Discusses the design of computer applications, focusing on understanding design representations--what makes design representations work, and how, in different contexts. Examines the place of various types of representation (e.g., formal notations, models, prototypes, scenarios, and mock-ups) in design and the role of formalisms and representations…

To support performance for an international audience of computer users, designers need to examine key elements of performance in relation to the design of systems. Discussion focuses on planning ahead for an international audience and preparing a design that keeps the performer, the process, and the information connected, resulting in optimal…

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…

This paper identifies three rationales in the relevant literature for closing the gender gap in computing: economic, cultural and political. Each rationale implies a different set of indicators of present inequalities, disparate goals for creating equality, and distinct principles for software and web site design that aims to help girls overcome…

Within the field of teacher education, there are software designers creating software based on case-based learning theories. This paper examines the difficulties encountered in teacher preparation, and discusses how case-based instruction can address them. It analyzes three software packages designed for case-based teacher education, and discusses…

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…

This paper presents the methods and results of a year-long evaluation study, conducted for the purpose of determining disability accessibility barriers and potential solutions for those barriers found in four World Wide Web-based learning environments. The primary questions used to frame the evaluation study were: (1) Are there any features of the…

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…

The primary purpose of this article is to review the literature on research studies conducted in the last five years on the effectiveness of window presentation strategies and the cognitive dependence status of field-dependent/independent (FD/FI) learners in a computer-mediated instruction (CMI). Secondary to this purpose is to summarize research…

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…
