The human relations teaching unit suggests materials and activities designed to sensitize students toward racial matters and group interaction of blacks and whites in American society. It is intended for use in an ongoing psychology or related course on the secondary level. The guide recommends that teachers remain neutral introducers of evidence which is to be weighed and evaluated by the students, who are consequently expected to move toward a goal of increased understanding. Units are included on such topics as Minorities and the Police, Minorities and the Employment Agency, The Kerner Commission Report, Discrimination, Freedom Riders, School Bus Incident, and Conditioned Helplessness. The lessons include directions for organizing role playing, field trips, visits by outside resource persons, data collection, volunteer activities, interviews, surveys, studies of ethnic characterizations and population characteristics, plus an extensive bibliography for further study by teachers. Each lesson includes a list of references, "Cautions" and "Follow-up" sections, and behavioral objectives. Step-by-step procedural instructions are given for lessons which are arranged on a one hour per day basis for a period of two weeks. (Author/DB)
