This manual is designed to provide support for workshop leaders--science supervisors, staff developers, principals, school change agents, and university instructors--who work with preservice and inservice teachers. The goal of the project was to develop a series of workshops that could support teachers of grades four to six as they shift to an increasingly hands-on, project-based approach to science learning enhanced with technologies such as telecommunications and microcomputer-based laboratories. Topics include Reflecting on Practice, Microcomputer-Based Laboratories, Telecommunications, and Bridging to the Classroom. Resource materials for science background, technology background, and other useful information are also included. Contains approximately 70 references. (JRH)
