This instructional package is one of three designed for educable mentally impaired students in the vocational area of building maintenance and engineering. The thirty-one learning modules are organized into nine units: grounds; sanitation; boiler maintenance and operation; power and hand tools; cabinet construction; repair of damaged furniture; windows; and door maintenance. Each module includes these elements: a performance objective page which tells the student what will be learned, what materials are needed, and what the student must do in the module; and a job step page written in a read (cognitive information), look (graphic illustrations), do (instructions), and check (student is evaluated by teacher) format. (This document and related documents CE 017 564 and CE 017 563 are one of four sets of learning modules on maintenance and engineering. The other three sets are written in formats designed for regular vocational, visually impaired, and low-reader students. The modules are part of a total set of over 1,300 modules written for different student populations. Graphics, dietetic assistant, small engine repair, and medical assistant are the other vocational areas covered. CE 017 554 is the final report of the project to develop the modules.) (JH)
