It might be helpful to involve a counselor, to see if they can get the student to open up as to why they might be acting out. I'd also suggest meeting one-on-one with the student and creating a behavior contract with them.

This could be a serious warning sign that the student might have some kind of mental condition or could develop one in the future. He could be depressed and start to feel like the world is against him. I would kindly tell the student that I am on his side and I am his friend no matter what. I would definitely have a conference with his parents to try and understand what the student is going through in his home life. I'd want the parents to be aware of the issue and make sure they do not write it off. I would not want the problem to escalate.

I think this is a good time to use the applied behavior analysis approach. In order to find out why a student is exhibiting a certain behavior, someone should observe the student and find out what happens before and after problem behaviors. The teacher could also have a one-on-one chat with the student to find out what might be going on.

I would talk with the student and figure out why they hate school maybe by have them write in a journal to the teacher first. Maybe it's just an issue with low self esteem and with help from a counselor and the journal could help them get along with others better.

Suggest to the student that he or she should write down suggestions to make the specific situation better. What is it that you hate about school? Write down a solution. Many will be improbable solutions but you may get one or two that can be implemented. This would also help get to the bottom of what is truly bothering the student.
