While materials for teaching for intergroup understandings in the form of books, curriculum guides, and articles are widely available for direct implementation into ongoing curricula, the actual development and implementation of this type of material into school programs has usually been reserved for specifically designated national dates. However, the authors of this paper were invited, in January 1971, to assist four sixth-grade teachers who wished to "teach something about other people to our children," although not committed to engaging in a research project designed to assess the effects of their instruction during the implementation of the unit. The entire sixth-grade class of 86 served as the experimental group and another school's entire sixth-grade class was secured as the control group. Both groups were given a pre- and post-test using the Paired Hands Test. The experimental "treatment" was sequenced into eight increasingly interactive steps: panel discussions, film-strip presentations, buzz sessions, open-ended stories, discrimination day, field trip to an all-white inner city school, field trip to an all-black inner city school, and a cooperative, three-school skating party and luncheon.
