Realizing that most teachers are quite adequate in their own background of knowledge and skills, sensing the growing threat to students and teachers of the impersonalization and isolation in many crowded classrooms today, the In-Service Training Program Emphasizing the Affective Dimension was innovated at Wheeling High School, Illinois, during the 1967-68 school year. The main objectives were: (1) to expose teachers to situations which would result in their being willing to look at their own behavior and its effect on the atmosphere as well as the behavior of the group, (2) to develop in the teachers an increased desire to consider each student as an individual, and (3) to involve the teachers in assessing their own behavior in the classroom setting. Most of the sessions were video-taped. This gave the participants the opportunity to see first-hand the value of video-taping and analyzing their classroom activities. Monthly all-day seminar sessions were held involving three types of seminar groups: (1) for beginning teachers, (2) for second-year teachers who were members of a seminar group last year as beginning teachers, and (3) for "veteran" teachers. Membership of each group represented all disciplines and remained the same throughout the year in order to build a strong expansion of the program to involve five of the six high schools in District 214 is now in process.
