Discusses the design and implementation of lexicons in computer-assisted language learning (CALL). Topics addressed include the dictionary's role in the learner's acquisition of vocabulary as opposed to its use as a reference tool; mental lexicons; electronic dictionaries; morphological processing; context sensitivity; layering information; and…

Reports on studies that analyze the impact of microcomputers in schools on student achievement as compared to more traditional methods, and explores research that relates student achievement to software design, learner characteristics, and instructional decisions on technology implementation.

This article examines the concept of interactivity and discusses human-to-human interactivity versus computer-to-human interaction in education. Levels of communicative interdependence are explained, variables that are important ingredients of interactivity are discussed, learner control is discussed, and two interactive instructional systems are…

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)

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…

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…

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…

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)

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…

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…

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…
