I recall two boys being slippered for fighting, by the female games mistress. No doubt the girls enjoyed the sight.
In view of the oft-expressed predilections of some visitors here, I’m tempted to say no doubt the lads enjoyed the slippering, but I won’t!
Our ill-informed visitors who say that mixed PE lessons in secondary schools never happened are for the most part the same people who say that male teachers never administered corporal punishment to female pupils. I’ll be charitable and say that they labor under the delusion that all schools were identical to the one they attended, but sadly the truth is that they just like making stupid statements.
I think there might well be the odd case of school Tawsings other than on the hand, but in general, I think you are correct to assume that, in Scottish schools at least, the hand was the normal target. Tawsing stools, certainly not.
