Organized in question and answer format, this guide is designed to orient both preservice and inservice vocational teachers to performance-based teacher education (PBTE) materials developed by the Ohio State University Center for Vocational Education. The materials are described as a series of 100 modularized learning packages focusing upon the specific professional competencies needed by vocational teachers in all vocational service areas and occupational specialties. Part 1 defines performance-based teacher education in general. Part 2 briefly outlines the rationale and development of the 100-module PBTE series and its research base. Part 3 describes the modules, each of which contains background knowledge, application and/or practice activities, and an opportunity to demonstrate the competency involved in a classroom setting. Suggestions are provided for use of the modules on either an individual or a group basis under the direction of one or more resource persons (instructors). A glossary of PBTE terms and a list of the 100 modules are included. (Each of the modules is available separately.) (JT)
