This report deals with the research and development of a curriculum which seeks to advance democratic intergroup relations through educational processes in elementary schools. Volume 1 describes the background research and development, with particular emphasis on propositions, critiques, and recommendations with respect to intergroup relations education in the United States. It also contains a report on the Lincoln Filene Center's inservice program for teachers, evaluation instruments, and procedures for disseminating information and findings regarding the curriculum, as well as instructional materials and teaching strategies. Intergroup relations are defined as interactions among people which reflect a respect for human dignity and worth and which seek to avoid prejudicial thinking and overt discriminatory behavior. A large number of preconceptions are examined, and supportive research and evidence are cited for the positions taken by the Center in developing the curriculum. Volume 2 of this report is related document SP 005 479. (MBM)
