Does the teacher know that this meeting is happening? If so, maybe you can ask to observe the class first for a day, so you are better informed about what's going on.
I don't know if she does know about this meeting. I have been invited to attend and share my concerns but it makes me very uncomfortable and I don't think I will attend.
ETA: I think the reason the teacher cut off volunteers because parents have been complaining to her about how she is running the class. For instance, for reading groups she has the kids reading The Boxcar Children series and Cam Jansen instead of books with more substance to them like Junior Great Books.
