This scope and sequence guide, developed for a diesel mechanics 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 three-year course of study begins with a presentation of the rules of safety and progresses to the use of tools and equipment in the diagnosis, service, and repair of diesel-powered equipment. The course covers diesel engines, transmissions, power trains, and accessory equipment. A unit of welding and machine shop is included. (KC)
