I have just started a new job and have 2 TAs in my room who are very opposed to any different. The just harp on about how the last teacher did things and are passive aggressive about my teaching rolling their eyes and folding their arms. My biggest issue is the side talking when I'm teaching. The children are really little and I have a limited time for instruction before I lose them. And yet for those precious times the TAs talk very loudly about absolutely inane crap. I have tried stopping and waiting but to no avail. I don't want to be rude despite their rudeness in talking over me, but I do need to make them aware that this is really unhelpful. I've worked with loads of TAs in the past but this is the first time I've experienced such a disrespectful environment. Any suggestions?
