This study compared local 4-H Club leaders (Negroes in Alabama and whites in Wisconsin) on knowledge gained when films or bulletins were used in training meetings. It also sought to compare the effectiveness of films and bulletins, with or without discussion, following presentation of research findings to the Negro leaders; to assess changes in the Negro leaders' knowledge after exposure to such data; and to compare the effectiveness of local and professional discussion leaders. The local leaders appeared more effective than the professionals. There were no differences in Negro leaders' knowledge gain between films and bulletins, or between professional and local leadership of discussion. Negro leaders' education was positively related to gains. Given similar methods of presentation, the Wisconsin leaders surpassed the Alabamians. The Alabama group gained in knowledge when presented with research findings, but the amount of gain depended greatly on educational background. (author/ly)
