She's complained to me a number of times that their science teacher frequently comments on several of the girls' personal appearance. Apparantly he tends to 'pick on' specific girls, particularly the - for want of a better word - pretty/popular ones (ie not the geeky ones!) if they aren't trying hard in class.
DD is very clear that he's never singled her out, (unsurprisingly since she's ms science geek) - but she says that she knows some of the girls he does pick out are already funny about their weight, and she feels it's unhelpful if a teacher calls them 'fat and stupid', even in jest.
So far I've suggested that she sits quiet and says nothing, since she has many more years of being in his class - but would you be more sympathetic - and if so, any helpful suggestions??? (I'm sure he's trying to be lighthearted and funny, and just jolly them along, but it does sound like not the best approach with teen girls.)
