Local area networks (LANs) are systems of computers and peripherals connected together for the purposes of electronic mail and the convenience of sharing information and expensive resources. In planning the design of such a system, the components to consider are hardware, software, transmission media, topology, operating systems, and protocols.…

Discusses the design of interfaces for online systems and suggests requirements that must be met to offer maximum aid to inexperienced users. Highlights include the online search process, user data, query processing, database descriptors, semantic links, multilingual processing, search strategies, and distributed systems. A 20-page bibliography…

Describes a study of undergraduates that compared three strategies for indicating links in a hypermedia system to determine their effect on learner navigation and learner perceptions of ease of use. Highlights include three linking display types; the density of links; elaboration types; time intervals; and implications for hypermedia system…

Describes efforts by the Motorola Training and Education Center (MTEC) to develop and implement a model for applying the concepts of quality/continuous improvement to the design of courseware. MTEC's role as change agent is discussed; the use of an instructional systems design model is explained; and problems are identified. (LRW)

An implementation of the Gauss-Newton algorithm for the analysis of covariance structure that is specifically adapted for high-level computer languages is reviewed. This simple method for estimating structural equation models is useful for a variety of standard models, as is illustrated. (SLD)

Open systems are computer systems designed to meet vendor-neutral international standards. Significant characteristics of open systems are portability (software will run on dozens of hardware programs) and interoperability (computers of different brands can be connected and share resources). Discusses options available to switch to an open system.…

Reports on the use of computer-assisted learning and teaching in 16 Australian schools of library and information studies. Topics addressed include courses and subjects using computer-assisted learning and teaching, the reasons for and advantages of this use, types of software use, facilities and equipment, and limitations and future plans. (15…

Describes a variety of computer software programs and student activities utilizing the computer to help teach secondary social studies. Suggests using word processors, painting programs, and computer simulations for history and government courses. Concludes that successful use of computers in social studies instruction depends on the design of…

A guide to development of effective computer-assisted instruction outlines four essential phases (planning, design, execution, and distribution), with specific activities to occur in each phase. In addition, frequent internal review is seen as critical to effective application. (MSE)

Describes a study of high school students that investigated the impact of embedding an instructional map into hypermedia courseware on student achievement. Treatment of experimental and control groups is described, results of pretests and posttests are compared, and implications for software designers and teachers are suggested. (Contains 23…

Discusses reasons for the slower acceptance of educational technology in the humanities. Highlights include teacher training; support staff skills; software development; lack of equity in funding for hardware and software; technology diffusion; and a description of the Concerns-Based Adoption Model, a comprehensive model of change in education.…

Investigates whether students in business communication courses perceive that their writing skills are enhanced with the use of a computer-assisted instruction program (Writer's Workbench). Finds that, although these students did not perceive significant improvement in writing, they perceived significant improvement in their oral communication…

Through case studies, this article examines how technology can be used as part of intervention strategies with language handicapped children. It discusses theoretical considerations; stimuli, responses, and reinforcements; staff roles; individualization; and software. The need for increased accessibility to computers by speech/language clinicians…

A program using interactive software based on repertory grid techniques was used to monitor progress of first-year nursing students at the University of London, to learn student reactions to courses and illuminate individual difficulties and concerns. The approach is found to provide useful information to course providers and evaluators.…

Discusses new hardware and software developments for microcomputers and considers strategies for future library microcomputing. Topics discussed include developments with Macintosh computers; the importance of local area networks (LANs); upgrading options for hardware; operating system upgrades; dynamic data exchange (DDE); microcomputer…
