Un dispositif web pour l'enseignement des mathématiques à l'université : quels impacts sur la per
De nombreuses universités en France ont créé des sites Web pédagogiques avec l'objectif de moderniser leur pédagogie et motiver les étudiants. Les étudiants apprennent-ils mieux avec ces dispositifs ? Sont-ils plus satisfaits et motivés pour apprendre ? Nous avons réalisé une étude expérimentale pour évaluer l'apport pédagogique d'un site Web lors de la réalisation de séances de TD en mathématiques pour les sciences de la vie.

Il y a entre les mathématiques et l'informatique une solidarité fondamentale qui repose sur l'histoire et sur les pratiques actuelles de ces disciplines. Une preuve en est le recours constant aux algorithmes dans les résolutions de problèmes mathématiques fondamentaux et l'existence de l'algorithmique comme domaine constitutif de l'informatique aux côtés d'autres, la théorie des langages, la théorie des automates, etc. Nous présentons[1] ici partiellement les premiers résultats d'un

Rapport de fin de projet de l'ACI : Ecole et Sciences Cognitives - Modélisation cognitive d'élève
Le projet porte sur l'apprentissage de l'algèbre dans un contexte technologique. Le contexte est apporté par le logiciel Aplusix , un micromonde algébrique, réalisé par l'équipe Did@TIC, avec lequel l'élève développe les calculs de son choix, comme dans le contexte papier-crayon, grâce à un éditeur avancé d'expressions algébriques et de raisonnements. En mode « exercice », le logiciel apporte les rétroactions fondamentales : il indique à l'élève si les calculs sont corrects o

Essential Science for Teachers: Life Science: Session 3. Animal Life Cycles
One characteristic of all life forms is a life cycle—from 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

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

Looking at Learning...Again, Part 1: Workshop 8. The International Picture
This workshop offers an opportunity to investigate various aspects of the Third International Mathematics and Science Study (TIMSS), other than the test scores themselves. Distinguished Professor of Educational Psychology William Schmidt presents differences in curricula, textbooks, and teaching practices around the world, and a group of community members discuss how the TIMSS results reflect societal and cultural values.,This segment concerns "tracking" and sets the stage through educator dialo

Knowledge Convergence in Computer-Supported Collaborative Learning: The Role of External Representat
This study investigates how two types of graphical representation tools influence the way in which learners use knowledge resources in two different collaboration conditions. In addition, the study explores the extent to which learners share knowledge with respect to individual outcomes under these different conditions. The study also analyzes the relationship between the use of knowledge resources and different types of knowledge. The type of external representation (content-specific vs. conten

Epistemic and Social Scripts in Computer-Supported Collaborative Learning
Collaborative learning in computer-supported learning environments typically means that learners work on tasks together, discussing their individual perspectives via text-based media or videoconferencing, and consequently acquire knowledge. Collaborative learning, however, is often sub-optimal with respect to how learners work on the concepts that are supposed to be learned and how learners interact with each other. One possibility to improve collaborative learning environments is to conceptuali

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

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

Augmenting the Discourse of Learning with Computer-Based Learning Environments
Computer tools for learning are often thought of as providing practice in working with symbolic representations. We exemplify a different perspective in which the technology augments the kinds of learning conversations that can take place.

Beyond Amplification: Using the Computer to Reorganize Mental Functioning
Computers are classically viewed as amplifiers of cognition. An alternative conceptualization is offered of computer as reorganizer of mental functioning. Software analyses illuminate the advantages of the latter approach for new visions of the potential cognitive benefits of computers. A new result emerges: Because the cognitive technologies we invent serve as instruments of cultural redefinition (shaping who we are by changing, not just amplifying, what we do), defining educational values beco
