Discussion of search strategy in information retrieval by end users focuses on the role played by strategic reasoning and design principles for user interfaces. Highlights include strategic help based on collaborative coaching; a conceptual model for strategic help; and a prototype knowledge-based system named FIRE. (Author/LRW)

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)

Describes Aran, a knowledge-based system designed to help users deal with problems related to Unix operation. Highlights include adaptation to the individual user; user modeling knowledge; stereotypes; content of the individual user model; instantiation, acquisition, and maintenance of the individual model; dynamic acquisition of objective and…

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…

Presents a World Wide Web page model that reacts to pre-defined events and performs actions like "prefetching" automatically. Discusses the active index, conceptual page model; design of the client system, status of the current implementation, prefetching algorithm, an experiment of the algorithm, experimental results of the active index…

Describes features of a Training Innovations computer-based training system in which guided paths can be dynamically adapted to learning style or capacity, skill or knowledge level, and cultural background. It also allows program authors to work with scripted graphics and desktop publishing tagging without extensive expertise, and even exhibits…

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…

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)

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.…
