Teacher keeps calling me the wrong name even though I corrected her, think she s trolling me?

You've tried hard to get into this teacher's head, but even with advice from others, you realize that there is no way of knowing exactly what's happening up there. Maybe she's suffering from dementia, as some have suggested. Maybe she has you irrevocably confused with someone else. Maybe she is "absent minded" (a polite way of describing a person who is becoming demented or entering Alzheimer's disease). And maybe she actually knows exactly what she's doing, and is just being "passive/aggressive." But you cannot ever be sure which choice is at play, so you must be the one to take charge. Ask yourself how important it is to fight this battle. Are you soon going to be in someone else's class, or even at another school? Is this teacher for whom you are the "assistant" going to be an important part of your life forever, or is your contact with this person almost at an end? If you're stuck with this teacher for a seriously lengthy time, and the "wrong name" business is really making your work environment unpleasant, then take the matter up with the teacher's supervisor -- the department head, principal, or whoever. That person is more likely than you to know what's really going on and whether "orders from on high" will make any change or not. (Obviously, you do NOT defy this teacher's instructions, confront her, "call her a wrong name," "ignore her," or do any of the other nasty, rude things which have been suggested to you. Those actions cast YOU in the role of the wrongdoer, and you do NOT want to be in that position. If there is any "correcting" to be done, let the administrators do it. So far, you have been polite, respectful, and proper, and that's exactly the position you need to be in. Don't become defiant, insolent, or rude. And if you determine that you'll soon be out of this situation entirely, you might want to consider not taking on this fight at all. I hear you that it is irksome for someone to be calling you the wrong name, particularly when you have made every reasonable effort to make it clear how you wish to be addressed. But someone wise admonished that you should always "Pick your battles," and save your energy for the ones that will really count. You might decide that this is not a fight worth fighting.

Start calling her a wrong name. And maybe she will get the point.

Or maybe she has a type of dimensia.

Nope, you remind her of a Sophia that she has known at some point in her life. It could be either physical looks or mannerism, doesn't matter. So that name stuck. It could be she can't get it unstuck, that is not all that uncommon. It could be it was stuck at first but you made such a big deal out of it that she decided to screw around with it now. A private chuckle. I doubt that if she is as no nonsense as you seem to think.
