This guide addresses the applicability of microcomputers to adult vocational training and presents guidelines for creating and evaluating software that specifically addresses adult learning needs. The author first discusses the appropriateness of microcomputers as educational and prevocational tools. She highlights those qualities that are the computer's special contributions to the learning process, such as individualization, impartiality, and capacity for routine, and then explains how these features can eliminate barriers to adult learning. Categories of educational software follow, illustrating the use of the computer (1) as an instructional medium, through drill and practice, tutorials, and demonstrations; (2) as a modeling device, through games and simulations; and (3) as a special-purpose, general-purpose, or tool-making (i.e., programming and authoring languages) tool. The remainder of the document outlines the guidelines for software development and assessment, divided into five areas: (1) learning objectives and task analysis, (2) appropriate use of technology, (3) pedagogical considerations, (4) management considerations, and (5) necessity, content, and format for accompanying textual material. In concluding, the author notes the lack of available software that meets these guidelines and suggests using general-purpose software, exploring public-domain programs, investing in commercially available open-ended packages, and encouraging corporations to share their training software.
