In this paper we present a CDN-based system, namely the COMODIN system, which is a media on-demand platform for synchronous cooperative work which supports an explicitly-formed cooperative group of distributed users with the following integrated functionalities: request of an archived multimedia session, sharing of its playback, and collaboration…

This paper examines the design and evaluation of a TV on Demand (TVoD) system, consisting of a globally accessible storage architecture where all TV content broadcast over a period of time is made available for streaming. The proposed architecture consists of idle Internet Service Provider (ISP) servers that can be rented and released dynamically…

Streaming audio/video contents over the Internet requires large network bandwidth and timely delivery of media data. A streaming session is generally long and also needs a large I/O bandwidth at the streaming server. A streaming server, however, has limited network and I/O bandwidth. For this reason, a streaming server alone cannot scale a…

Technological improvements in broadband and distributed computing are making it possible to distribute live media content cost-effectively. Because of this, organizations are looking into cost-effective approaches to implement e-Learning initiatives. Indeed, computing resources are not enough by themselves to promote better e-Learning experiences.…

This paper describes the origin and work of an independent research and development facility whose role is to catalyse the development of broadband applications for education. The paper describes how a three pronged approach is helping content developers understand the opportunities and make use of good research and practice in learning to develop…

Despite some spectacular e-learning failures in recent years, e.g. the British government's "e University", educational technologies have continued developing and have made advances in several learning paradigms. These new learning paradigms appear as new ways to deal with the old traditional learning concepts and philosophies throughout the…

The evolution of Internet Technology has influenced the basis of education by introducing new methodologies in to teaching and giving a new dimension to distance learning. On the other hand, there is an emerging need on the users part to define some standards that will be used for judging the quality and effectiveness of the educational Websites.…

In this paper we present an account of an undergraduate team-based assignment designed to facilitate, exhibit and record team-working skills in an e-mediated environment. By linking the student feedback received to Hofstede's classic model of cultural dimensions we aim to show the assignment's suitability in revealing the student's multi-cultural…

One of today's major problems in the field of e-learning is that the creation of high-quality content is still rather time consuming and expensive. In the past, many efforts have been made to produce educational content on the fly, but the results were mainly static blocks of recorded lecture lacking sophisticated navigation facilities. Facing…

This article presents the first stage of a design-based research project to introduce case-based learning using existing interactive technologies in a major Australian university. The paper initially outlines the relationship between case-based learning, student interaction and the study of interactions--and includes a review of research into…

Collaborative Learning in group settings currently occurs across a substantial portion of the UK Higher Education curriculum. This style of learning has many roots including: Enterprise in Higher Education, Action Learning and Action Research, Problem Based Learning, and Practice Based Learning. As such our focus on Collaborative Learning…

Distance learning has been widely researched the past few years, nevertheless the focus has been more on its technological dimension. Designing, developing and supporting a large scale e-learning application for Higher Education is still a challenging task in many ways. E-learning is data-intensive, user-driven, and has increasing needs for…

During oral exams at the German distance learning university, we noticed that students fear that they will be faced with questions that they have not anticipated. In our opinion, this is mainly because students have no chance to train and thereby gather positive experiences with exam situations as they are distributed all over Germany and thus it…

This paper reports on how prospective users may be involved in the design of entertaining educational computer games. The paper illustrates an approach, which combines traditional Participatory Design methods in an applicable way for this type of design. Results illuminate the users' important contribution during game development, especially when…

Educators recognize that group work and physical involvement with learning materials can greatly enhance the understanding and retention of difficult concepts. As a result, math manipulatives--such as pattern blocks and number lines--have increasingly been making their way into classrooms and children's museums. Yet without the constant guidance…
