(1797), de Lorenzo Mascheroni (1750 - 1800). Para isso, foi realizada uma pesquisa qualitativa caracterizada por uma explora??o hist?rica de car?ter bibliogr?fico seguida de uma interven??o emp?rica, com base no uso da Hist?ria da Matem?tica aliado ? TIC via Investiga??o Matem?tica. Assim, foram realizados estudos em trabalhos que tratassem do tema, assim como uma pesquisa para evidenciar problemas e/ou epis?dios da Hist?ria da Matem?tica que podem ser resolvidos com o aux?lio das TIC, permitindo a produ??o de um caderno de atividades abordando a resolu??o de problemas hist?ricos num ambiente computacional. Nessa busca, deparamo-nos com os problemas de Geometria que s?o apresentados por Mascheroni na obra indicada anteriormente, para os quais sugerimos solu??es e investiga??es usando o software GeoGebra. A pesquisa resultou na elabora??o de um produto educacional, um caderno de atividades, o qual foi estruturado de modo a permitir que durante a sua execu??o os alunos pudessem realizar investiga??es hist?ricas e/ou Matem?tica, para tanto, apresentamos os procedimentos para realiza??o de cada constru??o, seguidos em alguns momentos pela solu??o original da obra. Ao mesmo tempo, estimulamos os discentes a investigarem/refletirem a sua constru??o (no GeoGebra), bem como a fazerem compara??es com a solu??o de Mascheroni. Este caderno foi aplicado em duas turmas da disciplina Did?tica da Matem?tica I (MAT0367) do curso de Licenciatura em Matem?tica da UFRN em 2014. Sabendo da exist?ncia de alguns argumentos desfavor?veis quanto a utiliza??o da Hist?ria da Matem?tica, como por exemplo, a perda de tempo, constatou-se que este fator pode ser atenuado com o aux?lio do recurso computacional, pois, podemos fazer verifica??es utilizando apenas o dinamismo do software e sem repetir a constru??o. Vale salientar que o tempo minimizado n?o significa perda de reflex?o nem matura??o das ideias, quando adotado o processo de Investiga??o hist?rica e/ou Matem?tica / The present work aims to show a possible relationship between the use of the History of Mathematics and Information and Communication Technologies (TIC) in teaching Mathematics through activities that use geometric constructions of the ?Geometry of the Compass? (1797) by Lorenzo Mascheroni (1750-1800). For this, it was performed a qualitative research characterized by an historical exploration of bibliographical character followed by an empirical intervention based on use of the History of Mathematics combined with TIC through Mathematical Investigation. Thus, studies were performed in papers dealing with the topic, as well as a survey to highlight problems and /or episodes of the history of mathematics that can be solved with the help of TIC, allowing the production of a notebook of activities addressing the resolution of historical problems in a computer environment. In this search, we came across the problems of geometry that are presented by Mascheroni stated previously in the work that we propose solutions and investigations using GeoGebra software. The research resulted in the elaboration of an educational product, a notebook of activities, which was structure to allow during its implementation, students can conduct historical and/or Mathematics research, therefore, we present the procedures for realization of each construction, followed at some moments by original solution of the work. At the same time, we encourage students to investigate/reflect its construction (GeoGebra), in addition to making comparisons with the solution Mascheroni. This notebook was applied to two classes of the course of Didactics of Mathematics I (MAT0367) Course in Mathematics UFRN in 2014. Knowing the existence of some unfavorable arguments regarding the use of history of mathematics, such as loss of time, it was found that this factor can be mitigated with the aid of computational resource, because we can make checks using only the dynamism of and software without repeating the construction. It is noteworthy that the minimized time does not mean loss of reflection or maturation of ideas, when we adopted the process of historical and/or Mathematics Investigation

The historical investigation tasks were planned and applied in the classroom, focusing on functional thought. The results obtained during the experience were described and evaluated based on authors who support the assumption of investigation and history as an alternative to the learning of mathematics. We emphasize that the material of analysis consisted of a work diary, audio recordings, questionnaires with testimony of the students involved, and, in addition, the assessment of the teacher of that subject. With regard to the mathematical content, the study was restricted to the concept of function, forms of representation and notation. It was evident that students showed great improvement with regard to the necessary formalization of the mathematical contents which were focused on, and to the active involvement of the students at different stages of the study. We can affirm that the completed study certainly represents significant contributions to an approach in the teaching-learning of functional thought / Neste estudo analisamos o desenvolvimento de uma experi?ncia de ensino, envolvendo alunos da licenciatura em matem?tica da UFRN, que tomou como base a hist?ria da matem?tica e as investiga??es matem?ticas com vistas a contribuir para a melhoria do ensino-aprendizagem da matem?tica. Foram planejadas e aplicadas tarefas de investiga??o hist?rica em sala de aula enfocando o pensamento funcional. Descrevemos e avaliamos os resultados obtidos durante a experi?ncia, ? luz de autores que sustentam o pressuposto da investiga??o e da hist?ria como alternativa para a aprendizagem da matem?tica. Destacamos que o material de an?lise constituiu-se de di?rio de campo, grava??es em ?udio, question?rios com depoimento dos alunos envolvidos, bem como da avalia??o do professor da disciplina. Em rela??o ao conte?do matem?tico, o estudo se limitou ao conceito de fun??o, formas de representa??o e nota??o. Ficou evidenciado que os alunos avan?aram bastante no que se refere ? formaliza??o necess?ria dos conte?dos matem?ticos focalizados, como tamb?m, ao envolvimento ativo dos alunos nas diferentes etapas do estudo. Podemos afirmar que o estudo desenvolvido certamente representa contribui??es para uma abordagem significativa no ensino-aprendizagem do pensamento funcional

For the development of this work, we rely on the Design Experiment. Within this theoretical contribution: we make the Theoretical Methodological basis of this research and establish the teaching framework learning logarithms from the analysis of a reference book on the theme for teacher training, two collections of textbooks adopted by the school that hosts this research And dissertations on the teaching of the subject and a conceptual study of the logarithm mathematical object. Second, we used the research scenarios associated with classroom research to elaborate a set of tasks that facilitated the introduction of the logarithms theme. This set we tested and reworked in a cycle of applications and applied as a tool for collecting the textual productions of the research participants in a second cycle. The data analyzed with the support of Theory of Registers of Semiotic Representation - TRRS indicate the scope of several properties of the logarithms from the tasks proposed to the participants as well as their adherence to the proposed research. The resulting product of this dissertation is a didactic guide for teachers containing reflections on the theoretical contribution of this research together with a set of tasks for the learning of logarithms elaborated from the data analysis of the present work / Esta pesquisa discute produ??es escritas de estudantes do Ensino M?dio acerca de propriedades de logaritmos em um ambiente investigativo. Para o desenvolvimento deste trabalho apoiamo-nos no Experimento de design.

Geometrias n?o-euclidianas como anomalias: implica??es para o ensino de geometria e medidas

Nascimento, Anna Karla Silva do 25 July 2013 (has links)
Made available in DSpace on 2014-12-17T15:05:03Z (GMT). No. of bitstreams: 1 AnnaKSN_DISSERT.pdf: 2228892 bytes, checksum: fc6b8553824d405981f02c90c321636a (MD5) Previous issue date: 2013-07-25 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / This present research the aim to show to the reader the Geometry non-Euclidean while anomaly indicating the pedagogical implications and then propose a sequence of activities, divided into three blocks which show the relationship of Euclidean geometry with non-Euclidean, taking the Euclidean with respect to analysis of the anomaly in non-Euclidean. PPGECNM is tied to the line of research of History, Philosophy and Sociology of Science in the Teaching of Natural Sciences and Mathematics. Treat so on Euclid of Alexandria, his most famous work The Elements and moreover, emphasize the Fifth Postulate of Euclid, particularly the difficulties (which lasted several centuries) that mathematicians have to understand him. Until the eighteenth century, three mathematicians: Lobachevsky (1793 - 1856), Bolyai (1775 - 1856) and Gauss (1777-1855) was convinced that this axiom was correct and that there was another geometry (anomalous) as consistent as the Euclid, but that did not adapt into their parameters. It is attributed to the emergence of these three non-Euclidean geometry. For the course methodology we started with some bibliographical definitions about anomalies, after we ve featured so that our definition are better understood by the readers and then only deal geometries non-Euclidean (Hyperbolic Geometry, Spherical Geometry and Taxicab Geometry) confronting them with the Euclidean to analyze the anomalies existing in non-Euclidean geometries and observe its importance to the teaching. After this characterization follows the empirical part of the proposal which consisted the application of three blocks of activities in search of pedagogical implications of anomaly. The first on parallel lines, the second on study of triangles and the third on the shortest distance between two points. These blocks offer a work with basic elements of geometry from a historical and investigative study of geometries non-Euclidean while anomaly so the concept is understood along with it s properties without necessarily be linked to the image of the geometric elements and thus expanding or adapting to other references. For example, the block applied on the second day of activities that provides extend the result of the sum of the internal angles of any triangle, to realize that is not always 180? (only when Euclid is a reference that this conclusion can be drawn) / A presente pesquisa tem como objetivo mostrar ao leitor a Geometria n?o-euclidiana enquanto anomalia indicando as implica??es pedag?gicas e em seguida propor uma sequ?ncia de atividades distribu?das em tr?s blocos, as quais mostram a rela??o da geometria euclidiana com a n?o-euclidiana, tomando a euclidiana com refer?ncia para an?lise da anomalia na n?o-euclidiana. Est? vinculada ao Programa de P?s-Gradua??o em Ensino de Ci?ncias Naturais e Matem?tica da Universidade Federal do Rio Grande do Norte na linha de pesquisa de Hist?ria, Filosofia e Sociologia da Ci?ncia no Ensino de Ci?ncias Naturais e da Matem?tica. Aborda aspectos relativos a Euclides de Alexandria, bem como sobre a sua obra mais famosa Os Elementos e, al?m disso, enfatiza o Quinto Postulado de Euclides, sobretudo ?s dificuldades (que perduraram v?rios s?culos) que os matem?ticos tinham em compreend?-lo. At? que, no s?culo XVIII, tr?s matem?ticos: Lobachevsky (1793 1856), Bolyai (1775 1856) e Gauss (1777-1855) foram convencidos que tal axioma era correto e que existia uma outra geometria (an?mala) t?o consistente quanto a de Euclides, mas que n?o se enquadrava em seus par?metros. ? atribu?da a esses tr?s o advento da geometria n?o-euclidiana. Para o percurso metodol?gico s?o pontuadas algumas defini??es de car?ter bibliogr?fico sobre as anomalias, depois elas s?o caracterizadas, para que a defini??o seja melhor compreendida pelo leitor e, em seguida,s?o destacadas as geometrias n?o-euclidianas (Geometria Hiperb?lica, Geometria Esf?rica e a Geometria do Motorista de T?xi) confrontando-as com a euclidiana para que sejam analisadas as anomalias existentes nas geometrias n?o-euclidianas e observemos sua import?ncia ao ensino. Ap?s tal caracteriza??o segue-se a parte emp?rica da proposta que consistiu na aplica??o de tr?s blocos de atividades em busca de implica??es pedag?gicas de anomalia. O primeiro sobre as retas paralelas, o segundo sobre o estudo dos tri?ngulos e o terceiro sobre a menor dist?ncia entre dois pontos. Esses blocos oferecem um trabalho com elementos b?sicos da geometria a partir de um estudo hist?rico e investigativo das geometrias n?o-euclidianas enquanto anomalia de modo que o conceito seja compreendido juntamente com suas propriedades sem necessariamente estar vinculada a imagem dos elementos geom?tricos e, consequentemente, ampliando ou adaptando para outros referenciais. Por exemplo, o bloco aplicado no segundo dia de atividades proporciona que se amplie o resultado de soma dos ?ngulos internos de um tri?ngulo qualquer, passando a constatar que n?o ? sempre 180? (somente quando Euclides ? refer?ncia que esta conclus?o pode ser tirada)

Nesse sentido, foi realizada uma pesquisa qualitativa com duas fases: a primeira sendo te?rica e feita por meio de pesquisa do tipo bibliogr?fica e a segunda, com natureza mais pr?tica, caracterizando-se pela perspectiva da pesquisa a??o. Como resultado foi delineado um panorama hist?rico do conceito de Fun??o - com base na perspectiva de Youschkevitch (1976) - cujo conte?do foi refer?ncia para o desenvolvimento do Produto Educacional, composto por um Caderno de Atividades, aplicado a alunos da Educa??o B?sica, o qual aborda o conceito de Fun??o desenvolvido ao longo da hist?ria, usando como apoio o software Geogebra ? luz da IM. / This text describes a research in which guiding conceptions of the use of the History of Mathematics (HM) in the teaching of Function are presented, which resorts to the elements of the application of Information and Communication Technologies (ICT) along with the Mathematical Investigation (MI) in the classroom, constituting a Professional Master?s Degree dissertation whose aim is to propose an Activity Book based on the articulation between HM and ICT, through MI, which contributes to the teaching-learning process of Function. In this sense, a qualitative research was carried out in two phases: the first one of a theoretical type through a bibliographic research, and the second one on a more practical basis, characterized by the perspective of action research. As a result, a historical overview of the concept of Function was outlined based on Youschkevitch?s perspective (1976), whose content was a reference to the development of the Educational Product which is an Activity Book designed for students of Basic Education in which the concept of Function developed throughout history with the support of the use of Geogebra software is addressed under the light of MI.
