Políticas de educação infantil e avaliação

O artigo tem por objetivo apresentar e discutir tensões no debate contemporâneo sobre avaliação na/da educação infantil brasileira, a partir da distinção entre política de avaliação na/da educação infantil e avaliação da política de educação infantil. O texto argumenta que se está iniciando o processo de construção do problema social "avaliação" na arena de negociações da política de educação infantil, daí embates em torno de posições bipolares nos modelos de avaliação propugnados e criticados. Ressalta a importância de cuidados éticos e da explicitação de posições políticas nas pesquisas avaliativas em educação infantil e alerta para o perigo de transpor para a educação infantil modelos hegemônicos adotados no Brasil para outras etapas de ensino.

Incentivos monetários para professores: avaliação, gestão e responsabilização na educação básica

No âmbito da reforma educacional brasileira, o crescente interesse dos governos e legisladores pelas políticas de responsabilização dos professores e das escolas reflete no deslocamento de foco das investigações e pesquisas, que passou da avaliação externa da educação básica à avaliação como mecanismo de gestão educacional por resultados. A presente revisão crítica da literatura visa a situar a polêmica acerca da utilização dos resultados de testes padronizados como instrumentos de gestão educacional e regulação do trabalho escolar por meio dos incentivos monetários por desempenho. O artigo mostra que os discursos dos especialistas oscilam entre dois extremos: de um lado, estão os que criticam tais propostas e buscam investigar os reflexos da reforma política sobre a organização da educação e do ensino; de outro, os que defendem sua implementação como meio de responsabilização dos profissionais e de uma suposta melhoria da qualidade educacional. Entre essas duas posições, há aqueles que demandam mais evidências científicas sobre a efetividade de tais propostas sobre o aprendizado dos alunos.

Educação a distância mediada pela internet: "Linfonodo sentinela, prevenção, diagnóstico precoce e biópsia - nova técnica de abordagem do câncer de mama"

OBJETIVO: O objetivo deste estudo é o desenvolvimento e a aplicação de um curso na modalidade "Educação a distância mediada pela internet". MATERIAIS E MÉTODOS: Foi utilizado o curso "Linfonodo sentinela, prevenção, diagnóstico precoce e biópsia - nova técnica de abordagem do câncer de mama" como modelo de aplicação. O material didático para a modalidade "Educação a distância" foi elaborado visando a um público composto por médicos envolvidos com o tratamento do câncer de mama. O curso foi estruturado em ambiente virtual de aprendizagem, um espaço virtual que permitiu a interação entre os participantes. RESULTADOS: A duração do curso foi de 12 semanas. Iniciou-se com nove participantes, médicos ginecologistas com pelo menos oito anos de experiência profissional. Todos os alunos participaram de alguma forma, dois realizaram exercícios e interagiram. O alcance do curso pelo método atingiu quatro estados e oito municípios. Não ocorreu adesão integral dos alunos, apesar de a maioria permanecer até o fim do curso. Possivelmente, não houve motivação suficiente para participação nas atividades propostas. CONCLUSÃO: Os resultados mostram que é necessário quebrar as barreiras da falta de cultura relacionada a esta forma de aprendizagem. É fundamental a participação facilitadora do coordenador para integração e mobilização dos participantes.

Computadores em educação química: estrutura atômica e tabela periódica

In this paper we discuss an approach for two initial topics in Chemistry: atomic structure and periodic table. The focus of this approach is the use of educational software resources in the perspective of teacher's formation.

História da química e da geologia: Joseph Black e James Hutton como referências para educação em ciências

The second half of eighteenth century is marked by the advancement of chemistry and geology. The first science acquired the law of conservation of mass and this science represented a important support to geology and mineralogy. We say that both became modern science that time. Our aim is to show up some interrelations between history of chemistry and history of geology by means of the study of Joseph Black's and James Hutton's works. We defend that it is positive to science education to understand and approach the relations among different and disciplinary areas of science.

Simulações computacionais e ferramentas de modelização em educação química: uma revisão de literatura publicada

This article presents a review of published literature concerning the use of computer simulations and modeling tools in Chemical Education. The findings about the possibilities of their application in the Chemistry curriculum, their effective implementation, the teaching methods involved, the research methodology and also the instruments of evaluation that were used and their results were described and analyzed. The need to develop adequate theory support to educators who want to start using this new technology in their Chemistry classes became evident along the research, as well as the lack of development of model perception among Chemistry educators and learners.

Educação ambiental na universidade: construindo possibilidades

Environmental education is a big challenge in this century and the University has an important role to play in it. This paper presents a practical experience of environmental education in the university teaching at the University of Bahia. That experience involves the creation of an interdisciplinary group that has been developing research and teaching activities with interdisciplinary perspectives. The paper also discusses a methodology proposed by this group aiming to include environmental education in science teaching using social and cultural approaches.

A química na educação da Princesa Isabel

The private archive of the Brazilian Imperial Family holds a wealth of little known documents about the education of the daughters of Emperor D. Pedro II, especially of the eldest, Isabel, Princess Imperial. Science, particularly chemistry, for which her father had a particular fondness, occupied an important place in the girl's education. The study of these documents sheds a new light on the contrast between female education in the country in general, during most of the 19th century, and the careful upbringing envisaged by the Emperor for his future successor.

Letramento em química, educação planetária e inclusão social

From the different conceptions on scientific and technology literacy (STL), and reflections on globalization and social inclusion, this paper points out the responsibility of the chemists in social actions by their associations for supporting political actions to improving the quality of life, and to protecting the environment by sustainable development for changing the modern society. Supporting ideas for equity within the society between the nations, and giving examples from approaching of socioscientific issues of the textbook "Chemistry and Society", it demonstrated the role of the teachers and the chemistry professionals to realize the STL of the people in the planetary perspective.

Desafios da escola atual: a educação pelo trabalho

This work aims at investigating and proposing strategies to improve the comprehension of Chemistry concepts by high school students. One of these strategies consists in workshops that emphasize the notion of work as a general educational principle, in the perspective of polytechnic education. Interviews (pre and post-workshops) were used to evaluate the results. In post-workshop interviews, a significant incorporation of scientific concepts was observed, as well as a considerable improvement in the interpretation of experiments.

Educação ambiental nas escolas da região de Ribeirão Preto (SP): concepções orientadoras da prática docente e reflexões sobre a formação inicial de professores de química

During short courses, 95 secondary school teachers from 49 state schools and 421 students from the Ribeirão Preto region (in Sao Paulo state, Brazil, with a population of 530,000) were asked to fill in different questionnaires. The points raised in the teacher's questionnaire were used as a guide to establish a continuous dialogue during the short courses. Most of the schools claimed to have some kind of environmental education (EE). Based on the questionnaires and dialogues we analyzed how the teachers' perceptions on EE reflect on the views secondary students hold about their own responsibility for preserving the environment. The role of universities in the preparation of chemistry teachers capable of effectively approaching EE is also discussed.

Considerações sobre o papel da comunicação científica na educação em química

In the present work, we provide some considerations about the role of scientific communication in Chemistry Education. Such considerations may subsidize the development of communication in scientific language by Chemistry students. These considerations are based on information collected during a participatory research for the production of didactic material about scientific communication. The meetings were audio recorded and the contents of the participants' speeches were divided into categories. The category analysis supported the elaboration of the considerations.

Ciência como cultura: paradigmas e implicações epistemológicas na educação científica escolar

"Science as culture" is based on the assumption that science is a valuable component of human culture. We therefore have to build the bridge, in cultural terms, from the scientific community to the common citizen. Teaching science as culture requires the co-construction of knowledge and citizenship. Ways of articulating science/technology with society are invoked, pondering on the ethical ambivalence of such connections. The goals of this reflection are to think about: a) epistemological obstacles that, in favouring the logic of monoculture, oppose the implantation of the science as culture; b) epistemological strategies that point towards a diversity of cultural practices and "constellations" of knowledge leading to the reconfiguration of the being through knowledge; c) imperatives that force us to (re)think the epistemological bases suited to the paradigmatic changes and which translate the dynamics and complexity of the evolution of the frameworks that currently sustain science and school scientific education.

A problematização das atividades experimentais na educação superior em química: uma pesquisa com produções textuais docentes

Through the analysis of articles with proposals for experimental activities and with current pedagogical, epistemological and environmental discussion on experimentation by Chemistry professors, this paper investigates ways of highlighting relevant methodological characteristics that can be incorporated in experiments. Based on analysis of the suggestions for experiments it appears that of particular importance are: a concern for students' physical welfare and for the effects of residues; the need to confront an impoverished infrastructure that hinders experimentation; and the valorisation of clarifying student knowledge. It argues in favour of the need to set out the problems of experimentation in educators' professional development.

O conceito de eletronegatividade na educação básica e no ensino superior

The goal of this study was to examine the means used by textbook authors to introduce, define, and explain the electronegativity concept in high school and introductory college chemistry textbooks. Results obtained showed that most textbooks lacked history precedence and did not deal with the conceptual understanding and manifesting a strong standardization of characteristics that, from our point of view, do not favor the teaching-learning of the electronegativity concept.
