CATO is a new user interface, written in Java and developed by the author as a response to the significant difficulties faced by students who only sporadically use computer algebra systems (CAS). The usage of CAS in mathematical lectures should be an integral part of mathematical instruction. However, difficulties arise for those students who have…

The purpose of this study was to explore critical thinking skills in peer feedback for Business English writing in order to facilitate the quality of peer feedback and quality of Business English writing. "Critical peer feedback" was conceptualized with the integration of "critical thinking" and "peer feedback" in…

Most educational software lacks either sophisticated computer assisted instruction (CAI) facilities or modern hypermedia functionality. Combining these two aspects not only increases interactivity between computer and learning persons by means of new functions such as moving dragbuttons across the screen and giving multimedia feedback, but also…

Previous work assessing the effectiveness of computers in education has gone no further than acknowledging a network of interconnected variables (comprising a system) which contribute to computer impact and describing its component parts. An impact systems model developed by Glasman and Bibiaminov (1981) has been adapted to facilitate measurement…

The need for traps, a program routine which checks the validity of the user's response to the computer's request for input, in Computer Assisted Learning Packages, is discussed. Several example traps are described. (MK)

A translating-computer-interface approach to providing a common, or virtual-system, mode of access to a network of heterogeneous online bibliographic retrieval systems has been investigated. Enhanced access to such systems by end users has been demonstrated through test usage of an experimental interface. A table-driven, rule-based message…

Discusses and compares advantages and disadvantages of large and small computer-based instructional systems. Predicted and actual costs in two systems--PLATO, which uses a mainframe system, and VITAL, a microcomputer-based system--are analyzed, and cost comparisons are made based on class size. (LRW)

Recommends an approach to computer-assisted language learning and development activities that addresses the total instructional system, including non-technological components. Eight procedural steps, based on an input-process-output model, are described for developing, refining, and evaluating the efficiency and effectiveness of CALL teaching…

Flight simulators, computer-based instruction (including both computer-assisted and computer-managed instruction), and maintenance training simulators are as effective, when used for training, as aircraft, conventional classroom instruction, and actual equipment, respectively. Data from about 100 studies are reported to support this finding. These…

The purpose of this investigation was to develop a computer-based model for maximizing both the feedback of an administrative "in-basket" simulation exercise and the analysis of the results. The development of the model consisted of three phases: (1) instrumentation, (2) computer interaction, and (3) experimentation and refinement. The…

The PLATO IV computer-based instructional system consists of a large scale centrally located CDC 6400 computer and a large number of remote student terminals. This is a brief and general description of the proposed input/output hardware necessary to interface the student terminals with the computer's central processing unit (CPU) using available…

This paper presents the concepts of a computer-directed system to improve human performance in structured learning situations. Attention is focused on finite-state systems in order to provide a systematic method for constructing training systems and to assist in analysis of problem solving and curriculum planning. The finite-state approach allows…

Misunderstandings on the part of the researcher as to the computer's capability, coupled with the inability of the computer system to function efficiently, has often handicapped the research activities in computer assisted instruction (CAI). A new data system is being developed to resolve these problems. A Delete/Sort program has been designed to…

AN INSTRUCTIONAL MANAGEMENT SYSTEM IS DESCRIBED AS AN INTERIM APPROACH TOWARD WIDESPREAD ADOPTION OF COMPUTER-BASED INSTRUCTION. AN EXPERIMENTAL PROTOTYPE OF THE INSTRUCTIONAL MANAGEMENT SYSTEM IS BEING DEVELOPED BY SYSTEMS DEVELOPMENT CORPORATION UNDER A CONTRACT FROM THE SOUTHWEST REGIONAL LABORATORY FOR EDUCATIONAL RESEARCH AND DEVELOPMENT. IT…

Four computer programs to aid students in understanding inventory systems, constructing mathematical inventory models, and developing optimal decision rules are presented. The program series allows a user to set input levels, simulates the behavior of major variables in inventory systems, and provides performance measures as output. Inventory…
