Could not Post Catagory this is not a MYSTERY MOVIE!

I think I saw this movie on TCM Turner Classic Movie Chanell. It was in color I am almost positive, there are a lot of movies rolling around in my head. It was possibly early 1980’s or lower. I think it was a foreign film but in english, if not it was subtitled.

It had a woman teacher who had some students (Boy) students who were masturbating in the back of the classroom, she brought it to the attention of the principal or headmaster, he told her to teach  them to respect her she should handle the punishment herself, or something to that effect. I don’t remember other parts thats what sticks out the most.
