My mother taught in the 70s and 80s. (English)
She was known as an excellent disciplinarian.
She taught tough classes. (for those of who are old enough, she was given a class of ROSLAs in her probationary year - and got them to buy their own copies of a book towards the end of the year. Later, she taught in Clydebank - so not a nice leafy suburb).
She was well liked. :)
She never used the strap (which is what used to be used in Scotland rather than the cane).
She didn't believe in it and didn't need it. Good teachers don't.
Her comment was that most of the kids who "needed"
the strap (as in, some of the other teachers gave them "6 of the best") were already exposed to lots of violence at home and as a result it wasn't effective - and worse, that it taught them that physical violence was appropriate :(.
The proof was that most of them would have prefered the strap to the punishments she gave them (detentions and/or extra work) because it was "over and done with quickly".
