Firstly we checked the available mathematical knowledge sources and we did a complementary research about similar themes. We also checked the graduation and recognition of the teachers as professionals. We found in Tardif and collaborators the background for development of this research. In order to find out the answer for the research question, we applied a needs analysis with thirteen questions for sixteen teachers. According to the answers, we chose three questions for an interview with five of these teachers to becoming clear important points in their answers. The result gotten into the needs analysis shows that the main material used by these respondents is the didactic book and also the graduated Mathematics teachers that help them with their doubts. We also concluded that the knowledge valued by the respondents is the one that Tardif (2006) calls Experiential Knowledge, which comes from in their individual or group daily experiences / O objetivo desta pesquisa é investigar sobre fontes de saber matemático de um grupo de professores e professoras que lecionam nos anos iniciais do ensino fundamental (do primeiro ao quarto ano do ciclo I) em uma escola pública municipal paulista. Para isso, percorremos uma trajetória de investigação sobre as fontes de saber matemático disponíveis e procuramos fazer um levantamento de trabalhos sobre tema similar. Também estudamos sobre a formação e a profissionalização do professor. Buscamos o referencial para o desenvolvimento de nossa pesquisa em Tardif e colaboradores. Em busca de resposta à nossa questão de pesquisa, aplicamos um questionário para dezesseis professores, composto por treze questões, e realizamos entrevista com cinco desses professores, com três questões que julgamos que esclareceriam pontos importantes levantados a partir das respostas ao questionário. Ao analisarmos os dados obtidos por meio dos questionários e das entrevistas, verificamos que as fontes de saber mais utilizadas pelos sujeitos de nossa pesquisa são os livros didáticos e os colegas, incluindo os professores especialistas, com formação em Licenciatura em Matemática. Verificamos também que os saberes valorizados pelos sujeitos são os que Tardif (2006) chama de Saberes Experienciais, aqueles que emergem das experiências individuais ou coletivas no cotidiano escolar

It intends to bring contribution for the initial formation improvement of the initial series teachers, being the trainee a reference point. The perspective is to identify Mathematic knowledge that this future teacher purchases during your formation at the University and at the school that the stage was developed. Contacting a University that offers the Pedagogy course, was selected a student that realized the supervised stage, indicated by the professor of this subject. The teacher of the discipline 'Mathematics Content and Methodology' from the Pedagogy Course and the regent teacher with whom was realized the stage in the Basic Education school were part of the research. It was investigated the proposals of the educational project and the Supervised Stage Manual related to the formation of a critic, investigative and reflexive professional on Mathematics contents; the opportunities for investigation, reflection and critic moments about Mathematics teaching and learning process on stage activities and practices and the regent teacher's contribution to the construction of a educational mathematics knowledge for the future teacher of initial series. Based on the research of Tardif (2002) about teacher knowledge and professional formation, Pimenta (2008) about stage and teaching, Curi (2004) about initial series teachers formation, Shulman (2004) about knowledge base categories for the teacher and Alarcão (2008) about the reflection in teaching. The data were obtained through documentary analysis and half-structured with two teachers of a Pedagogy course, a student that realized the stage, and the regent teacher of the school. The distance between the university and the school, pointed by several researches, prevails in this investigation, and it's up to the trainee the responsibility to realize his stage, according to the documents of institution and guidance of the regent teacher. This responsibility should be discussed, reflected and investigated by the formation agents / O presente trabalho tem como objetivo investigar a formação de conhecimentos escolares matemáticos das séries iniciais nas atividades de Estágio Supervisionado e Prática como componente curricular. Pretende trazer contribuição para o aperfeiçoamento da formação inicial de professores das séries iniciais. A perspectiva é a de identificar possíveis contribuições para a formação de conhecimentos escolares matemáticos para o futuro professor durante sua formação na universidade, no curso de Pedagogia, e na escola onde desenvolve seu estágio, por meio de um estudo de caso. A partir de contato com uma Universidade que oferece Curso de Pedagogia, foi selecionada uma aluna que realizou a disciplina de Estágio Supervisionado, indicada pela professora dessa disciplina. O professor da disciplina de Conteúdo e Metodologia de Matemática do Curso de Pedagogia e a professora regente com a qual foi realizado o estágio na escola de Educação Básica também fizeram parte da pesquisa. Investigou-se as propostas do Projeto Pedagógico e do Manual de Estágio Supervisionado relacionadas à formação de um profissional crítico, investigativo e reflexivo em relação aos conteúdos escolares matemáticos; as oportunidades de momentos de investigação, reflexão e crítica sobre o processo de ensino e aprendizagem da Matemática nas atividades de estágio e prática e as contribuições da professora regente para a construção do conhecimento escolar matemático da futura professora das séries iniciais. Fundamenta-se nas pesquisas de Tardif (2002) sobre saberes docentes e formação profissional, Pimenta (2008) sobre estágio e docência, Curi (2004) sobre a formação de professores das séries iniciais, Shulman (2004) sobre categorias da base de conhecimentos para o professor e Alarcão (2008) sobre a reflexão na docência. Os dados foram obtidos por meio de análise documental e entrevistas semi-estruturadas com duas professoras de um Curso de Pedagogia, uma aluna que realizou estágio e a professora regente da escola campo de estágio. O distanciamento existente entre a universidade e a escola, apontado por diversas pesquisas, prevalece nessa investigação, cabendo à estagiária a responsabilidade por realizar seu estágio, segundo o que consta nos documentos da instituição e orientações da professora regente. Responsabilidade que deveria ser dialogada, refletida e investigada pelos agentes formadores

This study establishes a framework for the practice and the acquisition of mathematical knowledge. The natures of mathematics and rituals/ritual-like activities are examined compared and contrasted. Using a four-fold typology of core features, surface features, content features and functions of mathematics it is established that the nature of mathematics, its practice and the acquisition is typologically similar to that of rituals/ ritual-like activities. The practice of mathematics and its acquisition can hence be metaphorically compared to that of rituals/ritual-like activities and be enriched by the latter. A case study was conducted using the ritual metaphor at two levels to introduce and teach a topic within the current year eleven West Australian Geometry and Trigonometry course. In the first level, instructional materials were written using a ritual-like mentor-exemplar, exposition, replicate and extrapolate model (through the use of specially organised examples and exercises) based on the approaches of several mathematics text book authors as they attempted to introduce a topic new to the West Australian mathematics curriculum. / In the second level, the classroom instruction was organised using a ritual-like pattern with direct exemplar mentoring and exposition by the teacher followed by replication and extrapolation from the students. Embedded within this ritual-like process was the personal (and communal) engagement with each student vis-a-vis the establishment of the relationships between the referent concepts, procedures and skills. This resulted in the emergence of solution behaviours appropriate to specific tasks imitating and extrapolating the mentored solution behaviours of the teacher. In determining the extent to which the instruction, mentoring and acquisition was successful, each student's solution 'behaviour was compared "topographically" with the expected solution behaviour for the task at various critical points to determine the degree of congruence. Marks were allocated for congruence (or removed for incongruence), hence a percentage of congruence was established. The ritual-like model for the teaching and acquisition of mathematical knowledge required agreement with all stake-holders as to the purpose of the activity, expert knowledge on the part of the teacher, and within a classroom context requires students to possess similar levels of prerequisite mathematical knowledge. / This agreement and the presence of an expert practitioner, provides the affirmation and security that is inherent in the practice of rituals. The study concluded that there is evidence to suggest that some aspects of mathematical ability are wired into the cognitive structures of human beings providing support to the hypothesis that some aspects of mathematics are discovered rather than created. The physical origin of mathematical abilities and activities was one of the factors used in this study to establish an isomorphism between the nature and practice of mathematics with that of rituals. This isomorphism provides the teaching and learning of mathematics with a more robust framework that is more attuned to the social nature of human beings. The ritual metaphor for the teaching and learning of mathematics can then be used as a framework to determine the relative adequacies of mathematics curricula, mathematics textbooks and teaching approaches.

In this dissertation, I propose that network theory offers a useful frame for informing mathematics education. Mathematical understanding, like the discipline of formal mathematics within which it is subsumed, possesses attributes characteristic of complex systems. As the techniques of network theorists are often used to explore such forms, a network model provides a novel and productive way to interpret individual comprehension of mathematics. A network structure for mathematical understanding can be found in cognitive mechanisms presented in the theory of embodied mathematics described by Lakoff and Nez. Specifically, conceptual domains are taken as the nodes of a network and conceptual metaphors as the connections among them. Examination of this metaphoric network of mathematics reveals the scale-free topology common to complex systems. Patterns of connectivity in a network determine its dynamic behavior. Scale-free systems like mathematical understanding are inherently vulnerable, for cascading failures, where misunderstanding one concept can lead to the failure of many other ideas, may occur. Adding more connections to the metaphoric network decreases the likelihood of such a collapse in comprehension. I suggest that an individuals mathematical understanding may be made more robust by ensuring each concept is developed using metaphoric links that supply patterns of thought from a variety of domains. Ways of making this a focus of classroom instruction are put forth, as are implications for curriculum and professional development. A need for more knowledge of metaphoric connections in mathematics is highlighted. To exemplify how such research might be carried out, and with the intent of substantiating ideas presented in this dissertation, I explore a small part of the proposed metaphoric network around the concept of EXPONENTIATION. Using collaborative discussion, individual interviews and literature, a search for representations that provide varied ways of making sense of EXPONENTIATION is carried out. Examination of the physical and mathematical roots of these conceptualizations leads to the identification of domains that can be linked to EXPONENTIATION.

This paper examines the mathematical knowledge for teaching (MKT) in Indonesia, specifically in school geometry content. A translated and adapted version of the MKT measures developed by the Learning Mathematics for Teaching (LMT) project was administered to 210 Indonesian primary and junior high teachers. Psychometric analyses revealed that items related to classification of quadrilaterals were difficult for these teachers. Further interactions with teachers in a professional development setting confirmed that teachers held a set of exclusive definitions of quadrilaterals.

Mathematical modelling problems are embedded in written, representational, and graphic text. For students to actively engage in the mathematical-modelling process, they require literacy. Of critical importance is the comprehension of the problems' text information, data, and goals. This design-research study investigated the application of top-level structuring; a literary, organisational, structuring strategy, to mathematical-modelling problems. The research documents how students' mathematical modelling was changed when two classes of Year 4 students were shown, through a series of lessons, how to apply top-level structure to two scientifically-based, mathematical-modelling problems. The methodology used a design-based research approach, which included five phases. During Phase One, consultations took place with the principal and participant teachers. As well, information on student numeracy and literacy skills was gathered from the Queensland Year 3 'Aspects of Numeracy' and 'Aspects of Literacy' tests. Phase Two was the initial implementation of top-level structure with one class of students. In Phase Three, the first mathematical-modelling problem was implemented with the two Year 4 classes. Data was collected through video and audio taping, student work samples, teacher and researcher observations, and student presentations. During Phase Four, the top-level structure strategy was implemented with the second Year 4 class. In Phase Five, the second mathematical-modelling problem was investigated by both classes, and data was again collected through video and audio taping, student work samples, teacher and researcher observations, and student presentations. The key finding was that top-level structure had a positive impact on students' mathematical modelling. Students were more focussed on mathematising, acquired key mathematical knowledge, and used high-level, mathematically-based peer questioning and responses after top-level structure instruction. This research is timely and pertinent to the needs of mathematics education today because of its recognition of the need for mathematical literacy. It reflects international concerns on the need for more research in problem solving. It is applicable to real-world problem solving because mathematical-modelling problems are focussed in real-world situations. Finally, it investigates the role literacy plays in the problem-solving process.

Orientador: Dr. Alessandro Jacques Ribeiro / Tese (doutorado) - Universidade Federal do ABC, Programa de Pós-Graduação em Neurociência e Cognição, 2017. / O presente estudo preocupou-se em investigar se e como o conceito anel de polinomios e (re)construido por professores de Matematica que lecionam na Educacao Basica. Neste estudo, discutiu-se a importancia da construcao de conceitos matematicos, tendo por um lado a contribuicao do campo da ciencia cognitiva, principalmente os trabalhos Anna Sfard, e as recentes pesquisas sobre conhecimento matematico para o ensino, na area de Educacao Matematica, utilizando, essencialmente os trabalhos de Debora Ball, Jose Carrillo e seus colaboradores. Adotou-se a metodologia de pesquisa de natureza quantiqualitativa e o processo de coleta de dados se desenvolveu por meio de encontros do Curso de Extensao \O Ensino de Algebra para a Educacao Basica., ministrado na Universidade Federal do ABC, no estado de Sao Paulo, e conduzido por professores universitarios integrantes do programa Observatorio da Educacao. Para a producao de dados da pesquisa, utilizou-se como instrumentos metodologicos os questionarios e os registros escritos, elaborados/produzidos pelos professores-participantes da pesquisa durante os encontros do referido curso. A partir da analise dos dados, os resultados da investigacao apontam para a necessidade de promover acoes que possam ampliar e aprofundar o conhecimento especifico matematico desses professores, dado que ninguem pode ensinar o que nao sabe. Tambem evidenciamos a necessidade de um (re)pensar sobre o ensino de polinomios, uma vez que tal a analise dos dados realizados revelou que os professores desconhecem procedimentos para se operar com polinomios. Espera-se com este estudo chamar a atencao das politicas publicas para a necessidade de investimento na formacao continuada dos professores de matematica e, por conseguinte, na valorizacao da carreira docente. / This study intended to investigate mathematical knowledge building for teaching the concept of polynomial with Math teachers in Basic Education. In this study, the importance of building mathematical concepts was discussed, considering contributions from the cognitive sciences field, particularly Anna Sfard`s works, and recent research on mathematical knowledge for Algebra teaching from the Math Education field, using essentially works by Ball, Carrillo and their collaborators. A qualitative-quantitative approach for our research design was adopted, and the data gathering process was developed from meetings of a Extracurricular Course on Algebra Teaching for Basic Education, offered at the Federal University of ABC, in São Paulo State, conducted by university professors from the Education Observatory program. In producing the research data, questionnaires and written registers were used, elaborated by research participants themselves during the Course`s meetings. From the analysis of the data, the research results point to the need to promote actions that can broaden and deepen the specific mathematical knowledge of these teachers, given that no one can teach what they do not know. We also show the need for a new thinking about the teaching of polynomials, once such analysis of the data revealed that teachers are not aware of procedures to operate with polynomials. It is hoped that this study will draw the attention of public policies to the need for investment in the continuing education of mathematics teachers and, consequently, in the valorization of the teaching career.

The study is based on the constructivist sociointeractionist approach to teaching Mathematics and it constitutes, in itself, a methodological intervention with the teachers-trainees engaged in the Professional Qualification Program in Basic Education of the Federal University of Rio Grande do Norte. The foundations of the study were found in investigations of researchers who had carried out studies on the construction of numerical writing, showing, for instance, that the construction process of ideas and procedures involved in groupings and changes to base 10 take a lot longer to be accomplished than one can imagine. A set of activities was then elaborated which could not only contribute to the acquisition of contents but that could also make the teachers-trainees reflect upon their teaching practices in the classroom so that in this way they will be able to elaborate more consistent didactic approaches, taking into consideration the previous knowledge of the students and also some obstacles that often appear along the way. Even when teachers have access to the most appropriate dicactic resources, the lack of knowledge of the content and of the real meaning of that content make the Decimal Numbering System, a subject of fundamental importance, be taught most times in a mechanical way. The analisys of the discussions and behaviours of the teachers-trainees during the activities reavealed that they made them reflect upon their current practices in the classroom and that, as a whole, the aims of each of the activities carried out with the teachers-trainers were reached / O presente estudo tem como quest?o central identificar o conhecimento epistemol?gico que os professores-alunos possuem a respeito das caracter?sticas (propriedades) do sistema de numera??o decimal, e tem como finalidade oferecer uma contribui??o para a pr?tica pedag?gica dos professores que atuam nas turmas de Ciclo B?sico de Alfabetiza??o, tanto no que se refere ? aquisi??o de conte?dos quanto ao aprimoramento de conhecimentos que os auxiliem na elabora??o de estrat?gias adequadas para o trabalho com o Sistema de Numera??o Decimal em sala de aula. O estudo est? baseado na proposta construtivista sociointeracionista para o ensino da Matem?tica e se constitui numa interven??o metodol?gica, com os professores-alunos ligados ao Programa de Qualifica??o Profissional para a Educa??o B?sica da Universidade Federal do Rio Grande do Norte. Buscaram-se fontes de sustenta??o em investiga??es de pesquisadores que realizaram estudos sobre a constru??o das escritas num?ricas, mostrando, por exemplo, que o processo de constru??o das id?ias e procedimentos envolvidos nos agrupamentos e trocas na base 10 leva muito mais tempo para ser realizado do que se pode imaginar. Foi elaborado um conjunto de atividades as quais pudessem n?o s? contribuir para a aquisi??o de conte?dos, mas fizessem os professores-alunos refletir sobre suas pr?ticas em sala de aula, para que, assim, eles pudessem elaborar propostas did?ticas mais consistentes, levando em conta os conhecimentos pr?vios dos alunos e alguns obst?culos que se interp?em nessa trajet?ria. Mesmo o professor dispondo dos mais apropriados recursos did?ticos, a falta de dom?nio do conte?do, do real significado desse conte?do, faz com que o Sistema de Numera??o Decimal, tema de fundamental import?ncia, seja ensinado, na maioria das vezes, de forma mec?nica. A an?lise das discuss?es e o comportamento dos professores-alunos durante a realiza??o das atividades revelaram que estas provocaram reflex?es sobre as pr?ticas de sala de aula como tamb?m que, de modo geral, foram atingidos os objetivos propostos em cada atividade realizada com os professores-alunos

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / In this text are presented results of a research whose objective was analyze the appropriations of the intuitive method of Pestalozzi for the teaching of elementary mathematical knowledge in Brazilian periodicals of late of XIX and early of XX centuries. The theoretical contribution came from the use of Chartier (2003) to talk about appropriation, Valente (2015) about the elementary mathematical knowledge, Ragazzini (2001) about historical sources and Pestalozzi (1889, 2003) aiming an understanding about the intuitive method. In reading the works of Pestalozzi it was identified in relation the intuitive method started of elements of number, form and word, aiming the development of the child’s faculties or capacities that he had intuition as a foundation, and was based on perception, observation, use of the senses, in the graduality of teaching and sought to assist in the development of the child as a human person. The resources used Brazilian periodicals of late of XIX and early of XX centuries found in the digital repository of UFSC and that had some reference to Pestalozzi, method or some the principles. As results, can be emphasize a circulation of Pestalozzi in these periodicals, since it was referenced in publications of eight Brazilian states: Alagoas, Amazonas, Bahia, Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Norte and São Paulo. To indentify appropriation, understood as use or interpretation, were presented at a first moment those that in the articles had explicit references to Pestalozzi, and at a second moment, the articles that brought the intuitive method or some the principles. It is also worth noting that in the periodical Pestalozzi was pointed out as a forerunner of modern pedagogy, active school, natural education, and culture of the senses etc, all this refers to the intuitive method. He was also taken as an example of master and authority in Education. In relation to the elementary mathematical knowledge, were identified appropriation about the contents of fractions, count, sum and calculations called elementary arithmetical knowledge, geometric solids and drawing called elementary geometric knowledge. It is also emphasize that for the application of method intuitive, the elementary mathematical knowledge were indicated objects such as: Parker Letters, mechanical counters and geometric solids. / Este trabalho é resultado de uma pesquisa que teve por objetivo analisar apropriações dos princípios do método intuitivo de Pestalozzi, para o ensino de saberes elementares matemáticos em periódicos brasileiros do final do século XIX e início do século XX. Como fundamentação teórica para os principais conceitos foram utilizados Chartier (2003), para falar sobre apropriação, Valente (2015), para os saberes elementares matemáticos, Ragazzini (2001), a respeito de fontes históricas e Pestalozzi (1889, 2003), visando a um entendimento sobre o método intuitivo. Na leitura das obras de Pestalozzi foi identificado, em relação ao método intuitivo, que o mesmo partia dos elementos do número, forma e palavra e objetivava o desenvolvimento das faculdades ou capacidades da criança e que tinha a intuição como fundamento, e era pautado na percepção, observação, no uso dos sentidos, na gradação do ensino e buscava auxiliar no desenvolvimento da criança como pessoa humana. Como fontes forma utilizados periódicos brasileiros do final do século XIX e início do século XX encontrados no repositório digital da UFSC e que apresentavam alguma referência a Pestalozzi, ao método ou a pelo menos um de seus princípios. Como resultados, pode-se enfatizar uma circulação de Pestalozzi nesses periódicos, uma vez que ele foi referenciado em publicações de oito estados brasileiros: Alagoas, Amazonas, Bahia, Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Norte e São Paulo. Para identificar apropriação, entendida como uso ou interpretação, foram apresentadas em um primeiro momento aquelas que nos artigos tinham referências explícitas a Pestalozzi, e em um segundo, os artigos que traziam o método intuitivo ou um de seus princípios. Destaca-se também que, nos periódicos, Pestalozzi foi apontado como um precursor da pedagogia moderna, da escola ativa, da educação natural, da cultura dos sentidos etc., tudo isso remete ao método intuitivo. Além disso, ele também foi tido como exemplo de mestre e autoridade no que se refere à Educação. Em relação aos saberes elementares matemáticos foram identificadas apropriações acerca dos conteúdos fração, contagem, soma e cálculo denominados de saberes elementares aritméticos, e sólidos geométricos e desenho chamados de saberes elementares geométricos. Ressalta-se ainda, que para aplicação do método intuitivo aos saberes matemáticos foram indicados objetos como: cartas de Parker, contadores mecânicos e sólidos geométricos.
