone.
To the argument on the perception of schools? "As long as uniform exists, it will pander to the worst prejudices of British society." Oh please, people making judgements about the quality of a school because of uniform isn't about it being selective or public school and about wealth issues, its more about the structure and nature of the school, I think people take an impression that if a school has a good uniform it must be a structured and constructive learning environment, no judgement on the wealth/class of parent.
As such the presentation bit is only a small part of the argument for uniform but one that I made previously. Many others have stated reasons why they like it, and there have even been posts from those whose children are in non-uniform schools who said that they would prefer it. You may lol at overwhelming majority but when I did a count ( and I'm certainly not counting again) it was 27 against and 56 for (some with but less strict) which is an overwhelming majority, there have been plenty since that count who have said that they back it too (mostly who post once) and nowhere near enough posters who are against to catch it up.
Your comments about tribalism? Well in the U.S and other places where there is no uniform tribalism comes about through what you wear in high school anyway I've always thought the "waterhole" scene of Mean Girls illustrated my experiences in the American High School system well (albeit in an amplified version for film).
"Schools are factories where teachers must produce results, and therefore students must not be distracted by anything because the teachers' reputation is at stake. So uniforms are there ultimately for the sake of the teachers."
Uniforms and the appearance of the students pander to the ignorance and prejudices of the public, whose perception of a school leads to higher enrollment, which in turn leads to funding, with the opposite holding true too, and all of this is fine. "
My arguments for uniform are generally that:
It is a greater leveller in terms of appearance, broadly. In can't do it in an absolute way but in U.K schools it does help. This is felt by many of the public.
Parents in the majority back it for reasons of practicallity etc etc.
It can help structure a good learning environment where appearance isn't the ultimate expression of individuality and students are free to stop thinking about what they look like, and can therefore concentrate on the work.
In some ways it prepares students for the world of work, having to fit into a dress code etc etc. It can also help give them a "work" mentality in shool and a seperate sort of behaviour and attitude from home.
The public perception of schools is effected by it, because uniform is part of British culture the presentation of students can help shape a public perception of a good school. This can effect the number of people who are willing to send their children to the school.
It can help foster students pride in their own school/community.
Your points about kids driving, getting jobs going of to Uni? Well it seems kids have been doing that having worn a uniform in the U.K for decades quite successfully (but its harder to drive over here, you know on roads built for horses and carts not cars and we don't do automatics so actually more challenging lol) So you can't really say that we don't do that successfully because of uniform, also most 6th forms relax the rules anyway.
The exam factory element is there yes, but that again is down to stakeholders, parents, school management, OFSTED, the DofE all place huge pressure on teachers to get results from students, and allowing a student to fail because of their own attitude (or ineptitude) is seen as a failure for the teacher.
So there, I've said before that if we were to go non-uniform I'd be fine with that too. But there are lots of arguments for it, and many more parents support it than are against it.
