This last in a series of six learning modules on instructional evaluation is designed to give secondary and postsecondary vocational teachers help in identifying the sources and techniques needed in order to plan a method of teacher evaluation which is logical, usable, and capable of improving teaching performance on a continuing basis. The terminal objective for the module is to evaluate your instructional effectiveness in an actual school situation. Introductory sections relate the competency dealt with in this module 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, case study to critique, model critique, and the teacher performance assessment form for use in evaluation of the terminal objective. (The modules on instructional evaluation 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.) (EM)
