I am a teacher's assistant in a middle school classroom. Recently, one of the students has taken up quite the attitude with me and even begun to deliberately ignore what I say and cause the other members of the group to even feel uncomfortable with his behavior. I have no idea why he is expressing such defiance, and frankly, I've never seen anything like this before. What should I do?
Adding to this, keep in mind that these students are going through physical and emotional changes. They may not be aware of the attitude they have picked up, so patience is key.
