Schoolgirl caning in 1970's-1980's in the uk?

I am doing a paper on the deteriorating discipline in British schools and as part of my research I would like information on factual school discipline for girls was there a set ritual was it touch your toes or was you made to bend over a desk or chair did male teachers cane girls were you made to lift your skirt these facts are proving very hard to come by the realms of fantasy on the net bear no resemblance to a real schoolgirl of the 70'and 80's.Please no silly answers
