Effective classroom management requires structuring the environment, actively supervising students, implementing clear rules and routines, and encouraging appropriate behavior. The classroom should have an organized physical layout, make efficient use of time, and foster positive student interactions. The teacher should scan the room, have mostly positive interactions, provide opportunities for students to respond, and engage students through various methods. Rules should be minimal, simple, positively stated, and consistent, while routines allow the class to run smoothly. Clearly communicating behavioral expectations, examples to replace inappropriate actions, teaching and practicing them helps encourage pro-social behavior. Collecting data on student performance and attitudes allows the teacher to monitor behavior and modify procedures as needed.
