The Research and Development Utilization (RDU) program research component examines the successes and administrative dilemmas faced by demonstration projects that attempted to develop interorganizational networks in a knowledge utilization and school improvement process. A framework is presented for looking at RDU projects as a group of interorganizational networks. Issues relevant to the design, management, effectiveness, and institutionalization of such networks are discussed, focusing on networking as a strategy for knowledge utilization in general, and for RDU in particular. Chapter-length case studies of four RDU projects examine the networking strategy in greater detail. These cases are then synthesized in the final chapter, and the lessons learned about networking are summarized for the future design and management of educational linkage systems. (Author/MLF)
