In a study of Teacher Corps implementation of multicultural education and collaboration components in inservice teacher education programs, four community sites and their schools were studied. This volume presents the case studies of each community in a narrative form. To preserve anonymity, the names of people and places connected with the study were changed. Two of the study sites were rural, and two were urban; all had desegregated schools with complex social and educational situations. The settings are described, including the characteristics of the community, schools, and other educational facilities. The development of the multicultural and collaborative elements of Teacher Corps projects are described, often using sections from interviews or reports by local individuals to relate specific instances. Conclusions are stated for each site along with reviews of the progress and activities connected with the Teacher Corps projects. (FG)
