Internet Scout Project
The Evans group at the University of California - Irvine is investigating the unique characteristics of lanthanides and actinide metals. At this website, users can learn about the group's many research projects that generally fall under two categories: redox chemistry and molecules with unusual structure and bonding. The website supplies downloads for many of the publications listed. Students and educators can find general information about lanthanides. Users can learn about the group's exciting
Modélisation formelle en sciences expérimentales : problématiques de la transmission
Cette note de synthèse rédigée en vue de soutenir une habilitation à diriger des recherches (HDR) propose une relecture de mes travaux de recherche sur la modélisation en physique statistique et en écologie comportementale ayant pour but de dégager des problématiques de la modélisation en sciences expérimentales et de les traduire ensuite en problématiques de la transmission. Dans une première partie, je présente mes travaux en me plaçant du point de vue des modèles que jai util
Computer-Supported Collaborative Video Analysis
Video can serve as a powerful medium for analyzing interactions involved in learning activities, for capturing records of teaching for uses in professional development, and for learners to construct or interact with videos expressively, but there have been many barriers to its collaborative uses. The DIVER Project is tackling core problems in advancing computer-supported collaborative video analysis. DIVER establishes a unique video platform for users to control a “virtual camera window” on
Constructivism in the Collaboratory
Great attention has been paid recently to the capabilities of computers to provide environments in which active learners can construct their own understanding through open-ended interaction. Yet discussion of constructivist learning environments has commonly focused on the learner as an individual, learning in isolation from other learners. For example, Perkins (1991) characterizes a learning environment as being composed of five facets: information banks, symbol pads, construction kits, phenome
The Complexity of Distributed Collaborative Learning: Unit of Analysis
The problem area of this paper is manifested in the new conditions that characterise distributed collaborative learning. The core argument is that distributed collaborative learning implies an interconnected complexity that can only be properly understood by extending the unit of analysis from technology and pedagogy themselves to real-life social contexts in which networked computers are being used. Experiments and small-scale field trials are only steps towards a deeper understanding of how co
TELMA Cross Experiment Guidelines
This document contains the guidelines developed by members of TELMA as a means for planning, conducting, and analysing a cross experiment aimed at contributing to the construction of a shared research perspective among TELMA teams . This is the product of the PhD students and young researchers that brought forward the whole activity. The actual experimental phase was proceeded by a reflective phase in which an agreement was achieved on what research questions to address during the experiment. O
EnCOrE (Encyclopédie de Chimie Organique Electronique): an Original Way to Represent and Transfer K
EnCOrE is an original proposal which is expected to allow to share and transfer knowledge in organic chemistry. The system will use MIDES a software, with a peer-to-peer architecture, which will allow to set up a technological and methodological frame to allow collaborative building of knowledge in between chemists. Learning GRID's services will help for Experimental electronic laboratory "LabCOrE" as well as for predictive computational tools.
Theoretical Foundations for E-Learning Environments Direct to Virtual Scientific Experiments
In this work we want to put in evidence the necessity to integrate theoretical, methodological and didactical aspects with innovative e-learning systems, in order to hypothesize possible learning models able to facilitate and qualify the e-learning world. Specifically, our aim will be direct to theoretical learning models of Virtual Scientific Experiments to be implemented inside the platforms. Therefore, the result to be achieved comes from the interaction of two different "macro-environments"

Students learn about the physical force of linear momentum — movement in a straight line — by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological phenomenon of momentum; they see how the “big mo” of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect.

Implementation of ICT in Higher Education as Interacting Activity Systems
Implementation of ICT in higher education is not a trivial process. It is however a process leading to a number of challenges and problems. The paper develops a theoretical model of the implementation of ICT in higher education based on activity theory and on a case study in a Danish university. The model suggest that implementation in itself is an activity system. The implementation activity is composed of three processes: Selection of ICT; adaptation of ICT and change of practice with ICT. Fur
Work and Power: Waterwheel
Investigating a waterwheel illustrates to students the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some period of time. Students create a model waterwheel and use it to calculate the amount of power produced and work done.
A Metadata Based Web Distance Learning Platform
Distance Learning is acquiring a role that becomes more and more important with the huge diffusion of the Internet and related technologies. Consequently, the investigation for adequate architectures and platforms supporting flexible Distance Le arning engines and solution is nowadays of great interests in the Scientific Community. The present paper introduces a platform based on the adoption of Metadata concepts and on the use of a “processorlike” behavior of the Web Course Delivery engine
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.
