Why should I do it:

• The more distance between teacher and student will result in more behavior problems
• Can be used to communicate care and concern
• Can be a subtle re-direction technique
• Lets the student know you are aware of them

How do I do it:

• Pay attention to your natural movements and determine areas you can change your style to increase proximity to many students at once
• When giving directions, maintain proximity to at risk students
• Refrain from giving instructions the same way every time
• Vary your teaching that will allow you to walk around the classroom
• Place a student close to you in seating arrangements
• Proximity control can work to manage some behavior if it is used preventively or early.  The main idea behind this technique is to put a teacher in close proximity to students who are showing signs of getting off task. If you know from prior experience that a particular group of students is likely to disrupt class, standing or sitting close to them while you lead an activity or give directions will quell a fair amount of the unwanted behavior.
