This is the third in a series of articles discussing models that can be used to help students visualize the interaction of computer hardware and software. It focuses on a demonstration of how the computer works when the LOGO programing language has been added to memory. (LRW)

Discussion of the use of computers in math instruction highlights two possibilities suggested in response to an earlier journal column: (1) a program written in BASIC for producing spirolaterals, and (2) the use of LOGO list processing to solve matrix problems for exploring geometric transformations. (LRW)

Rebuts arguments raised against computer assisted instruction (CAI). The potential problems of CAI relating to health, negative pedagogical effects, theoretical limitations, costs, and teachers' attitudes are discussed. Those who incorporate CAI have a responsibility to ensure its best possible use and limit its negative effects. (CB)

Discusses three trends in remedial instruction that merit the attention of clinicians and teachers including: individualized instruction based on individualized diagnosis, effective teacher questioning during prereading activities to establish purpose, and interactive computer assisted instruction which provides immediate feedback. (RS)

The computer software TOPIC is designed primarily for the acquisition and practice of topical vocabulary in context. It bridges the gap between ready-made "learnware" and authoring packages by meeting teacher and learner requirements. Sample exercises are provided. (Author/LB)

In this paper, experiments with equal-length and different-length coupled pendulums were carried out measuring the frequency of energy exchange between them using microcomputer-based technology. The experiment described in this paper would be most appropriate for an introductory mechanics laboratory course. (15 references) (LZ)

Presents a comprehensive synthesis of research on learning strategies, focusing on the practical use of these strategies in CAI (computer-assisted instruction) design; identifies 13 of the most researched learning strategies and suggests ways to incorporate them into CAI design; and discusses future research topics. (Contains 63 references.) (LRW)

A typology of authoring programs in computer-assisted language learning (CALL) with different features (reconstruction, rearrangement, matching, transformation, multiple choice, vocabulary data bank, simulation) is presented. Examples of screen presentation methods and a catalog of teaching/learning software requirements are included. (Contains 12…

Notes that, whereas technology in the classroom has served primarily as a means of making learning more efficient without affecting broader aims, that role is changing as a new pedagogy emerges, one that alters both the means and ends of education. Outlines four general themes that distinguish the emergent pedagogy and the role of technology in…

Describes the use of barcodes to link laser discs with books in school libraries. Highlights include use of a barcode reader as a remote control device as well as a scanner, guidelines for making laser disc books, and a sidebar that explains how to make barcodes and describes software. (LRW)

Explains the "Point and Query" (P&Q) Interface which trains students to develop good questioning strategies, decrease search time and increase retention and recall. Navigation and knowledge organization in the P&Q interface are explained; and two experiments demonstrating P&Q use are presented. (Contains 16 references.) (SLW)

Discusses how to design effective user interfaces for computer-based training (CBT) programs. Four types of interfaces are described: presentation, including consistency; conversation, including feedback and flexibility; navigation; and explanation, including online help. A job aid for evaluating CBT interfaces is included. (Contains 13…

Members of 24 work groups (n=186) were randomly assigned to facilitated team building with computers; facilitated team building without computers; or meetings without facilitators or computers. Both facilitated groups rated group process higher, but the positive effects did not last over time. (SK)

This survey elicited experts' perceptions of factors affecting development and use of interactive technologies. Responses from 196 respondents were categorized as hardware/technology, software/programs, acceptance/adoption, accessibility/ease of use, and instruction/learning/communication issues. Based on this categorization, a model of…

Describes fiber optic cables and coaxial cables and considers when each would be appropriate for educational technology. Single mode versus multimode fiber optics are explained, advantages and disadvantages of each type of cable are discussed, and guidelines for choosing fiber optic cables and coaxial cables are offered.
