Described are materials developed to add to existing complex-number units and how they have been used in second-year algebra and precalculus classes. Discussed is software developed, objectives, and classroom materials. Two worksheets are included. A computer program is provided. (CW)

The purpose of this paper is to show, by computer examples, that very different results can be obtained by rearranging selected conditionally convergent series. Computer programs allow the students to select the real number to which they wish the rearrangement to converge. Two computer programs are appended. (KR)

Deaf students in grades 6-8 issued a newspaper as a regular part of the English curriculum. The project involved making a trip to a newspaper publisher, setting aside a "newsroom" classroom area, selecting staff, brainstorming story ideas, learning to use the Newsroom computer program, writing, editing, and planning the layout.

This summary of the literature on document image processing from 1988-90 focuses on WORM (write once read many) technology and on rewritable (i.e., erasable) optical discs, and excludes CD-ROM. Highlights include vendors and products, standards, comparisons of storage media, software, legal issues, records management, indexing, and computer…

Describes Vitrine 2001, an innovative computer-based learning environment at the Quebec Centre for Research in Educational Computing. Highlights program responses to educational software deficiencies; teachers' limitations in providing appropriate pedagogical support; and the need for support materials to help children get the most out of their…

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)
