Quality of Service Requirements for the e-Learning Grid
In the same way that the Web has evolved from being a technology designed to aid scientific collaboration to one which is employed extensively in e-business and increasingly in e-learning, the Grid is also evolving from its original concept as a highly distributed dynamic source of computing resources "on tap", like the power grid, for e-science, to a means of supporting enterprise computing across heterogeneous, distributed, virtual organisations. However, even the most recent ideas associated
Shaping e-Learning Applications for a Service Oriented GriD
The paper discusses technical issues related to establishment of e-learning services on a grid. The XML based technology for implementation of e_learning application in the form of web service is analyzed from the perspective of making an application grid-aware. The special e_learning repository service is proposed as a technique for coordinated use of distributed e_learning resources through the access and invocation of web services.
A model for negotiation in teaching-learning dialogues
Despite the fact that a number of researchers from a wide variety of theoretical perspectives have claimed that negotiation in dialogue is fundamental in learning, little research has been based on a precise notion of what negotiation is and how it relates to learning. This paper describes a model for negotiation, based on analysis of teacher-student and learner-learner dialogues. After discussion of illustrative examples and review of related research, negotiations are defined in terms of four
A note on organizational learning and knowledge sharing in the context of communities of practice
The knowledge management (KM) literature emphasizes the impact of human factors forsuccessful implementation of KM within the organization. Isolated initiatives for promoting learning organization and team collaboration, without taking consideration of the knowledge sharing limitations and constraints can defeat further development of KM culture. As an effective instrument for knowledge sharing, communities of practice (CoP) are appearing to overcome these constraints and to foster human collabo
Vers une approche déclarative pour les logiciels de dessins géométriques
Cet article est consacré à la conception d'un environnement d'apprentissage de la géométrie orienté vers la manipulation directe de figures géométriques. À travers deux exemples d'activités, proposées en classe, on distingue les notions de construction géométriques, de spécification, et de manipulation directe. Dans le cadre ainsi défini, nous présentons notre approche. Elle consiste à intégrer des mécanismes et la méthodologie de l'intelligence artificielle dans un logic
An Evolutionary Approach to Prototyping Pedagogical Agents: From Simulation to Integrated System
We have developed and integrated software agents with two educational groupware systems (TeamWave Workplace and FLE), using evolutionary prototyping and empiricalbased design as development techniques. The resulting prototypes of pedagogical agents (CoPAS, SA-Agent and RuleEditor) provide learners and teachers with increasingly domain-specific support for distributed collaborative learning activities. Employing the evolutionary approach has enabled us to build and evaluate early prototypes of co
Didactical complexity of computational environments for the learning of mathematics
How a microworld is used by students is crucially influenced by the teacher, who has the responsibility of organising the classroom setting in which learning takes place. For this reason this paper focuses on the teacher as a manager of the learning situation, in relation to the students’ construction of meaning. A model of teaching which takes into account interactions between teacher, students and computer is outlined. Although the focus of this paper will be on the teacher, the teacher w
Interdisciplinary approach for the design of a learning environment
This paper presents our interdisciplinary approach for the design of a technology-based learning environment for orthopaedic surgery. We present how the didactical analysis of teaching and learning in workplace gives a framework to build the computational representation of knowledge. This analysis is shown within the context of the apprenticeship of concepts of anatomy and orthopaedic surgery.
Internal and external cooperation scripts in web-based collaborative inquiry learning
Cooperation scripts are a powerful means to improve collaborative learning. Scripts can be designed to support argumentative knowledge construction. However, not only externally induced cooperation scripts but also the learners internal scripts on argumentative knowledge construction influence argumentative processes and what kind of knowledge is acquired during collaboration. In this study, 98 students (49 dyads) of two German secondary schools participated. We implemented two versions (high
Socioemotional orientation as a mediating variable in teaching learning interaction: Implications fo
In this paper we argue that many of the design decisions of modern pedagogical solutions are made unconsciously without articulated view of the issues being addressed by the complex relationship of student’s social, emotional and motivational interpretations in learning. We present a theoretical framework for analysing them and discuss of the two empirical experiments, where individual students’ social and motivational interpretations were analyzed in a cognitive apprenticeship based technol
Livre blanc sur les standards du e-learning
L’article suivant propose un tour d’horizon sur les différents standards émergents du secteur de l’eLearning. Comme toute nouvelle technologie, l’eLearning et ses différentes fonctionnalités doivent pouvoir disposer d’un schéma de référence standard. L’existence d’un tel standard est indispensable au développement d’une nouvelle technologie, en le sens qu’il permet l’interopérabilité de ressources vouées autrement à être incompatibles. L’interopérabilité est
Visual aid for mapping your position within a learning cycle.
Elements that make up the human body
Introducing the periodic table of elements, and identifying the major elements involved in the human body and their roles.
Equations - Calculations with numbers and symbols
A learning object that concentrates on your ability to do calculations in the right order.
Robotics with the XBC Controller
This course offers a brief history of robotics, and a definition of robot and robotics. The course includes an introduction to IC and the XBC, downloading firmware, Updating the bitstream, and IC Environment and simulator. It concludes with an activity building a Demo-Bot.
Using Pseudoscience as an Aid to Teaching General and Analytical Chemistry
This site developed by Michael Epstein, Margaret Bullard, Brad Buehler, and Robin Kloster, Department of Science, Mount Saint Mary\'s College contains case studies and experiments, used at this college in Maryland, that could be readily incorporated into an analytical chemistry course. Their inclusion of pseudoscientific topics include (a) lecture, discussion, and examinations; (b) demonstrations; (c) laboratory experiments; and (d) student attendance at a conference where controversial research
Introduction to Chemical Equilibria
An interactive set of applet-based demonstrations (many modeled as experimental measurements) that illustrate the concepts and calculations of chemical equilibria. The site demonstrates equilibrium processes in a reaction vessel by plotting the concentration of reactants and products over time. The site would be a good supplement for a class in general chemistry or quantitative analysis.
Drug company GlaxoSmithKline offers this online genetics tutorial designed for kids. The tutorial presents lessons on DNA, genes, heredity, genetic susceptibility to disease, and the role of genetic markers in predetermining risk of disease and medicinal response. Each subject page includes a description of the topic, plus loads of interactive educational games and activities. The educational games are especially well done, although the cartoon-style presentation, which is intended for younger s
Introduction to Mass Spectrometry
This site contains an on-line text on mass spectrometry at the intermediate level. The text gives good general coverage of mass spectrometry instrumentation and applications in very readable format. It contains nice diagrams that provide a visualization of the ionization and mass selection processes. It also contains an overview of applications of mass spectrometry near the end that is different than most sites related to MS. It is especially appropriate for intermediate students.
