Presented in the third and final evaluation report (1975-76) of Project Talented and Gifted are results of an appraisal of over 50 student participants (8-15 years old) and the project staff and resource personnel. The project is described as a 3-month institute to provide experiences in areas such as learning to use creative thinking and problem solving strategies in language arts, science and mathematics, and music. Results and recommendations from the first and second evaluations are outlined in Part I and the methodology of the study is described, with additional information on design, experimental treatment, and statistical analyses. Part 2 presents analyses of the student participants' creative self-perceptions as reported in the first and second evaluation, and procedures and results from the final evaluation. Included in Part 3 are data generated by students and parents, resource people, project coordinators, and the director. Part IV covers summary conclusions indicating non-support of the effectiveness of the program by experimental evidence, but support of the effectiveness of the program in the areas of cognitive and affective growth by observational evidence; and recommendations such as basing selection of gifted students on their exhibited talent, adopting elements related to the teaching of specific problem solving techniques and research strategies, and requiring facilitators to attend a problem solving institute.
