The third of three volumes of papers presented at the 1979 ADCIS convention, this collection includes 30 papers presented to special interest groups--implementation, minicomputer users, National Consortium for Computer Based Music Instruction, and PLATO users. Papers presented to the implementation interest group were concerned with faculty reactions to CAI tutorials, review lessons in English compositions, thematic information text revisions, self-paced instruction, problem solving with automatic mediation, linear programmed instruction compared with CAI, the computer in educational institutions, CMI and student achievement, software development, and the role of the computer programmer. Minicomputer projects described focused on self-paced learning, a shared CAI control program, as a classroom teaching tool, the current state of the field, the development of PILOT, and personal computers. Music educators heard papers on courseware development for microcomputers, CAI in music theory, evaluation of competency based aural training, and ear training for non-music majors. Reports on PLATO included the teaching of sex education, process operator training, foundation visual design, adult basic skills, and optical letterspacing, as well as on precision motion analysis in biomechanics, microprocessor courseware delivery, and the development of a user's guide. Some papers include flow charts, diagrams, data tables, models, and/or bibliographies. (RAO)
