My DD 13 who is in year 9, came home today and told me that one of her teachers called her a freak (twice) and a muppet during a quite informal exchange during class. She says he was joking and although she doesn't seem very upset about it, she thinks it was mean of him to say that. It's her favourite subject and a teacher she really likes.
I think that it's unacceptable for a teacher to speak to a pupil like that and I want to make sure it doesn't happen again, but I'm not sure how to go about it. Should I approach the teacher in question, or the head of year? Email, phone, or face to face?
Am I overreacting? What would you do? I'd really appreciate other people's opinion :)
