Cowos: A Model of Collective Work Situations to Support Modelling and Simulation Based Approaches of
This paper describes an operational model of collective work situations. This model is rooted in the CHAT theory. It allows creating multi-agent simulations where the agents’ behaviour is defined in terms that make salient organization issues, and allows building learning situations that focus on making students consider explicitly these issues.

Structural Awareness for Collaborative Learning Environments
In this paper we propose a peer-to-peer support approach that we call structural awareness support. The structural awareness aims to support the communication that takes place in virtual learning communities. Its emphasis is on revealing the group structure to its participants in order to promote collaborative interactions. This support has been implemented on a forum type tool called Mailgroup. It has been tested twice in different contexts, obtaining initial feedback of its pertinence accordin

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

Providing Efficient Event Information Management to CSCL Applications
This work aims to explore the importance of carrying out an efficient management of the event information generated from CSCL applications during the collaborative learning process. The achievement of this task first involves the design of a conceptual model of collaborative learning interaction that captures and distinguishes several high-level collaborative learning processes, which in turns leads to a computational model. To achieve that, we first define the main types of event information ge

Regulative support during inquiry learning with simulations and modeling
Many factors impact learning; the environment and resources available, the domain, how much prior-knowledge a student has, and how well they make use of their metacognitive skills, all of these factors impact new knowledge creation. The series of studies described in this dissertation focuses on the latter; i.e. the metacognitive skillfulness of students. Known collectively as self-regulation, planning, monitoring, and evaluation, when applied appropriately will enhance learning. Students who m

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

Towards a Generic Platform for Developing CSCL Applications Using Grid Infrastructure
The goal of this paper is to explore the possibility of using CSCL component-based software under a Grid infrastructure. The merge of these technologies represents an attractive, but probably quite laborious enterprise if we consider not only the benefits but also the barriers that we have to overcome. This work presents an attempt toward this direction by developing a generic platform of CSCL components and discussing the advantages that we could obtain if we adapted it to the Grid. We then pro

A Parallel Grid-based Implementation for Real Time Processing of Event Log Data in Collaborative App
Collaborative applications usually register user interaction in the form of semi-structured plain text event log data. Extracting and structuring this data is a prerequisite for later key processes such as the analysis of interactions, assessment of group activity, or the provision of awareness and feedback. Yet, in real situations of online collaborative activity the processing of log data is usually done offline since structuring event log data is, in general, a computationally costly process

Supporting Effective and Useful Web-based Distance Learning
Learners interacting in a Web-based distance learning environment produce a variety of information elements during their participation; these information elements usually have a complex structure and semantics, which makes it rather difficult to find out the behavioral attitudes and profiles of the users involved. User modelling in on-line distance learning is an important research field focusing on two important aspects: describing and predicting students’ actions and intentions as well as ada

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 organization’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

Exploring Semantic Description and 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

Efficient Embedding of Information and Knowledge into CSCL Applications
This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, on the other hand, to extract the relevant knowledge in order to provide learners and tutors with efficient awareness and support as regards collaboration. To this end, we first identify and define the main types of information generated in online group activity and then propose

Towards automatic glossarization: automatically constructing and administering vocabulary assistance
We address an important problem with a novel approach: helping children learn words during computer-assisted oral reading. We build on Project LISTEN's Reading Tutor, which is a computer program that adapts automatic speech recognition to listen to children read aloud, and helps them learn to read (http://www.cs.cmu.edu/~listen). In this paper, we focus on the problem of vocabulary acquisition. To learn a word from reading with the Reading Tutor, students must first encounter the word and then l

Bridging the Gap Between Empirical Data on Open-Ended Tutorial Interactions and Computational Models
In this paper we present an approach to using empirical data on human teacher-learner interactions to guide the development of a pedagogical agent for supporting musical composition learning. Our approach to bridging the gap between tutorial interaction analysis and computational models, intended for use in learning support systems, is a new one. We support our claim by pointing out that most of the previous work in the area of using human tutors as models has been conducted in domains that are

Exploring novice users' training needs in searching information on the World Wide Web.
Searching for information on the WWW involves locating a website and locating information on that site. A recent study implied that novice users' training needs exclusively relate to locating websites. The present case study tried to reveal the knowledge and skills that constitute these training needs. Fourteen pre-university students, classified as novice (n = 7) or experienced WWW-user (n = 7) performed three web search tasks. Their actions and verbalisations were recorded. Between-group compa

Determining the Sources of Delay in a Distributed Learning Environment
In the context of LeGE-WG we expect to see the Open Grid Services Architecture (OGSA) being used as a guiding framework for the future deployment of Distributed Learning Environment (DLEs). OGSA is totally service-oriented and it has been known for sometime that Quality of Service (QoS) is key to the success of DLEs. Delay in particular, as experienced by the end user, is one of the key QoS parameters for a DLE. This paper describes techniques for identifying sources of such delay, and a model f
