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…

The project DEVISE case study shows how diversity modeling can be used as a powerful design tool. Designers used performance-centered design techniques to create a virtual learning environment in which students with learning disabilities would be more fully supported with an interface that meets their needs. (AEF)

This paper shows how to use design patterns for building educational multimedia applications. The first section summarizes design issues related to organizing the information, the organization of the interface, and implementation. Navigating through information is covered in the second section, including problems, motivations, and solutions, and…

This study examined the effectiveness of spaced practice and spaced review when implemented structurally within a computer assisted instruction (CAI) program. The study viewed the comparison of two levels of CAI as instructional treatments. The instructional treatments were developed as structured, which contained spaced practice and spaced…

Discusses designers' need to design educational software for subversive use, recognizing that users fit the use of technology-based environments into contextually tuned "situated" learning environments. In this sense, good design is volatile design, or design which changes with contextual use. These ideas are illustrated with reference to a range…

Over the past decade, there have been many changes in the tools used to design, the ways information can be represented and the underpinning theories which drive educational experiences. This paper focuses on several examples of software design that have been pedagogically successful and have demonstrated what is possible in software design and…

In January 1999, an interdisciplinary seminar of doctoral students from cognitive, educational and computational sciences was organized to study theoretical texts that might provide insight into how to support collaborative learning with perspectives-based software. The seminar uses a Web-based tool called WEBGUIDE to mediate and structure…

Explores why "learning" and "object" have been combined in the field of instructional technology. Examines why current definitions of these terms are lacking when looked at from a standards and interoperability point of view. Suggests a new definition with a rationale to satisfy needs of technologists for precise, practical…

This article focuses on the effectiveness of computer-based instruction (CBI) screen designs, including their benefits and limitations, as well as human constraints in designing effective CBI. The paper begins with an overview of what comprises an effective CBI screen design, including characteristics of human factors, how information must be…

This paper presents a model for designing computer-based simulation environments within a constructivist framework for the K-12 school setting. The following primary criteria for the development of simulations are proposed: (1) the problem needs to be authentic; (2) the cognitive demand in learning should be authentic; (3) scaffolding supports a…

This paper presents a set of guidelines for the design of computer-supported distance multimedia that enables collaborative distance learning. The first section provides an overview of distance learning and discusses teacher and student roles in a collaborative distance learning environment. Conditions for effective collaborative learning are…

A difficult task in creating rich, exploratory interactive learning environments is building an environment that is truly engaging. Engagement can be defined as the nexus of intrinsic knowledge and/or interest and external stimuli that promote the initial interest in, and continued use of a computer-based learning environment. Complete and total…

This paper introduces a multimedia-based educational system on logistics developed at the University of Magdeburg (Germany), reports on development and implementation of the prototype, and discusses ideas for redesign. The system was tested, used, and evaluated at the university and within a European network of 24 universities, colleges, and…
