This scope and sequence guide, developed for an air conditioning, heating, and refrigeration vocational education program, represents an initial step in the development of a systemwide articulated curriculum sequence for all vocational programs within the Metropolitan Nashville Public School System. It was developed as a result of needs expressed by teachers, parents, and the business community for sequential structure within the vocational education curriculum. The guide contains an introduction, course description, general course objectives, course content (with specific objectives) in outline format, and a list of resource materials, such as textbooks, curriculum guides, and audiovisual aids. This course is designed to prepare students for employment in the air conditioning, refrigeration, and heating industry; to provide students with the skills and knowledge necessary to install, service, plan, and estimate types of air conditioning, refrigeration, and heating systems; and to develop manipulative skills relevant to the trade. The course provides students with opportunities to participate in Vocational Industrial Clubs of America (VICA) leadership training, and in local, state, and national skills competition. (KC)
