This seminar overview presents a summary of widely accepted findings by researchers on the qualities, behaviors, and characteristics of effective teachers. As defined in this paper, an effective teacher is one who can engage students in the learning processes, minimize disruptive behavior, and produce desired learning in a large number of students. In the first section, four generalizations about what teachers do as effective managers of student learners are discussed. These dimensions of classroom mangement include implementing a workable set of rules, structuring and monitoring activities to minimize disruptions, quick and consistent response to misbehavior, and responding to inappropriate behavior without denigrating the student involved. The second section presents eight dimensions of effective teaching, or management of student learning, including: (1) "knowing" students; (2) assigning appropriate tasks; (3) orienting students; (4) monitoring students; (5) relating teaching and testing; (6) involving students in learning; (7) providing continuity; and (8) correcting errors and misunderstandings. In the final section, a discussion is offered on the interrelationships among these dimensions and the complexity of implementing effective teacher behaviors. (JD)
