Avoid, to the best of your ability, congested aisles and stumbling blocks to easy access of supplies. Often, when students are placed in close and uncomfortable contact, flare-ups become common. Moreover, teachers should be able to see each student, and each student should be able to see the teacher. It also helps with early targeting and early intervention by accurately identifying troublemakers. Teach your classroom procedures as if they were curriculum.
Procedures change from class to class, based on teacher style.
Students should know how to function in each class. Your school should already be supplying training and policy information about this, especially in view of current increases in mainstreaming and inclusion. If not, contact your local union representatives and ask them to work with the administration to make this kind of training available. Rules governing what you can or cannot do to discipline special education students who have committed the same infractions as regular education students can be different. This can cause havoc in the classroom or on the school bus.
