Classroom management refers to things teachers do to organize students, space, time and materials.
Task-oriented and predictable environments are where students know what is expected of them and how to succeed. There should be no wasted time, confusion, or disruption. The environment is work-oriented, but relaxed and pleasant. Effective teachers are no different than ineffective teachers in responding to and dealing with students' misbehavior after the misbehavior occurred. Your reputation precedes you.
