OMG! You definitely need to make a fuss. I'm sorry but that is NO WAY to speak to anyone, child or otherwise, absolutely disgusting IMO. And also considering how much you are paying I would be definitley making a fuss and a big one at that.

One question? Do you think the teacher is respecting your daughter if she's talking to her like that? Yes I believe that you should respect the teaching staff, but don't allow them to behave inapporpriately either. And I'm sure you could ask any teacher on here on BB and they wouldn't be happy with another colleague treating a student like that iykwim? This is your childs education, and if she has a hearing problem and has already said she won't bother asking questions do you think that she's going to enjoy the next year, or benefit from her education? Don't feel bad sweetie, you are definitely doing the right thing and definitely NOT being over protective!
