New tools in Social Practice: Learning, Medical Education and 3D Environments
Learning with different kinds of ICT-based tools is an important issue in todayÂ’s society. In this article we focus on how design of technology rich environments based on state of the art learning principles can give us new insights about how learning occur, and how we can develop new types of learning environments. Medical education constitutes the subject domain. There has been a considerable effort to develop 3D technologies in this field, and the article provides a careful review of how the
Gridcole: a tailorable grid service based system that supports scripted collaborative learning
This paper introduces Gridcole, a new system that can be easily tailored by educators in order to support the realization of scripted collaborative learning situations. To do so, educators can provide a script specifying the sequence of activities to be performed by learners as well as the tools and documents required to support them. Gridcole can then search for these tools in a service-oriented grid in order to integrate them so that they are available for users during the realization of the s
Towards Web 2.0 Schools: Rethinking the Teachers Professional Development
This paper aims at analyzing the Web 2.0 based distance education in the K-12 schools as an emerging phenomenon that catalyzes a new educational reform all over the world. Some pre-Web 2.0 best practice examples are analyzed in order to draw the main findings in the paper. The teacherÂ’s professional qualification designed to meet the new challenges is considered as a key problem for a successful penetration of this phenomenon in the schools. It is emphasized on the importance of designing a lif
Combining heuristics and formal methods in a tool for supporting simulation-based discovery learning
This paper describes the design of a tool to support learners in simulation-based discovery learning environments. The design redesigns and extents a previous tool to overcome issues that came up in a classroom learning setting. The tool focuses on supporting learners with experimentation to identify or test hypotheses. The aim is not only to support learning domain knowledge, but also learning discovery learning skills. For this purpose the tool uses heuristics and formal methods to assess the
Embedding email in primary schools: developing a tool for collective reflection
Reflection is an important aspect of learning in groups. In collective moments of reflection, learners can share and compare their ideas with others, and by doing so can reach an articulated and personal understanding of a learning task and domain. In the research presented here, e-mail is examined as a means for reflection in the context of group learning. In two design experiments, an e-mail tool is developed that seeks to (1) support collective reflection, and (2) overcome practical problems
Problems and Opportunities of Learning together in a Virtual Learning Environment
This chapter explores new ways of collaborative learning in a virtual learning environment based on our acquisition of knowledge from previous experience. We identify both the problems faced in real collaborative learning practices and the ways these problems can be overcome and become opportunities for more efficient learning. These issues concern pedagogical, organisational and technical elements and constraints that influence the successful application of collaborative learning in distance ed
Collaborative distributed environments for learning design tasks by means of modelling and simulatio
The Simulation discipline has to face new challenges such as the incorporation of Collaborative Technologies for professional use as well as for teaching purposes. This integration permits the creation of new kinds of support for collaborative learning processes. In this paper, we explore the potential of this synergy with DomoSim-TPC, a synchronous distributed collaborative environment for the teaching and learning of Domotics. The system supports an active, simulation-based and problem-based a
Open Distance Inter-University Synergies Between Europe, Africa and the Middle East (ODISEAME)
The challenge facing new technologies is whether they can contribute to a qualitative step up and to education for all as a process of facilitating the development of creative people with the ability to think critically and to engage in socially relevant decision making. In this paper, we describe a project whose purpose is to develop a learning environment that takes into account current expertise in learning theory in order to facilitate productive collaboration in a way that leads to active c
Computerized scripts for enhancing collaborative learning
Free collaboration does not systematically produce learning. One way to enhance the effectiveness of collaborative learning is to structure interactions by engaging students in well-defined scripts. A collaboration script is a set of instructions prescribing how students should form groups, how they should interact and collaborate and how they should solve the
problem. In computer-supported collaborative learning (CSCL), the script is reified in the interface of the learning environment. This co
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
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
Grid and Peer-to-Peer middleware for Cooperative Learning Environments
This paper presents the work done by the research group of the Open University of Catalonia within the coordinated project towards the definition of adequate grid and peer-to-peer middleware for cooperative learning environments. The main results of our research consist in designing a layered framework for modelling online collaborative learning interactions which in turns leads to the development of a computational platform, called Collaborative Learning Purpose Library (CLPL), that can be used
A Model for the Efficient Representation and Management of Online Collaborative Learning Interaction
This study aims to explore the importance of the efficient representation and management of the event information generated from group activity in online collaborative learning practices so that we can use it to provide awareness about individual and group behaviour. The achievement of this goal first involves the design of a conceptual model of collaborative learning interaction that structures and classifies the information generated in an online collaborative learning situation at several lev
Gridifying IBM's Generic Log Adapter to Speed-Up the Processing of Log Data
Problem determination in today's computing environments consumes between 30 and 70% of an organizationÂ’s IT resources and represents from one third to one half of their total cost of ownership. The first step to cutting down costs in this area and to enable autonomic computing systems is to have all parts of the system report status in a common log data format and semantics in order to be able to exploit the status information of the system as a whole. The Generic Log Adapter (GLA) is a generic

Matching Technologies for Enhancing the
Automatic Composition of
In the implementation of e-learning frameworks, a problem still unsolved is how to use and integrate low-level learning services to compose more complex high-level services or tools that make sense to both tutors and learners. In that sense semantic description of Grid learning Services appears like a powerful tool to be used for discovering and matching learning services depending of a set of parameters inside the learning framework. These parameters must represent significant functional charac
An Experimental Study on Peer Selection in a P2P Network over PlanetLab
Peer selection is an important aspect in many P2P applications
requiring efficient assignment and execution of
jobs to peer nodes and search and file transfer, among others.
Due to increasing interest of using P2P systems for distributed
computing, peer selection is taking relevance and
several models have been proposed in the P2P literature.
Yet, there are very few experimental studies for peer selection
in P2P networks deployed in real large scale networks.
In this work we present an experimen
Semantic Description of Grid Based Learning Services
Grid technology has emerged as a powerful tool to increase the
capabilities of e-learning frameworks. Learning services are fundamental
components representing functionalities that can be easily reused without
knowing the details of how services have been implemented. On the one hand, a
problem that still remains unsolved is how to use and integrate low-level
learning services to compose more complex high-level services or tools that
make sense to both tutors and learners. On the other hand, the
Enabling Efficient Real Time User Modeling in On-line Campus
User modelling in on-line distance learning is an important research
field focusing on two important aspects: describing and predicting studentsÂ’ actions
and intentions as well as adapting the learning process to studentsÂ’ features,
habits, interests, preferences, and so on. The aim is to greatly stimulate
and improve the learning experience. In this context, user modeling implies a
constant processing and analysis of user interaction data during long-term learning
activities, which produces l
Collaboration Activity Function: An interaction analysisÂ’ tool for Computer Supported Collaborative
During the last years, an increased interest has been observed on tools analyzing collaborative interactions that could be useful for researchers, teachers, or even students. The paper presents such a tool, based on the formally defined collaborative activity function (CAF). The empirical evaluation of CAF is also presented. The evaluation is focused on teachers using CAF during and after sessions of synchronous collaborative problem solving among students.
Obstacles to the development of conceptual understanding in observational astronomy: the case of spa
Simple everyday phenomena like the day - night cycle and the sequence of four seasons are taught at the higher level of elementary education and the lower level of secondary education in Cyprus. Even though there is no specific subject dedicated to Astronomy or spatial reasoning, the day – night cycle, the sequence of the four seasons and the sequence of the lunar phases are part of the national curriculum of Geography. For this reason, the construction of conceptual understanding in basic Astr
