Dans cette étude, nous nous sommes intéressé à l’utilisation des TIC, plus précisément du Tableau Numérique Interactif (TNI), en géométrie, par des groupes d’élèves de deux classes du primaire en pédagogie Freinet. S’inspirant d’une revue de littérature concernant la pédagogie dialogique, qui se rapproche de la pédagogie Freinet, trois unités d’observation, qui se rapportent aux trois types de discussion (cumulatif, disputationnel et exploratoire) au sein des groupes, ont été analysées. Le but de l’étude est de comprendre en quoi les discussions des groupes d’élèves autour du TNI, dans un contexte dit dialogique, peuvent être exploratoires (un type de discussion qui favoriserait les apprentissages). Pour cela, une activité d’apprentissage, appelée situation-problème, impliquant six groupes d’élèves autour du TNI, a été créée en collaboration avec les enseignants en géométrie. Nos résultats indiquent, entres autres, que les aspects pédagogiques de la technologie en question, ici le TNI, sont à différencier des aspects pédagogiques du logiciel utilisé, ici Tinkercad en mathématiques. Ce mémoire remet en relief toute la complexité de prendre en compte un unique facteur (l’analyse des discussions) pour discuter des apprentissages des élèves autour du TNI.

A Cultura Digital é uma realidade do século XXI, onde as relações humanas são fortemente mediadas pelas tecnologias e pelo digital. O Digital tem mudado o comportamento das pessoas e influenciado o seu meio cultural. O conceito de Cultura digital inclui saber onde encontrar informação, ferramentas e sistemas, necessários para cumprir uma determinada tarefa de forma não só eficaz, mas também mais eficiente. As competências para explorar as tecnologias que o permitam, são cada vez mais exigidas na interação em sociedade. Tendo em consideração estudos existentes associados com as competências TIC, nomeadamente os propostos pela UNESCO e pelo Executivo Angolano no seu Plano Nacional de Desenvolvimento para 2013-2017, em que está enquadrada a iniciativa da Rede de Mediatecas de Angola, foi tomada a Cultural Digital e a sua promoção no ambito das Mediatecas. Numa primeira avaliação desde da abertura da Mediateca em Fevereiro de 2014, verificamos uma fraca adesão dos professores na utilização dos serviços da Mediateca do Huambo – Angola. Coloca-se neste contexto a questão do porquê que é que os professores não exploram as TIC para as atividades docentes ou da sua aprendizagem? Desta forma, é considerada a questão de investigação: Quais as estratégias a desenvolver para incrementar a exploração das TIC pelos professores e como a Mediateca do Huambo pode servir de espaço para a promoção da Cultura Digital. Foi realizado um estudo de caso, no contexto da Mediateca do Huambo, em que foi efetuada uma recolha de dados pela (a) aplicação de questionários aos professores do 1º e 2º Ciclo do Ensino Secundário do Município do Huambo para mapear as competências TIC dos professores segundo os padrões da UNESCO e o apuramento da formação e uso das TIC em contexto educativo, (b) pela aplicação de um conjunto de tarefas com o objetivo de verificar quais as competências digitais dos professores e por último (c), a implementação do projeto-piloto denominado “ Mediateca +Escola” com o objetivo de levar à Mediateca professores e alunos para desenvolver um projeto TIC onde os professores teriam uma oportunidade de demostrar as competências que afirmavam possuir. Como resultado final obtido neste estudo de caso podemos concluir que 71,27% indicanos que os professores têm a perceção que necessitam de mais formação e desenvolvimento de competências TIC, 27,50% confirma que os professores creem que têm confiança nas TIC. Em face das respostas com valores negativos que apontam para a necessidade de delinear estratégia para capacitar este grupo em competências TIC de forma a incluí-los na sociedade em rede providos de uma Cultura Digital foi proposto o modelo que permite validar os dados obtidos pelo questionário permitindo também delinear estratégias com vista à promoção da Cultura Digital.

This work presents interactions between quantitative and qualitative river freshwater inputs and the shellfish farming (oyster and mussel) in the Pertuis Charentais. The quantity of freshwater (i.e. salinity) seems to have a weak influence on the shellfish farming contrarily to its quality determined by particulate and dissolved matters contained in the water. In autumn and winter, large precipitations have a "globally positive" effect amending the coastal ecosystem. Associated dissolved nutriments and the organic matter largely determine the quality of the coming spring growth for bred shellfish, itself controlling in turn the annual yield efficiencies. However, in winter their effects are postponed because of strong mineral load, low luminosity and temperature, then limiting the primary production. The spring contributions, directly linked to territorial practices, agriculture and tourism are more variable in quantity and quality from one year to another. They often correspond to high-risk inflows since numerous substances from anthropogenic watersheds can be found diluted in the coastal zone as in the Pertuis Charentais. Their impacts on in situ estuarine ecosystems are still poorly known since these substances are mainly studied and estimated in laboratory in controlled conditions. Several studies showed anthropogenic contaminations (i.e. cadmium, pesticides) could have significant direct or indirect effects on shellfish farming. For instance, the "summer" mortalities between 1990 and 2000 in the South of the Marennes-Oléron bay (MOB), that induced environmental and physiological oyster disorders, could be linked to pesticide effects, measured during consecutive years on the oyster bed of Ronce Perquis in the South of the MOB. The weak results from the spring larval rearing of the IFREMER experimental hatchery in the South of the bay, and chromosomal abnormalities measured on the stocks of wild oysters of the Pertuis could confirm a high-risk spring environment for the shellfish farming. In summer terrestrial inputs are reduced by low precipitations, anthropogenic water removals (drinking water, irrigation) and by plant evapotranspiration. Consequently certain years, a significant salinity increase in water masses of the Pertuis Charentais is observed. However, based on long-term observations, the significant interannual variability noticed in freshwater contributions constitutes one of the most important facts of these last years. When contributions are weak (i.e. 1991 and 2011), the mean annual salinity is 34.5 in the MOB. To the contrary, other years (i.e. 1977, 1981, 1983 and 1988), the mean salinity reduced to 30.5 shows the significant freshwater contributions to the bay. Elsewhere, particularly in the mediterranean region, oyster breeding water conditions characterized by high salinity values show the freshwater does not seem to be necessary for biological functions of the Pacific oyster Crassostrea gigas. Indeed, the oyster embryonic life in particular is well adapted to high salinity values as long as trophic resources are substantial and temperatures remain high. These two factors firstly condition the embryonic survival before the water salinity. Besides, in the Pertuis Charentais, wind conditions and the geographical bloodstock position rather determine the success of the larvae capture than seawater physic-chemical conditions. Finally, a misunderstanding still remains on summer freshwater contributions to the oyster larvae food supply.

Digital divide is an issue that concerns our technology dominated society. The parents of ubiquitous computing dreamt of a total proliferation of information technology. But the reality we live in is not yet prepared for this future. There is current a need to develop programs in order to diminish this difference between the digitally included and the excluded one. PROEJA-Transiarte is a project ran by Universidade de Brasília in the city of Ceilândia, Federal District of Brazil. It proposes a different approach on the issue of digital divide, by introducing the cooperative creation of cyberart, based on the life stories of each participant, into the regular curriculum of EJA (Educação de Jovens e Adultos) classes, thus implementing the concept of solidary education. This research project investigated the role played by the cooperative learning the students put in practice during the workshops of the project in the diminishing of the digital exclusion a great part of the students feel. It looked into their activities, analyzing the development of their cooperation, putting it next in the context of the digital and social inclusion. After a multi-dimensional research on the theme, in the context of PROEJA-Transiarte, the conclusion shows the impact cooperative learning has in the reduction of the digital divide, analyzing the perception of the currently involved students, the researchers active in the project, or the former students that had their lives improved because of the workshops they participated in.

Abstract : Information and communication technologies (ICTs, henceforth) have become ubiquitous in our society. The plethora of devices competing with the computer, from iPads to the Interactive whiteboard, just to name a few, has provided teachers and students alike with the ability to communicate and access information with unprecedented accessibility and speed. It is only logical that schools reflect these changes given that their purpose is to prepare students for the future. Surprisingly enough, research indicates that ICT integration into teaching activities is still marginal. Many elementary and secondary schoolteachers are not making effective use of ICTs in their teaching activities as well as in their assessment practices. The purpose of the current study is a) to describe Quebec ESL teachers’ profiles of using ICTs in their daily teaching activities; b) to describe teachers’ ICT integration and assessment practices; and c) to describe teachers’ social representations regarding the utility and relevance of ICT use in their daily teaching activities and assessment practices. In order to attain our objectives, we based our theoretical framework, principally, on the social representations (SR, henceforth) theory and we defined most related constructs which were deemed fundamental to the current thesis. We also collected data from 28 ESL elementary and secondary school teachers working in public and private sectors. The interview guide used to that end included a range of items to elicit teachers’ SR in terms of ICT daily use in teaching activities as well as in assessment practices. In addition, we carried out our data analyses from a textual statistics perspective, a particular mode of content analysis, in order to extract the indicators underlying teachers’ representations of the teachers. The findings suggest that although almost all participants use a wide range of ICT tools in their practices, ICT implementation is seemingly not exploited to its fullest potential and, correspondingly, is likely to produce limited effects on students’ learning. Moreover, none of the interviewees claim that they use ICTs in their assessment practices and they still hold to the traditional paper-based assessment (PBA, henceforth) approach of assessing students’ learning. Teachers’ common discourse reveals a gap between the positive standpoint with regards to ICT integration, on the one hand, and the actual uses of instructional technology, on the other. These results are useful for better understanding the way ESL teachers in Quebec currently view their use of ICTs, particularly for evaluation purposes. In fact, they provide a starting place for reconsidering the implementation of ICTs in elementary and secondary schools. They may also be useful to open up avenues for the development of a future research program in this regard.

Les universités recourent de plus en plus souvent à des plateformes technologiques afin d’administrer les processus éducatifs et faciliter les tâches administratives des étudiants. Cependant, ces changements sont conséquents et engendrent souvent de nombreuses difficultés d’implémentation. C’est dans ce cadre qu’un Observatoire des usages étudiants d’un système éducatif de gestion intégré a été créé. Cet observatoire a pour missions d’identifier les facteurs de satisfaction et de fournir des recommandations à l’université. Plusieurs méthodologies (groupes de discussion, tests d’utilisabilité, questionnaires) ont été utilisées. Les résultats montrent que ce sont les difficultés et insatisfactions dues au système utilisé et aux informations présentes sur ce système qui influencent négativement l’acceptabilité du système. La création d’un tel observatoire permet tout à la fois d’étudier l’acceptabilité et la satisfaction des utilisateurs, de différencier l’impact des facteurs personnels et techniques, de s’interroger sur les processus d’évaluation des outils lors de leur implémentation.

L'utilisation des nouvelles technologies de l'information et de la communication (NTIC) fait l'objet de discussions dans le domaine de l'éducation. La présente recherche a pour objectif principal d'identifier le profil des compétences informatiques et des attitudes du corps professoral d'une haute école de formation technologique du Cambodge au regard de l'utilisation des environnements informatiques dans sa pratique d'enseignement. Cette étude descriptive exploratoire aura comme principale retombée de contribuer au développement de l'intégration des NTIC en pédagogie universitaire au Cambodge. Nous tenterons éventuellement de mettre en lumière les besoins que cette intégration suscite. L'élaboration d'une stratégie de systématisation de l'implantation des NTIC en pédagogie universitaire pourrait être traitée dans une future étude. Le recueil de données a été réalisé à l'aide d'un questionnaire d'enquête ainsi que d'une série d'entrevues réalisées auprès du personnel enseignant de l'Institut de Technologie du Cambodge durant la session d'hiver 2001.

Cette thèse s'inscrit dans un paradigme compréhensif et herméneutique et dans une démarche de recherche qualitative. Elle utilise l'autoethnographie comme méthodologie. L'autoethnographie cherche à comprendre une histoire singulière sociohistoriquement inscrite dans des contextes culturels déterminés L'autoethnographie est à la fois une méthode de recherche, un style d'écriture, une oeuvre et une aventure transformatrice à travers laquelle la chercheure devient le sujet de son histoire. Ici, c'est la vie et l'expérience de la chercheure qui constitue le corpus des données. L'autoethnographie offr une invitation sensible à créer une relation dynamique entre la personne qui raconte son histoire et ses lecteurs. C'est une approche originale, qui fait appel à la vulnérabilité, à la sincérité et à l'authenticité de la chercheure. Le style d'écriture vise à décrire, à montrer et invite à pénétrer la réalité de l'expérience plutôt qu'à théoriser, expliquer ou défendre des certitudes. Cette thèse dévoile la quête transpersonnelle du sujet-chercheure qui traverse une vie d'élève, de mère, d'enseignante, d'étudiante, de formatrice d'adultes et, enfin, d'enseignante en formation initiale à l'enseignement. Une quête vécue dans la culture de l'éducation et qui s'est actualisée à travers des moments clés où se joue, dans et pour la chercheure, une tension entre des approches éducatives centrées sur la personne et son potentiel, et d'autres approches centrées sur les instruments, les contenus et l'évaluation. Cette autoethnographie est présentée sous forme de vignettes qui offrnt au lecteur l'accès à des moments significatifs de vie. La production des données s'est faite à l'aide d'outils variés tels le journal de recherche, le récit de vie, des récits phénoménologiques, des photographies, des poésies, des extraits de travaux d'étudiantes, des documents et des articles. Ces données ont été analysées et interprétées de manière qualitative et en mode écriture en vue de permettre une meilleure compréhension de l'autrice et de sa praxis.

Ce mémoire fait état de la mise en place d'un dispositif d'apprentissage du vocabulaire en contexte, soutenu par les TIC au service du développement de la communication orale en langue seconde (L2) auprès d'élèves et d'enseignants haïtiens. Réalisé dans le cadre de nos études de maîtrise en Sciences de l'éducation à l'Université de Sherbrooke, ce mémoire a permis de répondre à une question souvent traitée sommairement, en ce qui concerne la situation linguistique haïtienne : la communication orale en français, langue seconde. L'animation pédagogique, inspirée de l'approche communicative et de l'approche par compétence, s'est réalisée sous forme de situations d'apprentissage et de micro activités de pratique de l'oral en six étapes. Les données, collectées auprès des participants au moyen d'entrevues semi-dirigées et de présentations orales, permettent d'avancer que le dispositif, tel qu'élaboré, est favorable au développement de la communication orale en français langue seconde des élèves haïtiens.
