I'm trying to get our school to have something approaching a coherent mobile policy.
The only limit at the moment is no use in class without teacher permission. We are a school of zombies at break and lunchtime and it's just not healthy.
I have managed to get them banned from the canteen - partly as it was leading to rudeness to staff. I presented the evidence to the head who said he would arrange for the issue to be discussed.
It was. On my day off. And my views and intentions were completely misrepresented and they have decided to do.....nothing.
Anyway, long story short, what are your schools' policies on mobile phones.
