Moving to the part of the room where the inappropriate behaviour is occurring. For most students, it is difficult for them to continue to misbehave when the teacher is so close. In its least intrusive and least confronting form, the teacher stands nearby the student and does not necessarily make eye contact with him or her.
This strategy can be maximise by:
moving closer to the offending student and staying near the student until he/she is back on task.
directly facing the student with hands on hips is more powerful, but is significantly more confronting.
dropping down to eye level at the student’s desk to reinforce the message that the unacceptable behaviour must cease.
NB: for students who display aggressive or oppositional behaviour, the final two dot points can be perceived as very provocative by some students and possibly unwise and counterproductive to use. Please see aggressive and oppositional behaviour for strategies.
