Discussion of teaching college level mathematics using computer algebra systems (CAS) focuses on a new microcomputer-based teaching/learning environment called Computer Algebra and Logo (CAL). Highlights include the teachers' role in the development of mathematics teaching and learning environments; methods and goals of implementation; and…

Describes the design and development of an image database for photographs in the Ulster Museum (Northern Ireland) that used parallelism from a transputer network. Topics addressed include image processing techniques; documentation needed for the photographs, including indexing, classifying, and cataloging; problems; hardware and software aspects;…

Describes the Mercury Electronic Library, a project at Carnegie Mellon University that involved development of software for an electronic library, implementation of the software by the university libraries, and stimulation of the market for electronic publishing. The library information system interface and databases and the computing system…

Discusses cultural diversity in human-computer interactions and in the design of online systems. Topics addressed include cognitive psychology; North American and European ethnocentricity; online systems and their organizational setting; models for organization culture; corporate culture; international systems and country-specific cultures; and…

Describes virtual personal computing, a computer-based educational infrastructure for all students from kindergarten through college, as a step toward meeting national educational goals. New technologies that make this concept possible are described, including the Asymmetric Digital Subscriber Line (ADSL); and the theoretical basis of the virtual…

Describes a study that investigated the effects of cognitive style (field dependent and field independent) and online database search experience (novice and experienced) on undergraduate World Wide Web search performance. Considers user factors to predict search efficiency and discusses implications for Web interface design and user training…

We present the design principles for a new kind of computer system that helps students learn algebra. The fundamental idea is to have a system based on the microworld paradigm that allows students to make their own calculations, as they do with paper and pencil, without being obliged to use commands, and to verify the correctness of these…

This report focuses on the user of a prototype hypertext application designed to help coin collectors link ancient coins with relevant numismatic information. It is noted that hypertext systems promote the collection of information that may be multimedia in nature and may be linked so that information can be accessed in a non-linear manner. The…

In 1988 Mann Library at Cornell University proposed to develop a computer system that would support interactive access to significant electronic files in agriculture and the life sciences. This system was titled the Interactive Numeric Files Retrieval System (INFeRS). This report describes how project goals were met and it presents the project's…

Examines how users interact with text to devise a more effective information retrieval interface. Research in cognitive psychology and information science that relates to the use of metaphors and document categorization is reviewed, and an example of text organization and retrieval by historians is presented.

Describes the architecture of the prototype of an image management system that has been used to develop an application concerning images of frescoes in the Sistina Chapel in the Vatican. Hardware and software design are described, the use of local area networks (LANs) is discussed, and data organization is explained. (15 references) (LRW)

Describes an empirical evaluation that investigated the criteria by which designers of human-machine systems evaluate design information. Professional designers of nuclear power plant control rooms rated hypothetical information search questions in terms of relevance, importance, cost, and effort based on Rouse's model of information search…

This project developed a new kind of computer simulation and explored its impact on teaching and learning in introductory biology. The aims of the project were to: (1) develop a flexible simulation environment that would permit students to design, build, and test realistic simulations; (2) support student experimentation with intelligent tutoring…

The development, testing, introduction, evaluation, and refinement of a user interface for a statewide, multi-library online public access catalog network can be a very involved and politically complex enterprise. A multitude of perspectives, assumptions, preferences, and needs accompanies the multitude of players involved, i.e., library…

Discussion of graphical user interfaces for online public access catalogs (OPACs) covers the history of OPACs; OPAC front-end design, including examples from Indiana University and the University of Illinois; and planning and implementation of a user interface. (10 references) (EA)
