This eighth in a series of eight learning modules on professional role and development is designed to give secondary and postsecondary vocational teachers skill to supervise student teachers in a vocational education program--guiding them through the student teaching experience and evaluating their progress. The terminal objective for the module is to supervise a student teacher while serving as a cooperating teacher in an actual school situation. Introductory sections relate the competencies dealt with here to others in the program and list both the enabling objectives for the four learning experiences and the resources required. Materials in the learning experiences include required readings, a checklist for demonstrating instructional techniques, a case study on the student teacher conference, a vocational student teacher evaluation instrument, and the teacher performance assessment form for use in evaluation of the terminal objective. (The modules on professional role are part of a larger series of 100 performance-based teacher education (PBTE) self-contained learning packages for use in preservice or inservice training of teachers in all occupational areas. Each of the field-tested modules focuses on the development of one or more specific professional competencies identified through research as important to vocational teachers. Materials are designed for use by teachers, either on an individual or group basis, working under the direction of one or more resource persons/instructors.) (JT)
