The question that guided this study was: What are the conceptions and survey practices as an educational principle in Science Teaching, in Basic Education in Brazil? Therefore, the general purpose it is to understand the research as an educational principle in the Science Teaching in Basic Education in Brazilian contexts. This is a theoretical study with a qualitative approach, whose survey?s method consists in a Literature Systematic Review (LSR). The work consisted in the identification of Brazilian PhDs researchers, with at least two productions, in the period from 2000 to 2015. The key-words, in addition, should mention the expression " Sciences teaching ", referring also expressions such as: "educating by the research", "survey in the classroom", "investigation in the classroom", "teaching by survey", "research in school", "education through research," "classroom with research," "investigative classes", " investigative class ", "teaching by investigation" and "learning by survey". Therefore, it was found 88 researchers from several regions of the country, with the exception of the North Region. The production of these researchers related to the theme, in this period, formed the analysis? corpus, consisting qualified articles (Qualis/CAPES), books and book chapters and complete works in relevant events. The LSR of this corpus, plentifully detailed in the work, conducted, mainly, the two main conceptions of research as an educational principle in the context of the teaching of the Sciences, focused on the Basic Education, but may also extend to the Higher Education and in other areas: educating for research/survey in the classroom and teaching by investigation. These conceptions were characterized in order to clarify its vicinity and estrangements. / Esta investiga??o apresenta as principais concep??es e pr?ticas de pesquisa como princ?pio educativo no ensino de Ci?ncias na Educa??o B?sica em contextos brasileiros. A quest?o que guiou esta investiga??o foi: Quais as concep??es e pr?ticas de pesquisa como princ?pio educativo no ensino de Ci?ncias na Educa??o B?sica no Brasil? Desse modo, o objetivo geral ? compreender a pesquisa como princ?pio educativo no ensino de Ci?ncias na Educa??o B?sica em contextos brasileiros. Trata-se de um estudo te?rico, com abordagem qualitativa, cujo m?todo de pesquisa consiste na Revis?o Sistem?tica de Literatura (RSL). O trabalho consistiu na identifica??o de pesquisadores doutores brasileiros, com pelo menos duas produ??es, no per?odo de 2000 a 2015, cujas palavras-chave, al?m de referir a express?o ?ensino de Ci?ncias?, referissem tamb?m express?es como: ?educar pela pesquisa?, ?pesquisa em sala de aula?, ?investiga??o na sala de aula?, ?ensino pela pesquisa?, ?investiga??o na escola?, ?educa??o pela pesquisa?, ?sala de aula com pesquisa?, ?aulas investigativas?, ?aula investigativa?, ?ensino por investiga??o? e ?aprendizagem por investiga??o?. Desse modo, chegou-se a 88 pesquisadores das v?rias regi?es do pa?s, com exce??o da Regi?o Norte. A produ??o desses pesquisadores relativas ao tema, nesse per?odo, formou o corpus de an?lise, constitu?do de artigos qualificados (Qualis/Capes), livros e cap?tulos de livros e trabalhos completos em eventos relevantes. A RSL desse corpus, fartamente detalhada no trabalho, conduziu, principalmente, a duas concep??es principais de pesquisa como princ?pio educativo no ?mbito do ensino de Ci?ncias, voltada ? Educa??o B?sica, mas podendo tamb?m se estender ao Ensino Superior e em outras ?reas: o educar pela pesquisa/pesquisa em sala de aula e o ensino por investiga??o. Essas concep??es foram caracterizadas de modo a explicitar suas proximidades e distanciamentos.

The expansion on debates seen on the mass Communication Systems about Penal Process has made it to become popular, the desire for punishment and reprimand has been taking up more space on the communication vehicles and on the criminal process pages, which demands that our democratic structure is followed more than never and this also requires that the constitutional reform to the penal process is not put off anymore. As a new approach to comprehend the process situation is developed, we should also evaluate the judge's role. It is undeniable the power given to whom is judging, which has clear importance to any reform to the penal process. That defines judge's role in a penal process, thereafter to analyze the judge, his influences, his subjectvities and the way it can affect the judgment we will have for this country. It is a must to shift the problem to the preliminary investigation as this is the moment when individual guarantees established constitutionally are less observed although it is when proofs that will influence the judge the most are produced , Therefore preliminary investigation has to be modified to fit to what is defined on the constitution, which also results in modifications to judge's role. This it is time to accept the new, to recognize the problem and take on the fact that we must not put off a reform that will give a new shape to the constitution, that will ensure to persons the respect to their rights. Taking that into consideration the guarantee judge becomes an extreme relevant role, that will be at least an agent to reduce the damage that is seen in penal process currently, in how we conceive the judge and treat the preliminary investigation phase / Hodiernamente, trava-se uma ferrenha luta em nosso processo penal, dada a expans?o dos debates, representadas pela ocupa??o cada vez maior de assuntos relacionados com o tema na m?dia, o processo se popularizou. E, com isto, anseios punitivistas e repressivos passaram a cada vez mais ocupar a m?dia e as folhas dos processos criminais. Da? a necessidade de fazer valer a garantia de nossa estrutura??o democr?tica de Estado, da? a necessidade de n?o mais poder se adiar uma reforma constitucional de nosso processo. Ao necessitarmos de uma reforma, de uma nova forma de compreender a situa??o processual, devemos avaliar, sempre a atua??o do julgador frente ? este. Ineg?vel o poder concedido ao juiz, o que torna evidente a sua relev?ncia para qualquer reforma que se pretenda no processo penal. Com isto, se define a atua??o do julgador em um processo penal constitucional e, a partir da?, se analisa o julgador em si, suas influ?ncias, suas subjetividades e a forma como estas podem influenciar num julgamento que teremos e no processo que queremos para o nosso pa?s. Para isto, imprescind?vel o deslocamento do problema para a fase de investiga??o preliminar, por ser este o momento em que as garantias individuais, previstas constitucionalmente, s?o mais vilipendiadas e, paradoxalmente, ? o momento onde se produzem as provas que mais influenciam no convencimento do julgador. Por isto, deve-se adequar a investiga??o preliminar aos ditames constitucionais, o que exige uma adequa??o do papel do julgador ? este.Sendo assim, ? hora de aceitar o novo, de reconhecer o problema e assumir que n?o mais podemos adiar uma reforma que venha a dar ao nosso processo penal uma roupagem constitucional, que assegure aos indiv?duos o respeito ? jurisdicionalidade e todas as suas vincula??es. E quanto ? isto, o juiz de garantias se apresenta como um elemento de extrema relev?ncia, que vir? a ser, no m?nimo, um redutor dos danos que hoje verificamos em nosso processo penal, na forma como concebemos o julgador e tratamos da fase de investiga??o preliminar

Problemas de instabilidade envolvendo estas estruturas trazem consequ?ncias catastr?ficas ? sociedade. A barragem do A?u, ? uma obra geot?cnica de significativa notoriedade e import?ncia no Nordeste, principalmente no estado do Rio Grande do Norte. ? a maior barragem do estado e ganhou destaque na literatura nacional e internacional com o rompimento do talude de montante no final do per?odo construtivo. Em casos de ruptura, a retroan?lise ? uma t?cnica confi?vel para determina??o dos par?metros de resist?ncia ao cisalhamento dos solos de forma a contribuir para que se evite casos semelhantes. A partir da avalia??o de dados de resist?ncia dispon?veis no meio acad?mico, este trabalho teve como objetivo retroanalisar a ruptura ocorrida para obter os par?metros m?dios de resist?ncia ao cisalhamento do material argiloso preto que constitu?a o n?cleo da barragem do A?u antes do acidente ocorrido. Na primeira etapa do trabalho foram realizadas an?lises de estabilidade do talude de montante da barragem e na segunda etapa a retroan?lise determin?stica e probabil?stica. Essas an?lises foram realizadas no software Slide 7.0 pertencente ? plataforma RocScience. Os resultados mostraram que o talude romperia com os par?metros de resist?ncia da argila siltosa preta na condi??o saturada, com valores de probabilidade de ruptura variando de 60 a 97% entre os m?todos de equil?brio limite utilizados nas an?lises. Tamb?m foi poss?vel definir os poss?veis par?metros m?dios de resist?ncia ao cisalhamento da argila siltosa preta e estabelecer as causas de ruptura da barragem. Os valores da coes?o e do ?ngulo de atrito, no instante de ruptura, obtidos na retroan?lise determin?stica para a argila siltosa preta foram cu=47,1 kPa e ?u=0?. Na retroan?lise probabil?stica os valores da coes?o e do ?ngulo de atrito obtidos foram cu=33,8 kPa e ?u=3,1?, com uma probabilidade de ruptura de 52,7%. Com isso, conclui-se que a ruptura do talude de montante da barragem do A?u ocorreu por causa de erros na fase de projeto e de constru??o da barragem acompanhado pela perda de resist?ncia do solo devido aos excessos de poropress?es gerados durante a constru??o. / Risks associated to dam failure are very high. Problems of instability involving these structures bring catastrophic consequences to the social comunity. The A?u dam is a geotechnical work with significant importance in the Northeast, mainly in Rio Grande do Norte state. It is the largest dam of the state and has gained prominence in national and international literature with the slice of the upstream slope at the end of its construction period. In cases of failure, back analysis is a reliable technique used to calculate the shear strength parameters of the soil in order to avoid similar cases to happen. Considering the evaluation of strength data available in the academic environment, this work had as purpose to analyze the failure occurred in order to obtain the average shear strength parameters of the black clayey material that constituted the A?u dam core before the accident. In the first stage of this work the slope stability of the dam was analyzed and in the second stage the deterministic and probabilistic back analysis was performed. These analyzes were performed in Slide 7.0 from Rocscience platform. The results showed that the slope would fail with strength parameters of the black silty clay in the saturated condition, with values of probability of failure ranging from 60 to 97% between the equilibrium limit methods used in the analyzes. It was also possible to define the possible average shear strength values of black silty clay and to establish the causes of the dam failure. The cohesion and the friction angle values obtained at the instant of failure in the deterministic back analysis for black silty clay were cu=47.1 kPa and ?u=0?. For the probabilistic back analysis the cohesion and the friction angle values obtained were cu=33,8 kPa and ?u=3,1?, with a probability of failure of 52,7%. Therefore, it is concluded that the A?u dam upstream slope failure occurred because of errors in the design and construction phase of the dam accompanied by the loss of soil strength due to the excess of poropressures generated during the construction.

In this sense, the undertaken research involved the teachers, the main representatives and experts in that cultural tradition, in order to investigate how the everyday activities (agriculture, food handling, assets distribution among the community members, etc.) and the cultural tradition (log race, body painting, clan division, Xerente numeration, Indian myths and histories, etc.), may enable the contextualization of the mathematics teaching in the lndian School Sr?mt?w? of this hamlet, under a more transversal and globalizing perspective of the local and school knowledge. We based this research in the sociocultural conceptions of knowledge generation proposed by D Ambrosio (1990; 2002); Vergani (2007); Oliveras (1996); Gerdes (1991; 2002); Bishop (1999) e Sebastiani Ferreira (1997; 2004). ln the process of this study we propose some viable ways so that the Indian teachers may reorganize their classroom knowledge and actions, based in the strengthening of their history and culture. The observation of some social practices and knowledge as well as of the Xerente traditions helped us to point some possibilities of projection of a didacticalpedagogical dimension of these activities and practices, in the development of the school mathematical knowledge in this community / A partir da investiga??o, an?lise, discuss?o e reflex?o acerca das atividades desenvolvidas pelos ind?genas da aldeia Porteira, da comunidade Xerente, no estado do Tocantins, desenvolvemos um estudo investigat?rio e descritivo da realidade desse povo, visando colaborar na forma??o conceitual e na reorienta??o da pr?tica pedag?gica dos professores locais. Neste sentido, a pesquisa realizada envolveu professores, principais representantes e conhecedores daquela tradi??o cultural, de modo a verificar de que maneira as atividades cotidianas (agricultura, manuseio dos alimentos, distribui??o de bens entre os membros da comunidade, etc...) e a tradi??o cultural (corrida de tora, pintura corporal, parti??o cl?nica, numera??o Xerente, hist?rias e mitos ind?genas, etc...), podem favorecer a contextualiza??o do ensino da matem?tica na Escola Ind?gena Sr?mt?w? desta aldeia, sob uma perspectiva mais transversal e globalizante do saber local e escolar. Ao desenvolvermos essa pesquisa nos apoiamos nas concep??es socioculturais de gera??o de conhecimento propostas por D Ambrosio (1990; 2002); Vergani (2007); Oliveras (1996); Gerdes (1991; 2002); Bishop (1999) e Sebastiani Ferreira (1997; 2004). No decorrer do estudo esbo?amos alguns caminhos vi?veis para que os professores ind?genas possam reorganizar seus saberes e fazeres de sala de aula, com base na valoriza??o da sua hist?ria e cultura. A verifica??o de algumas pr?ticas e saberes sociais bem como das tradi??es Xerente contribuiu para apontarmos algumas possibilidades de proje??o de uma dimens?o did?tico-pedag?gica dessas atividades e pr?ticas, no desenvolvimento do conhecimento matem?tico escolar, nesta comunidade

The investigation was developed with two teachers from the first years of the Elementary School, from a public school in Pau dos Ferros-RN. It adopts as basis the notion of knowledge as a set of individual and social relations that the individuals maintain with the world and with themselves, in the teaching and learning relation. (CHARLOT, 2000). It considers yet that the knowledges are immediate processes, reconstructed and mobilized by the practice of reflection, in dialogical and interactional contexts in contact with others. (BAKHTIN, 2002, 2003; VYGOTSKY, 1991, 2004, 2005). The collaborative approach was the theoretical and methodological background that oriented the investigative-educative process. By choosing a collaborative research as basis of the investigative pathway, it starts from the knowledge that the critical and collaborative reflection developed with the teachers from the first years of the Elementary School contribute to explicitate and resignify the meanings assigned to the knowledges that these teachers mobilize in the organization of the teaching-learning and its implications in this process. The results of the reflexive and investigative process developed with the teachers demonstrate that the familiar, scholastic, academic, professional, and the work knowledges lived, constitute the consciousness of being a teacher, and that these knowledges implicate in the dynamics of the process of teaching-learning, but not always the teachers take consciousness about these knowledges. The critical and collaborative reflection, mediated by the actions of describing, announcing, facing and reconstructing allowed to the participants of the research to realize the knowledges of themselves and of the other, the difficulties and possibilities in the organization of the teaching-learning process / O presente estudo tem como objetivo analisar com professoras do ensino fundamental os saberes mobilizados na organiza??o do processo de ensino-aprendizagem e suas implica??es na dinamiza??o desse processo. A investiga??o foi desenvolvida com duas professoras dos anos iniciais do ensino fundamental de uma escola p?blica do munic?pio de Pau dos Ferros-RN. Adota como fundamento a no??o de saber como um conjunto de rela??es individuais e sociais que os sujeitos mant?m com o mundo e consigo mesmo, na rela??o com o ensinar e o aprender. (CHARLOT, 2000). Considera, ainda, que tais saberes s?o processos mediados, (re)constru?dos e mobilizados pelo exerc?cio da reflex?o, em contextos dial?gicos e interacionais na rela??o com o outro. (BAKHTIN, 2002, 2003; VYGOTSKY, 1991, 2004, 2005). A abordagem colaborativa foi o referencial te?rico-metodol?gico que orientou o processo de investiga??o-forma??o. Ao escolher a investiga??o colaborativa como orienta??o do caminho investigativo, parte do pressuposto de que a reflex?o cr?tica e colaborativa desenvolvida com as professoras dos anos iniciais do ensino fundamental contribui para explicitar e ressignificar os sentidos atribu?dos aos saberes que estas mobilizam na organiza??o do ensino-aprendizagem e suas implica??es nesse processo. Os resultados do processo investigativo e reflexivo desenvolvido com as professoras demonstram que os saberes da trajet?ria familiar, escolar, acad?mica, profissional e do trabalho vivido constituem o saber-ser docente, e que esses saberes implicam-se na din?mica do processo de ensinar-aprender, mas nem sempre as professoras tomam consci?ncia deles. A reflex?o cr?tica e colaborativa, mediada pelas a??es do descrever, informar, confrontar e reconstruir, oportunizou ?s part?cipes da pesquisa a percep??o dos saberes de si e do outro, das dificuldades e das possibilidades na organiza??o do processo de ensino-aprendizagem

Therefore, this research has as an objective to contribute with Science teacher continuing formation in the basic education, in the use of the investigative approach, with a view to overcoming obstacles and making change in pedagogical practice using this research elements. For this, a qualitative research with science teachers of basic schools in the city of Natal/ RN/ Brazil was held, who attended the training course on teaching by investigation in 2012, through the project entitled "Em Busca de Novos Talentos para a Ci?ncia: uma interven??o no ensino p?blico" (Searching New Talents for Science: an intervention in public education).The research was conducted in four stages: Diagnosis of the conceptions of education for research and incorporation into practice after the New Talents course; projection of the intervention, intervention and evaluation. To obtain the data it was made a questionnaire, semi-structured interviews, group studies, written records and participant observation. It was analyzed that the course had significant contributions to the participating teachers to promote the approach and the motivation for incorporation of the investigative approach in practice. The permanence of weaknesses related to the theoretical basis was found, the wear resistance, difficulty in planning activities and the change in practice, diagnosed the previous course of this research. It was also noticed certain lack of domain of teaching principles of investigation by the teachers, who despite being well understood in theory, reveal gaps in practice. Despite not having been exploited the full potential of investigative activity is apparent that the inclusion of activities with an investigative approach to science and biology classes is essential for an active, critical and reflective posture of the students as well as the interest in learning about science. It was demonstrated that intervention with moments of reflection, engagement, knowledge exchange, it was effective in overcoming difficulties identified at baseline as well as providing greater motivation to face the innovations and changes in education, suggesting an important format to considered in the course of continuing education. This is because the planning and replanning allow teachers to reflect and evaluate their practice, contributing to overcoming difficulties of teachers on a daily basis.

In order to fulfill our goals the theoretical conceptions concerning the meaninful learning in conection with the investigation of mathematics history were taken into account. The classroom research occurred by means of activities which encouraged the learner to investigate his own concepts on the conic sections. The results of the proposed activities showed the effectiveness and the efficiency of such a methodology as regards the making up of the required knowledge. They also reveal that the investigation in the classroom guides the ones involved, in this process, to have a wider look at the origins, the methods used and the several representations presented by mathematics that certainly lead, specially the students, to a meaninful learning / Neste trabalho, analisamos as possibilidades did?ticas de uso da investiga??o em sala de aula, a partir de uma experi?ncia com estudantes do ensino m?dio no Centro Federal de Educa??o Tecnol?gica da Para?ba CEFET PB, na qual abordamos o estudo das sec??es c?nicas. Para o alcance dos nossos objetivos tomamos como aporte te?rico as concep??es referentes ? aprendizagem significativa em conex?o com a investiga??o em hist?ria da matem?tica. A pesquisa em sala de aula efetivou-se atrav?s de atividades que instigaram, no aprendiz, o desejo de investigar os conceitos pr?prios das sec??es c?nicas. Os resultados das atividades propostas e postas em pr?tica mostraram a efic?cia e a efici?ncia de tal metodologia na constru??o do conhecimento requerido, nos mostrando que a investiga??o em sala de aula conduz os envolvidos, nesse processo, a olhar de forma mais globalizante para as origens e os m?todos utilizados para desenvolver, al?m das v?rias representa??es apresentadas pela matem?tica, o que, certamente conduz, principalmente os alunos, a uma aprendizagem significativa

We used the constructivist approach; using to Richard s Skemp (1980) theory in order to explicit the students learning according to their comprehension levels. Initially, we carry out an exploratory research to check the participant s previous knowledge. Then, we developed an intervention to validate an education module, structured from needs pointed out from results of the initial research, analyzing the students advances through the final evaluation, displaying growth stages of group front to the knowledge about the matter approached. Finally, we presented our reflections about our experience; putting forward suggestions of the teachers activities, aiming at contributing to the improvement of their practices in classroom during the approach of subject for us investigated / Este trabalho relata a nossa experi?ncia em uma pr?tica investigativa na sala de aula, realizada na Escola Estadual Jorge Fernandes , situada em Natal/RN, tendo como objetivo validar a aplica??o de um m?dulo de ensino sobre medidas e grandezas, no ensino fundamental. Utilizamos uma abordagem construtivista, recorrendo ? teoria de Richard Skemp (1980) para categorizar a aprendizagem dos alunos, de acordo com seus n?veis de compreens?o. Inicialmente realizamos uma pesquisa explorat?ria para verificar os conhecimentos pr?vios dos participantes. Em seguida desenvolvemos uma interven??o para validar o m?dulo de estudo, estruturado a partir das necessidades apontadas pelos resultados obtidos na pesquisa inicial, analisando os avan?os dos alunos atrav?s de uma avalia??o final, explicitando o grau de crescimento do grupo quanto a aquisi??o do conhecimento acerca do tema trabalhado.

No. of bitstreams: 1 PaulaBO_DISSERT.pdf: 2811881 bytes, checksum: 6bed5e9f4e661648ada9bf97521c6b56 (MD5) Previous issue date: 2013-07-31 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Normally initial teacher training has not been sufficient to provide all the tools for an updated and efficient teaching practice. It is presented here one of the ways of working the completion of the initial training through a course of continuing education. This course is based on inquiry teaching which is considered an important teaching strategy for science education. This kind of teaching enables improvement of students reasoning and cognitive skills, the cooperation among them, the understanding of the nature of scientific work, and the motivation to think about the relationship between science, technology, society and environment. For this dissertation a course of continuing education based on this approach was followed in order to evaluate which contributions it can bring to the teaching practice. The course was followed based on three stages: on the first there was a questionnaire and an informal interview; next it happened through participant observation with audio and visual aid; the third stage happened through semi structured interview. The collected information was analyzed based on Content Analysis. An inquiry teaching pedagogical material was produced for the course including some examples and applications of this approach. The aim of the material is that it can be a support for the teachers after de course. The results allowed seeing that the course was very useful, different from the traditional and the teachers that put the approach to use found it to be very positive. Thus it can be said that some of the teachers who participated will try again to apply it, try to contextualize more the teaching situations with the students day to day life, as well make them more active and critic. We can also gather from the study, that the inquiry teaching is a very different tool from what the teacher was taught and is accustomed to use and the theoretical comprehension, acceptance and practice change is a complicated process and demands time / Normalmente a forma??o inicial n?o tem sido suficiente para proporcionar todas as ferramentas para uma pr?tica docente atualizada e eficaz. Aqui se apresenta uma das maneiras de se trabalhar a complementa??o da forma??o inicial: um curso de forma??o continuada. Neste curso trabalha-se o ensino por investiga??o que vem sendo considerado como uma importante estrat?gia did?tica para realizar o ensino de ci?ncias. Essa perspectiva de ensino possibilita: o aprimoramento do racioc?nio e das habilidades cognitivas dos alunos, a coopera??o entre eles, a compreens?o da natureza do trabalho cient?fico e o pensamento nas rela??es ci?ncia, tecnologia, sociedade e ambiente. Para essa disserta??o se busca caracterizar quais contribui??es um curso de forma??o continuada, baseado no ensino por investiga??o, traz para a pr?tica de ensino. Para tal foi acompanhado o desenvolvimento dos professores durante e ap?s o curso. O acompanhamento ocorreu em tr?s etapas: a primeira com a aplica??o de um question?rio e uma entrevista informal; a seguinte por meio da observa??o participativa do curso com aux?lio audiovisual; a terceira com uma entrevista semiestruturada. O material coletado foi analisado com base na An?lise de Conte?do. Para os professores cursistas foi produzido um material did?tico com base na pesquisa bibliogr?fica sobre o ensino por investiga??o. Ele apresenta uma fundamenta??o do ensino por investiga??o incluindo tamb?m alguns exemplos e aplica??es dessa abordagem, para que possa servir de ponto de apoio para os professores ap?s o curso. Com a an?lise dos resultados, percebeu-se que o curso foi tido como muito proveitoso, diferente do tradicional e os que aplicaram obtiveram resultados muito positivos com seus alunos. Assim acredita-se que alguns docentes que participaram da forma??o tentar?o aplicar novamente uma atividade investigativa, procurar?o contextualizar mais as situa??es de ensino com o cotidiano do aluno, bem como torn?-lo mais ativo e cr?tico. Al?m disso, conclui-se que o ensino por investiga??o ? uma ferramenta did?tica bastante diferente do que o docente foi apresentado na sua forma??o e utiliza no dia a dia, assim a compreens?o do embasamento te?rico, a aceita??o e mudan?a da pr?tica docente para aplica??o de uma aula investigativa ? um processo que demanda um esfor?o adicional por parte do professor
