Learn your school's policies on misbehaving students. Each school is different, so make sure you understand what the school requires of you in a situation and when it is time to ask for assistance.
Set a good rapport with students on the first day of school. Explain that the most important rule of your classroom is respect. Students should respect you and their classmates, and you should respect the students.
Ask students to help you create a list of both proper behaviors and those that would require some disciplinary action, and decide a punishment suitable for each inappropriate offense. Allowing students to help create the rules makes them more accountable for their daily behaviors. Post those rules in the classroom.
Use proximity control, or closeness, to calm a misbehaving or unfocused student as soon as you notice the behavior. Just walking by or standing beside the student is often enough to stop any further disruption if the problem is addressed quickly.
Quietly ask a disruptive student to focus on whatever task should be happening, whether listening to your directions or completing an independent or group assignment. Just saying the student's name can help by making him aware that you notice the behavior and do not approve.
Tell a disruptive student to leave the classroom and wait for you in the hallway if the behavior is becoming bothersome or disrespectful to others. This removes the problem from the classroom so that the learning environment for other students may be restored. Finish giving directions, distributing papers or helping students before you go to the hallway.
Privately ask the student why he believes you asked him to step outside. Discuss why the behavior was inappropriate, guiding his response with questions. When you are satisfied that the student understands, ask him to return to his seat to complete his assignment.
Seat the student in a corner area away from others or in the hallway if disruptive behavior continues, and call home after school to let the parents or guardians know what has been happening.
Refer the student to the disciplinary personnel in your school, if disruptions persist. Those personnel have procedures for dealing with continual bad behavior and may be able to help you ease the student back into class.
