abstract: Efforts to privilege STEM (Science, Technology, Engineering, and Mathematics) disciplines, initiatives, and industries in American discourse are arguably the foremost expressions of scientific authority in contemporary educational policy. Citing a diverse body of STEM literature, I discuss the histories and rationales that sustain the promotion of STEM. In doing so, I appropriate two concepts -Michel Foucault's Regime of Truth and Hayden White's Emplotment- for the purpose of analyzing the complex interests embodied by STEM discourse. I argue that the Sputnik Narrative is the prevailing story in STEM advocacy discourse. I claim that STEM advocates typically emplot this history as a Romance. Furthermore, I classify two major bases of appeal (rationales) that appear within this literature to justify STEM projects and proposals, "competition" and "equity." Throughout my writing, I cite discursive strategies for challenging and reimagining STEM history. My goal in indicating these sites of narrative possibilities is broaden the discursive field to new, perhaps liberating possibilities. / Dissertation/Thesis / M.A. Social and Philosophical Foundations of Education 2014

Computer Algebra Systems (CAS) have been changing the mathematics instruction requirements for many years. Since the tendency of using CAS in mathematics instruction has been rising for decades and reports have often been positive, the implementation of notebook classes seems to be the consequent next step of mathematics instruction supported by computers. Experiences that have been made with the use of CAS in PC-rooms can be transformed directly into the classroom. Hence the use of CAS is no longer limited to certain rooms. The permanent availability of the notebook with installed CAS offers the chance to realize these concepts that have already been approved with the use of CAS so far. The following speech shall show what these concepts could look like and that the use of notebooks is not only the further development of teaching in PC-classes. Examples from personal experience in teaching will especially show meanders and thought-provoking impulses in order to support teachers finding their way into teaching mathematics instruction in notebook classes successfully. Please allow me to point out two things in the beginning: (1) Yes, I am a vehement supporter of the use of notebooks (and the use of CAS in particular) in mathematics instruction. (2) No, I do not believe that teachers who have chosen another path (or at least partly) are teaching badly.

The question that guided the development of the research was: What are characteristics emerge from the formative process in a collaborative group of mathematics teachers to use computers in their teaching? This research is qualitative, of type participant observation. The data collection was carried out face of meetings a collaborative group of math study entitled Collaborative Study in Mathematics Education Group (CSMEG). Discussions of audio recorded meetings were used; oral and written narratives on the teaching practice; activity of scripts built out from the work proposal with the use of information technology and e-mails from the group on the profile and individual graduation and the sharing activities. For the analysis, we used the theoretical reference on teacher education, especially on reflective practice, collaborative groups and information technology in mathematics teaching. The reading of the data allowed to establish a guiding axis that highlights aspects of content and reflexive dynamics found both in the preparation of mathematical activities and in developing classroom environments with computer technology. From the discussion of the shaft were constructed three categories of analysis: 1. The computer technology insertion on collaborative group; 2. The computer technology insertion on mathematics education; and 3 Reflective practices on collaborative group. The results indicate that the pedagogical practice needs to be the starting point of reflective learning process, as shown in the proposed content and collective choices of the group during construction activities. The computer technology insertion's potentiality of visualizing and development of activities help on exploiting and relations of mathematical concepts. The elaboration of activities with the use of computer technology directed to individual interests contribute to the redefinition of the mathematical concepts and knowledge of the practice. Moreover, the reflective discussions that permeated the elaborations of the activities with the use of computer helped the teachers analyze and build meaningful activities with a look at content, to the student and to their knowledge. / O objetivo dessa pesquisa é compreender o processo formativo desenvolvido em um grupo de professores de matemática pautados na inserção do uso da informática em suas práticas pedagógicas. A questão que norteou o desenvolvimento da pesquisa foi: Quais as características que emergem do processo formativo em um grupo colaborativo de professores de matemática para utilizarem o computador na sua prática pedagógica? Esta pesquisa é qualitativa, do tipo observação participante. A coleta de dados se deu a partir dos encontros presenciais de um grupo colaborativo de estudo de matemática intitulado Grupo Colaborativo de Estudos em Educação Matemática (GCEEM). Foram utilizadas as discussões audiogravadas dos encontros; narrativas orais e escritas sobre a prática docente; roteiros de atividade construídos a partir da proposta de trabalho com o uso da informática e e-mails do grupo sobre o perfil e formação individual dos participantes e o compartilhamento das atividades. Para a análise foram utilizados o referencial teórico sobre formação de professores, em especial sobre prática reflexiva, grupos colaborativos e a tecnologia da informática no ensino de matemática. A leitura dos dados permitiu estabelecer um eixo norteador que destaca os aspectos de conteúdo e dinâmicas reflexivas encontradas tanto na elaboração das atividades matemáticas quanto no desenvolvimento em ambientes de sala de aula com a tecnologia de informática. A partir da discussão do eixo construímos três categorias de análise: 1. A inserção da informática no grupo colaborativo; 2. A inserção da informática no ensino de matemática e 3. Práticas reflexivas no grupo colaborativo. Os resultados indicam que a prática pedagógica necessita ser o ponto inicial do processo formativo reflexivo, como apresentado nas propostas de conteúdos e opções coletivas do grupo durante a construção das atividades. A potencialidade da inserção da informática para a visualização e desenvolvimento de atividades auxiliam nas explorações e relações dos conceitos matemáticos. A elaboração de atividades com o uso da informática direcionadas aos interesses individuais contribuem para a ressignificação dos conceitos matemáticos e para os conhecimentos da prática. As discussões reflexivas que permearam as elaborações das atividades com o uso da informática contribuíram para que os professores analisassem e construíssem atividades significativas com um olhar para o conteúdo, para o aluno e para seus saberes

What knowledge do teachers need for integrating appropriate digital technologies in teaching mathematics? An overarching construct called TPACK is proposed as the interconnection and intersection of knowledge among technology, pedagogy, and content and is referred to as the total knowledge package for teaching mathematics with technology. Five stages in the process of developing TPACK - recognizing, accepting, adapting, exploring, and adapting – describe the process of teachers’ learning to integrate technology. Teachers learn to teach mathematics from their own learning – K-12 mathematics - collegiate mathematics coursework, teacher preparation program, field experiences and professional development as they teach mathematics. The challenge is to identify appropriate experiences to guide this integration of technology in teaching mathematics in ways that develop TPACK. A framework for these experiences directs attention to emergent social and psychological perspectives.

It s inserted in the Project AProvaME (Argumentation and Proof in School Mathematics) that proposes the investigation of conceptions of argumentation and proof in the teaching of mathematics in schools in the state of São Paulo and to form a group of researchers to elaborate situations of learning involving arguments and proof to be investigated in the classroom. The analysis of the collection, in our research, is based on the work done by BALACHEFF et. al. (2001) which presents possible activities that may involve argumentation and proof classifying them into various types and levels. We have used this classification, when it refers to the Fundamental Theorem of Arithmetic and the Theorem of Pythagoras, to consider the theoretical text and the respective exercises presented in the collection that are related to argumentation and proof. We have noticed that the proposed activities may basically be classified as "tasks of initiation to proof." We conclude, in our analysis, that the collection is not designed to work with argumentation and proof to develop such skills in students when presenting the Fundamental Theorem of Arithmetic and the Theorem of Pythagoras, and also when proposing its activities. We propose, at the end of our work, dynamic activities that may complement those that are present in the collection, aiming to help in the development of new approaches on argumentation and proof in the classroom / Este trabalho tem o objetivo de analisar como a coleção Matemática e Realidade aborda argumentação e prova quando trata do Teorema Fundamental da Aritmética e do Teorema de Pitágoras. Ele está inserido no projeto AProvaME - (Argumentação e Prova na Matemática Escolar) que propõe a investigação de concepções de argumentação e prova no ensino de matemática em escolas do estado de São Paulo e formar grupo de pesquisadores para elaborar situações de aprendizagem envolvendo argumentação e prova para serem investigadas em sala de aula. A análise da coleção, em nossa pesquisa, tem como fundamento o trabalho desenvolvido por BALACHEFF et. al. (2001) que apresenta possíveis atividades que possam envolver argumentação e prova classificando-as em vários tipos e níveis. Utilizamos esta classificação para analisar, quando trata do Teorema Fundamental da Aritmética e do Teorema de Pitágoras, o texto teórico e os respectivos exercícios apresentados na coleção e que estejam relacionados com argumentação e prova. Constatamos que são propostas basicamente atividades que podem ser classificadas como de tarefas de iniciação a prova . Concluímos, em nossa análise, que a coleção não visa o trabalho com argumentação e prova para desenvolver tais competências nos alunos quando apresenta os temas Teorema Fundamental da Aritmética e Teorema de Pitágoras e também quando propõe as respectivas atividades. Propomos ao final de nosso trabalho, atividades dinâmicas que podem complementar as que estão presentes na coleção, com o propósito de contribuir na elaboração de novas abordagens sobre argumentação e prova em sala de aula
