Van Aalst, J. W.; And Others – Computers & Education, 1995
An interactive multimedia tutorial system that focuses on the "why" aspect of user interface design is described. The system contains a design exercise, three experts for guidance, and a user group that comments on the usability of the design. Testing results indicate that learners consider more possible solutions to design issues. (Author/AEF)

Barnard, Philip J.; May, Jon – Human-Computer Interaction, 1999
Interacting cognitive subsystems (ICS) is proposed as a unified cognitive theory that can be used as the basis for representations in human-computer interaction, and two approaches based on the theory are described: one entails the description of cognitive task models, and the other entails the production of less complete diagrammatic notations.…

Koneman, Philip A.; Jonassen, David H. – 1994
Hypertext is well-suited for educational applications where open learning and knowledge exploration is desired. In such applications, principles of good hypertext interface design should be employed to avoid navigational problems so as to maximize learning. Interface design, however, may also directly enhance acquisition of a particular knowledge…

Hodges, Julia E.; And Others – RE:view, 1995
This study evaluated interfaces (menu-driven, natural language, or hybrid) for using the Computer Access Technology-Knowledge Based Expert System (CAT-KBES), which assists in the selection of appropriate computer access technology for clients with severe visual disabilities. Users (n=19, including 12 with visual impairments) preferred the revised…

Gold, Steven C. – Simulation & Gaming, 1998
Discusses the design and use of intelligent tutoring systems (ITS) for computerized business simulations. Reviews the use of ITS as an instructional technology; presents a model for ITS-based business simulations; examines the user interface and link between the ITS and simulation; and recommends expert-consultant diagnostic testing, and…

Warren, James R.; And Others – Simulation & Gaming, 1997
Discusses how simulation technology for the analysis of information systems (IS) supports human decision making. Examines online help and knowledge-based support, graphics, and visual interactive simulation (VIS) and animation. Concludes that there are opportunities to improve the decision support role of simulation technology in IS with enhanced…

Du Plessis, Johan P.; And Others – Computers & Education, 1995
Proposes a model for intelligent computer-aided education systems that is based on cooperative learning, constructive problem-solving, object-oriented programming, interactive user interfaces, and expert system techniques. Future research is discussed, and a prototype for teaching mathematics to 10- to 12-year-old students is appended. (LRW)

Khoo, Christopher S. G.; Poo, Danny C. C.; Toh, Teck-Kang; Hong, Glenn – 1999
E-Referencer is an expert intermediary system for searching library online public access catalogs (OPACs) on the World Wide Web. It is implemented as a proxy server that mediates the interaction between the user and Boolean OPACs. It transforms a Boolean OPAC into a retrieval system with many of the search capabilities of Web search engines.…

Neerincx, Mark A.; de Greef, H. Paul – Human-Computer Interaction, 1998
This study of 40 undergraduates examined whether aiding as cognitive support (i.e., offering computer users knowledge they are missing) can supplement lack of knowledge and capacity under tasks with high mental loading, such as dealing with irregularities in process control. Users of a railway traffic control simulator dealt better and faster with…

Sebrechts, Marc M.; And Others – 1993
This report describes the development of a new tool for assessment research in graduate education. The tool, the Algebra Assessment System, is based on GIDE, a pre-existing program that diagnostically analyzes complex constructed responses to algebra word problems. The project had three goals. The first goal was to build a generically usable…
