Com este trabalho pretendo compreender o papel das histórias com matemática na motivação dos alunos durante a resolução de tarefas matemáticas, partindo das seguintes questões de investigação: a) Qual a relação que os alunos estabelecem com tarefas matemáticas construídas a partir de modelos matemáticos presentes em histórias? b) Que tipo de conhecimentos matemáticos surgem quando os alunos resolvem tarefas construídas a partir de um modelo matemático presente numa história? c) Como se desenvolve a comunicação matemática dos alunos quando se utilizam tarefas construídas a partir de modelos existentes em histórias? O trabalho foi realizado com uma turma de 2º e 3º anos de escolaridade, que têm desenvolvido com a professora cooperante, ao longo do tempo, um excelente trabalho na disciplina de matemática. Para o desenvolvimento deste estudo optei por utilizar uma metodologia de investigação qualitativa, como investigadora participante. Saliento, ainda, que a recolha de dados ocorreu ao longo do estágio da Unidade Curricular: Prática de Ensino Supervisionado. Durante um total de onze aulas, a análise de dados baseou-se em registos de vídeo, produções individuais dos alunos, produções dos alunos em grande grupo, e ainda na observação das interações geradas durante a análise e discussão das estratégias apresentadas pelos alunos, durante a realização das tarefas. As tarefas matemáticas apresentadas aos alunos, para o desenvolvimento deste estudo, surgiram de modelos matemáticos presentes no conto “Ainda não estão contentes?”, inserido no livro Conto Contigo, de António Torrado. Durante a realização das tarefas foi possível desenvolver conceitos que se inserem nos temas matemáticos de Números e Operações e Medida. Os resultados deste trabalho, poderão ser desenvolvidos no futuro, partindo de outros estudos e utilizando diferentes modelos matemáticos, outras histórias, outros contextos educativos, de modo a que seja possível provar que a matemática não tem de ser vista como uma disciplina difícil e angustiante para os alunos, porque existe sempre a hipótese de através de histórias, envolver os alunos nas suas aprendizagens, motivando-os para realizar tarefas matemáticas e desenvolver conhecimento matemático.

Compreender as características e as formas do jornalismo utilitário é o objetivo desta pesquisa. Conhecido também como jornalismo de serviço ou de interesse público, trata-se de um gênero jornalístico a partir do momento em que as mensagens se organizam em modalidades, agregando em seu discurso finalidades próprias, orientação e guia. Para a sua compreensão, realizou-se um estudo bibliográfico com interesse particular de entender as propriedades do jornalismo utilitário, bem como a sua identificação enquanto gênero. No segundo momento, realizou-se uma pesquisa qualitativa, utilizando a técnica de análise documental em jornais brasileiros de referência. Ao final, verificou-se que a evolução das formas e conteúdo dá-se em três fases não excludentes: 1. A publicação dos serviços práticos no início da imprensa do Brasil; 2. A produção dos conselhos, em destaque no século XX; 3. O gênero utilitário como complemento de outros gêneros, prática consolidada no século XIX. E por fim, com proposta didática, a tese apresenta uma taxionomia para o gênero utilitário.

A imprensa brasileira nasceu tardiamente, 276 anos após o início da ocupação da colônia americana pela Coroa portuguesa. Investigando as singularidades desse processo na região Nordeste, pretende-se resgatar a gênese das atividades tipográficas no Maranhão, cujo marco é o jornal O Conciliador do Maranhão, que circulou entre novembro de 1821 e julho de 1823. O objetivo é identificar os fatores socioculturais que explicam o retardamento da imprensa no Estado. Para tanto, foi realizada uma pesquisa histórica adotando dupla estratégia metodológica: a) qualitativa: destinada a compreender as circunstâncias que contribuíram para delongar a chegada da imprensa à capital maranhense, condicionando a natureza da produção jornalística nascente; b) quantitativa: visando reconstituir o perfil jornalístico, a política editorial e a estrutura morfológica do jornal pioneiro, através da análise do conteúdo manifesto de uma amostra daquele periódico.(AU)

Essa pesquisa bibliográfica e empírica teve como objetivo analisar livros didáticos de História elaborados para 6ªs séries do ensino fundamental utilizados em uma escola estadual de nome fictício Monte Alto, situada no Extremo Leste de São Paulo e uma escola municipal de nome fictício Morro da Cruz localizada em um bairro da Zona Leste de São Paulo. Durante a construção desse trabalho, pretendeu-se fazer uma leitura de manuais escolares de História, objetivando compreender como a invasão holandesa é abordada nos materiais didáticos. Além dos materiais das escolas estadual e municipal, foram analisados três compêndios do século XIX cujos autores são José Inácio de Abreu e Lima, Francisco Adolfo de Varnhagen e Joaquim Manoel de Macedo, também materiais didáticos de dois autores do século XX, Joaquim Silva e Sérgio Buarque de Holanda. Buscou-se, ainda, evidenciar qual trajetória o livro didático percorre da produção editorial até a distribuição aos destinatários finais, alunos e professores, a partir das contribuições de Circe Bittencourt, Kazumi Munakata e outros referenciais teóricos. Em suma, esse trabalho tencionou responder como os textos didáticos abordam a invasão holandesa e como esse tema é apropriado pelo alunado e docentes. Por meio de estudo de caso, foram analisadas as representações de dois grupos específicos alunos e professores da escola Monte Alto e da escola Morro da Cruz sobre a invasão holandesa, à luz das orientações teóricas de Roger Chartier.

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 propóposito 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

In this work we present the description and analysis of the clitics collocation patterns in prepositional infinitive sentences within the Brazilian writing in the centuries XIX and XX. The corpus in analysis is comprised of letters of newspaper readers and newspaper writers, as well as of advertisements (ads) taken from Brazilian newspapers from different regions / states – Rio de Janeiro, Bahia, Ceará and Pernambuco – and written in the Centuries XIX and XX. They belong to the common minimum corpus of the project named Projeto para a História do Português Brasileiro (PHPB or Project to the History of the Brazilian Portuguese, in English). Its analysis is based on theoreticalmethodological postulates of the Theory of Variation and Change (WEINREICH; LABOV; HERZOG, 1968[2006]; LABOV, 1972[2008]); on the Theory of Principles and Parameters (CHOMSKY, 1981, 1986) and on the model of Grammar Competition (KROCH, 1989; 2001). By trying to articulate those presuppositions from both the theories we present a proposition of theoretical interface between the Variation Theory and the Grammar one. Concerning the empirical results achieved by means of this research, we could figure that, in the context in which there were prepositional infinitive sentences, the most significant independent variable to the occurrence of the proclisis is the type of preposition that comes before the verb in the infinitive. Before that, we found out that there are prepositions which strongly direct the proclisis, as it is the case of the prepositions in Portuguese sem, por, de and para, with all of them presenting Relative Weights over 0,52. Another important result is the one attested in the data referring the state of Rio de Janeiro (RJ). This state is the only one of the sample which is located in the Southeastern region and also presents itself as the main proclisis conditioner amongst the localities pertaining to the sample. In order to explain those results, we raised the hypothesis that the proclisis implementation may be more advanced in the Southeastern than in the Northeastern Brazil, however that hypothesis must be confirmed or refuted in future works. We also present, in this work, a theoretical explanation about the clitics colocation in prepositional infinitive sentences within the Brazilian writing in the XIX and XX centuries. The theoretical explanation we found to interpret the achieved results associates Magro’s proposition (2005), regarding the existence of prepositions occupying the nucleus PP and the existence of prepositions which can play the role of a completer and occupy the nucleus CP, according to Galves (2000; 2001), regarding the existent relation between the clitic colocation and the association of traits-phi to the functional categories COMP, Tense and Person. Our proposition is that the occurrence of prepositions which occupy the nucleus CP causes changes in the values attributed to the traits-phi and to the strong Vtraits in the functional categories COMP, Tense and Person. Thus, we defend that proclisis in Brazilian Portuguese (BP) is derived from the movement of the verb to the functional category tense in which there is the association of traits +V and traits +AGR, what legitimates the proclisis according to Galves´s proposition (2000; 2001).

The present dissertation focuses on specific problems in the educational context: challenges in the construction of historical narratives for pedagogical use as well as the difficult task of using them in the classroom. In this context, we seek to work in teacher training for insertion of History and Philosophy of Science (HPS) in classroom, and historical narratives become mediation elements to advance the dialogue with this specific audience. This initiative is in line with a recurring concern: one of the main challenges related to the didactic transposition of HFC would be the lack of teacher preparation. Historical contents and Nature of Science are still absent in classrooms. Insecurity and lack of knowledge by teachers are often mentioned as factors that contribute to this situation. It is important, therefore, that teachers (active and in training) take part in discussions concerning the inclusion of HPS in classroom. It is relevant that they know examples of historic-philosophical didactic proposals to address science and contents on science, develop skills to adapt them to their specific contexts and to develop their own proposals. It is believed that these issues are significant to undertake conscious initiatives to insert HPS in classrooms. It is considered that adapting educational proposals to particular educational contexts depends on understanding what these proposals indeed mean and how flexible they can be. In order to address these objectives, we elaborated an educational product, a didactic material focused on teacher training, which was used in an extension course at UFRN. The didactic material discusses the role of HPS in Education, Nature of Science and historiographical issues. It presents a series of dialogical activities on aspects of didactic transposition of HPS, especially those regarding historical narratives. A set of historicpedagogical texts on the History of Vacuum and Atmospheric Pressure is used as a mediation element in discussions. We address potential, possibilities and limitations historical narratives. To carry out the course, it was taken into account methodological concerns of so-called action research. There have been expected changes, modifications and effective actions in the own teacher training material in face of the experience of the researcher-lecturer in interactions with the participants of the course as well as in face of impressions reported by the participants. Developments in this direction have been incorporated into the teacher training material.

Este trabalho busca compreender o que é a Escola Brasileira de Clarineta a partir da segunda metade do século XX, tomando como referência a experiência e a história de vida de um clarinetista que participou de seu processo de consolidação, a saber, o Professor José Cardoso Botelho. Através da ferramenta da memória social, foi possível se obter dados que coligissem traços característicos desta escola, assim como informações históricas a partir dos quais os aspectos observados parecem ter surgido. A análise demonstrou, ainda, a forte presença do paradigma Mestre-Aprendiz na construção desta escola e como este se relaciona com a pedagogia, formação profissional e concepção ideológica na área das Práticas Interpretativas. A abordagem utilizada confia que a história de vida do personagem investigado envolve-se com a história da própria escola, de sorte que a sua trajetória é permeada por elementos constitutivos da identidade de ambos, o mestre e a escola a que pertence.

This work aims to study about the importance of cinema for cultural and professional training of teachers of Natural Sciences and Mathematics. The educational potential of cinema is emphasizing by different authors, which also reveal the teachers' training gap in this issue (media). In this study, we defend the audiovisual language of cinema as an integrating element of Arts and Science for cultural and professional training of teachers. This subject has been developed by different authors, in which the emphasis has been the importance of intelligent dialogue with the world. Specifically, the training of science teachers and mathematics, by the approach of Cinema in its formation, It envisions the possibility of minimizing the dichotomy between humanistic and scientific training, already much discussed by some researchers. Educational products contribute to an effective experience and reflection on the cultural and educational role of the Seventh Art. Considering the Cinema as a possible "bridge" between the two cultures (scientific culture and humanistic culture) and promoting ownership of audiovisual language in teacher training It was accomplished the I Exhibition - Cultural Spring: Cinema and Science Education in UFRN. The production of the booklet "Topics of History, Language and Art of Cinema for Science and Mathematics Teachers," and its application in a short course in the XXI National Symposium on Physics Teaching also aimed to contribute to the approximation of Science and Art in training teachers.

Based on the theoretical and methodological presuppositions of the theory of language variation and change (cf. WEINREICH; LABOV; HERZOG, 2006 [1968]), it is described and analyzed in this article the process of variation/change concerning the second person possessive pronouns in letters from readers of Brazilian newspapers from the XIX and XX centuries. These letters feature a portrait of the Brazilian press from the South (Santa Catarina), Southeast (Rio de Janeiro) and Northeast (Bahia and Rio Grande do Norte) regions in each century and are part of the Project for Brazilian Portuguese History‘s (PHPB) printed common minimal corpus. The point of departure of this work is the idea that the use of variant forms of expressing second person possessive pronouns – teu and seu – results from the interaction characterizing the varied social roles performed by the letters‘ senders. Arranging communicative units, which gather elements/features denoting time and space, conditioned and determined by socio-historical and cultural aspects, the readers‘ letters, turn out to be a promising research field under the light of this paper. More specifically, In the row of presented results in studies about the pronominal system in the diachroneity of/in Brazilian Portuguese (PB) (FARACO, 2002; LORENGIAN-PENKAL, 2007; CALLOU; LOPES, 2003; LOPES; DUARTE, 2003; MENON, 2005; ARDUIN; COELHO, 2006; LOPES, 2009; MARCOTULIO, 2010), the results featured in here point at different usages of the possessives, noticing the coexistence of the forms teu/tua and seu/sua strongly conditioned by the socio-discursive nature of the readers‘ letters in the course of the centuries and through different regions.

We seek, through this work, to understand the construction of the pirates’ images from the Golden Age of Piracy (late seventeenth through early eighteenth century) through the observation of the circulation of these images, which are not limited to one field of knowledge. We take into account the importance of the book “A General History of the robberies and murders of the most notorious pirates...” written by Charles Johnson for these constructions, not only literary, but also historiographical provided that the stories of pirates and piracy gained ground in historiography from the twentieth century on. We also seek to show that this historiographical space arises opposed to an apparent historiographical silence about these stories that lasts for about two centuries, related to a new way of writing history in the aesthetic regime, where it arises as a science through a poetics of knowledge, of which the philosopher Jacques Rancière helps us reflect. Lastly, reflecting upon how these images of pirates circulate nowadays, we seek to understand the historicity of the pirates’ images within that aesthetic regime based on some scenes of the film series Pirates of the Caribbean by Disney™.

Este relatório foi realizado no âmbito da Prática Pedagógica do Mestrado em 1.º e 2.º ciclos do Ensino Básico e integra duas componentes essenciais da mesma, a Reflexiva e a Investigativa. Na Componente Reflexiva podemos encontrar quatro reflexões: as duas primeiras relativas ao trabalho desenvolvido no 1.ºciclo, em turmas do 2.º e 3.ºano de escolaridade. Seguem-se as duas experiências em contexto de 2.ºciclo, ambas com turmas do 5.ºano de escolaridade, nos grupos de disciplinas Português/História e Geografia de Portugal e Matemática e Ciências Naturais. Destas reflexões emanam as principais dificuldades sentidas na prática pedagógica, bem como parte das aprendizagens realizadas. A Componente Investigativa, por sua vez, apresenta um estudo desenvolvido no 2.ºciclo do Ensino Básico, com a turma do 5.ºano de Matemática. O seu principal objetivo foi compreender de que forma uma professora, em contexto de formação inicial, desenvolveu a Comunicação Matemática dos alunos. Partindo deste objetivo, procurou-se conhecer as estratégias que a professora adotou nesse sentido, quais as dificuldades que decorreram da implementação dessas estratégias e qual a natureza do discurso que predominou na sala de aula. Deste modo, (i) o questionamento foi uma das estratégias mais utilizadas pela professora para promover momentos de discussão de ideias em sala de aula; (ii) as dificuldades da professora passaram por colocar questões de forma clara e objetiva e que exigissem ao aluno um nível de raciocínio elevado e (iii) o tipo de comunicação predominante foi a contributiva.

This research studies the relation between city and nature in the urbanity s plans from Natal RN, Brazil, during the 20th century. Investigates and analyses the main documents that bring environmental s ideas inside from the urbanity s plans of Natal; gives the historical and economical situation from the city in each period studied; features the urbanity s plans, using categories of analyses to comprehension of this instruments. Try to contribute in the bigger process of historical rescue of Natal, and stimulates new studies. It was used documental s research, and bibliographic material. It was identified four (04) kinds of plans: the ones that focus in health and aesthetic (1901, 1929, 1935) technology and science (1968), zoning and control (1974, 1984) and environment. The hints founded shows that environmental ideas were put inside of the plans by government demands, especially in 1994 s plan, almost always without popular contribution and without this population get understands its meanings and implications

The career of civil engineer Henrique de Novaes, a remarkable figure in the academic, technical and political fields, demonstrates its extensive and relevant work across Brazil in the first half of the twentieth century. It covered from the design of water supply and sewage works, road and rail transport networks, works against drought in the Northeast, hydroelectric and harbor facilities to the urbanization planning and architectural projects, which displays a systematic and multiple production. City and territory conformed to his fields of verification, practical and above all, transformation. The search for understanding of the inclusion of a social actor in this process thus contributes to the specific analysis of the doings of Henrique de Novaes, who graduated at Polytechnic School of Rio de Janeiro in 1906. From a polymorphic activity in different scales, one tries to figure how, through academic education or professional practice, urban history in Brazil can be told or built. The introduction of technological innovations matched the purposes of planning and urban sprawl, as well as met the specifications of regulation and institutionalization of public infrastructure services at the time. The overall plans proposed by the engineer thought of the city as a whole, interconnected to the structural networks. At the same time, the knowledge of a larger physical scale the territory bounces back in the urban in a relationship of reciprocity and completeness. The objective research, therefore, tries to understand the roles played by Henrique de Novaes s works and academic education in the accomplishment of systematic modernization of Brazilian urban space and territory, recovering a little known historical figure by current historiography. It is proposed, as methodological axis, that the study of this professional career configures itself as an essential element for understanding the idea of progress embodied in the technical studies and proposals for improvements and sanitation nationwide in the first half of the twentieth century . The primary sources for the construction of this analysis were technical articles in journals of the period ( Clube de Engenharia , Viação e Revista Brasileira de Engenharia ), and technical reports, government messages, newspaper articles published at the time, autobiographical reports and the engineer s verbal communications with relatives. The work is structured in three chapters: "Biographical traces, academic education and 'technical and political' activities" illustrates the initiation into the technical, public and political environment; Chapter 2, "Technique and territory" outlines his network understanding through sanitation and transport services; Chapter 3 "Technique and City" describes the influence of polytechnics knowledge on the propositions of modernization of cities; Finally, "Final Thoughts: An Evaluation," presents an overview of the affiliations and practice of an engineer in the different scales, and its contribution to the modernization of Brazilian urban and territorial space
