O professor coordenador pedagógico nas escolas estaduais paulistas: da articulação pedagógica ao gerenciamento das reformas educacionais

Este artigo apresenta os principais resultados de uma pesquisa concluída que teve como objeto de estudo a função de coordenação pedagógica na rede estadual paulista, com destaque para o trabalho do professor coordenador pedagógico (PCP). A partir de um estudo bibliográfico-documental, analisamos as principais resoluções publicadas pela Secretaria de Estado da Educação de São Paulo no período de 1996 a 2010. Para a definição do período de análise, foram consideradas as sucessivas medidas educacionais de natureza neoliberal ocorridas na referida rede de ensino. A partir das resoluções selecionadas, foram estabelecidas algumas categorias de análise relacionadas à função: denominação, justificativa e atribuições legais; requisitos necessários para os professores coordenadores e critérios de escolha; avaliação do trabalho realizado e bibliografia básica solicitada nos processos seletivos. A análise dos documentos legais permite identificar a apropriação da função pelas reformas educacionais recentes, reconhecendo as implicações para o trabalho docente e para a organização da escola. Influenciadas por princípios gerencialistas e performáticos, as reformas educacionais promoveram profundas alterações na natureza do trabalho do professor coordenador pedagógico, o qual, de articulador no âmbito da escola, passou a ser legalmente o sujeito responsável pela disseminação das medidas oficiais e pelo controle das atividades docentes.

Uma perspectiva da globalização na universidade brasileira

As políticas públicas relacionadas ao ensino superior brasileiro atual vêm estabelecendo seus parâmetros nos moldes da globalização econômica, visando sua inserção no mundo moderno, a partir de um modelo econômico neoliberal assumido como inevitável. As novas formas de organização do trabalho deles decorrentes impuseram um novo tipo de formação, onde o domínio do conhecimento e o tempo de escolarização passaram a ser estratégicos. Porém, a aplicação das recomendações dos órgãos internacionais no Brasil neoliberal privilegia a formação de nível superior fora do sistema universitário público, apontado como atrasado devido aos seus custos, preferindo-se uma outra, onde os critérios de qualidade são os empresariais. As conseqüências são evidentes, acentuando-se o atraso econômico e tecnológico, distanciando-se cada vez mais o país da modernidade.

Atlas escolares municipais: a moda e os professores

Neste artigo abordamos o crescimento das pesquisas e da produção de atlas escolares municipais e a relação entre pesquisadores e professores, considerando o atual contexto curricular e a concepção do trabalho docente segundo a racionalidade técnica que caracteriza as reformas educacionais na sociedade neoliberal. em uma análise dos trabalhos apresentados sobre o tema atlas escolares, nos cinco eventos científicos realizados no Brasil sobre cartografia para crianças, notamos que predomina a produção desses materiais por pesquisadores e especialistas, externa ao âmbito do trabalho dos professores.

A questão do desenvolvimento à luz da globalização da economia capitalista

Cet article cherche à dresser, sous la perspective historique, le bilan de la situation des pays périphériques dans les dernières trentes années. Pour cela, il aborde particulièrement les enjeux du développement dans la phase de la globalisation du capital. Ce travail s'appuie surtout sur les études de la vaste bibliographie publiée récemment. Dans quelle mesure la relance du développement concernant plusieurs secteurs stagnés de la périphérie deviendrait-elle une réelle possibilité? Autour de cette question, que nous trouvons centrale dans l'actuelle conjoncture, nous entamons quelques réflexions. Nous envisageons montrer que la stagnation économique à laquelle des nombreux pays non développés font face ne découle pas en partie d'une crise sociale et économique ouverte dans les années soixante-dix et qui s'élargit jusqu'à nos jours malgré les tentatives de restructuration de la société capitaliste. Les stratégies et les mesures politiques à caractère néo-liberal aussi auraient énormément contribué à cette situation étant donné qu'elles ont renforcé les amarres financières qui ont étranglé pour une part les économies périphériques. Outre ces difficultés, ces pays affronteraient les limites écologiques du capitalisme. La relance du développement dans un nouveau stade exigeant la croissance économique, la justice sociale et la préservation de la nature amènerait à une rupture face au capitalisme.

Semicultura e educação: uma análise crítica da revista Nova Escola

Em suas obras, os filósofos da teoria crítica desenvolveram reflexões muito importantes acerca da sociedade capitalista do pós-guerra, apresentando um potencial pedagógico intrínseco, especialmente por meio dos conceitos adornianos de semicultura e indústria cultural. Este trabalho pretende utilizar tais conceitos para analisar criticamente o conteúdo editorial da revista Nova Escola, da editora Abril. Como esse é um periódico de grande circulação nas escolas públicas brasileiras, essa análise poderá esclarecer a intersecção entre educação e indústria cultural, reflexão que se faz urgente quando consideramos que essa relação atualmente é condicionada pelos imperativos do Estado mínimo neoliberal.

Knowledge Representation and Orthophemism: A Reflection Aiming to a Concept

Characteristics of speech, especially figures of speech, are used by specific communities or domains, and, in this way, reflect their identities through their choice of vocabulary. This topic should be an object of study in the context of knowledge representation once it deals with different contexts of production of documents. This study aims to explore the dimensions of the concepts of euphemism, dysphemism, and orthophemism, focusing on the latter with the goal of extracting a concept which can be included in discussions about subject analysis and indexing. Euphemism is used as an alternative to a non-preferred expression or as an alternative to an offensive attribution-to avoid potential offense taken by the listener or by other persons, for instance, pass away. Dysphemism, on the other hand, is used by speakers to talk about people and things that frustrate and annoy them-their choice of language indicates disapproval and the topic is therefore denigrated, humiliated, or degraded, for instance, kick the bucket. While euphemism tries to make something sound better, dysphemism tries to make something sound worse. Orthophemism (Allan and Burridge 2006) is also used as an alternative to expressions, but it is a preferred, formal, and direct language of expression when representing an object or a situation, for instance, die. This paper suggests that the comprehension and use of such concepts could support the following issues: possible contributions from linguistics and terminology to subject analysis as demonstrated by Talamo et al. (1992); decrease of polysemy and ambiguity of terms used to represent certain topics of documents; and construction and evaluation of indexing languages. The concept of orthophemism can also serves to support associative relationships in the context of subject analysis, indexing, and even information retrieval related to more specific requests.

Thermodynamic analysis of direct steam reforming of ethanol in molten carbonate fuel cell

Fuel cell as MCFC (molten carbonate fuel cell) operate at high temperatures, and due to this issue, cogeneration processes may be performed, sending heat for own process or other purposes as steam generation in an industry. The use of ethanol for this purpose is one of the best options because this is a renewable and less environmentally offensive fuel, and cheaper than oil-derived hydrocarbons (in the case of Brazil). In the same country, because of technical, environmental and economic advantages, the use of ethanol by steam reforming process have been the most investigated process. The objective of this study is to show a thermodynamic analysis of steam reforming of ethanol, to determine the best thermodynamic conditions where are produced the highest volumes of products, making possible a higher production of energy, that is, a most-efficient use of resources. To attain this objective, mass and energy balances are performed. Equilibrium constants and advance degrees are calculated to get the best thermodynamic conditions to attain higher reforming efficiency and, hence, higher electric efficiency, using the Nernst equation. The advance degree of reforming increases when the operation temperature also increases and when the operation pressure decreases. But at atmospheric pressure (1 atm), the advance degree tends to the stability in temperatures above 700°C, that is, the volume of supplemental production of reforming products is very small for the high use of energy resources necessary. Reactants and products of the steam-reforming of ethanol that weren't used may be used for the reforming. The use of non-used ethanol is also suggested for heating of reactants before reforming. The results show the behavior of MCFC. The current density, at same tension, is higher at 700°C than other studied temperatures as 600 and 650°C. This fact occurs due to smaller use of hydrogen at lower temperatures that varies between 46.8 and 58.9% in temperatures between 600 and 700°C. The higher calculated current density is 280 mA/cm 2. The power density increases when the volume of ethanol to be used also increases due to higher production of hydrogen. The highest produced power at 190 mW/cm 2 is 99.8, 109.8 and 113.7 mW/cm2 for 873, 923 and 973K, respectively. The thermodynamic efficiency has the objective to show the connection among operational conditions and energetic factors, which are some parameters that describes a process of internal steam reforming of ethanol.

Physical-chemical and thermodynamic analyses of steam reforming of ethanol to hydrogen production

The steam reforming is one of most utilized process of hydrogen production because of its high production efficiencies and its technological maturity. The use of ethanol for this purpose is a interesting option because this is a renewable and less environmentally offensive fuel. The objective of this study is evaluate the physical-chemical, thermodynamic and environmental analyses of steam reforming of ethanol. whose objective is to produce 0.7 Nm3/h of hydrogen to be used by a PEMFC of l kW. In this physical-chemical analysis, a global reaction of ethanol was considered. That is, the superheated ethanol and steam, at high temperatures, react to produce hydrogen and carbon dioxide. Beyond it's the simplest form to study the steam reforming of ethanol to hydrogen production, it's the case where occurs the highest production of hydrogen (the product to be used by fuel cells) and carbon dioxide, to be eliminated. But this reaction isn't real and depends greatly on the thermodynamic conditions of reforming, technical features of reformer system and catalysts. Other products generally formed (but not investigated in this study) are methane, carbon monoxide, among others. It was observed that the products is commonly produced in the moment when the reaction attains temperatures about 206°C (below this temperature, the reaction trend to the reaetants, that is, from hydrogen and carbon dioxide to steam and ethanol) and the advance degree of this reaction increases when the temperature of reaction also increases and when its pressure decreases. It's suggested reactions at about 600°C or higher. However, when the temperature attains 700°C, the stability of this reaction is occurred, that is, the production of reaction productions attains to the limit, that is the highest possible production. In temperatures above 700°C, the use of energy is very high for produce more products, having higher costs of production that the suggested temperature. The indicated pressure is 1 atm., a value that allows a desirable economy of energy that would also be used for pressurization or depressurization of steam reformer. In exergetic analysis, it's seem that the lower irreversibililies occur when the pressure of reactions are lower. However, the temperature changes don't affect significantly the irreversibilites. Utilizing the obtained results from this analysis, it was concluded that the best thermodynamic conditions for steam reforming of ethanol is the same conditions suggested in the physical-chemical analysis. The exergetic and first law efficiencies are high on the thermodynamie conditions studied.
