This handbook was designed to assist local Teacher Corps projects to plan and implement the Teacher Corps'"Fourth Outcome:" the adoption or adaptation of the project's educational improvement activities by other educational agencies and institutions. Section I provides an overview of seven scenarios which might be applicable to local projects planning to adopt or adapt other projects. The descriptions were drawn from an analysis of Teacher Corps proposals, literature, and conversations with researchers and practitioners. In Section II, five of the scenarios are expanded into experience-based essays that can be used by staff in a variety of programs to clarify implementation and institutionalization goals. The five scenarios involve: (1) district-wide adaptation/adoption strategies; (2) using a "shadow school" approach in field testing; (3) utilizing existing linkage systems; (4) collaboration with the state education agencies; and (5) federal dissemination mechanisms for products and practices. Worksheets are included for developing a scenario that is site-specific to project staff. The four chapters in Section III provide guidelines to achieve the goals of the Fourth Outcome at local project sites. The techniques discussed are assessing the project, targeting audiences, using audience interaction in decision making, and evaluating Fourth Outcome results. A selected, annotated bibliography of documents pertaining to the adoption of Teacher Corps improvements comprises Section IV. A list of the contributors is appended. (FG)
