Good classroom management is proactive, not merely reactive. Effective classroom managers anticipate problems before they arrive, and set the expectations for student behavior clearly and explicitly before giving direction. For example, a teacher will pre-correct students prior to them splitting into small groups by explicitly reminding the class of their routine for getting into small groups, and the behavior expectations for transitions. Linking prompts and precorrections to the schoolwide matrix for behavior expectations reinforces those expectations and creates opportunities to praise students for positive behavior.
