Intervenção reflexiva: instrumento de formação continuada do educador especial

O presente artigo busca demonstrar a ocorrência de mudanças na prática pedagógica de uma professora, durante o período em que se fez a reflexão teórico-metodológica sobre essa prática, à luz de proposições da Psicologia sócio-histórica. Foram realizados 20 encontros reflexivos com uma professora da Educação Especial, a partir da análise de gravações das situações ocorridas em sala de aula. As discussões promovidas compreendiam aspectos relacionados ao processo de ensino e de aprendizagem na atividade docente. Foram examinadas as locuções verbais da professora e observaram-se indícios de mudança no que se refere ao foco de atenção, quando ela analisa seus problemas pedagógicos, na consideração da multideterminação dos problemas de ensino e aprendizagem, na concepção de aluno, no método de ensino, no estabelecimento e valorização da relação professor-aluno e da interação de alunos. Os resultados obtidos sinalizaram que a interação reflexiva mostrou-se um instrumento útil para a formação continuada de professores.

Macromolecular properties of cepacian in water and in dimethylsulfoxide

Cepacian is the exopolysaccharide produced by the majority of the so far investigated clinical strains of the Burkholderia cepacia complex. This is a group of nine closely related bacterial species that might cause serious lung infections in cystic fibrosis patients, in some cases leading to death. In this paper the aggregation ability and the conformational properties of cepacian chain were investigated to understand its role in biofilm formation. Viscosity and atomic force microscopy studies in water and in mixed (dimethylsulfoxide/water) solvent indicated the formation of double stranded molecular structures in aqueous solutions. Inter-residue short distances along cepacian chain were investigated by NOE NMR, which showed that two side chains of cepacian were not conformation ally free due to strong interactions with the polymer backbone. These interactions were attributed to hydrogen bonding and contributed to structure rigidity. (c) 2007 Elsevier Ltd. All rights reserved.

Cementum, apical morphology and hypercementosis: a probable adaptive response of the periodontal support tissues and potential orthodontic implications

Information about orthodontic movement of teeth with hypercementosis is scarce. As cementum deposition continues to occur, cementum is expected to change the shape of the root and apex over time, but this has not yet been demonstrated. Nor has it ever been established whether it increases or decreases the prevalence of root resorption during orthodontic treatment. The unique biological function of the interconnected network of cementocytes may play a role in orthodontic movement and its associated root resorptions, but no research has ever been conducted on the topic. Unlike cementum thickness and hypercementosis, root and apex shape has not yet been related to patient age. A study of the precise difference between increased cementum thickness and hypercementosis is warranted. Hypercementosis refers to excessive cementum formation above and beyond the extent necessary to fulfill its normal functions, resulting in abnormal thickening with macroscopic changes in the tooth root, which may require the delivery of forces that are different from conventional mechanics in their intensity, direction and distribution. What are the unique features and specificities involved in moving teeth that present with hypercementosis? Bodily movements would be expected to occur, since inclination might prove difficult to achieve, but would the root resorption index be higher or lower?

Atuação de professores do ensino itinerante face à inclusão de crianças com baixa visão na educação infantil

No momento em que se discute a inclusão de alunos com necessidades educacionais especiais em escolas regulares, faz-se necessário desenvolver trabalhos de pesquisa que se dediquem a analisar as implicações da formação continuada de professores. Neste sentido, estabeleceu-se o objetivo de investigar aspectos relativos às necessidades de duas professoras itinerantes, participantes de um programa de formação. Tal programa, voltado para o acompanhamento de alunos com baixa visão, pretendeu oferecer a essas professoras, sem conhecimentos específicos em deficiência visual, elementos dessa formação, e analisar a natureza das implicações evidenciadas ao longo do processo, do qual foi possível depreender que o desenvolvimento das funções visuais constitui-se em valioso referencial teórico, bem como o fato de estar regularmente na escola, conversar com as professoras, discutir como proceder, avaliar retroativamente os exercícios e ajudar a planejar estratégias com base nas análises feitas foram as principais vantagens de atuar de forma colaborativa.

A formação do professor investigador na escola e as possibilidades da pesquisa colaborativa: um retrato sem retoques

The focus of our research is on how teachers construct their knowledge. We also intend to depth our understanding of the factors that regulate teachers' action - either to maintain, either to modify their professional practice. In order to investigate the means by which teachers learn and the reasons that make them change or resist transforming their practice, we accomplished a task aiming teachers' formation, in a manner similar to a collaborative research design, which involved part of the staff of a school chosen among others which were part of a sample of a previous exploratory study. The subjects were ten teachers of elementary teaching (first stage) and three school administrators. The intervention occurred through our constant presence in the school's daily life, for we believe that empowerment and professional development must be a choice of teachers themselves, based on their own expressed needs toward the construction of their autonomy. A preliminary analysis of data shows that teachers sometimes resist to changes; so these are slow and difficult. Nevertheless, our intervention based on a collaborative research design enabled us to deal with these difficulties, contributing to form a kind of teacher who investigates its own practice.
