This Proceedings contains 53 of the 67 papers reviewed and selected by the Organizing/Reviewing Committee for presentation at the National Online Meeting, 1999. The volume begins with the introductory presentation by the Program Chairman, Martha E. Williams, "Highlights of the Online Database Industry and the Internet 1999." The balance of the…

Describes a study conducted at Ohio State University libraries that gauged success using the Library Resources Network by having 43 users complete an exercise that forced them to make database selections, use a variety of database interfaces, and select appropriate terminology. Sample screen displays and the questionnaire used are appended.…

Presented are four activities which are designed to familiarize children with the multiple uses of computers and help them learn about heat and temperature using temperature probes. Included are the tempering effect of water, heat capacity, caloric content of foods, and weather. Hardware and software are discussed. (CW)

Described are 14 experiments that use lasers. Topic areas include physical chemistry, analytical chemistry, organic chemistry, inorganic chemistry, and biochemistry. Instrumentation and the use of the laser in undergraduate research are discussed. (CW)

Presented are 29 science activities for secondary school science instruction. Topic areas include botany, genetics, biochemistry, anatomy, entomology, molecular structure, spreadsheets, chemistry, mechanics, astronomy, relativity, aeronautics, instrumentation, electrostatics, quantum mechanics, and laboratory interfacing. (CW)

Described is a means of logging data from remote sensors in data files and then transferring the data to a spreadsheet for processing. The presentation of the data in tabular or graphical form is discussed. An example using temperature data from a model house is provided. (Author/CW)

Introduces microcomputer interfacing as a method for explaining and demonstrating various aspects of the concept of function. Provides three experiments with illustrations and typical computer graphic displays: pendulum motion, pendulum study using two pendulums, and heat absorption and radiation. (YP)

Examines how metacognitive theory can be integrated into the design of computer-based learning environments through the user interface. Highlights include interface design, metacognition and cognitive processes, using metaphors, user access to information, visual feedback, navigational tools, interaction styles, menus, and self-evaluation methods.…

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…

Research in human-computer interaction is evolving a user-centered methodology for system design and instruction that focuses on integrating affective and cognitive user variables to increase productivity, creativity, and human growth. Discussion includes the survey approach, the experimental-ethnographic approach; theory-building; and the future…

Discussion of Web-based online public access catalogs (OPACs) focuses on a review of six Web OPAC interfaces in use in academic libraries in the United Kingdom. Presents a checklist and guidelines of important features and functions that are currently available, including search strategies, access points, display, links, and layout. (Author/LRW)

Reports on the evaluation of a computer-based learning system at the University of Dundee (Scotland) used for computing courses. Describes use of the World Wide Web, tutorials, interface, motivation, perceived value in relation to lectures and laboratories, student attitudes, improvements made as a result of the evaluation, and future work. (LRW)

Most large enterprises now have some type of portal to organize their internal information services. Few, however, have the long history of the SPIKE project at the University of Pennsylvania's Wharton School. Originally developed during the 1994-1995 school year, SPIKE was an intranet information portal before the term "information…

Sixteen courses were taught over a 2-year period at eight universities using Perseus, a HyperCard-based hypermedia information system that contains multimedia information about the Greek world, in order to examine how type of assignment influenced student perceptions about the Perseus interface and learning performance. Data collection methods…

A study of nine different image maps from World Wide Web home pages was conducted to evaluate their effectiveness in information display and access, relative to visual, navigational, and practical characteristics. Nine independent viewers completed 20-question surveys on the image maps, in which they evaluated the characteristics of the maps on a…
