Etude de pratiques enseignantes et de différenciations dans les apprentissages mathématiques scolaires à l’école primaire

Dans le cadre du réseau RESEIDA (REcherches sur la Socialisation, l’Enseignement, les Inégalités et les Différenciations dans les Apprentissages, co-piloté par E. Bautier et J-Y. Rochex), je participe depuis plusieurs années à une recherche qui vise à étudier des pratiques enseignantes contextualisées et leurs effets potentiellement différenciateurs sur les apprentissages d’élèves, en croisant des points de vue issus de différentes didactiques et de la sociologie de l'éducation. Dans ce contexte, un imposant corpus de données a été recueilli dans deux classes françaises de CM2 (élèves de 10-11 ans) considérées comme hétérogènes (d'après les résultats d'évaluations nationales, les caractéristiques familiales) en 2004-2005: composé à la fois de données filmiques orientées vers les pratiques d’enseignantes et d’élèves en situation de classe, de photocopies de cahiers ou de productions d’élèves. Ma présentation se centre sur l’analyse d’une partie de ces données, concernant l’enseignement des mathématiques observé dans une des deux classes de CM2. Plus précisément, j’effectue un zoom sur deux situations observées dans cette classe: une situation de résolution de problèmes et une situation d’enseignement des pourcentages. Ces deux situations apparaissent contrastées (gestion enseignante, apprentissages mathématiques potentiels, etc.). Mais elles permettent précisément de montrer que derrière une hétérogénéité apparente de pratiques d’une enseignante, une façon commune de penser et de faire la classe de mathématiques se joue, dont on peut penser qu’elle pèse fortement sur les apprentissages potentiels en contexte scolaire

Ideas previas en el alumnado de magisterio de educación primaria sobre el interior de la tierra

Objetivos del presente estudio: 1) identificar las ideas previas del alumnado de magisterio sobre el estructura interna de la Tierra, con especial énfasis en donde se genera el magma que da lugar a los fenómenos ígneos, tanto volcánicos como plutónicos, y que constituye uno de los eslabones fundamentales del ciclo de las rocas, y, por ende, de la dinámica del planeta en el que vivimos. 2) Plantear posibles estrategias de cara a la enseñanza-aprendizaje de los contenidos relacionados con la estructura interna de la Tierra y con la procedencia/residencia del magma que origina los procesos ígneos

"Enseigner les sciences": un espace numérique d'échange et de formation concernant l'enseignement des sciences à l'école primaire

Cela fait maintenant plus de 10 ans que les premiers dispositifs de e-learning ont vu le jour, que ce soit pour la formation continue ou pour la formation initiale. Dans un premier temps, le recours aux technologies n’a consisté qu’à publier sur Internet l’ensemble des ressources ainsi que le cours, sous forme de texte, dispensé par l’enseignant. Puis, grâce à l’évolution des technologies, de nouvelles possibilités ont vu le jour : la mise en ligne de documents audios, de vidéos, et plus récemment, la mise en place d’espaces numériques de travail permettant à l’enseignant, comme à tous les participants, d’y placer des documents et des commentaires. L’apparition des wikis a permis de voir apparaître de nouvelles formes de e-learning, basés sur la collaboration. Depuis quelques mois, l’explosion des réseaux sociaux, facebook pour le plus célèbre, permet d’envisager de nouveaux dispositifs d’apprentissage interconnectant cours en présentiel et travail à distance

Un Estudio de caso sobre la formación del profesorado de educación primaria en didáctica de la lengua y la literatura

Nuestro trabajo se fundamenta en primera instancia en las investigaciones que tratan y adoptan el conocimiento de los profesores como objeto de estudio y que vienen realizándose desde hace algunas décadas, arrancando de los prestigiosos trabajos de Lee Shulman (1987, 1991, 1992) y su equipo, donde se insiste en la importancia del contenido en la enseñanza y, sobre todo, donde se caracteriza el llamado “conocimiento didáctico del contenido”. Estos estudios han dado lugar a variadas líneas de investigación, impulsadas por autores tan prestigiosos como Grossman (1990), Leinhardt (1992), Clandinin et alii (1992), Connelly y Clandinin (1988), etc., líneas que han intentado conformar una base de conocimiento para la enseñanza centrándose en análisis relacionados con la comparación entre el conocimiento formal y el práctico; el conocimiento informado por los propios profesores; el conocimiento de la materia y su papel en la enseñanza; el conocimiento didáctico, de los aprendices, de los currículos y el didáctico del contenido o los procesos cognitivos de los profesores antes y durante la enseñanza. Se han aportado incluso nuevos lenguajes, como es el caso de los trabajos de Connelly y Clandinin (1985); se han estudiado los componentes usados en la construcción del conocimiento, el conocimiento previo de los docentes, las teorías implícitas de los profesores, el conocimiento práctico personal, las rutinas docentes, imágenes y creencias; se han descrito varios tipos de conocimiento (conocimiento para, en y de la práctica), y se habla últimamente de la adquisición social del conocimiento, proponiéndose “la indagación como actitud” (Cochran-Smith y Lytle, 1999)

Avaluació del projecte Edubosc

L’objectiu principal del Projecte Edubosc és apropar el bosc a l’aula per donar a conèixer a l’alumnat d’educació primària d’entre 8 i 10 anys, la gestió forestal sostenible i la seva importància per als nostres boscos i el seu futur. Per tal d’aconseguir aquest objectiu, el Projecte Edubosc proposa dotze activitats de sensibilització forestal que tracten temes com la multifuncionalitat del bosc, la relació del bosc amb l’aigua, els principals productes del bosc, els oficis vinculats al bosc, la prevenció del risc d’incendis i la titularitat dels boscos. Són temes que els llibres de text no tracten. Aquest treball fa una observació sobre com funcionen les activitats a diverses escoles, a partir dels resultats d’enquestes al professorat i als alumnes. Aquests resultats serviran per proposar alternatives i incorporar noves modificacions al projecte

Solució mental i solució motriu en la iniciació als esports col·lectius en l'Educació Primària

The adjustment of the teaching learning contents in Physical Education, requires of a rigorous analysis that permits to adjust them to the maximum with the educational needs of the student body. It has been approached an investigation study in the one which have intervened pupils, boys and girls, of two different populations, Girona and Madrid in order to prove and analyse the motor and mental components of the student body in the real situation of the game. The hypothesis that we have treated are:if it exists differences between the boys and girls of the educational levels studied in the motor and mental solution in the sports initiation, additionally, the differences that they can exist between the courses and what distance is verified between the study ages to approach a physical activity that implies an initial step to the hour of teaching the collective sports in the classes of Physical education. They have been employed three measure instruments: the first permits to analyse the mental solution without need of practice employing situation photographs of the real game with those which the pupils must choose to who to happen; the second is a pass test that permits to prove the technical dominance to use in a collective sport and the third is a real game situation that permits to put in manifesto the relationship between the mental behaviour and the motor of the pupil. This real game situation is ‘the game of ten pass’ (Blázquez,1986; Torres,1993). The results demonstrate that it do not exist differences between the two sexes in the study ages. In the case of the technical execution level, there is a considerable increase with the age and it is slightly greater in the kids that in the girls. In the case of the real game, we find ourselves with a great variability in the results and we cannot conclude that there are relative differences to the sex in none of the three courses. Respect at participation level during the game is confirmed that the pupils that more participate are not the pupils than more balls lose, what permits to guarantee the idea of the fact that it is convenient to use the real game practice as direct learning element. Finally, there is no a high correlation between the execution level measured in the test of technical execution and the decision execution during the game

Chlorophyll and true-color maps of sediments from the intertidal zones in Winyah Bay, South Carolina, USA and List, Sylt, Germany

We used hyperspectral imaging to study short-term effects of bioturbation by lugworms (Arenicola marina) on the surficial biomass of microphytobenthos (MPB) in permeable marine sediments. Within days to weeks after the addition of a lugworm to a homogenized and recomposed sediment, the average surficial MPB biomass and its spatial heterogeneity were, respectively, 150 - 250% and 280% higher than in sediments without lugworms. The surficial sediment area impacted by a single medium-sized lugworm (~4 g wet weight) over this time-scale was at least 340 cm**2. While sediment reworking was the primary cause of the increased spatial heterogeneity, experiments with lugworm-mimics together with modeling showed that bioadvective porewater transport from depth to the sediment surface, as induced by the lugworm ventilating its burrow, was the main cause of the increased surficial MPB biomass. Although direct measurements of nutrient fluxes are lacking, our present data show that enhanced advective supply of nutrients from deeper sediment layers induced by faunal ventilation is an important mechanism that fuels high primary productivity at the surface of permeable sediments even though these systems are generally characterized by low standing stocks of nutrients and organic material.

The response to an ESL population boom in the Beaufort County, South Carolina school system: A case study

The purpose of this case study was to examine the why the English language learners (ELLs) in the Beaufort County, South Carolina school system have been so successful. This school system has recently experienced a boom in its ESL student population, and this population has performed very well on standardized tests. This study used critical theory as its theoretical framework and examined why the students have been successful rather than marginalized in Beaufort County schools. This phenomenon was investigated using semi-structured interviews with the ESOL Coordinator for Beaufort County, 4 ESL-lead teachers, and 6 mainstream teachers.^ Data were collected using semi-structured interviews with Sarah Owen, the Beaufort County ESOL, Gifted and Talented, and World Languages coordinator. Based on the results of her interview, 4 themes emerged that were used for the semi-structured interviews with ESOL and mainstream teachers. The interviews centered on the themes of ESL policy, ESL leadership, and teacher training. The ESL and mainstream teacher interviews also revealed several subthemes that included teacher attitude, why Beaufort County has been successful with the ELLs, and the teachers' recommendations for other schools systems trying to successfully accommodate a large ESL student population in mainstream classrooms. ^ The findings from the teachers' interviews revealed that additional training for the teachers without ESL experience helped them become comfortable instructing ELLs. This training should be conducted by the ESOL teachers for those without ESOL certification or endorsement. As the teachers had more training, they had better attitudes about teaching ESOL students in their classes. Finally, those who utilized the additional ESOL training and ESOL accommodations saw better student achievement in their classes.^ Based on the finding of this study, the researcher proposed a model for other school systems to follow in order to replicate the success of Beaufort County's ELLs. The implications of this study focus on other schools systems and why ELLs are not obtaining the same level of success as those in Beaufort County's schools. Finally, recommendations for further research are provided.^

Effect of removing user fees on attendance for curative and preventive primary health care services in rural South Africa

User fees are used to recover costs and discourage unnecessary attendance at primary care clinics in many developing countries. In South Africa, user fees for children aged under 6 yea rs and pregnant women were removed in 1994, and in 1997 all user fees at all primary health care clinics were abolished. The intention of these policy changes was to improve access to health services for previously disadvantaged communities. We investigated the impact of these changes on clinic attendance patterns in Hlabisa health district. Average quarterly new registrations and total attendances for preventive services (antenatal care, immunization, growth monitoring) and curative services (treatment of ailments) at a mobile primary health care unit were studied from 1992 to 1998. Regression analysis was undertaken to assess whether trends were statistically significant. There was a sustained increase in new registrations (P = 0.0001) and total attendances (P = 0.0001)for curative services, and a fall in new registrations (P = 0.01) and total attendances for immunization and growth monitoring (P = 0.0002) over the study period. The upturn in demand for curative services started at the time of the first policy change. The decreases in antenatal registrations (P = 0.07) and attendances (P = 0.09) were not statistically significant The number of new registrations for immunization and growth monitoring increased following the first policy change but declined thereafter. We found no evidence that the second policy change influenced underlying trends. The removal of user fees improved access to curative services but this may have happened at the expense of some preventive services. Governments should remain vigilant about the effects of new health policies in order to ensure that objectives are being met.

Integrating environmental education in primary school education in Tanzania : teachers’ perceptions and teaching practices

The study focuses on primary school teachers’ perceptions of environmental education, its integration into primary school education and teachers’ teaching practices in Tanzania. The thesis is based on empirical research. The theoretical underpinnings of the study are based on Palmer’s (1998) model of environmental education. According to the model, meaningful environmental education should include education about, in or through and for the environment. The study is supported by national and international literature from research done on environmental education and education for sustainable development and policy statements. The study is qualitative in nature, adopting phenomenography and phenomenology as points of departure. The empirical data was collected from four primary schools in Morogoro region in Tanzania. The study sample consisted of 31 primary school teachers. Data was collected through interviews and lesson observations. According to the results of the study, primary school teachers expressed variations in their perceptions of environmental education and education for sustainable development. Most of the teachers focused on the aspect of knowledge acquisition. According to Tanzanian education and training policy, environmental education has to be integrated into all subjects. Although there is environmental education in the primary school curriculum, it is not integrated on an equal footing in all subjects. Some subjects like science, social studies and geography have more environmental content than other subjects. Teachers claim that the approach used to integrate environmental education into the school curriculum was not favoured because many claimed that what is to be taught as environmental education in the various subjects is not shown clearly. As a result, many teachers suggested that to ensure that it is taught properly it should be included in the curriculum as an independent subject or as specific topics. The study revealed that teachers’ teaching practices in integrating environmental education varied from one subject to another. Although most of the teachers said that they used participatory methods, lesson observations showed that they limited themselves to question and answer and group discussion. However, the teachers faced a number of barriers in the teaching of environmental education, some of which include lack of teaching and learning resources, time and large class size. The role of teachers in the implementation of environmental education in developing an environmentally literate citizenry is of great significance. The responsibility of the government in developing a curriculum with clear goals and content, developing teachers’ capacity in the teaching of environmental education and provision of teaching and learning materials needs to be taken seriously by the government in educational plans and programs.
