A survey of teaching practices and a face-to-face sharing institute were designed for an experiment to identify innovative practices, to legitimize the sharing of them, and to develop criteria for evaluating the relevance and importance of particular inventions. This experiment was part of a project involving a state organization of teachers and teams of teachers in local school systems in which the former provided an organizing link and the latter acted as researchers and disseminators. A questionnaire discovered new educational practices which were evaluated by a rating scale especially developed for the project. Documentary descriptions of each nominated practice were placed in a catalogue and distributed to participating schools. The teachers' response to the catalogue was measured by a postcard questionnaire. A forcefield analysis of the factors supporting and hindering active innovation resulted in a sharing institute focused on the resistance to diffusion. The objectives, design, operation plans, and program outline of the institute are followed by staff observations. Three nominated teaching practices, the rating scale, a documentary description from the catalogue, and the forcefield analysis are reproduced. (Author/KSM)
