The rapid growth of educational research and development in America has widened the gap between average classroom practice and "best available" validated practices resulting from research and development at educational laboratories, universities, and school-based practice improvement projects. The extension agent system was chosen to change the educational dissemination system from a passive to an active one. Programs already in existence were studied and personnel functions were extracted to develop models. Job/role descriptions were compiled and divided into selection criteria and teachable knowledge/skills. Finally 28 modules to train project directors, resource personnel and field personnel were developed and tested. This trainers' book consists of lesson plans for each of the modules. A summary description is followed by a list of required materials and aids. Detailed information is given on points to be covered and how to conduct the learning session. Background papers are included with most modules. This document is meant to be used in conjunction with the Final Report (LI004361) and the Trainees' Book (LI004363). (Author/DH)
