Took part in the research ten teachers who teach Mathematics in middle, high school and college; and, they were selected in public and private schools and at PPGDUCEM ? located in the city of Porto Alegre, in Rio Grande do Sul state ? RS, also participated in the research twenty-six students of the 8th grade of elementary school of a private school in the city of Porto Alegre. For the data collect, it was used as instruments: questionnaires answered by teachers and students, a daily map in which the students registered their activities and a field diary whereby the researcher took notes his observations. The answers given by the teachers and by the students were analyzed through a qualitative method, via Discursive Textual Analysis, connecting categories a priori and emerging subcategories. The theoretical input used as the basis of this study were related to authors like Vigotsky (1998), Vergnaud (1990), Moran (2000), Demo (2000), D?Ambrosio (2014), Machado (2014), among others. For the rationale of the analysis, it was used the results of Demo?s studies (2000) about the assumptions of teaching by research. The analysis had three categories a priori, among them: reconstructive questioning, everyday attitude survey and competence constitution. Stem from these categories, it was possible to describe the collected data analysis, emerging, this way, into subcategories. It was possible, either, to affirm that problem solving is the most used strategy to teach mathematics and, focusing on technology, teachers still choose much older softwares such as Geogebra and Graphmath. The teacher perceives the Mathematics teaching articulated with contextualized activities involving technology as part of people?s everyday lives. Therefore, it was noticed that students find difficulties in solving contextualized activities, although it is confirmed, through this study, that web research eases the learning processes, the learners cannot identify the Mathematics knowledge used in this kind of task. / Esta pesquisa tem como objetivo compreender como as atividades contextualizadas, por meio da educa??o pela pesquisa, e guiadas pela Teoria dos Campos Conceituais podem contribuir para a aprendizagem dos estudantes no ensino da Matem?tica. Participaram da pesquisa dez professores que ensinam Matem?tica nos anos finais do ensino fundamental, m?dio e superior; selecionados em escolas p?blicas, privadas e no PPGDUCEM - da cidade de Porto Alegre, localizada no Estado do Rio Grande do Sul ? RS, tamb?m participaram da pesquisa 26 estudantes do 8? ano do ensino fundamental de uma escola privada da cidade de Porto Alegre. Para coleta de dados, foram utilizados como instrumentos: question?rios respondidos pelos professores e pelos estudantes, um mapa di?rio no qual os estudantes registravam suas atividades e um di?rio de campo em que o pesquisador anotava suas observa??es. As respostas dadas pelos professores e pelos estudantes foram analisadas atrav?s de m?todo qualitativo, por meio de An?lise Textual Discursiva, relacionando categorias ? priori e subcategorias emergentes. Os aportes te?ricos que embasaram este estudo foram autores como Vigotsky (1998), Vergnaud (1990), Moran (2000), Demo (2000), D?Ambrosio (2014), Machado (2014), entre outros. Para a fundamenta??o da an?lise, foram utilizados os resultados dos estudos de Demo (2000) acerca dos pressupostos da proposta sobre o educar pela pesquisa. A an?lise dos dados teve tr?s categorias ? priori, dentre elas: questionamento reconstrutivo, pesquisa de atitude cotidiana e forma??o da compet?ncia. A partir dessas categorias, foi poss?vel descrever a an?lise dos dados coletados, emergindo, assim, em subcategorias. Foi poss?vel, tamb?m, afirmar que a resolu??o de problemas ? a estrat?gia mais utilizada para ensinar Matem?tica e, se tratando da tecnologia, professores ainda optam por softwares bastante antigos como Geogebra e Graphmath. O docente percebe o ensino da Matem?tica articulado com atividades contextualizadas envolvendo as tecnologias como uma parte do dia a dia das pessoas. Dessa forma, p?de-se notar que os estudantes encontram dificuldades na resolu??o de atividades contextualizadas, embora se confirme, por meio desse estudo, que a pesquisa na web facilita a aprendizagem, os alunos n?o conseguem identificar os conhecimentos Matem?ticos utilizados nesse tipo de tarefa.

A metodologia adotada foi a pesquisa qualitativa, desenvolvida no pr?prio ambiente escolar. Os instrumentos utilizados na coleta dos dados pesquisados foram: a observa??o, caderno de anota??es e question?rios. Os dados coletados atrav?s das atividades foram tratados, analisados e apresentados atrav?s de tabelas e gr?ficos. A an?lise mostrou que a implementa??o de um LEM tem?tico pode contribuir para o desenvolvimento de atividades interdisciplinares e propiciar a participa??o dos alunos em atividades de investiga??o. / This work presents a proposal to build a Mathematics Teaching Laboratory (MTL) whose main theme is the study, construction and use of instruments for navigation and location of mathematical content in an interdisciplinary way approach, and develop a notebook of activities focused on navigational instruments. For this it was necessary a literature review to understand the different conceptions of MTL and its pedagogical implications. The methodology used was literature research, construction and handling of instruments, and pedagogical experimentation. Lorenzato (2006) highlights the importance of an environment and suitable for a professional who can do a good job instruments. The implementation of an LEM can find some obstacles. The lack of support from other teachers or the management, the lack of a suitable place to store the materials produced, the lack of time in the workload of the teacher to prepare the lab activity, etc. Even in unfavorable or adverse conditions, according Lorenzato (2006), its implementation will benefit teachers and students. The lack of teacher training in their initial and continuing education, to use materials, and the lack of manuals with lab activities are also mentioned as factors that keep teachers from MTL. With prop?posito assist the teacher of elementary or middle school in building a theme MTL prepared and we are providing a notebook of activities that provides a didactic sequence involving History and Mathematics. The book consists of four accompanied by suggestions for teachers activities, however the teacher has full autonomy to adapt the activities to the reality of your school. Among the instruments of navigation presented in this study chose to build the quadrant due to its simplicity, low cost of material and great teaching potential that this instrument has. But a theme lab is always being built and rebuilt as it is a research environment

Regarding the elevation of Mathematics Education or the teaching of school mathematics are many as tools that enable a constructivist learning process (the student is the focus of learning and constructs his knowledge alone, with only a brief teacher's mediation) and that On the realization of an effective practice. Thus, the present study was developed in order to clarify and explain understandings of some of the main Information and Communication Technologies that can be implemented to make mathematics teaching feasible and also in a test of classroom experience and the benefits of using the tools of Information and Communication. / Em meio ? era informacional se fazem necess?rias a aproxima??o e a adequa??o da did?tica e da metodologia em sala de aula com as possibilidades colocadas pelo uso das chamadas Tecnologias de Informa??o e Comunica??o (TIC?s) que emergiram ainda no final do s?culo XX, muito timidamente, e ainda se encontram em apogeu de utiliza??o e possibilidades nos dias atuais.

In their narratives, the professors organized and redid their personal and professional paths under the stimulus of their projects of identity and their relation with technologies. To have the understanding regarding the formation of a Math professor, the starting point was to clarify not only the way the first Math professors of Brazil got their academic formation in the moment they created the universities; but also, point out the origin of this model of professor in this subject. With time, modifications occur with the creation of technologies and its insertion in Math classes. Following a perspective of qualitative research, the methodological proposition ?Hist?ria Oral de Vida? (Oral History of Life), we used interviews with 12 Math professors who have experience teaching undergraduate courses in Math. The narratives allowed visibility in the Math academic field in the period of three generations of professors and the comprehension of technological advancement to learn, teach and think Math. / Esta pesquisa tem por objetivo apresentar e analisar as narrativas de professores de Matem?tica do Estado do Rio Grande do Sul, que no conjunto permitiram compreender o seu pensamento e a sua pr?tica pedag?gica.

It is believed that problems related to the learning of mathematics have their origin in the early years of elementary school, where students are expected to learn the basis of mathematical knowledge. However, evidence found in this study points out that the teacher who is in the classroom at this stage, in most cases, does not have the necessary training related to the concepts and mathematical contents necessary to teach mathematics in a contextualized and creative way. The insufficient training related to Mathematics in the undergraduate courses in Pedagogy causes to teachers who already work or will work in schools, in the early years, gaps that are not healed in their initial training. It is assumed that students of Pedagogy know such contents and that they have been acquired in their formation in elementary school, prior to their admission in the undergraduate course, a fact that does not seem to be confirmed. This idiosyncrasy ends up passing on responsibility for this training to the student of Pedagogy and not to the undergraduate course. This qualitative-exploratory research, supported by a case study involving invited teachers from public and private schools in the Porto Alegre and professors of Pedagogy undergraduate courses, aimed to investigate the formation of pedagogues, regarding the teaching of Mathematics in the early years of elementary school, trying to identify possible gaps and alternatives of continuing education, especially those who have access to the use of open digital spaces / resources. Some of the theoretical references used are: Tardif, N?voa, L?vy, Prensky, Lorenzato and Nacarato. As a result of this research, it is highlighted the approach given in the undergraduate courses in Pedagogy focused on the methodological aspects of mathematics teaching, not contemplating the specific training of the mathematical contents that will be taught by these teachers. The study also emphasized that open digital spaces / resources are not being discussed and / or used in teachers? training in the early years of elementary school, so it is difficult to use these spaces and resources in both continuing education and teaching practice. Something significant that was found in the research was that there are mathematics laboratories in some private schools, which rely on materials and specialists to support mathematics teaching as well as teacher training. Another interesting data found in the research was the continuing education in service, especially in private schools, something that helps in the reconstruction and re-signification of teacher's relationship with Mathematics, allowing him/her to teach a different way of how he/she learned. It is expected that this study has provided elements for a reflection on the need to revise the curricula of Pedagogy courses in a broader perspective than just the inclusion of one or more subjects dealing with mathematical contents. Also, it is expected that this research points out alternatives for teachers or future teachers on how to look for complementary training using the open digital spaces / resources available online. / A aprendizagem de Matem?tica reside como um desafio na forma??o dos estudantes, embora sua import?ncia na sociedade nunca tenha sido t?o significativa e necess?ria como a partir do avan?o das tecnologias digitais. Acredita-se que os problemas relacionados ? aprendizagem de Matem?tica tenham sua origem nos anos iniciais, em que se espera que os estudantes aprendam a base do conhecimento matem?tico. No entanto, as evid?ncias encontradas nessa investiga??o apontam que o professor que est? em sala de aula, nesta etapa, na maioria dos casos, n?o possui a forma??o relacionada aos conceitos e conte?dos matem?ticos necess?rios para ensinar Matem?tica de forma contextualizada e criativa. A forma??o insuficiente relacionada ? Matem?tica nos cursos de Licenciatura em Pedagogia faz com que os docentes que j? atuam ou ir?o atuar na escola, nos anos iniciais, apresentem lacunas que n?o s?o sanadas na sua forma??o inicial. Pressup?e-se que os estudantes de Pedagogia saibam tais conte?dos e que esses tenham sidos adquiridos na sua forma??o b?sica, pregressa ? sua entrada no Ensino Superior, fato este que n?o se confirma. Esta idiossincrasia acaba repassando a responsabilidade para esta forma??o ao pr?prio estudante de Pedagogia e n?o para seu curso. Esta pesquisa de cunho qualitativo-explorat?ria, apoiada em estudo de caso envolvendo professores convidados de escolas p?blicas e privadas do munic?pio de Porto Alegre e professores formadores dos cursos de Licenciatura em Pedagogia, buscou investigar a forma??o dos pedagogos, no que tange ao ensino de Matem?tica nos anos iniciais, visando identificar poss?veis brechas e alternativas de forma??o continuada, especialmente aquelas que contemplam o uso de espa?os/recursos digitais abertos. Dentre os referenciais te?ricos utilizados, destacam-se: Tardif, N?voa, L?vy, Prensky, Lorenzato e Nacarato. Como resultado desta investiga??o, destaca-se a abordagem dada nos cursos de Licenciatura em Pedagogia voltada aos aspectos metodol?gicos do ensino de Matem?tica, n?o contemplando a forma??o espec?fica dos conte?dos matem?ticos que ser?o ensinados nos anos iniciais. A pesquisa tamb?m destacou que os espa?os/recursos digitais abertos n?o est?o sendo discutidos e/ou utilizados na forma??o do professor de anos iniciais, dificultando, assim, a sua utiliza??o tanto para a forma??o continuada quanto para a pr?tica docente. Um achado significativo na pesquisa foi a presen?a dos laborat?rios de Matem?tica nas escolas privadas, as quais contam com materiais e especialistas como suporte ao ensino de Matem?tica, bem como ? forma??o docente. Outro achado da pesquisa foi a forma??o continuada em servi?o, de modo especial nas escolas privadas, que auxiliam na reconstru??o e ressignifica??o da rela??o do professor com a Matem?tica, permitindo que ele ensine de um modo diferente de como aprendeu. Espera-se que esta investiga??o tenha fornecido elementos para uma reflex?o acerca da necessidade de revisar os curr?culos de forma??o da Pedagogia numa perspectiva mais ampla do que apenas a inclus?o de uma ou mais disciplinas tratando de conte?dos matem?ticos. E, tamb?m, apontar alternativas para que docentes ou futuros docentes busquem forma??o complementar usando os espa?os/recursos digitais abertos dispon?veis na internet.

I believe that a database as contributions and impact for the video game "Audiogeometry" can be offered as a methodological resource in the relation between teaching and learning within this community. The video game "Audiogeometry" is presented as a resource, as well as an object of study and support, composed of sound-based and haptic interfaces for the development of skills that are related to the mathematical-geometric thinking of the blind student. The methodologies of analysis in the construction and the interpretation of mental models for the development of skills in geometry in the case of blind and low vision students, was supported by the Van Hiele?s Theory. Thus, in this work we defend the thesis that the videogame Audiogeometry contributes to the development of geometric thinking in Van Hiele's perspective. / Diante das dificuldades encontradas por alunos com defici?ncia visual inclu?dos no sistema regular de ensino, no tocante a determinadas disciplinas, em particular a Matem?tica, apresenta-se nesta investiga??o um olhar voltado para o desenvolvimento do pensamento geom?trico por um grupo de estudantes cegos e de baixa vis?o. A tese tem como base as contribui??es e o impacto que o videojogo ?Audiogeometria? pode oferecer como recurso metodol?gico utilizado na rela??o ensino e aprendizagem dentro desse grupo. Apresenta-se o Videojogo ?Audiogeometria? como recurso, e tamb?m como objeto de estudo e apoio, composto de interfaces baseadas em som e em h?ptica para desenvolvimento de habilidades que estejam relacionadas ao pensamento matem?tico-geom?trico do cego. O objetivo desta tese ? investigar e comprovar as poss?veis contribui??es do uso do Videojogo ?Audiogeometria? com sujeitos deficientes visuais para o desenvolvimento do pensamento geom?trico. As bases metodol?gicas de an?lise na constru??o e interpreta??o foram apoiadas na teoria dos modelos mentais para o desenvolvimento de habilidades em geometria, no caso dos estudantes cegos e de baixa vis?o, apoiados na Teoria de Van Hiele.

In an attempt to reverse this situation and facilitate the learning of existing subjects in Trigonometry and Geometry, basic astronomical knowledge related to sundials, allied to concepts of Geography with respect to Geographic Coordinates and Earth Movements, were used. Activities were carried out with students from Elementary and Middle School, such as: workshops, classes and events related to the construction and positioning of Sun Clocks. As a final product, we made different Equatorial Type Sun Clocks, as well as a Didactic Sequence for teachers of education basic. / O estudo focalizado nesta Disserta??o foi realizado no Col?gio Estadual Alaor Coutinho - CEAC, localizado em Praia do Forte, munic?pio de Mata de S?o Jo?o ?

The I.T. labs set up in public schools, which are high cost investments, often get forgotten and become obsolete. Nowadays, with technology evolution and the appearance of smartphones and tablets, new educational apps are being developed for these tools. Many discussions have been held regarding the real applicability of such tools, if they can really help or simply distract the student, but it is a known fact that they are present all the time and that it is worthy to use them in order to improve the learning experience. Sketchometry is a dynamic geometry app with basic commands that could help students with geometry and mathematical functions. The moving of constructions, usually made by gestures and with the imagination of teachers, can now be done with the touch of fingers on the screens of mobile phones and tablets, making visualization easier. Teachers, however, still have difficulties implementing such tools in their classes. This essay attempted to evaluate the opinion of students of primary school, undergraduates, masters degree students and masters on the usage of smartphones/tablets in class. Activities with Sketchometry were shown, followed by an evaluation questionnaire for the research. The results obtained indicate that some of the reasons provided not to use the tools, are the number of students per classroom, the lack of structure in schools and the lack of skill of teachers. When it comes to licentiates, master's degree students and graduates from UFRRJ's PROFMAT, the majority of teachers and soon to be teachers believe in the usage of the tools, that the students are interested in using them and that there are indeed obstacles but they are not insuperable. / O ensino da Matem?tica muda lentamente, enquanto o perfil dos alunos muda a cada gera??o. Os laborat?rios de inform?tica montados nas escolas p?blicas, investimento de alto custo, muitas vezes ficam abandonados e se tornam obsoletos. Atualmente, com a evolu??o da inform?tica e o surgimento de celulares e tablets com tecnologia touchscreen, novos aplicativos educativos t?m sido desenvolvidos para essas ferramentas. Muito se tem discutido acerca da real aplicabilidade desses equipamentos, se podem realmente auxiliar na aprendizagem ou se apenas distraem o aluno, mas o certo ? que eles est?o presentes a todo momento e que vale a pena se valer disso para buscar melhorar o aprendizado. O Sketchometry ? um aplicativo de geometria din?mica, com comandos simples, que pode ajudar o estudante no estudo da geometria e de fun??es Matem?ticas. A movimenta??o das constru??es, antes feita com gestos e imagina??o por tantos professores, hoje pode ser realizada com o toque dos dedos nas telas de celulares e tablets, facilitando a visualiza??o. Os professores, no entanto, ainda t?m dificuldades em implementar esse tipo de ferramenta em suas aulas. Este estudo buscou avaliar a opini?o de estudantes do ensino fundamental, graduandos, mestrandos e mestres acerca da utiliza??o de celulares/tablets em sala de aula. Atividades com o Sketchometry foram realizadas e, em seguida, um question?rio de avalia??o para a pesquisa foi aplicado. Nos resultados obtidos, observou-se que entre os motivos citados para a n?o utiliza??o dessas ferramentas, est?o o n?mero de alunos por sala, a falta de estrutura nas escolas, o despreparo do pr?prio professor, entre outros. Com rela??o aos licenciandos, mestrandos e egressos do PROFMAT da UFRRJ, a maioria dos professores e futuros professores acredita na utiliza??o desse tipo de ferramenta, e que existe interesse dos alunos para que sejam utilizadas, que os obst?culos existem mas n?o s?o intranspon?veis.

As discuss?es levantadas sinalizam para possibilidades concretas de entrela?amento entre os conte?dos matem?ticos extra?dos do bojo da obra com metodologias de ensino atuais a partir do redimensionamento do uso de cartas pedag?gicas segundo a perspectiva freireana da correspond?ncia e, principalmente da utiliza??o de novas vias de comunica??o do s?culo XXI, ambas visando o di?logo e a aproxima??o entre quem escreve e quem l?. / Lettres ?une Princesse d'Allemagne sur divers sujets de physique et de philosophie (Letters to a Princess of Germany on various topics of physics and philosophy) is the work taken as an object of study of this thesis. It is a literary success written in the eighteenth century by the Swiss mathematician and physicist Leonhard Paul Euler (1707-1783) in order to meet a request from the Prussian king, Frederick II, the Great (1712-1786) to accept to guide the intellectual education of his niece, the young princess Anhalt-Dessau (1745-1808). The method of teaching and learning through letters elected to the education of the German monarch resulted in a collection of 234 matches in which Euler theory is about music, Philosophy, Mechanics, Optics, Astronomy, Theology and Ethics among others. The research seeks to point out mathematical content contained in this reference work based on the exploitation and adaptation of original historical works as an articulator of development activities for teaching mathematics in basic education and in accordance with the National Curriculum Parameters of Mathematics (NCP) work. The general objective point out the limits and didactic potential of Lettres ? une Princesse d'Allemagne sur divers sujets de physique et de philosophie as a source of support for teachers of basic education in developing activities for teaching mathematics. The discussions raised point to concrete possibilities of entanglement between the extracted mathematical content of the bulge of the work with current teaching methodologies from resizing the use of letters according to Freire's pedagogical perspective of the correspondence, and especially the use of new communication channels in the century XXI, both aimed at dialogue and approximation between those who write and those who read.

Em contrapartida, a profici?ncia em leitura constituise como um dos objetivos centrais da escola, sendo essencial aos diferentes componentes curriculares, como tamb?m ?s pr?prias demandas de intera??o requeridas pela sociedade. Devido a tal relev?ncia iremos analisar os elementos intr?nsecos ? forma??o leitora dos nossos alunos. Nesse sentido, o objetivo geral desta pesquisa consiste em analisar qual a abordagem dada aos g?neros discursivos nos livros did?ticos de matem?tica, aprovados pelo Programa Nacional do Livro Did?tico (PNLD 2013) e adotados nos anos iniciais do Ensino Fundamental da rede p?blica de ensino. Tais mat?rias correspondem ?s cole??es adotadas em escolas da rede p?blica municipal de Mossor?/RN. No desenvolvimento das an?lises desta pesquisa, nos fundamentamos, na perspectiva de Bakhtin (2011, 2014) acerca dos g?neros do discurso, nos apoiamos tamb?m nos estudos de Leite e Barbosa (2014), Schneuwly e Dolz (2011), Marcuschi (2008), Machado (2002), Vigotski (2008), Freire (1996), Smole e Diniz (1999), Lopes e Nacarato (2009). Esta pesquisa contribuir? para elabora??o de pol?ticas que sejam voltadas ao PNLD (Programa Nacional do Livro Did?tico), ? leitura e ao ensino de matem?tica a partir do que os dados venham a sinalizar e tamb?m colaborar com estudos que possam gerar dados que venham a auxiliar os autores na elabora??o de conte?dos e atividades do Livro Did?tico (LD). / From the official indicators Education Development Index Basic (IDEB), Programme for International Student Assessment (PISA) and Proof Brazil, it is possible to perhaps that a large proportion of the problems related to poor learning of students completing the early years of elementary school is because of low reading proficiency. This fact has been point out as a major problem of compulsory basic education as evidenced by low rates in tests. On the other hand, reading proficiency is constitute as one of the schools main objectives and is essential to the different curriculum components, as well as to the specific demands of interaction required by society. Examine the relation between intrinsic elements and the reader formation of our students. The major objective of this research is to analyze what approach given to genres in textbooks of mathematics, approved by Programa Nacional do Livro Did?tico (PNLD 2013) and adopted in the early years of public elementary school. Such materials correspond to collections taken in the municipal public schools network Mossor?/RN. The research development, in fundamentals, is based on Bakhtin (2011, 2014) perspective on genders discourse. Besides that, Leite & Barbosa (2014), Schneuwly & Dolz (2011), Marcuschi (2008), Axe (2002), Vygotsky (2008), Freire (1996), Smole & Diniz (1999), Lopes & Nacarato (2009), studies support this idea. This research will contribute to developing policies that are aimed at PNLD (National Textbook Program), to reading and mathematics education from the data may signal and also collaborate with studies to generate data that will assist authors in the elaboration of contents and activities Textbook (LD).
