Discussion of research on computer-aided instruction (CAI) focuses on a set of questions and hypotheses that form the basis for research on the effectiveness of CAI. Four factors are highlighted: (1) the medium (including interactive videodisc); (2) the environment; (3) student characteristics; and (4) topic of instruction. (38 references) (LRW)

Discussion of the human-technology interface highlights computer technology in relation to the management of open and distance learning for adults. Examples from higher education and continuing education in Australia are presented, and design considerations for technology-based delivery systems for adults are suggested. (13 references) (LRW)

This study investigated the usefulness of end user systems to library and information science students. Seventeen volunteers were offered free searching on BRS/After Dark and DIALOG's Knowledge Index. The search itself, postsearch questionnaire, and completed research papers were analyzed for databases used, cost and time online, and precision.…

Highlights the changes that have occurred from 1987-93 in database access systems. Topics addressed include types of databases, including CD-ROMs; enduser interface; database selection; database access management, including library instruction and use of primary literature; economic issues; database users; the search process; and improving…

Describes virtual personal computing, a computer-based educational infrastructure for all students from kindergarten through college, as a step toward meeting national educational goals. New technologies that make this concept possible are described, including the Asymmetric Digital Subscriber Line (ADSL); and the theoretical basis of the virtual…

Describes approaches to developing software automating instructional design (ID), including comparison of information management and expert system approaches. Topics addressed include alternative ID automation systems; ID variables; authoring assistance software; the nature of ID expertise; user-system communication; system evaluation; and user…

Discusses software engineering and suggests necessary elements in a software engineering curriculum. Topics addressed include the importance of theory, project-oriented education, prototyping, exploratory programing, human-computer communication, thought models, distributed systems, parallel processing, documentation, testing and quality…

This paper considers the technological aspects of learning environment analysis in the instructional development process. Characteristics of a technology-based learning environment are discussed, and old and new models of technology and learning are examined. The connection between technology and cognition is addressed, and the importance of…

This review of the research literature on the interaction between humans and computers discusses how man machine systems can be utilized effectively in the learning-teaching process, especially in secondary education. Beginning with a definition of man machine systems and comments on the poor quality of much of the computer-based learning material…

Defines artificial intelligence and reviews current research in natural language processing, expert systems, and robotics and sensory systems. Discussion covers current commercial applications of artificial intelligence and projections of uses and limitations in library technical and public services, e.g., in cataloging and online information and…

Discusses information gathered in past few years related to health effects of video display terminals (VDTs) with particular emphasis given to issues raised by VDT users. Topics covered include radiation emissions, health concerns, radiation surveys, occupational radiation exposure standards, and long-term risks. (17 references) (EJS)

This review of the transition from library card catalogs to online public access catalogs (OPAC) (1981-1982) discusses methods employed by online catalog use studies (self-administered questionnaires, OPAC transaction logs, focused-group interviews, feature analysis, online search and retrieval experiments) and new directions for OPAC research…

Presents a general framework for human factors considerations in training and illustrates the relationship between human factors and computer-based training (CBT) research by descriptions of studies dealing with six major aspects of the CBT interface: training administration, management, instructional design and development, testing and…

The importance of alternative access to computers for persons with developmental disabilities and the ways in which speech recognition technology has been used to reach this goal are discussed. Illustrative studies of the use of speech recognition by persons with disabilities are reviewed, and implications for the effective application of this…

Examines how users interact with text to devise a more effective information retrieval interface. Research in cognitive psychology and information science that relates to the use of metaphors and document categorization is reviewed, and an example of text organization and retrieval by historians is presented.
