THE OBJECTIVES OF THE STUDY WERE TO--(1) INTRODUCE SOUND FILMSTRIPS AS AUDIOVISUAL AIDS FOR INSERVICE TEACHER TRAINING AND (2) EVALUATE AN INSERVICE PROGRAM IN TERMS OF CHANGES IN SPONTANEOUS TEACHER BEHAVIOR. FIFTY-ONE TEACHERS (DIVIDED INTO TWO GROUPS OF AN INSERVICE TRAINING PROGRAM) WERE OBSERVED IN THE FALL BEFORE PARTICIPATING AND IN THE SPRING AFTER THE PROGRAM. RESULTS SHOWED THAT THE TEACHERS WHO HAD THEIR OWN IDEAS AND COMMENTS INTEGRATED INTO THEIR PROGRAM--(1) ENGAGED IN MORE EXPERIMENTATION AND (2) APPLIED MORE INDIRECT, OR FLEXIBLE, PATTERNS OF TEACHER INFLUENCE IN THEIR CLASSROOMS. BY USING INTERACTION ANALYSIS ON TEACHER ACHIEVEMENT AND ATTITUDE, IT WAS DETERMINED DESIRABLE TO HAVE A FEEDBACK TO ASSESS THE DEGREE OF TEACHER INFLUENCE. IN ADDITION, THE MOST CONSTRUCTIVE TEACHER INFLUENCE APPEARED WHERE THERE WAS AN OPPORTUNITY FOR INDEPENDENT AND SELF-DIRECTED INQUIRY IN THE CLASSROOM. THE INFLUENCE OF SUCH OTHER FACTORS AS MORALE AND PRESENTATION CONDITIONS PREVENTED EVALUATION OF THE FILMSTRIPS IN ANY ABSOLUTE SENSE. (PM)
