Discusses a research program at Utah State University that is developing an advanced instructional design theory to help produce an integrated computer-based system. Highlights include a theoretical base that organizes knowledge about instructional design, a methodology for representing domain knowledge; miniexpert systems; instructional…

Replies to Watts's article concerning computer-aided careers guidance systems (1993). Reviews the U.K. experience of computer-aided guidance systems, comments on the development of PROSPECT which Watts uses as a case study, identifies strengths and weaknesses of existing research, and sets out a research agenda. (JPS)

Discussion of performance support focuses on Canada's Bell-Northern Research's views of embedded performance support systems. The establishment of a corporate center of excellence for performance support system (PSS) development is explained; a pilot project is described; and a business case showing the benefits of implementing a PSS is presented.…

The review examines six personal computer-based optical character recognition (OCR) systems designed for use by blind and visually impaired people. Considered are OCR components and terms, documentation, scanning and reading, command structure, conversion, unique features, accuracy of recognition, scanning time, speed, and cost. (DB)

Discusses document processing software packages and describes the TEX system, a document compiler intended to produce high quality typesetting. It is noted that the X-window system provides a windowing environment that makes the system faster, more efficient, and more user friendly, and its use in connection with the TEX system is explained. (four…

Discussed is one facet of a broad range of research activities that fall under the rubric of a study commonly called virtual reality. Projects developed by IBM and other academic and industrial laboratories are described. The limitations of virtual reality are presented. (KR)

Describes a study conducted at the University of South Carolina that examined the frequency of occurrence of several types of errors in a sample of natural language queries submitted by users requesting online searches in information retrieval systems. Implications for system design are suggested, including parsing systems. (28 references) (LRW)

Discusses software sharing on computer networks and the need for proper bandwidth; and describes the technology behind FidoNet, a computer network made up of electronic bulletin boards. Network features highlighted include front-end mailers, Zone Mail Hour, Nodelist, NetMail, EchoMail, computer conferences, tosser and scanner programs, and host…

Introduces a special issue on research on hypertext systems and information retrieval. Systems design aspects, including navigation models, link weighting, multiple representation techniques, automatic authoring, user modelling, varying levels of abstraction, and evaluation techniques are addressed. (EA)

Discusses instructional design models and examines rapid prototyping, a model that combines computer design strategies, constructivist learning theory, and cognitive psychology. Highlights include limitations of linear models; instructional problems appropriate and those not appropriate for rapid prototyping; and rapid prototyping as a paradigm…

The spectacular increase in Internet-based applications during the past decade has had a significant impact on the education delivery paradigms. The user interactivity aspect of the Internet has provided new opportunities to instructors to incorporate its use in developing new learning systems. The use of the Internet in carrying out live…

Despite a growing development of virtual laboratories which use the advantages of multimedia and Internet for distance education, learning by means of such tutorial tools would be more effective if they were specifically tailored to each student needs. The virtual teaching process would be well adapted if an artificial tutor can identify the…

This report presents the results of a research and development effort for SpeechRater? Version 1.0 (v1.0), an automated scoring system for the spontaneous speech of English language learners used operationally in the Test of English as a Foreign Language™ (TOEFL®) Practice Online assessment (TPO). The report includes a summary of the validity…

Computer-supported discursive learning (CSDL) systems for the support of asynchronous discursive learning need to fulfill specific socio-technical conditions. To understand these conditions, we employed design experiments combining aspects of communication theory, empirical findings, and continuous improvement of the investigated prototypes. Our…

This paper proposes a learning based method that can automatically determine how likely a student is to give a correct answer to a problem in an intelligent tutoring system. Only log files that record students' actions with the system are used to train the model, therefore the modeling process doesn't require expert knowledge for identifying…
