In 1984 the Urban Mathematics Collaborative (UMC) project was initiated to improve mathematics education in inner-city schools and to identify new models for meeting the ongoing professional needs of teachers. UMCs are located in Cleveland, Minneapolis-St. Paul, Los Angeles, Philadelphia, San Francisco, Durham, Pittsburgh, San Diego, St. Louis, Memphis, and New Orleans. In addition, two other projects were established: a Documentation Project to monitor the activities of the new collaboratives and a Technical Assistance Project to serve as a source of information for the collaborative projects. In each of the 11 cities, the UMC project supports collaboration among groups of mathematicians from high schools, higher education institutions, and industries, and encourages teacher participation in a broadly based local mathematics community. This report presents an overview of the efforts of the UMC project as a whole, as well as a brief description of each of the collaboratives and the Technical Assistance Project. The Appendix of the report includes a detailed progress report for each of the projects for the 1986-87 school year. (PK)
