This instructional package, one of two designed for low reader-educable mentally impaired students, focuses on the vocational area of small engine repair service. (Low readers are identified as those at a reading level of grades 3-6.) Contained in this document are fifty learning modules organized into twelve units: sharpening and grinding mowers; test equipment; motorcycles; engine removal and replacement; machining; tune-ups; short blocks; storage; filling out forms; ring and piston service; valve service; and overhaul. Each module includes these elements: a performance objective page that describes what the student will learn, materials needed, and how performance will be evaluated; information pages including special material not incorporated into the job steps; and job step pages which detail the steps necessary to do the task. (This document and CE 017 581 are one of three sets of learning modules on small engine repair written in formats designed for low reader-educable mentally impaired, visually impaired, and regular vocational students. These modules are part of a total set which includes over 1,300 modules written in a variety of formats on building maintenance, dietetic assistant, small engine repair, medical assistant, and graphics.)
