The work seeks answers to the following questions: in what form can dynamic geometry environments contribute in students attempts to construct mathematical arguments and proof? What difficulties and resistances emerge in learning situations which address the concept of parallelism in analytic geometry? To respond to these questions, sequences of activities, based on some aspects of didactical engineering was designed. For the conception of these activities, the research drew from the work of Parsysz concerning the levels of development of geometrical thinking and the analysis of students´ interactions with the activities was based on the Balacheff´s classification of different types of proof. Analysis of the results obtained in the application of the activity sequence showed that the dynamic geometry environment contributed to the creation of situations that supported the construction of meanings for the concept of parallelism and that the students engaged with the activities in the manner proposed, producing some kind of relevant proof / Esta dissertação tem por objetivo fazer um estudo sobre argumentação e prova envolvendo o paralelismo no ensino da geometria analítica. O trabalho procura responder às seguintes questões: de que forma os ambientes de geometria dinâmica contribuem para que os alunos construam suas argumentações e provas? Quais são as dificuldades ou resistências que se apresentam na situação de aprendizagem do conceito de paralelismo no ensino da geometria analítica? Para responder a esse questionamento, foi concebida uma seqüência de atividades baseada em alguns elementos da engenharia didática. Para a concepção das atividades a pesquisa se apoiou nos trabalhos de Parsysz sobre os níveis do desenvolvimento do pensamento geométrico e para as análises das atividades, na tipologia de provas de Balacheff. A análise dos resultados obtidos na aplicação da seqüência mostrou que o ambiente de geometria dinâmica contribuiu para a criação de situações que ajudaram na construção do conceito de paralelismo e que os alunos alcançaram os objetivos propostos satisfatoriamente e produziram algum tipo de prova

Among them is the inappropriate use of smartphones / tablets for students, among the academic activities. These mobile devices, for their variety of prices are available for everyone, and because of that they are present in almost all parts of the day. Smartphones / tablets today have thousands of applications for many different uses, no matter the operational system they use. On the other hand, in the educational field, these devices are not yet part of the classroom routine productively; on the opposite, are elements of distraction to the students. In an attempt to take advantage of this feature as a pedagogical tool for the teaching of math, taking advantage of the presence of the students equipments in classes, came the proposal to create and use an application called AGA, which runs on the Android operating system, for the use in classes that addressed primary topics of analytic geometry, such as marking points in the Cartesian point and distance between points on the plane. It is important to highlight that among the available operating systems, Android dominates the smartphone / tablet market. The building application for this research was developed through an integrated development environment MIT (Massachusetts Institute of Technology). It is a simple and interactive way to build applications for the Android operating system for mobile devices. The use of the application in mathematics lessons took place in a class of the third year of high school in a state school, located in Serop?dica City. For the assessment of the experiment, they were applied in the research group, tests before and after the activities, addressing the working content and motivation to study mathematics. Such tests allowed the analysis of the impact of the work developed in class and efficiency of the construction and use of the AGA. / Existem diversos fatores que dificultam o desenvolvimento do trabalho dos professores de matem?tica na educa??o b?sica.

Os smartphones/ tablets atuais disp?em de milhares de aplicativos para as mais diversas utiliza??es, independente do sistema operacional que utilizam. Por outro lado, no campo educacional, aparelhos como estes ainda n?o fazem parte da rotina de sala de aula de forma produtiva; ao contr?rio, s?o elementos de distra??o para os discentes. Em uma tentativa de aproveitar esse recurso como ferramenta pedag?gica para o ensino de matem?tica, aproveitando a presen?a dos equipamentos dos alunos nas aulas, surgiu a proposta de cria??o e de uso de um aplicativo, denominado AGA, o qual funciona no sistema operacional Android, para utiliza??o em aulas que abordassem t?picos preliminares de Geometria Anal?tica, tais como marca??o de pontos no plano cartesiano e dist?ncia entre pontos no plano. Vale destacar que, dentre os sistemas operacionais dispon?veis, o Android domina o mercado de smartphones/ tablets. A constru??o do aplicativo para esta pesquisa foi desenvolvida atrav?s de um ambiente de desenvolvimento integrado do MIT (Massachussetts Institute of Tecnology).

Considérons une variété régulière analytique M sur le corps réel ou complexe, un faisceau d'idéaux J défini sur M, un diviseur à croisement normaux simples E et une distribution singulière involutive Θ tangent à E.L'objectif principal de ce travail est d'obtenir une résolution des singularités du faisceau d'idéaux J qui préserve certaines ``bonnes" propriétés de la distribution singulière Θ. Plus précisément, la propriété de R-monomialité : l'existence d'intégrales premières monomiales. Ce problème est naturel dans le contexte où on doit étudier l'interaction d'une variété et d'un feuilletage et, donc, est aussi reliée au problème de la monomilisation des applications et de résolution ``quasi-lisse" des familles d'idéaux.- Le premier résultat donne une résolution globale si le faisceau d'idéaux J est invariant par la distribution singulière;- Le deuxième résultat donne une résolution globale si la distribution singulière Θ est de dimension 1 ;- Le troisième résultat donne une uniformisation locale si la distribution singulière Θ est de dimension 2.On présente aussi deux utilisations des résultats précédents. La première application concerne la résolution des singularités en famille analytique, soit pour une famille d'idéaux, soit pour une famille de champs de vecteurs. Pour la deuxième, on applique les résultats à un problème de système dynamique, motivé par une question de Mattei. / Let M be an analytic manifold over the real or complex field, J be a coherent and everywhere non-zero ideal sheaf over M, E be a reduced SNC divisor and Θ an involutive singular distribution everywhere tangent to E. The main objective of this work is to obtain a resolution of singularities for the ideal sheaf J that preserves some ``good" properties of the singular distribution Θ. More precisely, the R-monomial property : the existence of local monomial first integrals. This problem arises naturally when we study the ``interaction" between a variety and a foliation and, thus, is also related with the problem of monomialization of maps and of ``quasi-smooth" resolution of families of ideal sheaves.- The first result is a global resolution if the ideal sheaf J is invariant by the singular distribution Θ;- The second result is a global resolution if the the singular distribution Θ has leaf dimension 1;- The third result is a local uniformization if the the singular distribution Θ has leaf dimension 2;We also present two applications of the previous results. The first application concerns the resolution of singularities in families, either of ideal sheaves or vector fields. For the second application, we apply the results to a dynamical system problem motivated by a question of Mattei.

<p>This dissertation explores the ideational underpinnings of the rise of the west through a comparison of ancient Greek geometry, medieval Arabic algebra, and early modern European calculus. Blending insights from Thomas Kuhn, Michel Foucault, and William H. Sewell, I assert that there is an underlying logic, however clouded, to the unfolding of a given civilization, governed by a cultural episteme that delineates the boundaries of rational thought and the accepted domain of human endeavor. Amid a certain conceptual configuration, the rise of the west happens; under other circumstances, it does not. Mathematics, as an explicit exhibition of logic premised on culturally determined axioms, presents an outward manifestation of the lens through which a civilization surveys the world, and as such offers a window on the fundamental assumptions from which a civilization's trajectory proceeds. To identify the epistemological conditions favorable to the rise of the west, I focus specifically on three mathematical divergences that were integral to the development of calculus, namely analytic geometry, trigonometry, and the fundamental theorem of calculus. Through a comparative/historical analysis of original source documents in mathematics, I demonstrate that the logic in the earlier cases is fundamentally different from that of calculus, and furthermore, incompatible with the key developments that constitute the rise of the west. I then examine the conceptual similarities between calculus and several features of the rise of the west to articulate a description of the early modern episteme.</p> / Dissertation

This study aimed to develop a teaching and learning model, based on principles derived from the fields of constructivist theory, schema theory, critical literacy theory, and design theory, to inform the development of hypermedia-mediated learning environments that facilitate the construction of mathematical knowledge by secondary school students in Thailand. In this study, the participants were a group of three secondary school students from the Demonstration school attached to the Faculty of Education at Khon Kaen University (Thailand). In order to ascertain how mathematical learning could be facilitated by the process of designing a web page that could be used to introduce other students to analytic geometry, all three participants were asked to work collaboratively to design an analytic geometry web page. The process of designing the web page was informed by a theoretical model derived from an analysis and synthesis from the research literature on constructivist theory, schema theory, critical literacy theory, and design theory. Findings from the study indicated that the creation of a web page facilitated and enhanced the Thai students' learning about analytic geometry. The major outcomes from the study are a revised theoretical framework to inform the integration of the design of mathematical web pages into Thai mathematics classrooms and a conceptual map framework to assess qualitative and quantitative changes to students' repertoires of knowledge about analytic geometry that emerge during the process of designing a webpage.

Nesta pesquisa, que consiste de um estudo de caso, elaboramos uma sequência didática que prevê atividades que devem ser resolvidas de duas maneiras distintas. Uma das maneiras utiliza conceitos de Geometria Plana – como Teorema de Pitágoras e semelhanças – e a outra maneira utiliza conceitos de Geometria Analítica – como equações de reta e cálculos de área via determinantes. Para analisar os dados coletados, com a aplicação desta sequência, a Teoria de Registros de Representação Semiótica foi utilizada. Duval (2009), autor da teoria, trata sobre a importância dos registros em Ensino de Matemática, sobre a conversão de um registro em outro e sobre a necessidade de utilização de mais de um registro como um meio de entender o modo matemático de pensar. Como meio de dar um suporte a nossa pesquisa, em nossa revisão bibliográfica, procuramos produções recentes, nas quais foram utilizadas a mesma teoria sob o aspecto da conversão, e analisamos também se os livros didáticos de Matemática, do terceiro ano do Ensino Médio, contemplam atividades que incentivem a utilização de mais de um registro para resolução de atividades. Esta sequência foi aplicada em uma turma de alunos do terceiro ano, de uma escola de Ensino Médio Técnico integrado e sua estrutura foi inspirada na Investigação Matemática de Ponte (2006). Nesta pesquisa, os registros, majoritariamente utilizados pelos alunos, foram os de Geometria Plana – Figural – e de Geometria Analítica – Gráfico – e verificamos que os alunos conseguiram, quando solicitados, articular a utilização destes dois tipos de registro. / In this case study we elaborate a didactic sequence that predicts activities that should be solved in two different ways. One of them uses the concepts of plane geometry – such as the Pythagorean theorem and similarities – and the other uses the concepts of analytic geometry – such as the equations of a line and area calculations. To analyze the data assembled with the application of this sequence we used The Theory of Registers of Semiotic Representation. Duval (2009), the author of this theory, addresses the importance of registers in Mathematics Teaching, the conversion of one register to another, and the need to use more than one register as a way to understand the mathematical way of thinking. To support our research, we looked in our bibliographical review for recent articles that made use of the same theory under the conversion aspect, and we also analyzed whether third year high school mathematics textbooks offer activities that encourage the use of more than one register in the solution of activities. This sequence was applied in a class of third-year students, from an integrated technical high school and its structure was inspired by Ponte’s Mathematical Investigation (2006). In this research, the registers most used by the students were those of plane geometry – figure – and of analytic geometry – graph – and we verified that the students, on request, achieved to articulate the use of these two types of registers.

A Teoria dos Registros de Representação, de Duval, compreende e analisa a peculiaridade dos objetos matemáticos, acessíveis através de suas diferentes representações. Fischbein e Hershkowitz, entre outros teóricos, desenvolveram as noções de Imagem Mental e Imagem Conceitual como a interpretação de um dado conceito matemático por um sujeito. Esta dissertação estabelece conexões entre estas duas discussões teóricas e, a partir disto, faz uma proposta de ensino para alguns conceitos de Geometria Analítica através do uso dos registros dinâmicos no software GeoGebra. A proposta, na forma de sequência didática, foi implementada em turma do terceiro ano do Ensino Médio de uma escola da rede particular de ensino do município de Porto Alegre. A análise da produção dos estudantes estabelece diálogo constante com os referenciais teóricos escolhidos. É uma pesquisa, sob a forma de estudo de caso, que busca investigar como ocorre o processo de aprendizagem de Geometria Analítica através utilização do software GeoGebra no ensino e aprendizagem de matemática, apresentando e discutindo os resultados obtidos de modo a contribuir para esta área de pesquisa. / The Registers of Representation Theory, from Duval, understands and analysis the peculiarity of mathematics objects, accessible through its different representations. Fischbein and Hershkowitz, among others researchers, developed the notions of Mental Image and Conceptual Image to explain the construction process of mathematical concepts by the subject. This dissertation establishes connections between these theories and uses this approach to propose a didactic sequence for teaching some concepts of Analytic Geometry using dynamic representation offered by the GeoGebra software. The proposal was implemented in a 3rd grade private high school. The research is a case study. The analysis of students’ production establishes constant dialog with the theoretical approach and presents results that can be a contribution to research in the area of dynamic representations and learning of school mathematics.
