In this sense, it sought to discuss and analyze the development of argumentative writing with students from public schools. Although the PCN recommend working with a variety of genres since the late 1990s and the school and the textbooks have inserted various genres in the school the student's daily life, not always genres are worked effectively. This research captures the social and communicative functionality of the opinion article by proposing to carry out a systematic work of teaching and learning of writing in the classroom. Given this perspective, we prepared a didactic sequence, based on Dolz theory, Noverraz and Schneuwly (2004), which proposes a set of activities planned around a genre. The pedagogical action was based on Action Research, because we aim to transform the teaching practice and writing of students. To focus on the language skills needed to write the opinion article, we observed the textual production of students in two periods: the first one through skills to be used during the intervention; the second one, in which we examine the appropriation of genre after the application of didactic sequence. The results revealed that after research, the students began to consider the action skills, with the progress in the use of argumentative type and argumentative justification operations, refutation and negotiation. In addition, the results also indicated a greater concern of students with regard to linguistic and discursive skills, such as using modalizers and argumentative operators. Thus, the study reaffirmed the impact of the application of the didactic sequence in the writing of students. / Esta pesquisa trata da a??o pedag?gica do professor no que diz respeito ao ensino da produ??o de textos escritos no 9? ano Ensino Fundamental. Nesse sentido, buscou-se discutir e analisar o desenvolvimento da escrita argumentativa com alunos da escola p?blica. Apesar de os PCN recomendarem o trabalho com uma diversidade de g?neros textuais desde o final da d?cada de 1990 e de a escola e os manuais did?ticos terem inserido diversos g?neros no cotidiano escolar do aluno, nem sempre os g?neros s?o trabalhados de modo efetivo. A presente pesquisa resgata a funcionalidade social e comunicativa do g?nero artigo de opini?o, ao propor a realiza??o de um trabalho sistem?tico de ensino-aprendizagem da escrita do g?nero em sala de aula. Diante dessa perspectiva, elaboramos uma sequ?ncia did?tica, fundamentada na teoria de Dolz, Noverraz e Schneuwly (2004), a qual prop?e um conjunto de atividades planejadas em torno de um g?nero textual. A a??o pedag?gica apoiou-se nos pressupostos da pesquisa-a??o, dado que objetivamos transformar a pr?tica docente e a escrita dos alunos. Tendo como ponto central as capacidades de linguagem necess?rias ? escrita do artigo de opini?o, verificou-se a produ??o textual dos alunos em dois momentos: o primeiro de car?ter investigativo, mediante avalia??o das capacidades a serem abordadas durante a interven??o; o segundo de car?ter avaliativo, em que se verificou a apropria??o do g?nero ap?s a sequ?ncia did?tica. Os resultados revelaram que, ap?s a realiza??o da pesquisa, os alunos passaram a considerar o contexto de produ??o do g?nero, havendo progressos quanto ao uso da tipologia argumentativa e das opera??es argumentativas de justifica??o, refuta??o e negocia??o. Al?m disso, ainda que os alunos n?o tenham se apropriado plenamente da escrita do g?nero, os resultados indicaram tamb?m uma maior preocupa??o dos alunos com rela??o ?s capacidades lingu?stico-discursivas, como o uso de modalizadores e de operadores argumentativos. Sendo assim, o estudo reafirmou o impacto da aplica??o da sequ?ncia did?tica na escrita dos alunos.

The Digital board enables the insertion of didactic-pedagogical objects with historical and cultural themes and the interaction between the students. These materials were elaborated based on a didactic sequence, produced by the teacher-researcher, as proposed by Dolz, Noverraz and Schneuwly (2004), which brings the singularity and popular narratives as the theme of Feira de Santana. In addition, the materials created appear as a stimulus to the local cultural manifestation, their respective insertion in the school routine, the constancy of the rewriting and the prevalence of student protagonism. In order to guide this research, the studies of Ricoeur (2003) and Smolka (2000) regarding the conception of memory have as theoretical background, Hall (2003) and Kellner (2001) in the cultural and identity sphere; the socio-interactionism (IVIC AND COELHO, 2010; VIGOTSKY, 2007); the use of new technologies and Digital board with L?vy (1999) and Nakashima and Amaral (2009); the textual genre Literary Memories with Clara and Altenfelder (2008) and (re) writing with Fiad (1997) and Borges (2016). The methodology used was qualitative, through an intervention proposal (DAMIANI, 2012), in order to demonstrate the students' progress in the textual production of the Literary Memories genre, comparing the initial text with the final text. The intervention took place in the first academic quarter (2017), in weekly meetings. For the production of data, we record in logbook and analysis grid of written productions, in addition to a diagnostic questionnaire and subject scripts. The results of this study point out that the use of multimodal resources contributes, qualitatively, to the teaching-learning process, besides stimulating the student protagonist performance, bringing frequency as one of the variables to advance the knowledge of the subjects. Still, we realize that the diffusion of local history and culture drives discoveries outside the school space, bringing the student closer to his community / Esta disserta??o teve por objetivos aprimorar a leitura e a escrita de Mem?rias Liter?rias, atrav?s da cria??o de materiais educomunicativos, desenvolvidos em atividades sequenciadas na Lousa Digital, no processo ensino-aprendizagem de L?ngua Portuguesa de alunos do 7? ano de uma escola municipal em Feira de Santana (BA). A Lousa Digital possibilita a inser??o de objetos did?tico-pedag?gicos com tem?ticas hist?rico-culturais e a intera??o entre os alunos. Esses materiais foram elaborados com base em uma sequ?ncia did?tica, produzida pela docente-pesquisadora, conforme proposta de Dolz, Noverraz e Schneuwly (2004), a qual traz como mote a cidade de Feira de Santana, suas singularidades e narrativas populares. Al?m disso, os materiais criados aparecem como est?mulo ? manifesta??o cultural feirense, sua respectiva inser??o no cotidiano escolar, a const?ncia da reescrita e a preval?ncia do protagonismo estudantil. Para nortear essa pesquisa, t?m-se como lastro te?rico os estudos de Ricoeur (2003) e Smolka (2000) no que concerne ? concep??o de mem?ria; Hall (2003) e Kellner (2001) no ?mbito cultural e identit?rio; o sociointeracionismo (IVIC E COELHO, 2010; VIGOTSKY, 2007); o uso das novas tecnologias e a Lousa Digital com L?vy (1999) e Nakashima e Amaral (2009); o g?nero textual Mem?rias Liter?rias com Clara e Altenfelder (2008) e a (re)escrita com Fiad (1997) e Borges (2016). A metodologia utilizada foi de abordagem qualitativa, atrav?s de uma proposta de interven??o (DAMIANI, 2012), a fim de demonstrar os avan?os dos alunos na produ??o textual do g?nero Mem?rias Liter?rias, comparando o texto inicial com o texto final. A interven??o ocorreu no primeiro trimestre letivo (2017), em encontros semanais. Para a produ??o de dados, realizamos registro em di?rio de bordo e grade de an?lise das produ??es escritas, al?m de question?rio diagn?stico e escrituras dos sujeitos. Os resultados desse estudo apontam que a utiliza??o de recursos multimodais colabora, qualitativamente, para o processo ensino-aprendizagem, al?m de estimular a performance protagonista estudantil, trazendo a frequ?ncia como uma das vari?veis para o avan?o do Conhecimento dos sujeitos. Ainda, percebemos que a difus?o da hist?ria e cultura local impulsiona descobertas fora do espa?o escolar, aproximando o aluno de sua comunidade

The expected benefits of homogenization include increased mechanical strength, toughness and resistance to delamination. The objective of this study was to evaluate the effect of stacking sequence on the tensile strength of laminates. Composite plates were fabricated using unidirectional layers of carbon/epoxy prepreg with configurations [903/303/-303]S and [90/30/-30]3S. Specimens were subjected to tensile and open hole tension (OHT) tests. According to the experimental results, the mean values of strength for the homogenized laminates [90/30/-30]3S were 140% and 120% greater for tensile and OHT tests, respectively, as compared to laminates with configuration [903/303/-303]S. The increase in tensile strength for more homogenized laminates was associated with the increment in interlaminar interfaces, which requires more energy to produce delamination, and the more complicated crack propagation through plies with different orientations. OHT strength was not affected by the presence of the hole due to the predominance of the interlaminar shear stress in relation to the stress concentration produced by the hole / Laminados formados por l?minas com diferentes orienta??es, finamente dispersas, s?o classificados como homogeneizados. Os benef?cios esperados da homogeneiza??o incluem aumento de resist?ncia mec?nica, da tenacidade e da resist?ncia ? delamina??o. O objetivo deste trabalho foi avaliar o efeito da sequ?ncia de empilhamento na resist?ncia ? tra??o de laminados quase-isotr?picos. Placas de comp?sitos foram fabricadas com l?minas unidirecionais de ep?xi/carbono com configura??es [903/303/-303]S e [90/30/-30]3S. Corpos de prova foram submetidos a ensaios de tra??o e de open hole tension (OHT). De acordo com os resultados experimentais, os valores m?dios de resist?ncia para os laminados mais homogeneizados [90/30/-30]3S foram incrementados em 140% e 120% nos ensaios de resist?ncia ? tra??o e OHT, respectivamente, em rela??o aos laminados com configura??o [903/303/-303]S. O aumento de resist?ncia ? tra??o para laminados mais homogeneizados foi relacionado com o maior n?mero de interfaces interlaminares, que aumenta a quantidade de energia necess?ria para produzir delamina??o, e a maior dificuldade de propaga??o de trincas atrav?s de l?minas com orienta??es diferentes. A resist?ncia medida nos ensaios de OHT n?o foi afetada pela presen?a do furo devido ? predomin?ncia da influ?ncia da tens?o de cisalhamento interlaminar em rela??o ao efeito de concentra??o de tens?o provocado pelo furo

This paper analyzes the Po?o Verde-Cara?bas Fault System, which was initially recognized in subsurface. The activities involved in this study correspond to remote-sensing analysis and, in particular, to the geometric and kinematic analysis of post-rift sequences of the basin. In addition, the study aimed to determine the stress fields operating in the area. The studies were carried out in an area of 1,000 km?, located in the western portion of Potiguar Basin along the Po?o Verde-Cara?bas Fault System, Rio Grande do Norte State. The remote sensing imagery indicates a predominance of NW-SE-trending lineaments, consistent with the fault system under study, followed by the NE-SW, N-S and E-W directions. The tectonic structures mapped were analyzed only in outcrops of the Janda?ra Formantion. They are joints (filled or not) in all directions, but with predominance of the NW-trending joints. Faults are usually N-S-trending normal faults and NW-SE and NE-SW-trending strike-slip faults. Geodynamic analysis identified two tectonic stress fields: the first field, "Field 1" is represented by an N-S-trending horizontal compression and E-W-trending horizontal extension. This field affected the Potiguar Basin at least until the Miocene. The second field, "Field 2", is represented by an E-W-trending horizontal compression and N-S-trending horizontal extension. This is the present-day stress field and has affected the Potiguar basin since the Pliocene / O conhecimento estrutural da por??o oeste da Bacia Potiguar ainda ? incipiente, principalmente aquele relacionado aos sistemas de falhas NW-SE. Esta disserta??o analisa o Sistema de Falhas Po?o Verde-Cara?bas, onde foi inicialmente individualizado em subsuperf?cie. As atividades realizadas inerentes a este estudo correspondem ? an?lise de sensoriamento remoto e principalmente ? an?lise geom?trica e cinem?tica, da seq??ncia p?s-rifte da bacia. Al?m disso, o estudo teve como objetivo determinar os campos de tens?o que operam na ?rea. Os estudos foram realizados numa ?rea de 1.000 km?, localizada na por??o oeste da Bacia Potiguar, ao longo do Sistema de Falhas Po?o Verde-Cara?bas, estado do Rio Grande do Norte. As imagens de sensoriamento remoto indicam uma predomin?ncia de lineamentos orientados na dire??o NW-SE, consistente com o sistema de falha em estudo, seguido das dire??es NE-SW, N-S e E-W. As estruturas tect?nicas mapeadas foram analisadas somente em afloramentos da Forma??o Janda?ra. Eles s?o juntas (preenchidas ou n?o) em todas as dire??es com predomin?ncia para o trend NW-SE. Falhas normais de dire??o aproximada N-S, falhas transcorrentes nas dire??es NW-SE e NE-SW. A an?lise geodin?mica identificou dois campos de tens?es. O primeiro campo, Campo 1 , ? representado por uma compress?o N-S horizontal e distens?o E-W. Este campo atuou na Bacia Potiguar pelo menos at? o Mioceno. O segundo campo, Campo 2 ? representado por uma compress?o horizontal E-W e distens?o horizontal N-S. Este ? o atual campo de tens?es e tem afetado a Bacia Potiguar desde o Plioceno

Com base em referenciais e estudos que tratam das rela??es de g?nero na ci?ncia, quest?es foram levantadas, pesquisadas e discutidas neste trabalho visando promover reflex?es a cerca das consequ?ncias que vis?es distorcidas e ing?nuas podem causar no ensino de ci?ncias. Perante um p?blico participante constitu?do por 91 estudantes e 4 professores do ensino m?dio, realizamos uma pesquisa-a??o no intento de explorar como compreendem ci?ncia e g?nero assim como a rela??o desses campos. Por meio de dois instrumentos de pesquisa, um question?rio e um roteiro de entrevista semiestruturado, as concep??es desses indiv?duos foram coletadas, tratadas e discutidas mediante uso da an?lise de conte?do. Os resultados indicam que quase todos os estudantes e alguns professores compreendem a ci?ncia numa perspectiva neutra, salvacionista, positivista, em que a figura masculina de cientista como protagonista ? predominante. Partindo desse diagn?stico foi constru?da uma sequ?ncia did?tica para o conte?do ?Lei de Conserva??o das Massas? em que buscou-se evidenciar o car?ter cooperativo da atividade cient?fica, mediante a exposi??o da colabora??o de outros cientistas para o estabelecimento dessa lei. O uso da hist?ria da ci?ncia no ensino de qu?mica, e demais ?reas das ci?ncias naturais, pode contribuir para que os estudantes tenham uma compreens?o mais humanizada da cultura cient?fica, possibilitando discuss?es e debates pertinentes ? rela??o ?tica e social. / This dissertation is the result of research conducted with high school teachers and students about their conceptions of gender and nature of science. Based on references and studies dealing with gender relations in science, questions have been raised, researched and discussed in this work, to promote reflections on the possible consequences of distorted and naive visions can cause in science education. In Brazilian educational documents, there are recommendations for addressing the nature of science in high school, present constructivist character, however, which is widespread, both in the discourse of some teachers and in teaching materials is far from what is proposed. It is necessary to promote increased scientific literacy of students - not only understanding and mastery of codes and concepts of science, but the understanding of aspects related to scientific culture. With 91 students and 3 teachers and a high school teacher, we conducted a survey in an attempt to investigate how they understand science and gender as well as the relationship between these fields. Through two research instruments, a questionnaire and a semistructured interview guide, the views of these individuals were collected, treated and discussed by using content analysis. The results indicate that almost all students and some teachers understand science as neutral, Salvationists, positivistic, in which the male figure scientist protagonist is predominant; the students and the teachers, there is no knowledge of women scientists in the history of science; as the reasons for the small number of women in the sciences courses, the public assigns founded justifications mainly in biological determinism and essentialism. Based on this diagnosis, it was built a didactic sequence consisting of 4 classes which sought to highlight the cooperative nature of scientific activity through collaboration exposure of other scientists, including women. For each class has produced a text support making use of the history of science in chemistry education and other areas of the natural sciences. The use of history of science assumes that it can help students to have a more human understanding of scientific culture, enabling discussions and debates relevant to ethics and social relationship. The application of this teaching sequence allowed a better understanding of issues surrounding the nature of science, deconstructing myths that were diagnosed at baseline, as well as allowed the discussion of relevant chemical concepts in this level of education. It is necessary that the school curriculum, through the approach of its contents, provides the training of students for citizenship critically. We need to discuss various social issues such as gender, race, ethnicity, with a view to exploring the diversity, in an attempt to promote new learning.
