Este trabalho de projeto tem como objetivo explorar as possibilidades existentes, no agrupamento vertical de escolas da cidade do Entroncamento, para a conceção de um plano de formação em contexto entre professores do 1.º ciclo e docentes de ciências físicas e naturais do 3.º ciclo/secundário, na área do ensino experimental das ciências. Deste modo, a questão de partida foi: Que plano de formação contínua em contexto é possível promover, num agrupamento vertical de escolas, através de trabalho articulado entre professores do 1.º ciclo e 3.º ciclo/secundário, potenciador de um ensino experimental das ciências? Esta investigação consiste num estudo de caso (Bogdan & Biklen, 2010), de natureza essencialmente qualitativa/interpretativa, baseado na análise dos documentos orientadores do Agrupamento de Escolas Cidade do Entroncamento, em particular no que se refere à articulação vertical dos diferentes níveis e ciclos de escolaridade. Recorreu-se, ainda, a outros instrumentos de recolha de dados, como o levantamento de recursos humanos e físicos em escolas de níveis de ensino distintos, de modo a poder racionalizar e gerir eficientemente esses recursos, e também a um questionário aos docentes da escola básica selecionada, com o propósito de aferir as reais necessidades de formação para o ensino experimental das ciências dos professores do 1.º ciclo. Este projeto evidenciou que é possível implementar um trabalho articulado interpares e interciclos, assente na partilha de saberes e de experiências educativas, sendo uma mais valia o investimento em práticas colaborativas, capazes de valorizar o ensino experimental das ciências. Por outro lado, salientou-se a necessidade de reforçar a capacidade pedagógica dos estabelecimentos de ensino que integram o agrupamento de escolas em estudo e o aproveitamento racional dos seus recursos, para que se possa caminhar no sentido de uma formação contínua contextualizada, que contribua para o desenvolvimento profissional dos professores e consequentemente para uma melhoria dos níveis de literacia científica de todos.

Atualmente, os professores de ciências trabalham com alunos que apresentam sérias dificuldades em duas áreas-chave do ensino: a leitura e a escrita. Esta lacuna, dificulta a aquisição e compreensão de determinados conceitos, o que provoca uma necessidade de melhorar os hábitos de leitura e escrita científica. O estudo apresentado neste trabalho pretende analisar a importância da leitura e escrita científica no ensino das ciências no ensino secundário. Objetiva-se que os alunos aprendam e adquiram práticas de escrita e leitura científicas e ainda que despertem para uma parte da ‘ciência real’, como seja o contacto com os artigos elaborados por investigadores, resultantes de trabalhos de pesquisa levados a efeito em instituições ligadas à investigação científica. Para este efeito desenvolveu-se um estudo com alunos de biologia do 12º ano de escolaridade, durante sete meses, em contexto de sala de aula, no qual foi explorada a leitura de artigos científicos e a elaboração de documentos escritos resultantes de uma análise dos mesmos. Os resultados obtidos demonstram que, de uma forma geral, que os conceitos científicos e conteúdos estudados nas aulas de biologia conforme o programa curricular em vigor, foram, com recurso aos artigos científicos, melhor apreendidos e consolidados. Foi ainda verificado um crescente aperfeiçoamento dos hábitos de escrita e leitura dos alunos. Desta forma, pode afirmar-se que o tipo de estratégia apresentada nesta investigação por via da leitura e da escrita promove a compreensão e a retenção dos conteúdos, ou seja, ler e escrever para aprender.

Leaf-cutting ants consume up to 10% of canopy leaves in the foraging area of their colony and therefore represent a key perturbation in the nutrient cycle of tropical forests. We used a chronosequence of nest sites on Barro, Colorado Island, Panama, to assess the influence of leaf-cutting ants (Atta colombica) on nutrient availability in a neotropical rainforest. Twelve nest sites were sampled, including active nests, recently abandoned nests (<1 year) and long-abandoned nests (>1 year). Waste material discarded by the ants down-slope from the nests contained large concentrations of nitrogen and phosphorus in both total and soluble forms, but decomposed within one year after the nests were abandoned. Despite this, soil under the waste material contained high concentrations of nitrate and ammonium that persisted after the disappearance of the waste, although soluble phosphate returned to background concentrations within one year of nest abandonment. Fine roots were more abundant in soil under waste than control soils up to one year after nest abandonment, but were not significantly different for older sites. In contrast to the waste dumps, soil above the underground nest chambers consistently contained lower nutrient concentrations than control soils, although this was not statistically significant. We conclude that the 'islands of fertility' created by leaf-cutting ants provide a nutritional benefit to nearby plants for less than one year after nest abandonment in the moist tropical environment of Barro Colorado Island.

School absenteeism and particularly unauthorized absenteeism or truancy has been the focus of a number of, so far largely unsuccessful, recent policy initiatives. The paper draws upon two sources of data, the British Household Panel Survey and detailed interviews with a group of persistent truants, to consider the extent, consequences and explanations for truancy from secondary schools. Truancy increases steadily across the years of secondary school and, especially in the later years of compulsory schooling there is evidence that patterns of truancy established in one year carry on into the next. Truancy is strongly associated with negative outcomes in terms of not staying in education post-16, GCSE results and becoming unemployed. Coming from families of low socio-economic status, parents not monitoring homework, negative attitudes towards teachers and the value of education are all associated with higher levels of truancy. However, the majority of young people in these situations do not truant and there are many truants who do not have these characteristics. A major explanation given by young people themselves for their non-attendance is poor relationships with teachers, including teachers failing to match their expectations. Other factors mentioned by young people include bullying but also a more general dislike of the atmosphere of the school, sometimes associated with a change of school. There was little evidence of negative responses to the curriculum leading to truancy. It is suggested that we can distinguish between socio-economic and attitudinal factors which make young people vulnerable to truancy and precipitating events or processes which result in truanting behaviour.

Although the curriculum subject of English is continually reviewed and revised in all English speaking countries, the status of literature is rarely questioned i.e. that it is of high cultural value and all students should be taught about it. The concerns of any review, in any country, are typically about what counts as literature, especially in terms of national heritage and then how much of the curriculum should it occupy. This article reports on three inter-related pieces of research that examine the views of in-service, and pre-service, English teachers about their experiences of teaching literature and their perceptions of its ‘status’ and significance at official level and in the actual classroom; it draws attention to how England compares to some other English speaking countries and draws attention to the need to learn from the negative outcomes of political policy in England. The findings suggest that the nature of engagement with literature for teachers and their students has been distorted by official rhetorics and assessment regimes and that English teachers are deeply concerned to reverse this pattern.

This study explores how children learn the meaning (semantics) and spelling patterns (orthography) of novel words encountered in story context. English-speaking children (N = 88) aged 7 to 8 years read 8 stories and each story contained 1 novel word repeated 4 times. Semantic cues were provided by the story context such that children could infer the meaning of the word (specific context) or the category that the word belonged to (general context). Following story reading, posttests indicated that children showed reliable semantic and orthographic learning. Decoding was the strongest predictor of orthographic learning, indicating that self-teaching via phonological recoding was important for this aspect of word learning. In contrast, oral vocabulary emerged as the strongest predictor of semantic learning.

This article considers the evolution and impact on schools in England of the "Framework for English" since its introduction in 2001, a national initiative that follows on from the National Literacy Strategy, which focused on primary schools. Whilst acknowledging that the Framework is part of a whole school policy, "The Key Stage Three Strategy", I concentrate on its direct impact on the school subject "English" and on standards within that subject. Such a discussion must incorporate some consideration of the rise of "Literacy" as a dominant term and theme in England (and globally) and its challenge to a politically controversial and much contested curriculum area, i.e. "English". If the Framework is considered within the context of the Literacy drive since the mid-1990s then it can be see to be evolving within a much changed policy context and therefore likely to change substantially in the next few years. In a global context England has been regarded for some time as at the extreme edge of standards-driven policy and practice. It is hoped that the story of "English" in England may be salutary to educators from other countries.
