The first part of this document provides a brief account of a project to develop learning modules on the microcomputer and the microscope for use with limited English-proficient speakers of other languages who are enrolled in vocational education courses. The bulk of the document consists of appendixes presenting the modules themselves. The microcomputer modules, which were developed in English and then translated into Spanish, Vietnamese, and Korean, cover the following microcomputer components/accessories and their uses: printed circuit boards, floppy disk drives, floppy disks, visual display screens, printers, computer printout paper, ribbon cables, graphics, graphics pads, lightpens, sensitive boards, modems, and pocket computers. The definition of each component is illustrated by a graphic as it could appear on the accompanying audio tape. The two modules on the structure of a microscope, which are supplied in English, Vietnamese, and Spanish, deal with the way in which objects are magnified, the history of the microscope, microscope lenses, and the parts of a microscope. Each learning experience includes learning activities, a self-check exercise, and a feedback activity. (MN)
