This is Volume II of a two-volume final report of a study on the exchange and use of knowledge for school improvement in three paired educational systems in Boston, Massachusetts. The pairings, which involved the collaboration of a college/university with one or more of the Boston public schools in carrying out school improvement programs, were among 26 such collaborative arrangements mandated by court order in 1975 as part of Boston's desegregation program. The first volume of the report provides background information, describes the conceptual model and methodology used in the study, and summarizes conclusions and recommendations. This volume contains reports on the case studies of the three paired svstems. The pairs investigated were: (1) Harris University-District A; (2) Massachusetts College-District B; and (3) Dunfey University-District C. Each case study describes the paired institutions and their settings, explains the study methodology, describes projects studies in each paired system, provides a cross project analysis of the collaborative processes involved, analyzes the nature of roles/functions that evolved from the collaboration, and examines factors that contributed to program success. The case studies conclude with a discussion of the types of knowledge exchange that occurred within the pairing-sponsored projects. (Author/MJL)
