Current activities of the Computer Curriculum Corporation and university level computer-assisted instruction at Stanford University are highlighted. Stanford's programs in logic, axiomatic set theory, computer-generated speech, and informal mathematical proofs are described and predictions are made for future developments in CAI. (RAO)

Considers complaints about the usability in the human-computer interaction aspect of information retrieval and discusses information visualization, the Online Library of Information Visualization Environments, hyperbolic information structure, subject searching, real-world applications, relational databases and hyperbolic trees, and the future of…

Discusses the distinction between cognitive effects with computers, whereby an individual's performance is redefined and upgraded during intellectual partnership with the computer, and effects of computers, whereby such partnership leaves durable and generalizable cognitive residues. Suggests two mechanisms for affecting cognition: skill…

Emphasizes the need for business or technical writing teachers to consider the machines used in the workplace when planning materials and procedures for courses. Recommends gaining familiarity with machines, choosing which technology to teach, and implementing the use of computers and other business machines in the classroom. (KEH)

Provides annotated citations to articles, research reports, resources guides, and a newsletter about the use of computer networks for real-time written interaction in writing classrooms. Notes that these annotations offer a broad and varied introduction to computer networking in the writing classroom. (KEH)

Traces the early history of the electronic digital computer and the viewpoints held concerning the computer from its inception to its present status. Highlights three key words ("mimesis,""topic," and "decorum") to develop the rhetoricality of the personal computer as a communications device. (KEH)

Compares the strengths and weaknesses of four authoring systems that can be used for courseware development: (1) Quest; (2) PCD3; (3) IconAuthor; and (4) Course of Action. Evaluation procedures used to assess their power, ease of use, and productivity aids are explained; menu and icon structures are described; and interactive design implications…

Proposes a conceptual reference architecture for information retrieval systems and discusses functional capabilities of a hypertext environment, based on the proposed architecture, for interaction with large textual databases. Functions of the prototype system HYPERLINE are described, and an example of a user session is provided. (17 references)…

Provides an overview of Circuit II, an interactive system that provides users with a graphical representation of an electronic circuit within which questions may be posed and manipulated, and discusses how mouse selections have analogous roles to certain natural language features, such as anaphora, deixis, and ellipsis. (13 references) (EA)

Presents a theoretical framework for navigation in information retrieval systems and describes a prototype retrieval system that was developed to investigate navigation. The use of a visual interface in a spatial representation scheme is described, and results of a user-based evaluation of the system are reported. User questionnaires are appended.…

Major changes affecting Swiss graphic arts are photocomposition, replacement of letterpress with offset printing, scanners, and microcomputers and laser printers for desktop publishing. Effects on workers include monotony, alienation, and apprehension. Sex discrimination continues in the industry. (SK)

Discusses the importance of skillful visual design of computer screens and provides guidelines for screen design in the areas of information resolution, interaction of design elements, color, and typography and icons. (MES)

Discusses conceptual differences between electronic and printed texts using a literature review that categorizes studies as convergent (i.e., electronic text as conceptually the same as printed text) or divergent (i.e., electronic text as conceptually different.) Four differences based on theoretical positions and findings from divergent studies…

Reports preliminary results of a study that investigated the nature of feedback during 40 uses of user-intermediary-information retrieval system interaction through the use of microanalysis. Types of feedback based on human judgments include magnitude feedback, relevance feedback, term relevance feedback, tactical review feedback, and terminology…

Discussion of management decision making and the support needed to manage successfully highlights a Decision Technology System (DTS) that integrates other information systems. Topics discussed include computer information systems (CISs); knowledge gateways; the decision-making process; decision support systems (DSS); expert systems; and facility…
