Here are a few proactive measures you can take to get your students to behave appropriately:
1. Make students accountable for their actions. If necessary, use a behavior contract.
2. Make sure that your consequences for behaviors are clearly posted in your room and are not obstructed.
3. Let students know your expectations with regard to their performance as well as to their grades.
4. Keep your cool—do not let students know that they get to you, even though they do. In other words, do not let them see you sweat.
5. Be prepared. If students finish their work in 30 minutes, make sure that you have other assignments ready to go. If you keep them working, they will realize that they do not have time to misbehave.
6. Arrange a conference with the parents of those students who habitually misbehave and disrupt class. If you can rectify the behavior of those recalcitrant students, other students will not be as easily tempted to misbehave.
7. If your school has an online gradebook that parents can access, write comments and let parents know how their student is behaving. This is extremely effective, especially when you know that parents look at such comments frequently.
