Effective teachers view classroom management as a process of organizing and structuring classroom events for student learning. Creating a well-managed classroom with established procedures is the priority of a teacher the first two weeks of school. In an elementary classroom where each day may have a different array of subjects and at different times during the week, an organized classroom management plan is a teacher's most influential and effective tool and is the primary determinant of how well the students will learn. This includes science lessons that may have the same procedures used in other subjects, such as getting into groups, respecting each other's turn to speak, collecting and returning materials, and starting and remaining engaged in the lesson's task. When a classroom is well-managed with procedures, there is little downtime and learning is productive. The students are motivated and on task, and the climate of the classroom is work-oriented but relaxed and pleasant. The school year flows smoothly with the teacher and the students experiencing success. (Contains 2 figures.)
