Il ruolo delle nuove tecnologie per superare le difficoltà di apprendimento in aritmetica
Nell’articolo si fa riferimento a varie sperimentazioni che abbiamo realizzato per studiare il ruolo che le tecnologie dell’infromazione e della comunicazione possono svolgere nel superamento delle difficoltà che emergono nell’apprendimento in campo aritmetico e nella soluzione di problemi aritmetici. L’approccio che abbiamo seguito ha come riferimento la teoria della “distributed cognition”, secondo cui la conoscenza è sempre contestualizzata, distribuita negli strumenti, nelle at
Computational Mathetics: Towards a Science of Learning Systems Design
The aim of this report is simply to help put the design of computer-based systems to support learning on a more scientific footing. The aim is simply stated, but its achievement is more difficult. For one thing, it is not at all obvious what "more scientific" means in this context. However, it is essential for AI-ED research to take better account of the concepts of 'situation', 'context', 'community', 'discourse', 'social learning', and so on, but these terms need to be defined, not used as man
Learning with Digital Technologies in Museums, Science Centres and Galleries
As early as 2002 the number of virtual visitors to many museums' websites had already overtaken the number of physical visitors on-site. These developments, both within the walls of the institution and outside them, provide a number of challenges for educators and curators, at the heart of which lie the questions - what is distinctive about learning in museums, science centres and galleries, and how might this change or evolve through the increasing use of digital technologies?,A NESTA Futurelab

Towards Short Term Content Adaptation
Recent works in the E-Learning field tend to focus on the learner, leaving the representation and treatment of contents in the background. One of the principal actors that contribute on this focus shift is the adoption of adaptive techniques that profile learners and adjust the contents according to the inferred profiles. In contrast with most adaptive approaches, this work introduces a short-term adaptive strategy whose aim is to capture the instantaneous interests of users. The proposed model
Designing Assessment Tools in a Service Oriented Architecture
Assessment is an important component of formal learning, and Computer Assisted Assessment (CAA) is a well established component of most online learning. However, technical issues such as interoperability and security, and pedagogic reservations as to its effectiveness still remain barriers to the uptake of CAA. In this paper we examine a number of current assessment projects, predominantly emanating from the UK, to consider how a service oriented architecture can facilitate the implementation o
Towards On-Line Services Based on a Holistic Analysis of Human Activities
Very often computer scientists view computerization of services in terms of the logistics of human-machine interaction, including establishing a contract, accessing records, and of course designing an interface. But this analysis often moves too quickly to tactical details, failing to frame the entire service in human terms, and not recognizing the mutual learning required to define and relate goals, constraints, and the personalized value of available services. In particular, on-line services 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. The mixed distributed learning environme
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. This paper investigates how SCORM can be used in conjunction with learning grids. Aft
Virtual Reality for Learning: Sharing Experiences rather than Resources
Virtual Reality is becoming a major candidate for embodying immersive learning environments. Whereas in the two preceding decades learning has been conceptualized as situations where students are guided rather than elicited to undertake actions, it is now the right time to explore the other side or the continuum.
Open Learning Service Scenarios on GRIDs
The position paper focuses on the concepts of Service Elicitation and Evaluation/Exploitation Scenarios (SEES) and, in particular, on experimental protocols for justifying, motivating, implementing and exploiting Learning GRID's services for very large numbers of potential users.
The Triangle Teacher - Pupil - Knowledge in E-Learning Environment
Our proposal starts from the study of the epistemological statute of the didactics of the mathematics (Henry, 1991; D'Amore, 1999), which faces the phenomenon of learning from the point of view of fundaments, in order to give useful and specific considerations for e-learning environment. In particular we will focus on how the triangle, teacher-pupil-knowledge changes when we use e-learning platforms.
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
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
Literature Review in Science Education and the Role of ICT: Promise, Problems and Future Directions
Today, what "counts" as science and science teaching is in a state of flux. This, however, is not new - for 150 years there have been debates about the purpose, nature and role of science education in our society. Any designer of resources and tools for the teaching of science therefore needs to be able to understand these debates, and to be aware of the origins and reasons for the changes that are currently taking place.,A NESTA Futurelab Research report - report 6
Students' activity in computer supported collaborative problem solving in mathematics
The purpose of this study was to analyse secondary school students' (N=16) computer-supported collaborative mathematical problem solving. The problem addressed in the study was: What kinds of metacognitive processes appear during computer-supported collaborative learning in mathematics? Another aim of the study was to consider the applicability of networked learning in mathematics. The network-based learning environment Knowledge Forum (KF) was used to support students' collaborative problem sol
Analyse de fichiers de traces d'étudiants : aspects didactiques
Users of a learning platforms are usually required to log in, that provides a great deal of data. The general question studied here is: how to exploit this data to help the different actors involved? At first let us introduce the platform and the experiments we conducted. Then we use a didactic model to produce a qualitative analysis from the quantitative data collected. A simple exercise classification emerges from the construction of two indicators. It is consistent with the different experim
Sustaining Interaction in a Mathematical Community of Practice
This paper focuses on an activity in which students explore sequences through a game, using ToonTalk programming and a web-based collaboration system. Our analytical framework combines theory of communities of practice with domain epistemology. We note three factors which influence the length and quality of interactions: facilitation, reciprocation and audience-awareness.
Domain Modelling To Support Educational Web-based
This paper describes an approach to web-based authoring of educational material. We define a model for the class of subjects of our interest (those including both theoretical and practical issues). From this model, specific content outlines can be derived as subclasses and then instanced into actual domains. The last step consists in generating interactive documents, which use the instanced domain. Students can explore these documents through a web browser. Thus, an interactive learning scenario
Combining qualitative evaluation and social network analysis for the study of classroom social inter
Studying and evaluating real experiences that promote active and collaborative learning is a crucial field in CSCL. Major issues that remain unsolved deal with the merging of qualitative and quantitative methods and data, especially in educational settings that involve both physical and computer-supported collaboration. In this paper we present a mixed evaluation method that combines traditional sources of data with computer logs, and integrates quantitative statistics, qualitative data analysis
