When a student misbehaves during instruction, ignore the misbehavior whenever possible. If the misbehavior is disruptive or poses a threat to the child or other students, then you must step in. However, you can often ignore minor incidents that do not put the student or his classmates in danger. Students who misbehave to get attention will learn that their behavior does not produce the desired effect and will stop. In addition, halting instruction to deal with misbehavior is often more of a disruption than the bad behavior itself.
When misbehavior occurs during a lesson, use nonverbal cues to stop the misbehavior without disrupting the rest of the class. If two students are talking during a presentation, then stand near them to let them know that you are aware of their misbehavior. Often close proximity is all it takes to stop bad behavior. A tap on the shoulder or a stern look will also work to stop inappropriate behavior without disrupting the entire class.
If a student's misbehavior is very disruptive, then you may need to remove that student from the classroom. Do not talk to the student in front of the class, as this will cause her unnecessary embarrassment. Likewise, do not try to talk to a student while either of you is angry; either of you may say something out of anger that you will regret. Instead, remove the student from the activity and take her to a quiet place where she can cool off and regroup. Wait until you have both calmed down before addressing the issue.
Once the student is calm, find a quiet place where you can talk without other students overhearing or interrupting. Give your student a chance to explain his behavior. Listen to what he has to say, and do not interrupt. Do not make the student feel rushed; take the time to listen. Once you have heard his explanation, talk about why the behavior was unacceptable and explain the consequences for that behavior. Stay positive during the conversation.
