This paper discusses the need for and the design requirements of generic chatroom software that is readily configurable to particular domains and that is also extensible. The architecture of a client/server chatroom generation system, ChatterBox, implemented in Java, is presented. The following components of ChatterBox are described: (1) the basic…

This paper describes the design and implementation of an object-oriented World Wide Web-based CAI (Computer-Assisted Instruction) system. The goal of the design is to provide a flexible CAI/ITS (Intelligent Tutoring System) framework with full extendibility and reusability, as well as to exploit Web-based software technologies such as JAVA, ASP (a…

Providers of online information with a high visual content face an uncompromising dilemma--how to achieve fast delivery while maintaining good picture quality. As storage space or bandwidth increases, the demands placed on it by the user are always two steps ahead. Since limited bandwidth for communicating images looks like it may remain a problem…

AHA! is a simple Web-based adaptive hypermedia system. Because of this simplicity it has been studied and experimented with in several research groups. This paper identifies shortcomings in AHA! and presents AHA! version 2.0 which tries to overcome the known problems with AHA! while maintaining its biggest asset: simplicity. The paper illustrates…

Illustrates the design and implementation of a Java applet for use in educational propulsion engineering curricula. The Java Gas Turbine Simulator applet provides an interactive graphical environment which allows the rapid, efficient construction and analysis of arbitrary gas turbine systems. The simulator can be easily accessed from the World…

Discusses one approach to project organization providing a baseline lifecycle model for multimedia/CBT development. This variation of the standard four-phase model of Analysis, Design, Development, and Implementation includes a Pre-Analysis phase, called Definition, and a Post-Implementation phase, known as Maintenance. Each phase is described.…

Proposes a framework for commercial Web application development based on prior research in hypermedia and human-computer interfaces. First, its social acceptability is investigated. Next, economic, technical, operational, and organizational viability are examined. For Web-page design, the functionality and usability of Web pages are considered.…

Explores the utility of the intersection of genre theory and cognitive psychology in providing a meaningful framework for analysis and design purposes. Reports results of research into the elements of genre that influence users of digital documents and provides examples of the usefulness of this analysis in Web-based environments. (Author/AEF)

This paper describes the design of a synchronous World Wide Web-based distance education environment developed at the Telematics Laboratory of Computer Engineer and Informatics Department (CEID) and Computer Technology Institute (Greece); the environment uses telematics services to conduct lessons over computer networks, simulating a traditional…

This paper describes the design and implementation of a real time on-line collaboration tool, EDUCO. The main focus is to demonstrate how the tool is applied to a real life on-line distance education course, discuss the preliminary research findings of the qualitative empirical study, propose directions for future work and discuss implications.…

Discusses online testing using the inQsit[C] Web-based software system, a system that enables an individual to create an assessment module, administer that module to gather responses, and perform simple analyses with responses. Describes how to create an online test using inQsit[C]; administering the test; grading the tests; concerns/problems…

This paper describes the first stage of a 4-year research project on the design, development and use of Web-based digital learning material for food chemistry education. The paper discusses design guidelines, based on principles that were selected from theories on learning and instruction, and illustrates in detail how these guidelines were used…

This paper provides an analysis of old and new programming tools for development of client/server programs, particularly World Wide Web-based programs. The focus is on development of educational systems that use interactive shared workspaces to provide portable and expandable solutions. The paper begins with a short description of relevant terms.…

In this paper, a Web-based learning environment developed within the project called Virtual Learning Spaces (EVA, in Spanish) is presented. The environment is composed of knowledge, collaboration, consulting, experimentation, and personal spaces as a collection of agents and conventional software components working over the knowledge domains. All…

This paper describes the IFLA (International Federation of Library Associations and Institutions) guidelines for librarians charged with customizing OPAC (online public access catalog) software and vendors and producers of this software. The guidelines are intended to apply to all types of catalog, including World Wide Web-based catalogs, GUI…
