Résumé : International audience
This article aims to explore the bilingual practices (English and French) used by students from St Martin in a collaborative situation, in order to enrich the debate on languages and knowledge. This research is based on two corpora consisting of interactions between high school pupils during their educational support sessions, and which are studied using conversational analysis; the study uses this combination of collaborative methods and bilingual education to model the management of linguistic resources with regard to the factual knowledge and practical skills brought into play during the interaction. The challenge of this study is therefore to establish what is involved, and under which conditions and through which mechanisms the interactions between two languages (English and French) may contribute to the construction of cognitive learning skills.

Résumé : International audience
Dans ce travail, nous analysons les données concernant les articles publiés à la conférence EGC. Notre objectif est d’identifier et de comprendre les tendances en matière de collaborations. Pour ce faire, nous adoptons une modélisation descriptive, à travers une approche réseau qui consiste à générer tout d’abord le réseau de collaborations des auteurs à partir des données. Nous enrichissons ensuite les noeuds de ce réseau d’une dizaine d’attributs individuels extraits à partir des données. Enfin, nous recherchons des vues conceptuelles, une approche récente de clustering de liens, qui permet de synthétiser des réseaux en mettant en évidence les ensembles d’attributs retrouvés fréquemment liés dans le réseau. Les résultats obtenus montrent les tendances existantes dans les comportements de collaborations. Dans ce papier, nous présentons ces tendances et montrons comment elles évoluent selon différents seuils d’extraction.

Résumé : International audience
The purpose of this study is to identify links between the geothermal context and the conceptions in different initial teachers training, from the Caribbean and North America. The Caribbean Islands are located in a subduction zone, creating a great potential for geothermal energy. In Guadeloupe, this potential has been harnessed and a geothermal power plant produces about 5% of the local demand for electricity. It is called high temperature geothermy. In Quebec the bedrock mainly consists of ancient Precambrian rocks from the Canadian Shield, which does not allow for electricity production. The geothermal heat is used to regulate the temperature in buildings, to create spars, to grow crops and other purposes. It is called low temperature geothermy. This design-based research (Sandoval, W. et Al., 2004) takes part in the contextualization of sciences education research works (Blanchet, P. et Al., 2009, Anciaux, F. et Al., 2013) and in the continuation of the Gounouy project (Fecil, S. et Al., 2014). A project-based learning on geothermal energy has been set up with two groups of initial teachers training from the Université du Québec à Montréal (UQAM) and from the French West Indies University (UA). The purpose is to create collaborations between each group in order to enable them to encounter, recognize and formulate their conceptions. Further, they will collectively elaborate a more complex understanding of conceptions about geothermy. More specifically, the design used in this experiment aims to highlight context effects (Merlo-Leurette, S., Forissier, T., 2009). Context effects are pedagogical events occurring when there is a clash between the different conceptions of students, observed uring courses regarding different problematics related to geothermal energy. Communications via videoconferences were arranged so that the counterpart teams may discuss their investigative findings. Videos from the exchanges have been collected, as well as weekly summaries about student’s accomplishment, ideas, questions and feelings. Pre-test and post-test questionnaires on geothermal energy were submitted at the beginning and at the end of the project, to compare conceptions before and after the learning process. Collected data enables to bring out the student’s contextuality. Therefore, they highlight context effects, due to the differences between the geothermal contexts in Guadeloupe and in Montreal.This study is supported by the Geotref project.

The objective of this paper is to present an approach for experimenting territorial prospective analysis based on spatial modelling. This approach is carried out in the framework of the DESCARTES project which aims at developing a spatial simulation tool to support the design and analysis of different scenarios for land-use allocation in Reunion Island in terms of environmental services. The spatial modelling tool is composed of two complementary applications: (i) the Ocelet modelling language and its land dynamics simulation environment, and (ii) the Margouill@ platform. The first demonstrator, a model of farm land consumption by urbanization, was developed and presented during workshops in order to test the role of the spatial simulation tool in support of a collaborative innovation process among stakeholders, and to foster new research on social learning, spatial simulation of environmental services, and scale change issues.
L'objectif de cet article est de présenter une démarche de construction d'un exercice de prospective territoriale basé sur un outil de modélisation spatiale. Cette démarche est mise en œuvre dans le cadre du projet ANR DESCARTES dont l'objectif est de construire un outil de simulation cartographique pour analyser différents scénarios d'affectation de l'usage des sols à l'Ile de La Réunion, en termes de services environnementaux. La plateforme de simulation cartographique est composée de deux applications complémentaires (i) le langage de modélisation Ocelet et son environnement de simulation de paysages dynamiques, et (ii) la plateforme Margouill@. Le développement puis la présentation, en atelier, d'un premier démonstrateur sur la consommation des terres agricoles par l'urbanisation a permis de tester l'outil cartographique comme support d'un processus d'innovation collective entre les parties prenantes, et d'ouvrir de nouveaux champs de recherche sur l'analyse de la démarche par les apprentissages, la spatialisation et la simulation prospective des services écosystémiques, et la prise en compte du changement d'échelle.
