Sabendo da problemática existente nos cursos de graduação, como, por exemplo, a desarticulação entre teoria e prática, entre formação universitária e realidade escolar, deteve-se na seguinte questão: Quais são as perspectivas, expectativas e dificuldades que os futuros professores apresentam quando refletem sobre uma prática educativa utilizando planilhas eletrônicas na escola básica?. A pesquisa contou com a participação de dois futuros professores de Matemática da UNESP de Rio Claro. Foram realizados três encontros de planejamento, dez encontros de intervenção em uma escola pública, e dez encontros de reflexão, que ocorreram sempre após cada intervenção. Os licenciandos tiveram a oportunidade de expor suas idéias sobre as experiências realizadas e, a partir de uma análise à luz do referencial teórico, foram extraindo temas que se referem às suas expectativas, perspectivas e dificuldades. Entre eles, a gestão da sala de aula e a transposição de conteúdo, a complexidade da sala de aula, como eles percebem os alunos, as condições de trabalho na escola, ser professor e o uso de tecnologia informática. / This research addresses the pre-service mathematics teacher education, in particular their practice with computer. Considering the problems concerning teacher education courses - as, for instance, the disarticulation between the theory and the practice, and between the university education and the school reality - it was formulated the following research question: What are the perspectives, expectations and difficulties that the future teachers experience when they reflect on an educational practice using spreadsheets at the basic school? The research was developed in collaboration with two future mathematics teachers from UNESP at Rio Claro, São Paulo, Brazil. It was organized three planning meetings, ten intervention meetings in a public school, and ten reflection meeting, that always took place right after each intervention meeting. The reflection meetings were videoed and transcribed. The data were analyzed with reference to the literature. Themes were identified that could be referred to their expectation, perspectives, and difficulties. These themes included: the teaching in the classroom and the transposition of the contents; the complexity of the classroom environment; the interaction with the students; the school working conditions; being a teacher; and the use of computers.

A nossa pesquisa está dividida em duas etapas. Na primeira delas, do tipo estado do conhecimento, fizemos um mapeamento da produção brasileira relativa ao ensino de análise em dissertações e teses, artigos em periódicos e trabalhos em anais de eventos. Fizemos uma análise quantitativa desses dados e levantamos questões críticas que emergiram das discussões apresentadas tanto por esses trabalhos quanto por indagações nossas. Concluímos que a quantidade de pesquisas em ensino de análise ainda é muito pequena, há poucos docentes universitários trabalhando com essa temática e os trabalhos estão relativamente isolados entre si. Concluímos ainda que há muitas questões sem resposta sobre a importância e relevância da disciplina de análise em cursos de formação de professores da matemática. A segunda etapa de nosso trabalho traz um panorama de como vem se estruturando o programa, de um modo geral; e os objetivos, conteúdos e bibliografia da disciplina de análise em dois cursos: o da Universidade Estadual Paulista (UNESP) e o da Universidade de São Paulo (USP).

Our research is divided in two steps. The first one, the type state of knowledge, we made a mapping of the Brazilian production relative to the analysis teaching on dissertations and PhD thesis, articles in scientific journals and proceedings. A quantitative analysis of these data was made and critical issues that emerged from presented debates by theses analysis as well as our investigation were raised. It was concluded that the amount of research on analysis teaching is still very small, there are few professors who work with this topic and there is not a link between them. We still concluded that there are many unanswered questions about the importance and relevance of the subject of analysis on courses of mathematics teacher education. The second step of our research adduces an aspect about how the program is generally being built, and the goals, syllabus and bibliography of the subject of analysis in two courses in Brazilian universities: São Paulo State University (UNESP) e University of São Paulo (USP). The study was conducted through curricula and programs in the courses of analysis and calculus. Our data source, in a perspective of a qualitative research, is an analysis of documents. For their analysis, we followed the steps of reduction, presentation and conclusions. In courses at USP and UNESP, there were not specific courses of analyses or calculus in their first years, being this breakup done after the seventies. About the goals, these have never...

A Coragem da Verdade nos cursos de Licenciatura em Matemática - dos cacos arqueológicos a uma anarqueologia / The Courage of the Truth in Mathematics Degree Course - the archaeological fragments to a anarchaeology

Esta investigação de doutoramento buscou, como diria Michel Foucault, nosso principal teórico, fazer um diagnóstico do presente do Curso de Licenciatura em Matemática no Brasil, ou seja, produzir um olhar - o nosso olhar sobre este passado e sua força no presente - investigando o conceito de parresia - a coragem da verdade - dentro desse curso. Utilizamos como metodologia de investigação e escrita a arqueologia foucaultiana, pois a arqueologia nos possibilita colocar à vista as relações entre o ver e o dizer, entre o visível e o enunciável e que forças estão agindo no limiar deste processo. Permite-nos olhar a ressonância das práticas no discurso. Trata-se de uma descrição do discurso como objeto-monumento de um acontecimento. Desenvolver uma arqueologia, segundo Foucault, é produzir uma descrição histórica e filosófica sem o intuito de fazer julgamentos sobre os acontecimentos do passado com o olhar do presente. Através dos fragmentos utilizados - documentos escritos, tais como: discursos, leis, projetos políticos pedagógicos, atas e outros - descrevemos anarqueologicamente o desabrochar de ideias, a formulação de positividades, racionalidades para entender no presente como o passado se constituiu e como a construção desse passado faz vibrar atualmente forças de poder e resistência neste Curso, possibilitadas pela Coragem da Verdade. / This research aims to make difference on the history of Degree in Mathematics in our country, since we try to see and make it be seen through which practices and discourses started the first Degree in Mathematics in Brazil, created at the Faculty of Philosophy, Sciences and Languages and Literature of the University of São Paulo in 1934, and how this establishment reverberates in our Degree in Mathematics today. This doctoral research seeks, according to our main theorist, Michel Foucault, to make a diagnosis of the current Mathematics Degree Course in Brazil, that is, to create a look - our look of this past and its strength in the present - investigating the concept of parrhesia - the courage of the truth - within that course. Foucault's archeology was used as research methodology and writing, because archeology allows us to show the relationship between seeing and saying, between the visible and the expressible and what forces are acting on the threshold of this process. It allows us to look at the resonance of discourse practices. This is a description of discourse as an object-monument of an event. Developing an archeology, according to Foucault, is to produce a historical and philosophical description without the intention of making judgments about the events of the past with the look of the present. Through the fragments used - written documents such as speeches, laws, political pedagogical projects, minutes and others- we anarchaeologically describe the blossoming of ideas, formulation of positivities, rationales to understand at present how the past was constituted and how the construction of this past currently moves power strength and endurance present in this Course enabled by the Courage of the Truth.

PRESERVICE TEACHERS’ MATHEMATICAL KNOWLEDGE FOR TEACHING: FOCUS ON LESSON PLANNING, PEER TEACHING, AND REFLECTION

Bima K Sapkota (11831969) 07 July 2022 (has links)
<p>  </p> <p>Mathematics teacher educators have suggested that approximations of practice provide preservice mathematics teachers (PMTs) with opportunities to engage with, develop, and demonstrate subdomains of Mathematical Knowledge for Teaching ([MKT], Ball et al., 2008) because MKT provides a way for PMTs to understand how to contextualize their discipline-specific content knowledge for effective mathematics teaching and learning. However, the affordances and limitations of commonly used forms of approximations of practice (i.e., lesson planning and peer teaching) coupled with reflective practices to engage PMTs in subdomains of MKT are still being explored. In this study, I investigated how lesson planning, peer teaching, and associated reflections individually and collectively afforded opportunities for PMTs to demonstrate and develop the MKT subdomains. Eleven PMTs enrolled in a secondary mathematics methods course at a large Midwestern University participated in the study. My dissertation comprises three sub-studies (Sub-study “1”, “2”, and “3”), and I produced three manuscripts to individually report findings from those sub-studies. I investigated how lesson planning, peer teaching, and reflections afforded opportunities for PMTs to demonstrate and describe MKT subdomains in Sub-studies 1, 2, and 3, respectively. The findings across the sub-studies suggested that several MKT subdomains (e.g., Knowledge of Content and Teaching, Knowledge of Content and Students) were evidenced in the PMTs’ planned teacher and student actions (e.g., selecting mathematical tasks, formulating and sequencing questions), and in-the-moment actions and decisions (e.g., mathematically representing students’ responses, implementing mathematical tasks). Several aspects of MKT subdomains (e.g., evaluate the diagnostic potential of tasks) were strongly evidenced only in the PMTs’ lesson plans whereas other aspects (e.g., modifying tasks based on students’ responses) were evidenced only in peer teaching. These findings suggested that various forms of approximations of practice (planned and enacted actions) created unique opportunities for the PMTs to engage with and demonstrate MKT. I also found that the PMTs reflected on some subdomains of MKT that were not evidenced in their approximated practices, indicating that how PMTs describe the MKT subdomains is not entirely a result of what subdomains they engage in during approximations of practice. My findings also revealed limitations of using approximations of practice to engage PMTs with MKT subdomains. The MKT subdomains that required the PMTs to think about students’ alternative mathematical concepts, big mathematical ideas, and non-standard mathematics problem-solving strategies were least evidenced across the approximations of practice and reflections. These findings have two primary implications for mathematics teacher educators. First, I invite mathematics teacher educators to engage PMTs in multiple forms of approximations of practice to optimize their opportunities to engage with, demonstrate, and develop the MKT subdomains. Second, I suggest potential instructional activities (e.g., inviting PMTs to reflect on their roles as students and teachers during peer teaching) that could be incorporated into approximations of practice to address the existing limitations. Broadly, I invite mathematics teacher educators to design instructional activities at the intersection of mathematics content and pedagogy, collaborating with colleagues to enhance these opportunities across programs.</p> <p>  </p>

Trata-se de uma pesquisa de cunho qualitativo. Mais especificamente, utilizei a abordagem metodológica da Teoria Fundamentada nos Dados (TFD). Nessa abordagem, o pesquisador deve construir uma teoria a partir do desenvolvimento de conceitos, categorias, propriedades e dimensões. A TFD foi utilizada na construção e na análise dos dados, estes, produzidos a partir de quatro fontes: observação no Ambiente Virtual de Aprendizagem (AVA), entrevistas com professores, tutores e alunos dos cursos, análise dos documentos oficiais destes cursos e um diário de campo do pesquisador. Os dados produzidos permitiram um diálogo com as ideias de polidocência, que discute a fragmentação do ensino em cursos a distância, e do construto seres-humanos-com-mídias, que propõe que humanos e tecnologias atuam juntos na produção do conhecimento matemático. Esses dados permitiram inferir que há dois papéis em evidência, cada um analisado em uma das categorias que emergiram, intituladas “TD e seu papel na estruturação da disciplina” e “TD e seu papel na docência da disciplina”. Em cada uma das categorias foram desenvolvidas três propriedades. Na primeira: o design da disciplina, a avaliação online e a interação. Na segunda categoria, as propriedades exploradas foram: a mudança de papéis, a estratégia e as dificuldades epistemológicas. Posteriormente, essas categorias foram integradas em uma categoria central que indica a teoria que defende a existência de um construto polidocentes-com-mídias para os dados produzidos e analisados. Esse construto sugere que as TD atuam no coletivo de trabalhadores da polidocência, alterando papéis e desvelando outros neste coletivo. Para isso, é necessário que o AVA seja um ambiente rico em interações colaborativas, nas quais o diálogo seja constantemente incentivado por professores e tutores. Com o construto polidocentes-com-mídias elaborado, o modelo foi, então, verificado nas disciplinas analisadas, o que corroborou a necessidade das interações colaborativas. Com esta pesquisa, espera-se que outras sejam iniciadas no sentido de investigar que outros papéis as TD podem desempenhar, não apenas no ensino, como também na aprendizagem de outras disciplinas em contextos semelhantes. / This research aims to understand the role of Digital Technologies (DT) in the teaching of Calculus in distance education, in particular, in the Pre-Service Mathematics Teacher Education of the Open University of Brazil (UAB). A qualitative research approach was used, specifically the methodological approach of Grounded Theory (GT). In this approach, the researcher builds a theory grounded in concepts, categories, properties and dimensions identified through analysis of the data. The data were produced from four sources: observation in Virtual Learning Environment (VLE), interviews with teachers, tutors and students of the courses, analysis of official documents of these courses, and research field notes. Based on the produced data, it was possible to build a dialogue between poly-teaching ideas regarding the fragmentation of teaching in distance learning courses, and the theoretical construct humans-with-media, which proposes that humans and technology work together in the production of mathematical knowledge. Two roles of DT emerged as analytic categories: "DT and its role in the structuring of the course" and "DT and its role in teaching the course". In each category, three properties were developed. In the first category, they were: the course design, evaluation and online interaction. In the second category, the properties explored were: changing roles, strategy and epistemological difficulties. Later, these categories were integrated into a central category that formed the basis for defending the existence of the theoretical construct “poly-teachers-with-media”. This construct suggests that DT act in the collective of poly-teaching workers, changing roles and revealing others in this collective. Therefore, it is necessary for the VLE to be an environment rich in collaborative interactions, in which the dialogue is constantly encouraged by teachers and tutors. Once the notion of the construct poly-teachers-with-media was developed, the model was then verified in the analyzed courses, which supported the relationship with the need for collaborative interactions. With this research, it is hoped that others will begin to investigate the other roles that DT can play, not only in teaching, but also in the learning of different subjects in similar contexts.

Knowing the World Through Mathematics: Explorations of a Social Justice Mathematics Course

Michael R Lolkus (13047873) 14 July 2022 (has links)
<p> </p> <p>Issues of social justice continue to permeate all aspects of life in the United States. Acknowledging recent calls for racial justice, as well as efforts to restrict what is taught in mathematics classrooms, researchers and practitioners are increasingly exploring the promises of teaching mathematics for social justice in secondary mathematics classrooms. This dissertation contributes to research about how a social justice mathematics course can be utilized in teacher education programs to support prospective mathematics teachers’ (PMTs’) development of their mathematics identities, as well as how PMTs translate social justice mathematics theory into</p> <p>practice with their secondary mathematics students. This research complexifies the role of primarily white mathematics teachers and teacher educators working toward teaching</p> <p>mathematics for social justice by foregrounding some of the ways in which social justice mathematics curricula and instruction may continue to center whiteness. </p> <p><br></p> <p>This dissertation includes three studies focused on the design and delivery of a social justice mathematics course offered to undergraduate students, as well as the learning outcomes</p> <p>for 11 PMTs enrolled in the first iteration. As such, each study is formatted for submission to a research journal and contains its own questions, methods, findings, discussion, and conclusion. </p> <p><br></p> <p>The first and second studies detail the experiences of PMTs in a social justice mathematics course. In the first study, I explored how engaging in such a course contributed to PMTs’ mathematics identities. Findings in this case study suggest that sustained engagement with social justice mathematics can contribute to PMTs’ conceptions of mathematics and encourage them to address issues of social justice in their mathematics classrooms. Building on this, three of the PMTs enrolled in the course and I engaged in a critical participatory action research study to investigate their experiences working toward teaching mathematics for social justice in their secondary mathematics field placements. Prior to engaging their students with social justice mathematics tasks, the PMTs focused on developing relationships and trust with students and also maintained a commitment to engaging students with dominant mathematics. </p> <p><br></p> <p>Informed by a finding in the first study (i.e., PMTs continued to view mathematics as objective and neutral), in the third study, I investigated the prominence of whiteness in the development and facilitation of the course. Using action research and critical whiteness studies, I detail areas in which I perpetuated whiteness, as well as areas in which I began to make progress.</p>
