This study was an attempt to build upon the prior work in the area of the diffusion of innovations and innovativeness. Broadly stated, the study attempted to answer the question: What is the relationship between selected characteristics of intact groups and their innovativeness? The sample consisted of six elementary schools in Massachusetts which reported having adopted team teaching within the past two years. Staff members (130) of these schools provided information about the communication network and informal organization of their school as well as personal data. This data were related to four measures of innovativeness based on the within-group diffusion of team teaching. Findings were mixed, but in unanticipated finding indicated the vital role of the elementary principle as an agent of change. Independent research found that the most innovative school also possessed an "ideal" learning environment as perceived by its students. The techniques utilized offer a practical vehicle for initiating meaningful change within schools. (BW/Author)
