Describes the PLUTO model, an interactive computer program designed for use in education and training of city planners and engineers. Emphasizes four issues: (1) the balance between realism and simplification; (2) the design of the user interface; (3) comparative advantages of group and solo working; and (4) factors affecting the decision to…

World Wide Web browsers are compared by speed, setup, hypertext transport protocol (HTTP) handling, management of file transfer protocol (FTP), telnet, gopher, and wide area information server (WAIS); bookmark options; and communication functions. Netscape has the most features, the fastest retrieval, sophisticated bookmark capabilities. (JMV)

This study uses the human approach to examine the sources and effectiveness of search terms selected during 40 mediated interactive database searches and focuses on determining the retrieval effectiveness of search terms identified by users and intermediaries from retrieved items during term relevance feedback. (Author/JKP)

Contends that, although technology offers communications options unavailable without an electronic superhighway, it is not a panacea for educators. Discusses technological change and the difficulty for schools to keep up with new developments. Includes recommended reading resources and a selected list of K-12 educational networks. (CFR)

Presents Texas Instruments' new Calculator-Based Laboratory (CBL), a hand-held device that connects to a graphing calculator, as a tool to make sophisticated measurements outside the classroom laboratory. Describes activities that use the CBL to make measurements in motion studies. (JRH)

Describes how the development of a women's studies component for the Gateway to Information (a front-end interface to Ohio State University's online library catalog and other reference sources) minimized the special challenges facing students conducting research on women and changes the focus of bibliographic instruction. (Author/LRW)

Uses a moderately priced digital multimeter that has output and software compatible with personal computers to make a portable, computer-based data-acquisition system. The system can measure voltage, current, frequency, capacitance, transistor hFE, and temperature. Describes field measures of velocity, acceleration, and temperature as function of…

An overview of the development of CD-ROMs is presented. Aspects covered include changes in coverage, the use of CD-ROMs in libraries and information units, changes in search interfaces and growth in end-user searching, changes in CD-ROM publishers, and hardware and networking developments. (Author)

Describes the use of the TI-82 graphics calculator as an intermediate step in introducing computers to the high-school physics lab. Discusses linking the calculator with other machines so that students can save data, enter programs on a computer and later download to the calculator, and transfer graphs to a computer for printing. (JRH)

Proposes a method of evaluating information retrieval systems by concentrating on individual tools (commands, their menus or graphic interface equivalents, or a move/stratagem). A user would assess the relative success of a small part of a search, and every tool used in that part would be credited with a contribution to the result. Cumulative…

Examines the need for virtual workspaces and describes the architecture, design, and development of GroupSystems for the World Wide Web (GSWeb), an HTML/JavaScript Web-based Group Support System (GSS). GSWeb, an application interface similar to a Graphical User Interface (GUI), is currently used by teams around the world and relies on user…

Examines extent to which assessment of text comprehension involves knowledge of the properties of human cognition and the context of assessment. Shows that assessments of the quality of the answers varied based on the perceived human or artificial source of the answers. Provides copies of experimental questionnaires in the appendices. (DSK)

Reviews the Institute for Scientific Information's (ISI) Web interface for its Arts and Humanities, Social Sciences, and Science Citation Expanded citation indexes. Discusses content; other Internet efforts from ISI; pricing; searching; quick and full search modes; using the results; document delivery; full text; documentation and help; and future…

Presents two quantitative Faraday's law experiments using a computer-assisted data-logging system. (Author/ASK)

Presents security procedures for protecting a library's computer system from potential threats by patrons or personnel, and describes how security can be breached. A sidebar identifies four areas of concern in security management: the hardware, the operating system, the network, and the user interface. A selected bibliography of sources on…
