being a good kid

So today I was talking to my observation teacher and she was telling me that her and the teacher next door had switched two students. There was one student that the teacher next door couldn't deal with and so she was switched to this classroom that I am in. Consequently, one of the good kids from my class was moved to the other class. After class today, the "good kid" came to our classroom because she was really upset about switching. I totally understand what she was feeling. On the one hand, to move the problem student to a class where she might actually get something done is a good thing but on the other hand, we don't want to punish the other student. No matter what is said to that student she will still feel that she did something wrong. It is hard to be that good student, the one that can adapt to different situations and different teachers because we are the ones that get moved. Teachers look at it as a good thing, that they can move students like this but the student only feels bad about themselves and feels that they did something wrong. I felt really bad for her. I wonder if this change will be permanent.
