This study explored two group treatments, humanistic and social modeling, in helping teachers to be more open and helpful in the classroom. Subjects were 42 volunteers from elementary schools who indicated a desire to become more open and helpful. Each of four groups met four times over a 9 day period for 1 1/2 hours. The modeling groups viewed a video tape with detailed instructions of a teacher exhibiting open and helpful behavior. In the humanistic group, members had control over the content and direction of the group. Parts of the Sequential Analysis of Verbal Interaction (SAVI) were used by raters who took a frequency count of statements from 2 hours of classroom session. The Personal Orientation Inventory (POI) was administered at the conclusion of the groups. The results supported both hypotheses: (1) Behavioral modeling can be used to alter open and helpful behaviors of teachers; (2) Self-report measures do not necessarily reflect behavioral change.
