A Hierarchy of Ontologies for Didactics-Enhanced E-learning
Ontologies are a fundamental concept of the Semantic Web envisioned by Tim Berners-Lee [1]. Together with explicit representation of the semantics of data for machine-accessibility such domain theories are the basis for intelligent next generation applications for the web and other areas of interest [2]. Their application for special aspects within the domain of e-learning is often proposed to support the increasing complexity ([3], [4], [5], [6]). So they can provide a better support for course

Gemeinsame Wissenskonstruktion in computervermittelter Kommunikation: Welche Kooperationsskripts fö
Goal of this study is the facilitation of participation and knowledge acquisition in cooperative, computer-mediated learning environments. Two cooperative scripts with respect to discourse contents and interaction were developed to pre-structure communication. Both scripts were analyzed with respect to their influence on participation and application-oriented knowledge in computer-mediated learning environments. The factors "content-related cooperative script" and "interaction-related cooperativ
Cooperation scripts for learning via web-based discussion boards and videoconferencing
Computer-supported collaborative learning often means that locally distant learners discuss a task via text-based discussion boards or videoconferencing. Collaborative learning, however, is often suboptimal with respect to how learners work on the concepts that are supposed to be learned and how learners interact with each other. Collaborative learning environments may be improved by scripts that structure epistemic activities and social interactions of learners. Two studies are being reported t
Analyzing Sequential Data in Computer-Supported Collaborative Learning
Representations and changes between them play a major role in cognitive development (e.g., Vosniadou, & Brewer, 1992) and education (e.g., Hewson, Beeth, & Thorley, 1998). By definition, change of representations is also indispensable for collaborative work since a common understanding or shared knowledge can only be achieved by a partial convergence of the knowledge structures of the collaborating subjects. This articles presents and discusses knowledge tracking (KT), viz., an approach to analy
"What I think works well...": LearnersÂ’ evaluation and actual usage of online tools
This paper will describe and analyse data gathered during a pilot language course run fully online and based on a Moodle VLE. The new online tools, whether as part of an integrated VLE or separately, lend themselves to reflective learning (e.g. blogs) or collaborative group activities (e.g. wikis). This case study of two learners is based on the project “CyberDeutsch” at the Department of Languages of the Open University, a five week, intensive German course offered to self-selected intermedia
The use of a computerized brain atlas to support knowledge-based training in radiology
Trainers of radiologists face the particular challenges of teaching normal and abnormal appearance for a variety of imaging modalities, providing access to a large appropriately-indexed case library, and teaching a consistent approach to the reporting of cases. The computer has the potential to address these issues, to supplement conventional teaching of radiology by providing case-based tutoring and diagnostic support based on a large library of images of normal and abnormal anatomy, fully desc
Anchored Interactive Learning Environments
Advances in computer technology and multi-media systems have led to widespread interest in computer-based instruction and learning environments. The use of video, animation, graphics, and simulation allow the presentation of material in realistic contexts, thus addressing the problems of inert knowledge while promoting constructive and generative learning. But the true potential and benefits of these systems are yet to be realized. Cognitive studies on learning and transfer suggest that concepts
Task and Interaction Regulation in Controlling a Traffic Simulation
In collaborative problem solving, metacognition not only covers strategic reasoning related to the task but also reasoning related to the interaction itself. The hypothesis underlying this work states that regulation of the interaction and regulation of the task are closely related mechanisms and that their co-occurrence facilitates collaborative problem solving. These assumptions are tested experimentally with a traffic simulator. The results show that co-occurrence of task and interaction regu

Bethune Academy's Weather Center (1) discusses the functions of psychrometers, anemometers, weather balloons, thermometers, and barometers. The Illinois State Water Survey (2) furnishes many images of various instruments that collect data daily for legal issues, farmers, educators, students, and researchers. The th

With the exception of orchestral performances and truly "unplugged" concerts, today's music has evolved into a very hi-tech industry. It takes elements from many disciplines, including computer science, electrical and mechanical engineering, mathematics, and physics. Because music technology encompasses everything from audio compression and encoding to advanced sound equipment, this Topic in Depth has quite a broad scope.A decent introduction to some aspects of music technology (1) mainly deals
Mechanisms of common ground in case-based web-discussions in teacher education
Previous studies suggest that before the participants in Web-based conferencing can reach deeper level interaction and learning, they have to gain an adequate level of common ground in terms of shared mutual understanding, knowledge, beliefs, assumptions, and presuppositions (Clark & Schaefer, 1989; Dillenbourg, 1999). In this paper, the main purpose is to explore how participants establish and maintain common ground in order to reach deeper level interaction in case-based Web-discussions. The s

Distance learning and foreign language teaching
Among numerous modes of technology enhanced learning there are not many that have received as much attention as distance learning. Stimulated by the recent rapid developments in Web technologies, researchers in both ICT and education are constantly working to make the most of technological resources and put them to the best pedagogical use. In the area of foreign language teaching a lot has been done to cover a variety of world languages, but there are constant attempts for new solutions, taking
