This module is one in a series of 127 performance-based teacher education (PBTE) learning packages focusing upon specific professional competencies of vocational teachers. The competencies upon which these modules are based were identified and verified through research as being important to successful vocational teaching at both the secondary and postsecondary levels of instruction. The modules are suitable for the preparation of teachers and other occupational trainers in all occupational areas. Each module provides learning experiences that integrate theory and application; each culminates with criterion-referenced assessment of the teacher's performance of the specified competency. This module is designed to help prospective teachers identify and use techniques that will improve their ability to communicate orally with students as they make both large and small presentations. The module consists of a terminal objective and enabling objectives, prerequisites, resources, and four learning experiences. Learning experiences, which focus on the enabling objectives, contain an overview, information, activities, self-checks, lesson presentation checklists, and feedback. The final learning experience is an actual teaching situation in which the prospective teacher is to present an illustrated talk and be evaluated by a resource person on his/her competency in this task.
