Que historia, para qual cidadania? O ensino de historia na educacao basica no Mexico No Mexico a reflexao acerca dos vinculos entre a historia como disciplina escolar e os processos sociais de construcao de cidadania, requer conceber este objeto de estudo como apenas uma parte de um processo muito mais complexo que o vincula tanto a educacao civica e etica, como as praticas cotidianas conformadoras de uma certa cultura escolar. E necessario situar historicamente as origens e formas de funcionamento de cada uma dessas facetas, assim como a maneira em que entre elas se reforcam em suas pretensoes formativas. Somente desse modo e possivel reconhecer os fins, utilidades e limites do ensino de historia tal qual e concebido hoje em dia, assim como sua impossibilidade de assumir como objetivos educativos a construcao de nocoes democraticas referidas a uma concepcao moderna de cidadania. Palavras-chave: Cidadania. Historia e seu ensino. Formacao para a democracia. Resumen En Mexico la reflexion acerca de los vinculos entre la historia como disciplina escolar y los procesos sociales de construccion de ciudadania, requiere concebir este objeto de estudio como solo una parte de un proceso mucho mas complejo que lo vincula tanto a la educacion civica y etica, como a las practicas cotidianas conformadoras de una cierta cultura escolar. Es necesario ubicar historicamente los origenes y formas de funcionamiento de cada una de esas facetas, asi como la manera en que entre ellas se refuerzan en sus afanes formativos. Solo de esa forma es posible reconocer los fines, utilidades y limites de la ensenanza de la historia tal cual es concebida hoy en dia, asi como su imposibilidad de asumir como objetivos educativos la construccion de nociones democraticas referidas a una concepcion moderna de ciudadania. Palabras claves: Ciudadania. Historia y su ensenanza. Formacion para la democracia. Abstract Which history, to which citizens? History teaching in basic education in Mexico In Mexico, a reflection on the links between History as a school subject and the processes of social construction of citizenship requires conceiving the object of study as only part of a much more complex process that binds it both to civic education and ethics, and to everyday forming practices of a certain school culture. It is necessary to historically locate the sources and forms of operation of each of these facets as well as the way they reinforce their training claims.Only in this way it is possible to recognize purposes, uses and limits of teaching History as it is conceived today, as well as its inability to take as an educational goalthe building of democratic notions related to a modern conception of citizenship. Keywords: Citizenship. History and its teaching. Training for democracy.Resumen En este trabajo se evaluan algunos elementos del conocimiento matematico comun y especializado del contenido y del conocimiento del contenido y los estudiantes en relacion con la probabilidad elemental en una muestra de profesores en formacion. El conocimiento comun del contenido se evalua a partir de las soluciones de 157 profesores en formacion a tres problemas. Una vez discutidas con los participantes estas soluciones, se analizan dos componentes del conocimiento de 81 de ellos, trabajando en pequenos grupos: (a) El conocimiento especializado del contenido se evalua a partir de los contenidos matematicos identificados en los problemas; (b) el conocimiento del contenido y los estudiantes a partir de la identificacion y justificacion de respuestas de alumnos de educacion primaria. Aunque en la evaluacion inicial se observo un bajo razonamiento probabilistico, en la segunda los participantes son capaces de identificar y explicar las respuestas incorrectas de los alumnos.

Abstract Normal 0 21 false false false PT-BR X-NONE X-NONE MicrosoftInternetExplorer4 Prospective primary school teachers’ mathematical knowledge for teaching probability: an exploratory study This study assesses some elements of common and specialized mathematical knowledge and of knowledge of content and students in relation to elementary probability from a sample of prospective primary school teachers. Common knowledge of content is assessed from the individual solution of 157 prospective teachers to three problems. Once the solution to these problems was discussed with the participants, two additional components of these teachers’ mathematical knowledge for teaching were analyzed based on small group work developed by 81 participants: (1) To assess specialized knowledge of content we asked participants to identify the tasks mathematical content; (b) to assess their knowledge of content and students we asked them to identify and justify correct and incorrect answers to the problems given by primary school children. While in the initial assessment we observed a poor probabilistic reasoning, in the second part they were able to identify and explain incorrect answers given by students.

Abstract Meaning of knowledge production in Postgraduate studies and its communication with social practices This paper highlights the need, which a Postgraduate Programme in Education may have, of producing knowledge from a continuous effort of integral human experience openness, not closing itself to narrow epistemological positions of that experience. This paper also enphasizes that the education of scholars and education professionals has as main task the consolidation of the intellectual habit of being creative and sensitive towards any manifestation of human life, just as it emerges in various cultural processes, in the diversity and complexity of each one of them and in the reality of social practices that give birth to them.

Conceptions about environment and environmental education: From theory to practice

[Extract] In conditional discrimination choice tasks, one learns to make a choice conditionally based on the presenting discriminative/cue stimulus. Prior research has shown that when each type of correct choice is followed by a cue-unique trial outcome (differential outcomes procedure), learning is faster and more accurate than when a single, common outcome is delivered for all types of correct choice. This learning effect has been termed the differential outcomes effect (DOE). Results are discussed here for brain regions that are active in mediating the DOE, while healthy young adults performed delayed conditional discrimination under event-related functional magnetic resonance imaging (fMRI).Based on two different work motivation theories, the relationships between personality traits (Big Five, CSE: core self-evaluation) and the importance of various job aspects was investigated. In Study I (N=118), graduates with high scores on Openness to experience and Agreeableness placed emphasis on Herzbergs motivation factors, whereas no relations were found for hygiene factors. In Study II (N=117 employees), the Big Five accounted for 30% of the variance in importance of the motivating potential of a job (Job Characteristics Model) and CSE showed incremental validity. Results are discussed regarding person-job fit and the practical utility of the CSE construct.Individual differences in learning nondeterministic relationships were investigated in samples with high mathematical proficiency. Probability Learning tasks were included within selection tests for admission to the French Air Transport Pilot Training. In Study 1 (N=401), two cues had positive and negative relationships with a target criterion. Four classes, homogeneous in mathematical performance, differed in learning the nondeterministic relationships. _ Fast-learners swiftly learned the relationships. _ Medium- and Slow-learners were slower but eventually succeeded. _ Nonlearners (12%) failed to learn even the positive relationship. These patterns replicated in Study 2 (N=448), including a third-irrelevant-cue. The irrelevant cue made the task more complex and degraded more the learning of the negative than the positive cue. Response time analyses confirmed that differences in the learning profiles went along with differences in the decision-making processes.
