This document reports on a project undertaken to determine the feasibility of a periodic national survey of a sample of U.S. school districts to obtain information on the performance of the existing dissemination and utilization network for educational innovations. All the cases in this volume were originally identified from a national survey of innovation reported in a representative sample of 353 U.S. school districts and illustrative of innovations attempted in the late 1960's or early 1970's. They are intentionally diverse in content, district size, and geographic locale. The studies presented include the individualized instruction program, the program improvement proposals (PIP), the talented student program, implementation of the middle school concept, and flexible modular scheduling. A selected list of references is included. (Author/DN)
