Research has identified several aspects of effective teacher behavior, as measured by student performance. Three aspects of effective teacher behavior are in the areas of instruction, management, and acceptance. Instructionally, teachers should try to provide more variety to deal with different learning styles; they should ask purposeful questions of all students, and they should be aware of the goal structure of their classes. With regard to classroom management, teachers should be more aware of their nonverbal behavior which fosters students' on task behavior, e.g., moving around the class and checking with students while they are doing seatwork. Teachers should also provide clear transitions from one subject to another, structuring comments that tie instruction to a meaningful whole, and a fair set of rules applied equitably to all. Equally important for all students is a feeling of acceptance--a feeling of self worth. This can be achieved through feedback on the teacher's part. Feedback can be positive or negative, but it is necessary for providing direction for academic performance and helping to maintain on task behavior. (JM)
