This seventh in a series of twenty-nine learning modules on instructional execution is designed to give secondary and postsecondary vocational teachers skill in assisting student development of laboratory work plans, in guiding student progress through the use of these plans, and in developing special instructional materials for use in the laboratory, such as job sheets, operation sheets, and information sheets. Introductory sections relate the competencies dealt with here to others in the program and list both the enabling objectives for the three learning experiences and the resources required. Materials in the learning experiences include required reading, self-check quizzes, model answers, performance checklists, case studies to critique, model critiques and the teacher performance assessment form for use in evaluation of the terminal objective. (The modules on instructional execution are part of a larger series of 100 field-tested performance-based teacher education (PBTE) self-contained learning packages for use in preservice or inservice training of teachers in all occupational areas. 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.) (BM)
