This qualitative nature of work was developed with the participation of a group of students enrolled in the first year of high school from a public school of the state of São Paulo, in the city of Taubaté. Their goal was to determine how students deal with geometry tasks in investigative classes. To guide this research was drawn up the following question: As students of the first year of high school express their knowledge of building triangles and quads in classes of investigative activities?. The choice of investigative nature of this activity occurred by enhancing student participation and thus generate a greater chance of it not be guided only by what the teacher wants, but by his own curiosity and using their own tools for this. In the data analysis process stands out the interest generated in students for this type of activity and posture maintained throughout the work, mobilizing their expertise to answer the questions posed

The theme of the reading in the first year of the literacy cycle has become recurrent in academic papers, research groups, discussion forums, conferences etc. and raised different positions depending on the theoretical framework with which it is studied. While it is granted that reading instruction this school year is to ensure the ability to encode and decode and learn and understand the meanings and the meanings of what we read. In this work, it formed a general objective to investigate how reading skills are being developed in the classroom and the strategies used to develop decoding and understanding of meanings. The question that formed the north to the survey was as follows: The strategies and procedures being used in the teaching of reading in the early literacy process develop the coding and decoding skills beyond the grasp and understanding of the meanings of ideas? The specific objectives were established: a) investigate how is the teaching of reading in the first grade of elementary school; b) identify the teaching strategies and the design of reading and reader that the teacher of the class has observed and relate it to the way he teaches; c) verify that the teaching of reading in the first year of the literacy process, develop the early reading skills, decoding, and favors the development of the apprehension and understanding of the meanings of what we read. The methodology included field research, from a qualitative interpretation approach and had as direct data source the natural environment in which the teaching of reading has been developed. The work then displays data results analyzed in the light of literacy concepts distinguished by Soares (2011), and reading by Silva (1983), Foucambert (1994), Solé (1998), among others. The results were extracted inferences and interpretations. It is hoped that this work raises in literacy teachers, reflections on the teaching of reading in the literacy cicle, in order to establish the...

The theme of the writing learning in childhood education has conquered space in academic works, which occupy in analyze and understand how this process in contexts of meaning and not more before the mechanics of learning letters. Thus, in this work, it constitutes general objective to investigate whether and how the practice of teaching of oral and written expression in the last year of child education promotes the development of the symbol (sign) in children, so necessary to the learning of writing from inside to outside. The questions that served as the North for the study were the following: the teaching of writing, in the last year of child education, is organized to promote the development of the symbol (sign) in children? Which and how the ratings graphics made by children demarcate the stage of development of their writing? For its implementation, a bibliographic research was performed, using as a theoretical support for the prospect of Psychology socio-historical, especially authors as Vygotsky (1984), Luria (2001), Oliveira (1995) and Mello (2005). In addition to this was performed the empirical research of qualitative approach, according to his purpose. The data were collected by six instruments: systematic observation and direct in the classroom; audio-recording; records in a field diary, annual teaching plan of the school; lesson plan weekly and material produced by children, result of write activities. By means of the analysis of these data, we note that the writing has been worked from outside to inside, as an imposition, practice that opposes the theory of Vygotsky, already that the writing has been tackled in a way mechanical, in contexts not significant, with focused practices to the trace of the letters and copy of words, exclusive to the notion of symbol. This result points to the emergence of changes in education of writing in childhood education, without which becomes inglorious the search for a pedagogy of writing aware and...

O aumento da produção agrícola na Amazônia brasileira tem ocorrido devido, em grande parte, à expansão da fronteira agrícola, utilizando áreas já antropizadas ou avançando sobre a vegetação primária. Ao mesmo tempo, os sistemas agrícolas, na pequena produção, continuam utilizando o fogo no preparo da área, o que leva à perda da capacidade produtiva dos solos em curto espaço de tempo, forçando a abertura de novas áreas. Este trabalho avaliou o efeito de métodos de preparo do solo e tempo de pousio que envolvem queima e trituração da vegetação, com permanência na superfície ou incorporada ao solo, com ou sem adubação mineral, em duas épocas do ano sobre os atributos químicos e biológicos do solo. O experimento foi instalado em 1995 em um Latossolo Amarelo do campo experimental da Embrapa Amazônia Oriental, no nordeste do Estado do Pará. O delineamento experimental foi em blocos casualizados, arranjados em esquema fatorial 2 x 6, sendo dois sistemas de manejo e seis tratamentos, estudados em duas épocas de coleta. Os sistemas de manejo envolveram as culturas de arroz (Oriza sativa), seguido de feijão-caupi (Vigna unguiculata) e mandioca (Manihot esculenta). Um sistema constou de dois ciclos de cultivo seguidos, deixando em pousio por três anos; e o outro, de um ciclo de cultivo, deixando em pousio por três anos. Os tratamentos foram: corte e queima da vegetação, com adubação NPK (Q+NPK); corte e queima da vegetação, sem adubação NPK (Q-NPK); corte e trituração da vegetação, deixando-a na superfície do solo, com adubação NPK (C+NPK); corte e trituração da vegetação, deixando-a na superfície do solo, sem adubação NPK (C-NPK); corte e trituração da vegetação, com incorporação e com adubação NPK (I+NPK); e corte e trituração da vegetação, com incorporação e sem adubação NPK (I-NPK). As coletas de solo foram realizadas na estação mais chuvosa (abril de 2006) e na menos chuvosa (setembro de 2006), na profundidade de 0,0-0,1 m. Em cada parcela, foram coletadas 10 amostras simples para compor uma amostra composta. O sistema de manejo mais intensivo apresentou maiores teores de C microbiano (Cmic) e N microbiano (Nmic), ao passo que o sistema menos intensivo mostrou maio teor de C orgânico. Os tratamentos que apresentaram maior teor de Cmic e Nmic foram aqueles em que houve corte, trituração e deposição da biomassa na superfície do solo. Os atributos químicos nos dois sistemas de manejo encontram-se em faixas que enquadram os solos como de baixa fertilidade; no entanto, P e K (no período chuvoso) foram mais elevados no sistema de manejo menos intensivo.
