Following nine hours of training in behavioral psychology, the faculty members of an 800 pupil elementary school were applying operant techniques with no further apparent need of consultation with the instructors. Twenty-two teachers were enrolled in an inservice training course entitled "Behavior Modification Procedures for the Elementary School Teacher." Teachers were shown color slides illustrating actual classroom use of operant conditioning procedures, were asked to count their own verbal praise for a twenty minute period each day during the course, and were required to prepare a transparency showing daily count of pinpointed child behavior the teacher was dealing with (hitting, talking spontaneously, leaving seat, thumbsucking, etc). As the sessions progressed, teachers began consulting and working together on group contingencies and children they instructed in common. Group discussions, positive attitudes among the teachers, visual representation of behavior change, increased praise of satisfactory behavior and teacher cooperation were the contributing factors to the success of the program.
