Discusses features of online public access catalogs: (1) demonstration of relationships between records; (2) provision of entry vocabularies; (3) arrangement of multiple entries on the screen; (4) provision of access points; (5) display of single records; and (6) division of catalogs into separate files or indexes. User studies and other research…

Reports on a study of 203 title pages as the source of information for descriptive cataloging, and bibliographic data on title pages as written artifacts having their own visual characteristics. Frame structure representations at various levels of abstraction are suggested for a prototype title page, and expert systems for descriptive cataloging…

Considers three main components of self-directed learning: (1) topic knowledge; (2) procedural skills; and (3) self-monitoring. The role of computer-assisted instruction in autonomous learning is discussed, software that fosters independent problem solving is reviewed, and it is recommended that computers be incorporated in courses emphasizing…

Investigated the effects of developmental and nondevelopmental computer software on four- and five-year-old children's intelligence, creativity, and self-esteem. Also assessed the effect of supplementing developmental software with related activities. Children exposed to developmental software supplemented with activities had gains in more areas…

Hypertextual ways to think about evaluation are explored, and hypertext computer programs are discussed. Hypertext is useful as a way to search out and link related material. It can help maintain, manipulate, and analyze nonnumerical evaluation data. (SLD)

Effects of social facilitation and equilibriation were examined for 80 third and fourth graders working under interdependent, coactive, or individualized conditions to complete high and low complexity computer tasks. Results indicate that interdependent and coactive conditions are not detrimental to performance but do not enhance individualized…

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)
