Decentralized Service Deployment for Collaborative Environments
In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carrie

The Wellcome Trust Sanger Institute: The Cancer Genome Project
Supported by the Wellcome Trust Sanger Institute, the Cancer Genome Project (CGP) "is using the human genome sequence and high throughput mutation detection techniques to identify somatically acquired sequence variants/mutations and hence identify genes critical in the development of human cancers. This initiative will ultimately provide the paradigm for the detection of germline mutations in non-neoplastic human genetic diseases through genome-wide mutation detection approaches."

MArCo: Building an Artificial Conflict Mediator to Support Group Planning Interactions
The emphasis on building co-operative/collaborative environments has brought out the matter of group interactions. This, in its turn, has highlighted the issue of conflicts, inherent to group problem solving. If well employed, conflicts can act as triggers of cognitive changes, and thus help to refine the group's solution to the task. In this paper, we present a computational framework for detecting and mediating Meta-Cognitive conflicts. The theoretical framework presented here enables a comput

Knowledge Convergence in Computer-Supported Collaborative Learning: The Role of External Representat
This study investigates how two types of graphical representation tools influence the way in which learners use knowledge resources in two different collaboration conditions. In addition, the study explores the extent to which learners share knowledge with respect to individual outcomes under these different conditions. The study also analyzes the relationship between the use of knowledge resources and different types of knowledge. The type of external representation (content-specific vs. conten

The evolution of research on collaborative learning
For many years, theories of collaborative learning tended to focus on how individuals function in a group. More recently, the focus has shifted so that the group itself has become the unit of analysis. In terms of empirical research, the initial goal was to establish whether and under what circumstances collaborative learning was more effective than learning alone. Researchers controlled several independent variables (size of the group, composition of the group, nature of the task, communication

The greenhouse effect visualizer: a tool for the science classroom
The Greenhouse Effect Visualizer (GEV) is designed to help students visualize data sets related to the earth's energy balance. This work was inspired by the benefits scientific visualization have provided to scientists in discovering patterns and presenting the results of their work to broad communities. The hope is that scientific visualization can provide equal assistance to students trying to learn science. The philosophy underlying this approach links learning with practice. Hence, students

Creatures of Habit: A Computational System to Enhance and Illuminate the Development of Scientific T
Creatures of Habit is a computer-based microworld designed to engage middle-to-high school students in the process of scientific inquiry. The system depicts a universe of interacting programmable “creatures” whose individual behavior is guided by simple rules that may model naive psychology, physical laws, chemical affinities, and other domains. Students can create or revise creature rules and explore the resulting (and often surprising) emergent behaviors within “artificial ecosystems”;

Children's mental models of recursive logo programs
Children who had a year of Logo programming experience were asked to think-aloud about what brief Logo recursive programs will do, and then to predict with a hand-simulation of the programs what the Logo graphics turtle will draw when the program is executed. If discrepancies arose in this last phase, children were asked to explain them. A prevaient but misguided "looping" interpretation of Logo recursion was identified, and this robust mental model persisted even in the face of contradiction be

Competence-based Knowledge Structures for Personalised Learning
The ELeGI project focuses on integrating technology-enhanced learning methodologies into a pedagogy-driven and service-oriented architecture based on Grid technology. It aims at a system that is capable of realising personalised, adaptive, and experiential learning. This requires to have available a framework that, on the one hand, allows for representing existing domain knowledge, and, on the other hand, provides a representation of the learner's current state of knowledge. It is shown that a

SCORM and the Learning Grid
The Sharable Content Object Reference Model (SCORM) is a profile of several elearning specification to ensure the reusability and interoperability of elearning content in web based Learning Management Systems (LMSs). Learning grids - learning environments built on the technology of grid services - are a promising new approach to enhance quality of elearning by overcoming the page oriented structure of the web.
