This report describes a computer managed instruction (CMI) system operated by the Navy which involves approximately 9,000 students a day in ten technical training schools, and the research and development effort that has taken place to ensure the most cost-effective and productive technical training system. Major system problems were identified and suitable research proposals were developed through a four-phase effort: (1) identification of system problems through observation, questionnaires, and interviews with CMI management, instruction staff, and student personnel; (2) review of other CMI systems; (3) development of candidate research and development proposals to support the major problem areas; and (4) setting R&D priorities. Initial research efforts on the six proposals given the highest priority status are described, including the effects of incentive charts on rate of progress through a CMI course, instructor role in a CMI environment, computer generated reports for the management of student learning, development and incorporation of automated performance tests into the CMI system, development of alternate test strategies to improve mastery and retention in selected CMI courses, and development of computer software to aid data summarization for research and management analysis.
