For a behavior issue during class a one to one meeting after class, if need during class have the class do a small project while performing the one to one meeting out of hearing range of the class. During the meeting take notes while the student is expressing their concern then summarizing issue helps define the problem after the problem is defined give the student several courses of action sometimes having the student some up with their own solution resolves the issue. If the student remains obstinate and rejects all solutions then the problem should be escalated to include a third parity.
