This conceptual framework was constructed by researchers with the Diffusion Program at the Center for Vocational and Technical Education for the purpose of classifying research findings on dimensions of the diffusion process consistent with the objective of the program; the formulation of rational strategies for diffusion of innovations in vocational and technical education. Data collection procedures included analyses of commissioned papers, ERIC documents, and reports of diffusion research. A group of innovative project directors were interviewed, and a committee of consultants reviewed and revised the framework. Target audiences for this conceptual framework are diffusion researchers, change agents at the state or local level who need information on available tactics for innovation diffusion, consumers of innovations, and university faculties preparing education extension or other change agents. The framework presented in this document represents the first of a planned 3-year activity. Appendixes contain the preliminary framework subdimensions, consulting committee group reports, list of innovative project directors interviewed, and an outline of a handbook of diffusion techniques.
