A model of teacher behavior and interaction with students was designed using the results of the Questionnaire for Interactional Teacher-behavior (QUIT). Responses were obtained from 91 teachers and 2407 secondary school students. The questionnaire measured teacher behavior, as seen by the teacher and by the students, on scales that ranged from dominance to submission and opposition to cooperation. Case studies were investigated using this model of teacher behavior and teacher-pupil interaction, and these studies resulted in "maps" of interactional teacher behavior and teacher-pupil interaction that illustrated the over-all environment of the classroom. Discussion is presented about modification of teacher behavior and attitudes during the professional career, from beginning teacher to more experienced teacher. The teachers' ability to create a favorable working climate is explored. Two types of disorderly classroom situations and accompanying teacher behavior are described. One involves an aggressive and confrontational teacher dealing with an unruly classroom, the other a cooperative and tolerant teacher dealing with a similar situation. (JD)
