This paper reviews objectives, methodology, and data analysis procedures of a study concerning educational innovation. This research, part of the Procedures for Adopting Educational Innovations (PAEI) Program at the University of Texas at Austin, was undertaken to study interventions and their effects. It was considered a first step in determining what actions can be taken to assist individuals in their efforts at implementing an innovation. The initial objective of the research was to develop a taxonomy of interventions. The particular innovation looked at in the study was a Teacher Corps Project located in a junior high school in a university town. An onsite ethnographer documented interventions at the site and these data were utilized to conceptualize and characterize the emerging taxonomy of interventions. Tentative classification categories were defined using field data. In accomplishing this task, definitional and conceptional issues were the focus of dynamic interactions of the program staff with each other and with the qualitative and quantitative data. A procedure was developed for reducing the data and at the same time isolating each intervention for further study. (Author/JM)
