THE EFFECT OF FEEDBACK OF ACTUAL AND IDEAL BEHAVIOR RATINGS BY HIGH SCHOOL TEACHERS ON THEIR DEPARTMENT CHAIRMEN WAS STUDIED. IT WAS HYPOTHESIZED THAT SUCH INFORMATION WOULD INFLUENCE THE BEHAVIOR OF DEPARTMENT CHAIRMEN IN WHAT THEIR TEACHERS DESCRIBED AS A DESIRABLE DIRECTION. THE VARIOUS REQUIREMENTS OF THE EXPERIMENT WERE COMPLETED BY 208 SOCIAL STUDIES DEPARTMENT CHAIRMEN AND APPROXIMATELY 2,300 SOCIAL STUDIES TEACHERS. THE TEACHERS RATED THEIR CHAIRMEN ON 10 ITEMS OF BEHAVIOR. A BOOKLET PROVIDED THE FEEDBACK TO THE CHAIRMEN OF THE ACTUAL AND IDEAL RATINGS. THE CHAIRMEN WERE RANDOMLY ASSIGNED TO THREE GROUPS--(1) A PRETEST, IMMEDIATE FEEDBACK, AND POST-TEST EXPERIMENTAL GROUP, (2) A PRE- AND POST-TEST CONTROL GROUP, AND (3) A POST-TEST ONLY CONTROL GROUP. THE DATA SUGGESTED THAT THE ROLE OF CHAIRMEN WAS ILL-DEFINED AND THAT THE CHAIRMEN DESIRED TO BE MORE PROFESSIONALLY INVOLVED THAN CONDITIONS ALLOWED. RESULTS SHOWED THAT THE TOTAL EFFECT OF FEEDBACK ON SOCIAL STUDIES CHAIRMEN WAS LESS SIGNIFICANT THAN EXPECTED. (RS)
