This module is one of 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 preservice and inservice preparation of teachers and other occupational trainers in all occupational areas. This module contains four learning experiences that are designed to help teachers/student teachers to acquire skill in working with the people who are responsible for providing the on-the-job instruction for students in a cooperative work-experience program and developing the instructional effectiveness of these personnel. Each learning experience contains an objective, several activities, information sheets, resource lists, and a self-check with model answers. The final learning experience requires the teacher/student teacher to demonstrate competency in applying the material of the module in an actual teaching situation. (KC)
