Proactive classroom control begins with setting the tone in your room in the first few minutes before behaviors can become problems. If you miss the opportunity for a smooth, controlled start, you will spend more of your time trying to calm things down and regain control. By following a routine that the students can count on, a proactive teacher can head off many discipline problems that more reactive teachers face daily. For example, students arrive to class over the course of several minutes, but the children go right to work on a daily start-up activity when they enter the room (i.e. LEGO Building). As the reactive teacher’s classroom fills up, students are talking, joking, and waiting for class to start. Each period, each day the reactive teacher has to break their momentum, cut through the energy, and pull his students onto the task. When the bell rings, the proactive teacher’s class has been on task for some time, while her colleague is already in a reaction mode, trying to settle his students down. If a student appears to be becoming frustrated, intervene as soon as possible in order to prevent the misbehavior from occurring (e.g., say “Harry, may I help you with your assignment?”).
