The project described in this report was conducted at Temple University (Pennsylvania) to design a collegial process and the necessary instructional materials to enable the practicing vocational educator to engage in professional development with a commitment to a formative approach. The project attempted to bring inservice vocational teacher certification programs in the state in close approximation with school-based "induction" and "continuing professional development" programs. During the project, a process was developed and built into the present certification program to facilitate a formative approach and serve as a bridge between level I and level II certification. Instructional materials (modules) were developed for use in Temple's existing vocational teacher certification program and vocational teacher educator staff development program. Temple teacher education faculty and staff were trained in the process, which was pilot tested at selected field sites in eastern Pennsylvania. The modules developed in this project make up a large portion of this document. The modules focus on (1) developing a lesson plan to guide group instruction, and (2) facilitating a Council of Educators' review. Each module lists objectives, prerequisites, resources, learning experiences/activities, and level of performance assessment instruments. (KC)
