Not surprised at all. I work in schools doing IT but I don't teach... I have a degree, I have a good teaching manner, I am able to think, I've had offers from private tuition companies to teach, I've run youth clubs and karate clubs with a hundred screaming, adrenaline-hyped kids. Never had a problem with the kids. Wouldn't touch a teacher's job with a barge pole, though.
Kids cannot be disciplined in schools with the modern legal environment. It just doesn't happen. You can shout (if the school lets you, as pointed out above), you can report to the head (who will ignore you until it's time to expel, sorry, "exclude" the kid), you can (possibly, after lots and lots and lots of paperwork and visits and parent co-operation and months of time) get them suspended or "excluded". That's it. And then the law says that the local authority has to find somewhere for them, so they get put into another school (who don't really get much choice but to take them) and the whole thing starts all other again.
Detention is a farce for any kid that gets them regularly - they just don't turn up or try to start a fight with the teachers. Schools sometimes have special areas set aside for the problem kids - I've seen one with a Playstation for the kids' use and where mobile phone use is allowed, so they phone up the kids in OTHER schools special units and have a chat with them while playing games - guess what they do next time they want to phone a friend? They play Who Wants To Be A Millionaire, on Playstation in the "naughty room" after decking one of their classmates, that's what.
You have absolutely nothing that can make them stay in class. Nothing. You are stuck in a room that you can't leave with an open door. There are 30 kids, about 5 of whom want to learn, and you can't really stop any of them leaving, can't discipline them, can't rely on any form of punishment at all. You have a stern voice. Now, in the right vocal cords, that can do wonders but that's **IT**. You don't have anything else without risking your job.
In my last school (a slightly-below-average English secondary in not a bad area), every lesson, every corridor was monitored on CCTV. We had to submit more incidents to the police which involved teachers disciplining kids than we did kids actually doing stuff (mainly because every kid's parents would bring legal action for stopping a kid leaving a classroom, but nobody cared about the kids smashing up the place or walking around out of lesson so long as they weren't causing a problem for the specialist behavioural teachers on duty).
In a classroom, it takes twenty minutes to sit them down, another twenty minutes of discipline and confiscation of gadgets and twenty minutes of actual teaching to make a GOOD lesson. And most lessons are far, far below that, unless the Ofsted inspectors are nearby (please, please, institute random, warning-less inspections, for God's sake!). And, despite modern thinking, you can't "incentivise" because the lessons can never be controlled enough to get the kids interested in the first place.
Even now, sitting in a primary school, I have had to very carefully break up fights where the consequences for the kids are pretty much a stern word, maybe a letter home that gets ignored. And this is a BLOODY GOOD school. My previous school was a struggling secondary school in "special measures" (i.e. it was crap).
In the secondary school, we had happy slapping incidents where the mobile phone footage from confiscated phones actually showed teachers not even notice kids get the crap kicked out of them IN CLASS and then run from the room, being pursued by half a dozen other kids - the noise and movement in the room was that bad. We had teacher's whose "lessons" were often "sit on the computer and doodle in WordArt, while talking to each other and playing on your phones". Not just at certain times of the year but ALL YEAR. Because it was easier than trying to discipline them. We had kids storm out (well, cause disruption and yell for 30 mins before leaving) of GCSE exams because they were going to be a mechanic "like their dad".
From an IT perspective, IT rooms were trashed and we could narrow the culprits down to the millisecond on CCTV but nothing ever happened unless someone stole an entire base unit or similar. Kids wandered into the IT office (or, indeed, any door left unlocked by a lazy member of staff for a millisecond) and "just looked" at the laptops in the corner of the room when they thought you weren't there. Parent's evening you would lose a handful of laptops, a couple of base units or a few flatscreens (even in one primary school I worked in - two laptops stolen in a single parent's evening).
The bad kids (and there is still a distinction and a small minority of good kids) have NOTHING to make them stay in school. Nothing. There's no incentive, no consequence and the only thing that results from playing up is things that just add to their street cred or they get to play Playstation. And yet the schools are forced to keep even the worst of them in school for months and months and months until they can get rid of them.
The teachers are welcome to it. A lot of them bring it upon themselves by not complaining to those higher up but there's no way I'd go into teaching until it was sorted. And I'm one of those Maths and IT graduates that the government are crying out for at the moment. I can get a decent year's wage just by agreeing to train as a teacher (a 1 year PGCE at university) and it wouldn't be enough if it were ten times as much.
Funnily, though, when you put the same bunch of kids into a karate club where you can make them do 100 push-up's, use them as your demo student for pressure points, throws, holding the pads etc., can ban them (and physically eject them) from the club in a second because you want to, don't take any rubbish from them, shout to your heart's content, don't take ANY backchat of any kind and send kids home immediately if you find that they've even been fighting with other people in school, or swore, or called someone a name, you don't get problems.
Weird that. That discipline stuff must work.
