Viewing high-resolution images on the World Wide Web at a level of detail necessary for collaborative research is still a problem today, given the Internet's current bandwidth limitations and its ever increasing network traffic. ImageEyes is an interactive display tool being developed at Utah State University that addresses this problem by…

The architecture of a web-based course management tool that has been developed at IIT [Indian Institute of Technology], Kharagpur and which manages the submission of assignments is discussed. Both the distributed architecture used for data storage and the client-server architecture supporting the web interface are described. Further developments…

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…

Background: The idea for attempting a distance tutoring project between university tutors and elementary school students using Microsoft NetMeeting was conceived: (a) to provide a new experience mentoring children for university students pursuing a teaching certificate, (b) for university students to utilize technology in pedagogy, (c) as an…

This paper describes the features of the 1996 version of an intelligent tutoring system (ITS) called CALAT. The architecture of CALAT is an extension of conventional World Wide Web systems, consisting of an ITS kernel on the server side and a multimedia viewer on the client side. The viewer control system is designed to achieve both educationally…

The Virtual Workshop is a World Wide Web-based set of modules on high performance computing developed at the Cornell Theory Center (CTC) (New York). This approach reaches a large audience, leverages staff effort, and poses challenges for developing interesting presentation techniques. This paper describes the following techniques with their…

This report examines subsections of the computer network topology that relate to end-to-end performance and capacity planning in schools. Active star topology, Category 5 wiring, Ethernet, and intelligent devices are assumed. The report describes a model that can be used to project WAN (wide area network) connection speeds based on user traffic,…

Describes the use of "Graphical" Jogthrough method for evaluating the user-interface design of the Network Simulator, an educational simulation program that enables users to virtually build a computer network, install hardware and software components, make necessary settings, and test the functionality of the network. Presents evaluation results…

Voice over Internet Protocol (VoIP) is everywhere. The technology lets users make and receive phone calls over the Internet, transporting voice traffic alongside data traffic such as instant messages (IMs) and e-mail. While the number of consumer customers using VoIP increases every week, the technology is finding its way into K-12 education as…

This article investigates three types of content presentation (video documentary, computerized dictionary, and games) within interactive computer use at the Quebec Museum of Civilization. The visitors' viewpoint is particularly relevant for interface designing outcomes, since they argued that terminals require specific content display for…

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…

In 1997, the Software Engineering Laboratory at Pontifical Catholic University of Rio de Janeiro (Brazil) implemented the first version of AulaNet (TM) a World Wide Web-based educational environment. Some of the teaching staff will use this environment in 1998 to offer regular term disciplines through the Web. This paper introduces Quest, a tool…

This paper discusses psychological effects associated with the latest technology in computer interfaces. Emphasis is given to issues involved with multi-media systems and the development of the self on emotional, intellectual, and social levels. A review of technology attitudes and individual differences is presented in relation to the voluntary…
