Factors which have previously provided the basis for decisions as to the use of CRT (cathode ray tube) of teletype terminals in computer-assisted instruction (CAI) may be decreasing in importance. Specifically, differential cost factors and teleprocessing capability may no longer provide a basis for differentiating between CRTs and teletypes. In…

An experiment was performed in a two semester introductory college physics course for non-science majors. The goal of the experiment was to determine the extent to which computer-assisted instruction (CAI) and knowledge of group dynamics can overcome the serious instructional problems of large introductory lecture courses. Students were divided…

This paper discusses media comparison studies and reasons that research of this nature is pursued, especially in the area of computer-based interactive video (CBIV). Three scenarios are presented to demonstrate instances in which the knowledge of the relative effectiveness of CBIV is important and useful: (1) the case of the administrator who…

Reports results of a study of the relative effectiveness of two library orientation/instruction methods--computer-assisted instruction (CAI) and a traditional library tour. Test scores and cost data for the two approaches are compared, and three CAI cost models are described. A significant cost advantage for offering CAI orientation/instruction is…

This review considers two major areas--research on educational media and research on school media centers (learning resource centers). Research reviewed in this report is limited to studies carried out in public school settings or that deal with issues of concern in public education. An introduction discusses the changing definition of…

Documents the design, development, and evaluation of a computer-managed spelling system for use with microcomputers in elementary schools. A comparison of this new technology with more conventional instruction, which indicated its greater effectiveness and economy, is also described, and implications for the future of computers in education are…

Claims that computers and other high technology can replace teachers and staff, thereby reducing educational costs, are unwarranted for several reasons. First, most cost analyses focus on hardware costs, which are not the major factor directing the cost of computer assisted instruction (CAI). Second, technology is more likely to change the skill…

Designed to develop procedures and acquire information to help decision-makers establish policies for the use of microcomputers for computer-assisted instruction (CAI), this study involved the following steps: (1) a school-based research project was conducted to determine the costs and effects of microcomputer-assisted instruction; (2) an…

This report documents an experiment to determine the training effectiveness of a microcomputer-based avionics system trainer as a cost-effective alternative to training in the actual aircraft. Participants--26 operationally qualified C-141 pilots with no prior knowledge of the Fuel Saving Advisory System (FSAS), a computerized fuel management…

Discussion of the cost effectiveness of distance education highlights an investigation that explored both the cost and the instructional effectiveness of using computer-mediated communication (CMC) for two courses in the U.S. Army Reserve Component. Student performance is compared and evaluated for CMC versus traditional resident courses. (24…

The costs, effects, and utility of mathematics instruction supplemented by microcomputer presentations were compared with those of traditional classroom approaches for grades 3 and 5. The study was completed at a single school in a rural area of Saskatchewan, Canada, where two classrooms at each grade level were used in a pretest-posttest design.…

This study was initiated to design, develop, implement, and evaluate a videodisc-based simulator system, the Interactive Graphics Simulator (IGS) for 6883 Converter Flight Control Test Station training at Lowry Air Force Base, Colorado. The simulator provided a means for performing task analysis online, developing simulations from the task…

This study was performed in response to the 1989 Department of Defense Appropriations Bill, which directed the Department of Defense to conduct a study on the use of interactive videodisk technology in education and training as it pertains to effectiveness, cost effectiveness, time on task, retention, and overall applicability to current and…

The COMPS course is a basic introductory computer course taken by first year Computer Systems students. Eighteen students took the course with Computer Assisted Instruction (CAI), while the rest of the students took the course in the conventional classroom setting. Although there was no difference between the two groups' mean group performance…

This paper focuses on the common features of Guided Discovery Architecture (GDA) online programs. It is also about developing a descriptive cost-benefit analysis of online program of GDA. It discusses how the features of GDA instruction differ from those of conventional distance education (DE) courses in terms of not only cost categories…
