The Portsmouth Project attempted to develop a consciousness in teachers of how they acted in their own classrooms and of the effect their behavior had on the learning environment of children. A basic assumption of the program was that teachers will change their style of interacting with students in the classroom if they become more aware of their own behavior. Given an opportunity to examine their own teaching techniques and to form models of desired behavior, teachers will create more effective classroom learning climates for their charges. Not only will the training sessions be positively perceived by teachers, but the modified teacher behavior will have a positive impact on the pupils. The Portsmouth test situation, therefore was designed to provide teachers with such an opportunity to observe, discuss, and analyze themselves and others on video-tapes. The solution to eradicating disciplinary practices detrimental to learning seems to the authors to rest in providing teachers with systematic training in classroom management. The format of the training sessions was designed to provide teachers with these opportunities through observation, discussion, and analysis of video tapes. Not only will the training sessions be positively perceived by teachers, but the sessions will also have a positive impact on the pupils. (Author/JM)
