Dealing with behaviour is critical to your classroom success. Generally most students want to behave and very few really want the tension of getting into trouble. If you want an easier time in dealing with behaviour, when you give instructions, anticipate that the student will comply and act as if this is the case.
When you are dealing with behaviour you really only want the kids to comply with your requests.
I call them requests, but they could be instructions, directions or demands. Whatever, you just want the kids to comply.
So what about if you anticipate compliance when you are dealing with behaviour?
For example, in your travels around the room you notice Gina is reading a book and not doing her math. You take the least intrusive path, “Thanks for putting that book away, Gina.” (NB – Closed request - a closed request doesn't give the student a chance of reply) Continue to move around the room dealing with behaviour as you go and act as if you know Gina is going to comply with your instructions.
Close your request. You can close off a request by prefacing your statement with an expectation of compliance. Such statements like “Thank you for closing the windows for me, Paul”. Few students are likely to refuse a request phrased in such a way.
Gina feels your expectation and 99.9% of the time she will comply. She is not going to get any mileage if she doesn't because you have already moved on!
Consider the alternative action when dealing with behaviour in a different way.
Let's assume you say the same thing, but instead of anticipating compliance, you stand at Gina’s desk with arms on your hips and a snarl ready on your lips. You are ready for a fight and Gina is likely to accommodate you.
