The use of cellular automata to analyze several pre-Socratic hypotheses about the evolution of the physical world is discussed. These hypotheses combine characteristics of both rigorous and metaphoric language. Since the computer demands explicit instructions for each step in the evolution of the automaton, such models can reveal conceptual…

This series of articles reviews the management of global change data and the role of librarians and information professionals. Topics include the Global Change Data and Information System (GCDIS) thesaurus project, ConQuest Software, the Assisted Search for Knowledge (ASK) project, metadata, standards, and Directory Interchange Format and USMARC.…

This article argues that computerized representations of anatomy can integrate both the spatial and symbolic domains of learning better than traditional anatomical representations. A project at the University of Washington is developing a Digital Anatomist Program, multimedia software that can be used on currently-available desktop computers.…

Examines the evolution of multimedia simulation games on floppy disk and CD-ROM, and reviews uses of simulation games for education and entertainment. Discusses what is involved in building, marketing, and playing simulated games. Examples of game screens are displayed throughout the article, and a sidebar lists companies mentioned in the article.…

Evaluates and compares three text-capable Windows-based multimedia CD-ROM authoring tools used by the publishing industry. Reviews product lines, hardware requirements, customer costs, screen designs, product uses, and product advantages and disadvantages. Examples of computer screen designs are displayed throughout the article, and a sidebar…

Presents a discussion of laser disk systems developed by different institutions to store and distribute information and visual images. Includes information on storage, preservation, and use in the classroom or for research. Evaluates image quality, storage capacity, and transmissibility. Urges use of the videodisk to organize information and…

The first of two articles on multiuser access to CD-ROM databases examines options that do not involve a local area network (LAN). Hardware and software requirements, advantages, and disadvantages for several alternatives are described. A product and company directory is included. (MES)

This paper reports on a research and development program which developed a more effective interface between personal computer (PC) users with disabilities and computer systems. The program emulates a PC keyboard, enabling disabled PC users to access standard software via a binary (switch) control element. (Author/DB)

Reviews student use of electronic searching tools and the effect of software changes on user satisfaction and success. Discusses the results of two surveys of InfoTrac users before and after software changes at Northern Illinois University, and proposes three strategies systems developers can take to balance the differing needs of sophisticated…

Describes a study of undergraduates at Aston University (United Kingdom) that investigated whether maps were an appropriate navigational aid for searching in a hypertext environment. Task performance, system use, previous computer experience, perceptions of the system, and cognitive map data are examined; and implications for hypertext system…

Describes the required hardware, software, and configuration of the local area network for information sources and CD-ROMS in the medical libraries at Erasmus University, Rotterdam. Problems encountered with microcomputer diversity, memory requirements, device drivers, and Microsoft Extension software are related; and the network's future growth…

Discusses CD-ROM searching at the University of Charleston; reports the results of a user survey that was conducted to evaluate use of the CD-ROM databases; and describes the design and development of a computer-assisted instruction (CAI) program that explains the basics of searching, retrieving, and printing records using SilverPlatter. (LRW)

A model computer learning center with hardware, software, training, and support components was established to serve as an integral part of the instructional process in Head Start classrooms. The center was found to be a positive force in promoting computer activities, but long-term training and curriculum modifications are needed. (LB)

Describes a nine-week interdisciplinary study of the environment for middle school students, based on the computer simulation "Decisions, Decisions: The Environment," which involves group work, independent work, and a lot of writing. (SR)

The programing language PROLOG is compared to LOGO in terms of its ability to handle mathematical ideas. This is demonstrated by using PROLOG in solving a geometric theorem and two lemmas. The listings of the computer programs used to solve the problems are included. (KR)
