Explores the use of visualization to enhance the information retrieval process, particularly in bibliographic retrieval systems. Topics discussed include document retrieval systems; human visualization; the VIBE (VIsualization by Example) system, a prototype system for visualizing a collection of documents; and differences between VIBE and more…

Describes ECAL (extended computer-assisted learning) which was designed to incorporate artificial intelligence ideas to extend traditional CAL tools. Intelligent tutoring systems are discussed; authoring tasks in CAL and intelligent computer-assisted instruction (ICAI) are described; and the general architecture of the system is explained. (8…

Reports on a pilot study in which a proposed design model was developed to characterize intergroup communication among designers, developers, and users. Design roles, themes, and networks based on two histories of design situations are described for several design phases; and future work is suggested. (24 references) (LRW)

Reviews entrepreneurial librarian leadership in the past and describes entrepreneurial opportunities in the foreseeable future involving the transfer from bibliographically based librarianship to user-based systems. A model of a user-oriented library information system is described, including users, libraries, publishers, and authors; and…

Reviews the evolution of instructional systems design and computer-based learning environments, focusing on the effects of technological advances. Classification of learning environments is discussed in the context of the dimensions of scope (macrolevel or microlevel), user activity (generative or mathemagenic), educational activity (goal-directed…

Describes how the structure of hypermedia systems can be represented by a simple matrix which is the basis for applying standard techniques of network analysis, and demonstrates the potential influence of these techniques on learning processes or outcomes. Also discusses theoretical and practical implications for future hypermedia research. (AEF)

Highlights some theoretical aspects of an alternative architecture for intelligent tutoring systems, introduces a prototype research tool in the domain of workcell scheduling, and suggests future theoretical and implementational work. Topics discussed include the roles of the user as domain expert and learner and the representation of domain…

Description of the development of the Information Exchange Facility, a prototype microcomputer-based personal bibliographic facility, covers software selection, user selection, overview of the system, and evaluation. The plan for an integrated system, BIBLIO, and the future role of libraries are discussed. (eight references) (MES)

Describes a Macintosh computer-based Instructional Development Model (IDioM) that provides a platform upon which an expert system for course development can be constructed. Goals of IDioM are explained, including instructional design and facilitating the development of interactive training courses; the use of HyperCard is discussed; and future…

Discusses differences between conventional books and electronic books, examines human-computer interface design issues, presents a development model for a hypermedia electronic book system, and describes the development of an electronic ABC book on CD-ROM for early learners. Future directions are also discussed. (24 references) (LRW)

Developed for the freshman writing program at University of Southern California (USC), Project Jefferson has two goals: to develop a model of computer-based instruction that includes the use of research tools and an interface that can be used with courseware in other disciplines; and to develop a researcher's notebook that permits easy access to…

Describes a modelling language for representing teaching strategies, based in the context of the COCA intelligent tutoring system. Examines work on meta-reasoning in knowledge-based systems and describes COCA's architecture, giving details of the language used for representing teaching knowledge. Discusses implications for future work. (AEF)

Discussion of text files and textual analysis in humanities research focuses on the results of two surveys of Research Libraries Group (RLG) academic libraries which was conducted to identify the systems used to support text files. Description of a system at the University of Michigan includes examples of screen formats, and seven sidebars…

Describes multimedia, computer-based interactive learning systems that support various forms of individualized study. Highlights include design models; user interfaces; design guidelines; media utilization paradigms, including hypermedia and learner-controlled models; metaphors and myths; authoring tools; optical media; workstations; four case…
