Essential Science for Teachers: Life Science: Session 3. Animal Life Cycles
One characteristic of all life forms is a life cyclefrom reproduction in one generation to reproduction in the next. This session introduces life cycles by focusing on continuity of life in the Animal Kingdom. In addition to considering what aspects of life cycles can be observed directly, the underlying role of DNA as the hereditary material is explored.,Students are asked what existed before a bird becomes a bird? Students explain their ideas about eggs and birds. They present interesting a
Détermination automatique des théorèmes-en-acte des élèves en algèbre. Le cas des équations e
Dans cet article, nous sommes intéressés à la détermination automatique de théorèmes-en-acte en algèbre. Ces théorèmes-en-acte ont été construits de façon abstraite, puis nous avons cherché à automatiser le mécanisme de leur diagnostic. Pour cela, nous avons utilisé le logiciel Aplusix comme support des productions des élèves qui permet d'enregistrer toutes les actions des élèves. Une base de règles correctes et erronées a été mise en place et un interpréteur de règles
Book Writing and Wall Writing from the course History of Information
This course explores the history of information and associated technologies, uncovering why we think of ours as 'the information age.' We will select moments in the evolution of production, recording, and storage from the earliest writing systems to the world of Short Message Service (SMS) and blogs. In every instance, we'll be concerned with both what and when and how and why, and we will keep returning to the question of technological determinism: how do technological developments affect socie
Using the World Wide Web to Build Learning Communities in K- 12
Social accounts of learning and human knowledge have led to attempts to reorganize schools as learning communities. This paper examines the utility of World Wide Web (WWW) for aiding in the construction of school-based and work-based learning communities An ordered list of interactions is provided to characterize the depth of students entry into new learning communities. Current offerings on the WWW are then surveyed in terms of these categories. Finally, proposals are advanced for enhancing the

Multimedia and the learner's experience of narrative
This paper reports on research findings which show that the narrative structure of multimedia programs, or sometimes the lack of it, affects learners' comprehension, often adversely [1,2]. It also reports on initial findings from our current research which aims to develop a theoretical understanding of the forms and functions of narrative in interactive media, based on empirical research, and capable of informing instructional design.
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
Competence-based Knowledge Structures for Personalised Learning
The ELeGI project focuses on integrating technology-enhanced learning methodologies into a pedagogy-driven and service-oriented architecture based on Grid technology. It aims at a system that is capable of realising personalised, adaptive, and experiential learning. This requires to have available a framework that, on the one hand, allows for representing existing domain knowledge, and, on the other hand, provides a representation of the learner's current state of knowledge. It is shown that a
Towards Collaborative Learning via Shared Artefacts over the Grid
The Web is the most pervasive collaborative technology in widespread use today; and its use to support eLearning has been highly successful. There are many web-based Virtual Learning Environments such as WebCT, FirstClass, and BlackBoard as well as associated web-based Managed Learning Environments. In the future, the Grid promises to provide an extremely powerful infrastructure allowing both learners and teachers to collaborate in various learning contexts and to share learning materials, lea
