Most embarssing school punishment

I remember ma class 5 ma huda there was one science teacher, just for halla gareko vayera she tried to undress my skirt as punishment and got left with warning and lets not talk about boys, i have seen them being made naked completely in front of whole class for various reasons.I have heard she is still teaching in that school.All these happened just a decade back ani mero neighbouring schools haru ma ni hunthyo re.Does these things still happens or have any of you seen such punishment being given?
