There is an shocking lack of respect in schools these days on all sides - pupils to teachers, teachers to pupils and parents to the school.
When I was at school, there were no rules about not going to the loo in lesson times and there wasn't a issue with 30 kids trying to go, so this idea that if schools relaxed the rules, suddenly every child would want to leave class is ridiculous.
If we needed to go we asked, sometimes the teacher would ask us to wait five minutes or just finish something but I don't remember anyone every being stopped.
Kids in school have a lack of respect for teachers because they are not respected themselves - respectful behaviour is not modelled to them, so they are not learning it.
Instead of respect, so many schools rely more and more on draconian rules, whereas school that fosters respect and inclusion, don't need as many rules.
My DDs school has the "No taking your blazer off without permission" rule - not all teachers think it is a sensible rule - one in particular that I know of tells the students in his class that they can take their blazers off, or go to the classroom sink and fill their water bottle as long as they do it quickly and quietly and don't disrupt the lesson.
He finds it incredibly frustrating that half of them still put their hands up to ask as that disrupts the lesson more than them just taking the blazer off! He treats the kids like people, no seating plans, will chat to them, joke with them etc, but makes it clear he expects the work to be done. I know this because he has told me first hand. He is an amazing teacher and always asks after my eldest, even though she left the school two years ago (having achieved her best GCSE grade in his subject even though it was her worst subject at the start of year 10)
Other teachers spend half their time trying, and failing to control the class, enforce every draconian rule going, treat the students like little automatons, have a seating plan which they change all the time in a desperate attempt to try and improve behaviour, without really understanding why kids misbehave for them while behaving perfectly for others.
There was one teacher the other day supervising phone pick up at the end of the day - literally the last five minutes, kids queuing in 25 degree heat, spending her whole time screaming at them to put on their blazers or they wouldn't be allowed their phones - she is universally disliked amongst the pupils.
Guess which teacher has the lowest number of bad behaviour incidents recorded in his class and who also gets the some of the best test and exam results in the school?
School is a place for learning - they need to start teaching children respect by modelling it, not trying to compel it. There will always be young people who misbehave, who push the boundaries and who will seek ways to get into trouble - they will do that no matter how draconian the rules.
However, most young people just want to get on with learning - we need to stop treating them like every single one of them wants to go to the loo in lesson so that they can smash up the sinks, smoke a vape and bully a year 7 - the vast vast majority of them don't want to do that - they just need the loo.
Perhaps if schools stopped trying to police everyone for potential bad behaviour, they would be able to focus on actual bad behaviour.
