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
Science in Focus: Energy
Explore the notion of "conservation of energy" the idea that energy can neither be created nor destroyed.,Students in an elementary school classroom examine apples that were dried in solar cookers that they made out of aluminum foil and cardboard. They also have tea that was brewed in a jar that sat out in the sun.
The Wellcome Trust Sanger Institute: The Cancer Genome Project
Supported by the Wellcome Trust Sanger Institute, the Cancer Genome Project (CGP) "is using the human genome sequence and high throughput mutation detection techniques to identify somatically acquired sequence variants/mutations and hence identify genes critical in the development of human cancers. This initiative will ultimately provide the paradigm for the detection of germline mutations in non-neoplastic human genetic diseases through genome-wide mutation detection approaches."

Giving teachers a hand(book) to develop ict-enhanced skills
Shared web-based knowledge bases, enriched with the possibilities of discussing about their content and of proposing new one, seem to offer the opportunity to diffuse pedagogical innovation. To this aim, the knowledge base should enable teachers to put their own ideas at colleagues disposal; and moreover, to improve their pedagogical knowledge by availing themselves of colleagues proposals and suggestions. Thus, personal growth evolves in shared knowledge and vice-versa, facilitating the for

Co-Lab: Research and development of an online learning environment for collaborative discovery learn
There are many design challenges which must be addressed in the development of collaborative scientific discovery learning environments. This paper presents an overview of how these challenges were addressed within Co-Lab, a web-based learning environment in which groups of learners can experiment through simulations and remote laboratories, and express acquired understanding in a runnable computer model. Co-Labs architecture is introduced and explicated from the perspective of addressing typi
Towards a Generic Service Oriented Framework for Integrated User Management of Virtual Communities
A central Service layer for the European eLearning Grid Infrastructure (ELeGI) is the one for the management of members and the provision of collaborational services (Virtual Community Services). Because it is a lot of effort to totally newly (re-)write the collaboration services like e.g. a videoconferencing service, it is much more desirable to take existing applications and just to wrap them with a Web Service interface to programmatically access the existing functionality relevant to user m
Students will explore fractions, decimals, percents, and circle graphs with M&M's.
Children's mental models of recursive logo programs
Children who had a year of Logo programming experience were asked to think-aloud about what brief Logo recursive programs will do, and then to predict with a hand-simulation of the programs what the Logo graphics turtle will draw when the program is executed. If discrepancies arose in this last phase, children were asked to explain them. A prevaient but misguided "looping" interpretation of Logo recursion was identified, and this robust mental model persisted even in the face of contradiction be
Observing connections: Art, poetry and the environment
Students will explore the poem of Pat Lowery Collins, "I Am An Artist" and create their own poem from what they see and experience. They will then illustrate their poems with a visual design. This is the first lesson in a series of three in which students are creating art based on their observations: Lesson 1 Observing Connections--Art, Poetry, and the Environment; Lesson 2 Observing Connections--Changing Landscapes; Lesson 3 Observing Connections--North Carolina Pottery and Face Jugs
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
Observing connections: North Carolina pottery and face jugs
This is the third lesson in a series of three in which students are creating art based on their observations: Lesson 1 Observing connections -- art, poetry and the environment; Lesson 2 Observing connections -- changing landscapes; Lesson 3 Observing connections -- North Carolina pottery and face jugs.
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
Teaching Teachers to Use ICT to Teach History: WWF meets ICT in the classroom
In this paper the authors explore the purpose and potential of using ICT to enhance the teaching of some aspects of the history National Curriculum in England and Wales. The focus is on the ways in which learning takes place in the context of historical knowledge and how the appropriate use of computers is able to engage pupils in the process of their own learning. The paper includes many examples and teaching ideas drawn from current classroom practice and training materials for initial teach

Une architecture flexible et extensible
pour l’annotation dans le E-Learning.
Cet article a pour objectif de proposer une architecture flexible et extensible pour l’outil d’annotation MemoNote. Cet outil permet de créer des annotations subjectives et sémantiques sur des documents pédagogiques, tout en étant capable de s’adapter au contexte courant de l’annotateur. Nous définissons les différentes configurations dans lesquelles MemoNote doit pouvoir d’adapter aux changements de contexte. Nous proposons ensuite une architecture pour MemoNote permettant l’a
Semantic annotation for the teacher: models for a computerized memory tool
This article aims to propose a model of semantic annotation dedicated to the teacher. This model must adapt to the teacher’s activity specificity, who needs to master both a pedagogical and domain expertise. In this paper, we analyze the particularity of the teacher’s annotation language that enables the teacher to express his own expertise. First, we identify the concepts of this annotation language used by the community of teachers. Then we propose a conceptual model of this language base
A model for negotiation in teaching-learning dialogues
Despite the fact that a number of researchers from a wide variety of theoretical perspectives have claimed that negotiation in dialogue is fundamental in learning, little research has been based on a precise notion of what negotiation is and how it relates to learning. This paper describes a model for negotiation, based on analysis of teacher-student and learner-learner dialogues. After discussion of illustrative examples and review of related research, negotiations are defined in terms of four
Mind the gap: realising learning across domains
From a number of sources there has developed increasing interest in learning as a lifelong and lifewide process. This has expanded the domains in which learning is now a concern for practitioners and the range of people who might be considered to have an educational role. It has also raised questions about the relationships between learning in these different domains and how to mobilise the full resources of learners within specific sites. This situation poses questions on how best to conceptual
