This guide contains a compilation of suggestions and guidelines to assist secondary-level teachers in planning to make the most effective use of computer-assisted instruction (CAI) through careful courseware evaluation. It is part of BASICS, a set of integrated materials developed to assist teachers, administrators, and counselors in bridging vocational and academic skills. An introduction defines CAI and relates it to the joint vocational-academic approach. The next three sections are structured around a checklist that deals with three major tasks: plan for effective use of the computer, establish guidelines for developing or evaluating software, and evaluate courseware. Three steps in planning for effective use of the computer are discussed: identify the benefits of CAI, identify appropriate tasks for CAI, and identify strategies for CAI. Establishing guidelines involves the following steps: identify the learning objectives and tasks, determine teaching effectiveness, evaluate appropriate use of computer capabilities, identify management possibilities, and evaluate documentation. The section on courseware evaluation provides information about microcomputer courseware evaluation sources and the Microcomputer Courseware Evaluation Form and Guide. (YLB)
