The document summarizes research on the process of diffusing innovations in vocational education. The purpose was to: (1) determine if empirical dimensions of three conceptual domains (innovation, client, and strategy) exist; (2) if they exist, to identify them; (3) to describe them with empirical information; and (4) to relate the dimensions to perceived effectiveness of diffusion tactics. An interim report described the innovation and client domains; the final report identifies types of diffusion tactics and relates selected variables (types of diffusion tactics, types of clients, stages of adoption, and types of innovations) to the perceived effectiveness of these tactics. Stages of adoption are identified as awareness, interest, evaluation, and adoption. The most important finding of the study was a significant difference in the perceived effectiveness of diffusion tactics across all stages of adoption. The ratings for stage of adoption was different across all tactics. The interaction of these two variables was also significant. Individuals in the client clusters perceived tactic effectiveness differently. Respondents in different roles tended to perceive tactic effectiveness differently. These findings empirically document the need for differential use in educational change tactics for persons in different roles and for projects in different stages of adoption. (Author/AJ)
