Redefining the Turn-Taking Notion in Mediated Communication of Virtual Learning Communities
In our research on social interactions taking place in forum-type tools that virtual learning communities use, we have found that the users have the following particular temporal behavior: they answer generally some messages situated in different threads in a very short time period, in a digest-like way. This paper shows this work pattern through a quantitative study and proposes an integration of this work pattern in a Forum-type tool developed for supporting the interactions of virtual learnin

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.

Cognitive processes in solving variants of computer-based problems used in logic teaching

Sequence effects in solving knowledge-rich problems: The ambiguous role of surface similarities
Sequence effects are said to occur whenever the problem solving performance varies as a function of the order in which problems are solved. We present a framework that explain sequence effects as a result of (a) learning during solving a problem and of (b) transferring the learned content on succeeding problems. In two experiments we studied the ambiguous influence of surface similarities among structurally dissimilar knowledge-rich problems on sequence effects. These experiments demonstrate tha

When less is sometimes more: Optimal learning conditions are required for schema acquisition from mu
While it is usually claimed that multiple examples for the illustration of problem categories are a necessary prerequisite for schema acquisition, there is a lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment – that builds up on a series of studies conducted by Quilici and Mayer (1

Using e-mail to support reflective narration
This article presents an exploratory study of e-mail use for reflective narration. Narration is viewed from three perspectives: the narrating act, the narrative statement, and the story. These perspectives are used to characterize the 69 e-mails that were exchanged between 13 groups of children from three primary schools. The findings show that e-mail narration has monologic and dialogic qualities, and leads to cognitive and personal reflections on the learning task. We conclude that e-mail can

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

Researching classroom interactions: A methodology for teachers and researchers
Teaching and learning in schools is a complex social process which involves both the teacher and students in distributed knowledge-building activities. Research into this process includes researchers exploring from the outside and teachers exploring from the inside (Bassey, 1995). Jaworski (2003) draws on the work of Wagner (1997) to elaborate a form of research which she calls co-learning, in which research on classroom learning is “conducted jointly by outsiders and insiders” (p 250).

Embedded Training for Complex Information Systems
One approach to providing affordable operator training in the workplace is to augment applications with intelligent embedded training systems (ETS). Intelligent embedded training is highly interactive: trainees practice realistic problem-solving tasks on the prime application with guidance and feedback from the training system. This article makes three contributions to the theory and technology of ETS design. First, we describe a framework based on Normanâs "stages of user activity" model for d

The defining characteristics of intelligent tutoring systems research: ITSs care, precisely
his paper argues that, despite the changes in philosophies and techniques that have occurred since ITS research began, there are continuous threads running through this research which define its essential and distinctive nature. In particular, ITSs are computer-based learning systems which attempt to adapt to the needs of learners and are therefore the only such systems which attempt to 'care' about learners in that sense. Also, ITS research is the only part of the general IT and education fie

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 teacher’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.

Learning physics with a computer algebra system
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations with which they are confronted. Still, many students have only a limited representation of the problems on which they are working. Therefore, an instructional approach was devised to promote students' understanding of these problems and to support them in forming associations between problem features and solution methods. The approach was based on using the computer alg

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

The results of the research showed that kindergarten children made considerable progress in their probabilistic thinking,when they accepted th
