This article argues that accessibility and universality are essential to good Web design. A brief review of library science literature sets the issue of Web accessibility in context. The bulk of the article explains the design philosophies of progressive enhancement and responsive Web design, and summarizes recent updates to WCAG 2.0, HTML5, CSS…

Feedback plays a critical role in student learning and performance. However, providing students with effective feedback is challenging in online environments because of physical separation between students and instructors. Technologies can be used to enhance the effectiveness of feedback in online courses. In this article, we propose effective…

This study investigated how children designed computer games as artifacts that reflected their understanding of nutrition. Ten 5th grade students were asked to design computer games with the software "Game Maker" for the purpose of teaching 1st graders about nutrition. The results from the case study show that students were able to…

We present an approach for teaching design patterns that emphasizes object-orientation and patterns integration. The context of computer game development is used to engage and motivate students, and it is additionally rich with design patterns. A case study is presented based on "EEClone," an arcade-style computer game implemented in Java. Our…

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 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…

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…

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…

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…

This article provides an overview of Telementoring Orchestrator[TM] (TMO), a new web-based software tool designed to aid small or large organizations in supporting telementoring programs (also called online mentoring or e-mentoring programs). In this report, we review the research that inspired the design of the software, and survey the major…

Details a series of tests conducted by the Research Libraries Group, Inc., to evaluate IBM clones i.e., computers designed to use hardware and software originally intended for IBM microcomputers. The results of evaluations of several personal computers, using the criteria of performance, aesthetics, ergonomics, and documentation, are reported.…

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…
