I believe behaviour of children in Britain has deteriorated since caning here was banned. The way I remember it being used was only for serious misdemeanours (never bad work) - particularly disrespect to teachers. The caning would only be carried out if the pupil agreed to bend over, never just lashing out - 2 to 6 strokes on a boy or 1 to 3 on a girl, though for them the thought of the cane was usually sufficient to deter them. I think the chief problem is when teachers do not use it in a controlled way. Then the punishment is resented not accepted. One solution tried here before a complete ban is for the pupil to have a choice between cane or detention. This makes the teacher calm down first.
