Effective teachers are selective and specific in their rules. Classroom rules should be written in a concise, logical and positive way. Rules should be short, clearly stated and visible in the classroom. Rules should be established at the beginning of the year and reviewed as needed. Consequences should also be posted in the classroom. Teachers should make sure all students understand the rules as well as the consequences. Knowing and understanding the consequences ahead of time is paramount to improved cooperation and achievement (McGinnis, Frederick, & Edwards, 1995). Parents should also be made aware of the rules and consequences so that they understand and support the teacher.
