This can be tough. I suggest starting a behavior chart for the student. This will be between you, the teacher and the student. First, find an incentive. Something you know he will work for. He can only get the incentive if he keeps comments to himself. Each class period, he will start over. He gets a strike each time he makes an inappropriate comment. Three strikes and he loses his incentive.As the behavior decreases, instead of starting over everyday, start over every week. This will give you time to work on the bigger issue. Maybe it's attention- seeking or maybe he is struggling in the subject are. Hope this helps. Good luck!

Establish a sequence of consequences for each instance. For example, a three strikes policy. The student gets two warnings, one for each outburst, and is then given a referral if the behavior continues, removing them from the classroom if needed. This should only occur after you sit down with the student and explain that their behaviors are not appropriate and are disruptive, in order to gain insight on why they might be doing this.

Let the student know that is inappropriate and rude to blurt out in the middle of class. Find out if he has any issues or a disorder, if not let your administrators know about this situation if it continues.

Talk with the teacher about their classroom rules and management policy. Is this happening during instruction or during independent practice? Many students take time during IP to chit-chat, and sometimes teachers think that its okay. But if some students are taking that time to talk about inappropriate topics, talking should probably stop. Even as an intern, you have authority to speak with the administration if a student is making you uncomfortable. I would use it.

you could try a system where you get him to stop look at a checklist and if it isn't on the checklist then the student will not be allowed to mention it.

I would take this to administration if this continues after speaking with him. Also, you should maybe teach a lesson on appropriate conversations in class.

Having a conversation with the student. Asking guidance to get involved, and maybe the behavior specialist. Also, asking the parents how they deal with the behavior at home, or if they even see this behavior.

tell the student that is inappropriate and rude to blurt out in the middle of class. Try to find out if he has any issues or maybe a disability, if not let your administrators know about this situation if it continues.

I would suggest creating an intervention for his inappropriate behavior.

Create a discipline chart. Give the student strikes. First strike, a talk in the hallway. Second strike, a call home or parent conference. Third strike, detention or some type of behavioral discipline your school provides. Fourth strike, sent to the office with a referral. But if the student does well, praise the student. Everyone needs a "Good Job" or "You did wonderful in class today".

talk to him and explain his behavior
