The P. K. Yonge Laboratory School has adapted Havelock's linkage model which explains the knowledge, dissemination and utilization process of dissemination, and implementation of innovations. This study sought to describe the assumptions and strategies of the Laboratory School's Linkage Model and to evaluate the results of the model by focusing on the dissemination of the School's developmental, individualized reading program over a three year period. In the development and dissemination of programs, a five stage process is followed: (1) generating relevant researchable ideas, (2) conducting pilot studies within the Laboratory School, (3) field testing in public schools, (4) information and staff development for public schools, and (5) providing maintenance and support activities. The elements of the linkage model are further analyzed by studying a concrete example. (Author/VT)
