I'm currently doing my practicum. I'm in the classroom one day a week and this one child is driving me insane. When I first met her, I thought she's a good girl but reserved and quite. I'm at my half way mark now, I see her true colors. This child is very passive aggressive and won't participate in anything she doesn't want to do. Like for example, if lunch is something she likes (she gets free school lunch), she eats like a pig. If lunch is something she doesn't care for, she slowly eats it. We give them a half hour lunch. Then, nap. There will be times everyone is napping and she's not half way done. During nap, they get to use the bathroom. She always take forever. There's strange noise. So, we think she's playing. Once, I had to take her to another class because someone was in our's. She took a long time and the teacher of that room knocked with no response and pushed the door open a tad. Saw her playing with things in there and told her it was time to go back. We suspect this is all she does. During large movement time, she sits on her spot and refuses to sing or dance. We had a project last week where we had to cut out a pattern and she refused. Sitting there with arms crossed. When asked why, she outright lied and said she didn't know how to use scissors. I've seen her use them before. This is not the first time she's lied in front of me, either. Twice, she's outright taken things from people and when she's been called out about it, she's lied. She's also lied about people taking her things. Many children dislike her and she often starts fights. Now, her quietness is going away a little. She's keeping this behavior and allowing the children to influence her in a bad way. She doesn't pick up on any good habits. This week, the class were sitting in their spots and two children were absent. During the middle of an activity she got up and moved to another spot. I told her to move and she looked at me. I told her "Move, now." She gave me this really disturbing look. Like she was testing me. I told you move now or you go sit by yourself at a table and she slowly moved away. I've known, the mentor teacher informed me, since the second week she is a foster child. She has mental and social issues. She isn't getting anything from the class, and the class isn't getting anything from her. Preschool is not required in my state. Should a child like this be in prek? I think she should be in therapy. I don't know. This is my first real teaching experience and have no one to talk to. Am I a bad teacher?
