THIS FINAL REPORT OF A SERIES ELABORATES DATA FROM REPORT I IN SIX INTENSIVE CASE STUDIES OF THREE TYPES OF GIFTED ADOLESCENTS (CREATIVE INTELLECTUAL, STUDIOUS, SOCIAL LEADER) IDENTIFIED BY SELF-REPORT, AND TESTS THE STRENGTH AND DURABILITY OF ATTITUDE CHANGES RESULTING FROM CURRICULUM EXPERIMENTS DESCRIBED IN REPORT II. RESEARCH RELEVANT TO THE CREATIVE INTELLECTUAL STYLE IN BOTH ADULTS AND ADOLESCENTS IS CITED. ASSUMPTIONS THROUGHOUT THIS RESEARCH ARE THAT EDUCATIONAL AIMS FOR GIFTED ADOLESCENTS SHOULD INCLUDE DEVELOPMENT OF IDENTITY, MOTIVATION TO LEARN, AND OPENNESS TO CHANGE. FORMAL AND INFORMAL MEASURES ON TESTS ADMINISTERED ONE YEAR AFTER THEY WERE GIVEN FOR REPORT II EXPERIMENTS SHOWED CONTINUING TRENDS OF ATTITUDE CHANGES TOWARD CREATIVE INTELLECTUALITY FOR ALL POPULATION SUB-GROUPS, BOTH EXPERIMENTAL AND CONTROL, BUT NO APPARENT INCREASE IN PROBLEM-SOLVING SKILLS. THESE RESULTS ARE FURTHER DISCUSSED IN THE CONTEXT OF THE CASE STUDIES, AND IN TERMS OF CONCURRENT SOCIAL TRENDS. (LH)
