This is the fourth and final installment in a series of articles presenting a new outlook on the methods of instructional design. These articles examine the nature of the process of instructional design and are meant to stimulate discussion about the roles of designers in the fields of instructional design, the learning sciences, and interaction…

An approach to the design of computer systems and applications in which scenarios of human-system interaction are a central working design representation are described and illustrated by examples from the design of a multimedia information system. (Contains 21 references.) (KRN)

Describes human-computer interface needs for empowering environments in computer usage in which the machine handles the routine mechanics of problem solving while the user concentrates on its higher order meanings. A closed-loop model of interaction is described, interface as illusion is discussed, and metaphors for human-computer interaction are…

This paper discusses the complexity of explanation activity in human-human goal-directed dialogue and suggests that this complexity ought to be taken into account in the design of explanation in human-computer interaction. A general model of clarity in human-computer systems is proposed, incorporating explanation as one component. On the basis of…

Examines various ways of dividing the labor of an information search between the person and the system. Different configurations of two dimensions--degree of system involvement in searching and types of search activity carried out by the person or system--are discussed. Recommendations for further research and development are offered. (49…

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

This paper describes and critically analyzes several perspectives on interaction and computer technology, examines dimensions of interactions, and presents a framework for the design of interaction strategies. Traditional perspectives on interaction discussed are the operational and the functional. The operational perspective is described in terms…

Describes the development of a model for future national and international digital libraries. Four aspects of the model are presented: (1) nine principles underlying constructing electronic archives; (2) a study of potential user needs; (3) the design and evaluation of the user interface; and (4) objects and document type definition development.…

This document presents hypotheses about how much understanding a user needs to perform skillfully using a computer or a computer program. A framework for characterizing user understanding is presented which includes three criteria for evaluating the representation generated during problem solving: (1) internal coherence--whether the components of…

Discussion of intelligent tutoring systems highlights various instructional models which emphasize experiential interactions. Topics discussed include computer assisted instruction; instructional strategies; the TICCIT system; branching; the Socratic method; definitions of tutoring and instruction; students' interactions with the computer; advisor…

Discusses theory of mental models--i.e., representations of relationships within a system which enable the user to produce mental simulations of the system's actions and develop ways of dealing with it--and its implications for user training, interface design, and overall systems design. (EJS)

Presents evidence to show that the body plays a continuing and fundamental part in the process of thinking and the development of the knowledge used to think. Topics discussed include knowledge structures and representations; artificial intelligence; feeling; learning processes; models of knowledge; information retrieval; and implications for…

Addressing the need for a framework to distinguish the conditions under which different types of educational computing environments are productive, this paper proposes a cognitively based Contextual Analysis Framework consisting of two primary elements: (1) conceptual characteristics of the knowledge domain being learned, including the complexity…

This paper describes a Prolog execution model which serves as the uniform basis of textbook material, video-based teaching material, and an advanced graphical user interface for Prolog programmers. The model, based upon an augmented AND/OR tree representation of Prolog programs, uses an enriched "status box" in place of the traditional…

This report incorporates a literature review, a workshop paper, and discussion by workshop participants on the current status of research on what the users of computer systems know, and how these different forms of knowledge fit together in learning and performance. It is noted that such research is important to the problem of designing systems…
