This document contains supplemental materials for special needs high school students intended to facilitate their mainstreaming in regular auto mechanics courses. Teacher's materials precede the materials for students and include general notes for the instructor, suggestions, 18 references, a class progress chart, a questionnaire on the usefulness of the supplemental materials, and an answer key to student work sheets. The student materials consist of 10 color-coded instructional units on the following topics: using service and shop manuals; safety, preventive maintenance inspection; checking tire and wheel runout and tire balancing; checking and repairing shock absorbers; checking and replacing MacPherson struts; using meters to test wiring and switches; testing a charging system; testing the cranking system; and troubleshooting an electronic ignition system. The units are self-paced and contain simplified line drawings, controlled text, vocabulary development, and math practice exercises. The units typically include the following materials: (1) an introduction; (2) the objective of the unit; (3) the objectives on which students will be assessed; (4) terms and pictures of equipment used in the unit and on the job; (5) verbal and illustrated step-by-step explanations of a skill or task; (6) skill sheets that contain paper and pencil exercises that develop and reinforce math skills; (7) activity sheets designed to increase student involvement and provide extra skill practice; (8) unit reviews involving identification, matching, multiple-choice, and short-answer exercises; and (9) checklists on which to evaluate student performance.
