Synchronous computer mediated collaborative activities among collocated students: Conditions that ma
Synchronous collaborative activities are usually studied in conditions where teachers and students are physically separated. Is there any possibility to apply these activities when all participants are collocated? Does this collocated collaboration setting seems meaningful and for what reasons? Is the quality of learning and teaching process satisfactory high? Under what conditions? The present research explores the previous questions. More
specifically, it explores synchronous computer mediated
An Algebra Subsystem for Diagnosing Students' Input in a Physics Tutoring System
To help a student in an introductory physics course do quantitative homework problems, an intelligent tutoring system must determine information of an algebraic nature. This paper describes a subsystem which resolves such questions for Andes2. The capabilities of the subsystem would be useful for any ITS which deals with problems involving complex systems of equations. This subsystem is capable of 1) solving the systems of equations at the level of introductory physics problems, 2) checking the
Self-directed learning in simulation-based discovery environments
SIMQUEST1 is an authoring system for designing and creating simulation-based learn-ing environments. The special character of SIMQUEST learning environments is that they include cognitive support for learners which means that they provide learners with support in the discovery process. In SIMQUEST learning environments we try to find the balance between direct guidance of the learning process and sufficient free-dom for learners to regulate the learning process themselves. In this article we de-
The effects of graphical overviews on exploratory behaviour and knowledge acquisition in hypertext e
One of the main and recognized problems of learning with hypertexts is that learners are easily distracted and end up ‘lost in hyperspace’. As a result, they do not acquire complete and adequate knowledge. In this study, we enhanced a hypertext environment with a graphical overview that represented the basic structure of the domain and we designed the layout in such a way that learners were unobtrusively encouraged to follow a sequence of exploration that followed the domain structure. This so
En quoi les TIC changent-elles les pratiques d'ingénierie pédagogique du professeur d'université?
Depuis quelques années, le terme « in-génierie pédagogique » (instructional enginee-ring) est de plus en plus utilisé en rempla-cement de celui de « design pédagogique » (instructional design). Pourquoi? Rappelons d'abord que le terme « design pédagogique » est apparu au cours des années 1960, lors-que certains chercheurs (surtout améri-cains) ont commencé à mettre au point des méthodes systématiques et systémiques de planiï¬cation et de développement de l'en-seignement.

Designing Virtual Learning Centers
Virtual universities and work-place virtual institutes are seen, more and more,
as a solution to the huge education demand of the knowledge society. I will limit my
subject here to the design of Virtual Learning Centers, seen as the pedagogical heart of a
virtual educational institution. This is where courses or learning events are designed,
constructed and delivered using the Internet and its many communication possibilities.
Many models are available for these learning events. High-tech classr
Delivery of Learning Design: the Explor@ SystemÂ’s Case
The IMS Learning Design Specification (IMS-LD) presents new challenges to learning delivery systems. To comply with this specification,
delivery platforms must understand different learning strategies and course structures, must manage multi-actor environments, must allow for standard learning objects integration, must deal with conditions and rules to be validated on runtime and must support notifications.
In this chapter, we take a look at these requirements from the viewpoint of an open deliv
Fostering collaborative knowledge construction with visualization tools
This study investigates to what extent collaborative knowledge construction can be fostered by providing students with visualization tools as structural support.
Thirty-two students of Educational Psychology took part in the study. The students were subdivided into dyads and asked to solve a case problem of their learning domain under one of two conditions: 1) with content-specific visualization 2) with content-unspecific visualization. Results show that by being provided with a content-specific
Computational GRIDs and online laboratories
Many projects addressing the creation of online laboratories have been developed recently. They have a common goal: to enable students and professional learners to get hands-on experience without moving from the places where they are.
Nevertheless, the found solutions are often very different among them, and interoperability between different online laboratories systems does not exist. In this paper we present our work around the exploitation of Grid technologies for sharing instrumentation and

Technology and pedagogy for collaborative problem solving as a context for learning
This workshop, sponsored jointly by CSCW'92 and the Centre for Applied Cognitive Science at the Ontario Institute for Studies in Education (OISE), was organized to bring together researchers with interests in the emerging area of Computer Support for Collaborative Learning (CSCL). It was held at OISE on the weekend preceding CSCW'92 and was attended by 27 participants from academia and industry.
Calculators, graphs, gestures and the production of meaning
In this paper we report an analysis of a teaching sequence in which Grade 11 students were asked to produce some graphs corresponding to the relationship between time and distance of a cylinder moving up and down an inclined plane. The students were also asked to carry out the experience using a TI 83+ graphic calculator equipped with a sensor, and to discuss and explain the differences between their own graphs and the ones obtained with the calculator. We analyze the students' processes of mea

Studying Changes in Learning Environments BroughtAbout by ICT-Based Systems
Aim of our work is to briefly introduce the main aspects of a methodology for the analysis of individuals and environmental changes brought about by the introduction of Information and Communication Technologies (ICT) in learning environments. The theoretical framework underpinning our work is that of Activity Theory. More specifically, we draw on the Cole and Engeström modelling of the complex relationships between elements in an activity. We have worked out our contribution on the basis of th
Lo sviluppo del pensiero strategico nella scuola di base: riflessionisull'uso delle TIC
In recent years the development of skills which are not strictly associated with technical abilities or specific subject contents has become a central focus of education and the debate on how to define and promote what is usually indicated as “core†skills or “key†competencies is involving national educational Institutions and systems, especially in OECD countries.
Among such skills a crucial role is assigned to strategic and reasoning abilities.
While a general agreement on the import
Costruire e gestire ambienti di apprendimento che integrino strumenti tecnologici: analisi di un cas
The paper discusses the results of a research project based on the field testing of a course aimed at developing arithmetic problem solving skills in primary school pupils. The course was designed to incorporate e-learning techniques, including the use of ARI@ITALES authoring tools. These tools allowed the integration in the course of constructivist activities based on interaction with a set of different microworlds. The aims of the project were twofold: to analyse how the adopted approach and t
The Model of Collaborative Learning GRID to activate interactivity for Knowledge Building
The purpose of this study is to support the learning activity in the Internet learning space. In this paper, we examine the GRID technology as the knowledge management for supporting "collaborative learning" / " collaboration in learning" (CL).
RAPSODY-EX (REX) is a distributed learning support environment organized as a learning infrastructure. REX can effectively carry out to support collaborative activities in asynchronous/ synchronous learning mode.

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
