When the Learning Sciences emerged in 1991, there was an ethos of studying learning in humans and machines in conjunction with one another. This ethos reflected three decades of prior work on the interdisciplinary study of learning; however, in the three decades since the emergence of the Learning Sciences, it seems to have largely disappeared. I…

A framework connecting concepts from user interface design with those from information studies is applied in a study that integrated a location-aware mobile application into two special education classes at different schools; this application had two support modes (one general and one location specific). The five-month study revealed several…

Since the designer of interactive materials must ensure that the learner is directed to the information that he will be expected to acquire, he must recognize the components of the delivery system employed and the process by which they interact to deliver the information. (Author/RAO)

Notecards is a computer environment designed to help people work with ideas by providing a set of tools for a variety of specific activities, which can range from sketching on the back of an envelope to formally representing knowledge. The basic framework of this hypermedia system is a semantic network of electronic notecards connected by…

Clinically oriented computer systems require compatibility with the information processing that typifies clinical work. This paper summarizes some of the research that can be applied to such processing and uses the summary to suggest likely errors. Emphasis is placed on decision support systems that integrate human and computer information…

The computer is seen as a powerful tool that offers great potential for administrators in tertiary institutions. The impact of the computer on processing data, database concept, computer communication, utilization of operations data for analytical reports, use of management science tools, and evolution in administrative data processing are…

Presents a list of recommended practices for designing computer-based instruction courseware based on principles derived from learning research. Research-based principles and the corresponding design practices are outlined for the areas of stimulus design, learner responses, feedback, and lesson control. (6 references) (CLB)

Summarizes the key research issues and developments in cognitive science, especially with respect to the similarities, differences, and interrelationships between human and machine information processing. Nine references are listed. (JL)

Intermedia, a hypermedia system developed at Brown University's Institute for Research (Rhode Island) in Information and Scholarship, is first described, and then used as a case study to explore a number of key issues that software designers must consider in the development of hypermedia document systems. A hypermedia document system is defined as…

Reviews developments in research on information storage and retrieval, question-answering and natural language interface online systems, and the processes of synthesis and interpretation in intelligent behavior. Problem formulation, information requests, and knowledge representation are discussed in relation to the design and use of retrieval…

Presents a four-stage hypothesis of information systems development based on computational capability, storage capability, communications capability, and effective voice input. Moore's Law and Mooers' Law are explained, the interface between the system and the user is discussed, and projections for the future are suggested. (21 references)…

Describes the formation of the supercomputer system which reaches from Seattle to South Florida. Explains the major obstacles of international protocols, billing, priority routing, and security. (RT)

Discusses impact of three selected command language facilities (positional or free text operations, crossfile searching, term frequency analysis--ZOOM) on the man-system interface in relation to operational online information retrieval (IR). A cognitive IR model, searchers' knowledge structures, and searching with different types of command…

Outlines the technological evolution and the use of computers and telecommunications in information transactions and data storage. (CWM)

Focuses on natural language processing (NLP) in information retrieval. Defines the seven levels at which people extract meaning from text/spoken language. Discusses the stages of information processing; how an information retrieval system works; advantages to adding full NLP to information retrieval systems; and common problems with information…
