Well, it's not too long ago that violent abuse was part of the education system.
All teachers at my secondary school were issued with "The Tawse" as an "enforcer" and some took great pleasure in administering large doses.

400mm long x 40mm wide x 10mm thick.....not pleasant, but it worked up to a point!

The great Matt Mcginn, himself a teacher had the following take on wean control :0)

Chorus:
Rap tap tap upon yer finger
Rap tap tap upon yer palm
rap tap tap upon yer hand
And I'll leave you with a blister like a Belfast ham

1 Before I ever took to teaching I was a fairly decent chap
Then they gave me fifty weans and a lovely length o' leather strap

2 'Och!' says I 'I'll never use it, weans can respond to talk'
I told them that then turned aroond and a boy let fly a cake of chalk

3 'The boy that threw the chalk' says I 'He'll never grow tae be a man
He's far too feart tae show himself' But he did and threw another one

4 To strap a boy's an awfy business, every one's a mother's son
Take the strap frae a' the teachers - issue every one a gun
