A Quadruple-Based Text Analysis System for History and Philosophy of Science

January 2014 (has links)
abstract: Computational tools in the digital humanities often either work on the macro-scale, enabling researchers to analyze huge amounts of data, or on the micro-scale, supporting scholars in the interpretation and analysis of individual documents. The proposed research system that was developed in the context of this dissertation ("Quadriga System") works to bridge these two extremes by offering tools to support close reading and interpretation of texts, while at the same time providing a means for collaboration and data collection that could lead to analyses based on big datasets. In the field of history of science, researchers usually use unstructured data such as texts or images. To computationally analyze such data, it first has to be transformed into a machine-understandable format. The Quadriga System is based on the idea to represent texts as graphs of contextualized triples (or quadruples). Those graphs (or networks) can then be mathematically analyzed and visualized. This dissertation describes two projects that use the Quadriga System for the analysis and exploration of texts and the creation of social networks. Furthermore, a model for digital humanities education is proposed that brings together students from the humanities and computer science in order to develop user-oriented, innovative tools, methods, and infrastructures. / Dissertation/Thesis / Doctoral Dissertation Biology 2014

Three Perspectives on Multilevel Selection: An Experimental, Historical, and Synthetic Analysis of Group-Level Selection

January 2014 (has links)
abstract: During the 1960s, the long-standing idea that traits or behaviors could be explained by natural selection acting on traits that persisted "for the good of the group" prompted a series of debates about group-level selection and the effectiveness with which natural selection could act at or across multiple levels of biological organization. For some this topic remains contentious, while others consider the debate settled, even while disagreeing about when and how resolution occurred, raising the question: "Why have these debates continued?" Here I explore the biology, history, and philosophy of the possibility of natural selection operating at levels of biological organization other than the organism by focusing on debates about group-level selection that have occurred since the 1960s. In particular, I use experimental, historical, and synthetic methods to review how the debates have changed, and whether different uses of the same words and concepts can lead to different interpretations of the same experimental data. I begin with the results of a group-selection experiment I conducted using the parasitoid wasp Nasonia, and discuss how the interpretation depends on how one conceives of and defines a "group." Then I review the history of the group selection controversy and argue that this history is best interpreted as multiple, interrelated debates rather than a single continuous debate. Furthermore, I show how the aspects of these debates that have changed the most are related to theoretical content and empirical data, while disputes related to methods remain largely unchanged. Synthesizing this material, I distinguish four different "approaches" to the study of multilevel selection based on the questions and methods used by researchers, and I use the results of the Nasonia experiment to discuss how each approach can lead to different interpretations of the same experimental data. I argue that this realization can help to explain why debates about group and multilevel selection have persisted for nearly sixty years. Finally, the conclusions of this dissertation apply beyond evolutionary biology by providing an illustration of how key concepts can change over time, and how failing to appreciate this fact can lead to ongoing controversy within a scientific field. / Dissertation/Thesis / Doctoral Dissertation Biology 2014

Contemplating the Use of Neuroimaging as Evidence in Criminal Sentencing

January 2014 (has links)
abstract: Neuroimaging has appeared in the courtroom as a type of `evidence' to support claims about whether or not criminals should be held accountable for their crimes. Yet the ability to abstract notions of culpability and criminal behavior with confidence from these imagines is unclear. As there remains much to be discovered in the relationship between personal responsibility, criminal behavior, and neurological abnormalities, questions have been raised toward neuroimaging as an appropriate means to validate these claims. This project explores the limits and legitimacy of neuroimaging as a means of understanding behavior and culpability in determining appropriate criminal sentencing. It highlights key philosophical issues surrounding the ability to use neuroimaging to support this process, and proposes a method of ensuring their proper use. By engaging case studies and a thought experiment, this project illustrates the circumstances in which neuroimaging may assist in identifying particular characteristics relevant for criminal sentencing. I argue that it is not a question of whether or not neuroimaging itself holds validity in determining a criminals guilt or motives, but rather a proper application of the issue is to focus on the way in which information regarding these images is communicated from the `expert' scientists to the `non-expert' making decisions about the sentence that are most important. Those who are considering this information's relevance, a judge or jury, are typically not well versed in criminal neuroscience and interpreting the significance of different images. I advocate the way in which this information is communicated from the scientist-informer to the decision-maker parallels in importance to its actual meaning. As a solution, I engage Roger Pielke's model of honest brokering as a solution to ensure the appropriate use of neuroimaging in determining criminal responsibility and sentencing. A thought experiment follows to highlight the limits of science, engage philosophical repercussions, and illustrate honest brokering as a means of resolution. To achieve this, a hypothetical dialogue reminiscent of Kenneth Schaffner's `tools for talking' with behavioral geneticists and courtroom professionals will exemplify these ideas. / Dissertation/Thesis / Masters Thesis Biology 2014

The Soft Megamachine: Lewis Mumford's Metaphor of Technological Society and Implications for (participatory) Technology Assessment

January 2014 (has links)
abstract: This dissertation explores the megamachine, a prominent metaphor in American humanist and philosopher of technology, Lewis Mumford's Myth of the Machine series. The term refers critically to dynamic, regimented human capacities that drive scientific and technical innovation in society. Mumford's view of the nature of collectives focuses on qualities and patterns that emerge from the behavior of groups, societies, systems, and ecologies. It is my aim to reenergize key concepts about collective capacities drawn from Lewis Mumford's critique of historical and modern sociotechnical arrangements. I investigate the possibility of accessing those capacities through improved design for Technology Assessment (TA), formal practices that engage experts and lay citizens in the evaluation of complex scientific and technical issues. I analyze the components of Mumford's megamachine and align key concerns in two pivotal works that characterize the impact of collective capacities on society: Bruno Latour's Pasteurization of France (1988) and Elias Canetti's Crowds and Power (1962). As I create a model of collective capacities in the sociotechnical according to the parameters of Mumford's megamachine, I rehabilitate two established ideas about the behavior of crowds and about the undue influence of technological systems on human behavior. I depart from Mumford's tactics and those of Canetti and Latour and propose a novel focus for STS on "sociotechnical crowds" as a meaningful unit of social measure. I make clear that Mumford's critique of the sociotechnical status quo still informs the conditions for innovation today. Using mixed mode qualitative methods in two types of empirical field studies, I then investigate how a focus on the characteristics and components of collective human capacities in sociotechnical systems can affect the design and performance of TA. I propose a new model of TA, Emergent Technology Assessment (ETA), which includes greater public participation and recognizes the interrelationship among experience, affect and the material in mediating the innovation process. The resulting model -- the "soft" megamachine --introduces new strategies to build capacity for responsible innovation in society. / Dissertation/Thesis / Doctoral Dissertation Human and Social Dimensions of Science and Technology 2014

Advancing the Causal Theory of Natural Selection

January 2016 (has links)
abstract: The Modern Synthesis embodies a theory of natural selection where selection is to be fundamentally understood in terms of measures of fitness and the covariance of reproductive success and trait or character variables. Whether made explicit or left implicit, the notion that selection requires that some trait variable cause reproductive success has been deemphasized in our modern understanding of exactly what selection amounts to. The dissertation seeks to advance a theory of natural selection that is fundamentally causal. By focusing on the causal nature of natural selection (rather than on fitness or statistical formulae), certain conceptual and methodological problems are seen in a new, clarifying light and avenues toward new, interesting solutions to those problems are illustrated. First, the dissertation offers an update to explicitly causal theories of when exactly a trait counts as an adaptation upon fixation in a population and draws out theoretical and practical implications for evolutionary biology. Second, I examine a case of a novel character that evolves by niche construction and argue that it evolves by selection for it and consider implications for understanding adaptations and drift. The third contribution of the dissertation is an argument for the importance of defining group selection causally and an argument against model pluralism in the levels of selection debate. Fourth, the dissertation makes a methodological contribution. I offer the first steps toward an explicitly causal methodology for inferring the causes of selection—something often required in addition to inferring the causes of reproductive success. The concluding chapter summarizes the work and discusses potential paths for future work. / Dissertation/Thesis / Doctoral Dissertation Biology 2016

Development, Evolution, and Teeth: How We Came to Explain The Morphological Evolution of the Mammalian Dentition

January 2017 (has links)
abstract: This dissertation begins to lay out a small slice of the history of morphological research, and how it has changed, from the late 19th through the close of the 20th century. Investigators using different methods, addressing different questions, holding different assumptions, and coming from different research fields have pursued morphological research programs, i.e. research programs that explore the process of changing form. Subsequently, the way in which investigators have pursued and understood morphology has witnessed significant changes from the 19th century to modern day research. In order to trace this shifting history of morphology, I have selected a particular organ, teeth, and traced a tendril of research on the dentition beginning in the late 19th century and ending at the year 2000. But even focusing on teeth would be impossible; the scope of research on this organ is far too vast. Instead, I narrow this dissertation to investigation of research on a particular problem: explaining mammalian tooth morphology. How researchers have investigated mammalian tooth morphology and what counts as an explanation changed dramatically during this period. / Dissertation/Thesis / Doctoral Dissertation Biology 2017

Les nanotechnologies ou l'impensé de l'épistémologie : d'une science qui représente à une science qui intervient / Nanotechnology or the unthought of epistemology : from a representing science to an intervening one

Guèye, Thierno 18 June 2014 (has links)
Nous examinons une question que l'avènement des nanotechnologies rend de plus en plus pressante pour la philosophie des sciences. Elle prend les allures d'une critique de cette dernière en se fondant sur quelques théories philosophiques, représentatives et suffisamment originales sur la science, développées par Thomas Kuhn, Imre Lakatos, Ian Hacking et Serge Robert. Les différents discours sur les nanos et plus précisément le concept de nanotechnologie se sont révélés, à tout le moins, polysémiques et décrivent parfois prématurément une activité qui n'existe pas encore. Ainsi, nous avons requalifié le concept de nanotechnologie en « nanotechnoscience ». Puis nous avons confronté les philosophies des sciences que nous avons retenues aux fins de les mettre à l'épreuve de ce qui apparaît comme un impensé de leurs philosophies, notamment la dimension technologique de la science souvent connue et reconnue, mais « sous-traitée » et reléguée au mieux au second plan. Nos recherches ont donc porté sur chacune des philosophies que nous avons annoncées, sur les nanotechnosciences elles-mêmes, la philosophie de la technologie, mais aussi sur celle naissante des technosciences et des nanotechnosciences sans oublier notre ouverture à des fins heuristiques sur la philosophie du langage d'Austin et la praxéologie de Denis Vernant. Dans cette étude, nous avons traité d'étymologie, d'histoire du préfixe nano et de définition. Puis, nous avons examiné attentivement les différentes philosophies des sciences par lesquelles il nous a paru pertinent d'examiner les nanotechnosciences émergentes afin de voir ce qui dans ces doctrines permettrait d'envisager une réflexion philosophique sur les nanos. Sachant que ces pensées privilégient la représentation sur l'intervention, nous nous sommes posés la question de la place de la technologie dans ces systèmes philosophiques avec l'idée que la technologie est une condition nécessaire quoique non suffisante de toute philosophie à prétention technoscientifique ou nanotechnoscientifique. C'est dans cette optique que nous avons sollicité la théorie des paradigmes, puis celle du falsificationnisme sophistiqué revu et corrigé par le correctionnisme de Robert avant de tenter l'interventionnisme de Hacking. Nous avons pu constater l'omniprésence de la technologie tout comme l'hétérogénéité de la place qui lui est accordée dans ces théories philosophiques. Ainsi de Kuhn à Hacking, la reconnaissance du rôle et de la place de la technologie va crescendo, au point de nous inviter à penser les nanotechnosciences en termes d'« actes de discours ». L'enchevêtrement ou l'entrelacement entre science et technologie nous a inspiré deux analogies : la première avec l'idée de « contexte de performance oral » de Mamoussé Diagne analogue elle-même à la seconde, la performativité introduite et initiée par les réflexions d'Austin sur le discours ordinaire. Notre investigation prend les allures d'une mise à l'épreuve de toutes ces philosophies à l'aune de la place qu'occupe la technologie dans leurs systèmes respectifs. Nous avons eu recours à l'analyse comparative des discours philosophiques sur la science ainsi que ce que nous avons appris sur les pratiques scientifiques, le tout complété par une approche lexicométrique basée sur le corpus des principaux ouvrages de Kuhn, Lakatos, Robert et Hacking. Notre démarche nous a amené à mettre en cause l'étymologie du préfixe nano trop hâtivement attribuée au grec alors qu'il serait plus à propos de la considérer comme latine, puis nous avons tenté d'établir l'idée que les « nanotechnologies » n'existent pas et que ce que l'on appelle bien souvent ainsi relève d'un abus de langage et d'une sorte d'anachronisme inversée. De cette critique nous avons tenté de tirer des leçons qui ont inspiré la requalification conceptuelle de l'activité qu'est censé désigner ce morphème en « nanotechnoscience » que nous avons redéfini en tenant compte de plusieurs facteurs déterminants. / This thesis focuses on the consideration of a question that the advent of what is called nanotechnology makes it increasingly urgent to philosophy in general and the philosophy of science in particular because of the inexistence of the “nanotechnology” stricto sensu, the lack of good definition and the default of something like a “nanophilosophy”. We critique the latter based on some philosophical, representative and sufficiently original theories of science, developed by Thomas Kuhn, Imre Lakatos, Ian Hacking and Serge Robert. Different discourses on nanos and more specifically the concept of nanotechnology proved, at least, polysemous and sometimes describe an activity which in the strict sense does not exist prematurely. Thus, we have reclassified the concept of nanotechnology "nanotechnoscience" and proposed a more rigorous definition emphasizing the hybrid nature of this activity, both theoretical and practical, scientific and technological. Then we compared the philosophies of science that we have selected to make them confront what appears to be an unthought of their philosophies, including the technological dimension of science often known and recognized, but "outsourced" and relegated to better secondary. Our research has therefore focused on each of the philosophies that we announced on the nanotechnosciences themselves, philosophy of technology, but also on emerging technosciences and nanotechnoscience not forgetting our opening for heuristic purposes on the philosophy of language of Austin and praxeology of Denis Vernant. Then, we carefully examined the different philosophies of science which seemed appropriate to consider the emerging nanotechnosciences so as to see what in these doctrines would help envisaging a philosophical reflection on the Nano. Knowing that these thoughts favor representing rather than intervening, we questioned the role of technology in these philosophical systems with the idea that technology is a necessary though not sufficient condition for any claim of technoscientific or nanotechnoscientific philosophy. It is in this context that we solicited the paradigms theory, then the sophisticated falsificationism reviewed and corrected by Robert's correctionism before attempting interventionism Hacking's interventionism. During this exercise we have seen the pervasiveness of technology as well as the heterogeneity of the place it is granted in these philosophical theories. The entanglement or intertwining between science and technology inspired us two analogies: the first with the idea of "context of oral performance" by Mamoussé Diagne, analogous itself to the second, performativity introduced and initiated by Austin's reflections on ordinary language. Our investigation takes on the appearance of a testing of all these philosophies in terms of the place of technology in their respective systems. To achieve this, we resorted to the comparative analysis of philosophical discourse on science and what we have learned about scientific practices, complemented by a lexicometric approach based on the corpus of the principal works published from Kuhn, Lakatos, Robert and Hacking. From our critique we have tried to draw lessons that inspired the conceptual requalification of the activity that this morpheme is intended to mean into "nanotechnoscience" which we have redefined. This established at the end of this analysis, we could say that neither the philosophy of Kuhn or Lakatos, nor that of Robert leave enough space for technology to position itself as philosophies of technosciences. The one which seems the most appropriate is the interventionism defended by Hacking, but which Gilbert Hottois criticized for not having taken the step that would have led to a philosophy of authentic technosciences. It was then that tracks to Bacon and Peirce are suggested respectively by Hacking and Schmidt and Nordmann.

Discutindo a natureza da ciência a partir de episódios da história da cosmologia / Discussing the nature of science from episodes of the history of cosmology

Alexandre Bagdonas Henrique 30 May 2011 (has links)
Nesta pesquisa estudamos alguns episódios da história da cosmologia no século XX, buscando episódios interessantes que permitiram a discussão de certos aspectos da natureza da ciência de forma explícita na formação inicial de professores de ciências. Um dos objetivos desta pesquisa é fornecer subsídios para que se possa ensinar cosmologia com uma abordagem histórico-filosófica, o que é sugerido pelos PCN no tema estruturador \"Universo, Terra e Vida\". Esta proposta busca contribuir para a introdução de conteúdos de história e filosofia da ciência nos cursos de formação de professores e consequentemente na educação básica. O episódio histórico escolhido foi a controvérsia entre a teoria do Big Bang e a do Estado Estacionário, que ocorreu a partir da segunda metade do século XX. Tendo em vista a possibilidade de analisar as influências religiosas sobre essa controvérsia, argumentamos sobre a importância de se discutir a relação entre ciência e religião nas aulas de física, utilizando episódios da história da cosmologia como tema motivador. São apresentados três personagens históricos envolvidos nas controvérsias cosmológicas da década de 1950: o Papa Pio XII, Fred Hoyle e Georges Lemaître, que escreveram textos sobre relações entre cosmologia e religião. Após este estudo teórico, foi realizada a aplicação e avaliação de uma sequência didática durante a disciplina História da Ciência, do curso de Licenciatura em Ciências Exatas da Universidade de São Paulo, campus São Carlos. Nessa aplicação, investigamos a viabilidade do uso dos episódios históricos estudados como forma de discutir questões sobre a natureza da ciência, como a existência de um método científico e questão das \"provas\" na cosmologia. Além disso, foram realizados debates sobre estratégias para lidar com eventuais conflitos entre ciência e religião durante aulas de cosmologia, tendo como base a leitura de textos escritos por personagens da história da cosmologia. Os dados de pesquisa foram coletados utilizando instrumentos típicos de pesquisa qualitativa, como resposta a questionários, análise das atividades realizadas durante as aulas, e de textos produzidos pelos alunos. A partir da análise destes dados, consideramos que as atividades propostas mostram-se uma boa forma de discutir sobre a natureza da ciência, já que os alunos puderam não só aprender conteúdos de cosmologia, mas também refletir sobre diferenças e semelhanças entre a ciência e outras formas de ver o mundo. / In this research we studied some episodes in the history of cosmology in the twentieth century, seeking interesting episodes that allowed the discussion of certain aspects of nature of science explicitly in preservice teacher training. One objective of this research is to provide subsidies for teaching cosmology with a historical-philosophical approach, which is suggested by the PCN (National curricular parameters) in the theme \"Universe, Earth and Life.\" This proposal seeks to contribute to the introduction of contents of history and philosophy of science in teacher training courses and consequently in basic education. The episode chosen was the historical controversy between Big Bang and Steady State theory, which occurred during the second half of the twentieth century. Given the opportunity to consider religious influences on this controversy, we argue about the importance of discussing the relationship between science and religion in physics classes, using episodes in the history of cosmology as a motivating theme. We present three historical characters involved in the controversies of the cosmological decade 1950: Pope Pius XII, Fred Hoyle and Georges Lemaître, who wrote texts on relations between cosmology and religion. After this theoretical study was performed an implementation and evaluation of a didactic sequence during the course History of Science, the course \"Higher education in Sciences\", in the University of São Paulo, São Carlos campus. In this application, we investigate the feasibility of using the historical episodes studied as a way to discuss issues about the nature of science, as the existence of a scientific method and the question of the \"proof\" in cosmology. In addition, discussions have been undertaken on strategies for dealing with conflicts between science and religion classes for cosmology, based on the reading of texts written by characters in the history of cosmology. Survey data were collected using typical tools of qualitative research, in response to questionnaires, review of activities during lessons, and texts produced by students. From the analysis of these data, we consider that the proposed activities prove to be a good way to discuss the nature of science, since students could not only learn content of cosmology, but also reflect on differences and similarities between science and other ways of seeing the world.

A perpetuação deste modelo deve-se, principalmente, ao processo de formação dos atuais professores, e a forma como o conteúdo presente no material didático utilizado por estes é apresentado. Visto que os conceitos são construídos de forma lenta, gradual, com avanços e recuos, pois expressam as tentativas de argumentação elaboradas ao longo da história; os fatores no Ensino de Ciências e Biologia acima citados tornam-se obstáculos para a inserção da História da Ciência no Ensino de Ciências e Biologia. O processo de construção dos conceitos sobre circulação sanguínea não expressa tentativa de entendimento do movimento do sangue no corpo humano. Além disso, o levantamento e pesquisa bibliográfica que realizamos caracteriza de forma exemplar, a construção de uma explicação científica e a influência do contexto social e religioso na produção de um conhecimento científico e, também, a resistência às mudanças por parte principalmente de indivíduos respeitados da época, evidenciam os percalços pelos quais a ciência passa. Enfrentamos diversas dificuldades ao realizar esse levantamento e pesquisa bibliográfica. Entre algumas, podemos citar a dificuldade de acesso às fontes primárias, barreiras lingüísticas e problemas na interpretação dos determinantes históricos. Essas barreiras são também enfrentadas por autores de livros didáticos e professores que desejam inserir a História da Ciência, respectivamente, no material didático e na prática docente. Assim, esse trabalho tem por objetivo produzir um texto didático para o ensino, apontando o dinamismo e a não neutralidade da ciência e, com isso... / Frequently, Science and Biology teaching does not present the determinants and contexts involved in the building of a concept, showing it so dogmatic and rote. The perpetuation of such a model is due, mainly, to the process of training of current teachers, and how the content in the teaching material used by them is presented. Since the concepts are built on a slow, gradual, with advances and setbacks, because attempts to express the arguments made throughout history, factors in the Teaching of Science and Biology mentioned above become obstacles to the insertion of the History of Science in the Teaching of Science and Biology. The process of concepts construction expressed on blood circulation does not attempt to understanding the movement of blood in the human body. Moreover, the lifting and literature search conducted in this study features in an exemplary fashion, the construction of a scientific explanation and the influence of social and religious context in the production of scientific knowledge and also the resistance to change, mainly from respected individuals of the time , highlighting the mishaps faced by science. Various difficulties were faced to achieve this survey and literature search. Among some, we can cite the difficulty of access to primary sources, language barriers and problems in the interpretation of historical determinants. These barriers are also faced by authors of textbooks and teachers who wish to enter the History of Science, respectively, in the educational materials and teaching practice. Thus, this work aims to produce a teaching text for teaching, indicating the dynamism and non-neutrality of science and thereby, helping to minimize some of the difficulties found in integrating the History of Science in Science and Biology teaching.

Dessa forma, tais reflexões poderiam possibilitar a humanização da Ciência, o desenvolvimento do pensamento crítico, além de melhorar a compreensão dos conteúdos e a formação do professor. Isto nos remete aos cursos de Licenciatura e às possibilidades formativas que estes vêm proporcionando em relação a esta temática. Assim, esta pesquisa buscou compreender qual o perfil formativo dos quatro cursos de Licenciatura em Química de uma universidade pública do Estado de São Paulo, no que tange a articulação da HFC com ensino. Partimos da análise dos Projetos Pedagógicos dos Cursos (PPCs) e dos planos de ensino das disciplinas específicas sobre HFC. Buscamos ainda investigar os docentes que ministram tal disciplina, a fim de entender como sua formação poderia influenciar em sua prática. Para tanto, realizamos primeiramente uma busca nos currículos Lattes, e posteriormente, uma entrevista semiestruturada, com o intuito de aprofundar as informações e entender como conduzem e organizam a disciplina. Utilizamos como metodologia de análise a Análise de Conteúdo (AC). Com base nas análises realizadas, notamos que os PPCs possuem semelhanças entre si, e também com os documentos governamentais. Contudo, a presença de HFC é muito sucinta, focando apenas nas visões de Ciência que se deseja proporcionar, faltando assim maior apropriação dos resultados de pesquisas da área de Ensino de Ciências sobre essa temática. Todos os cursos apresentam uma disciplina específica sobre HFC, no entanto em um deles ela é considerada como optativa. Os planos de ensino analisados não apresentam uma uniformidade, no que versa sobre a organização da estrutura das disciplinas, porém todos fazem uma abordagem sobre aspectos gerais da HFC, sendo que apenas um indica como conteúdo programático a História da Química. Dois, dos cursos, trazem em seu plano de ensino a proposição de discussões da HFC no ensino. Entretanto, fica evidente que a carga horária da disciplina se torna insuficiente para trabalhar com todos os tópicos. Compreendemos assim, que a efetivação dos temas indicados dependerá da formação do docente responsável pela disciplina. Diante disso, temos quatro perfis distintos de professores, em que dois são formados em Química, sendo que um se aproxima mais da área específica da Química, e dois não são formados em Química, mas estão inseridos na área de Ensino. Dos dois cursos que sugerem no plano de ensino a articulação da HFC com o ensino, apenas um faz tal abordagem. Dessa forma, inferimos que a formação do professor influencia nas escolhas que faz durante a sua prática. Notamos que formação específica em HFC é essencial para ministrar tal disciplina, no entanto não há quantidade suficiente de profissionais para isso havendo sobrecarga de trabalho. Diante de tais constatações, buscamos sugerir algumas orientações que possam auxiliar a organização de uma disciplina de HFC que faça articulações com o ensino. / The oncoming of aspects of History and the Philosophy of Science (HPS) to teaching has been discussed as an important approach to scientific literacy, with potential to develop a more substantiated view on the Nature of Science (NoS) by deconstructing its comprehension as a sum of absolute truths, discovered by great isolated geniuses and free from all influences. In this way, such reflections could enable a humanization of science, a development of critical thinking, and an improvement in the understanding of contents and in the teacher formation. This brings us to the teacher education programs courses and the formation possibilities that these have been providing in relation to this theme. Therefore, this research sought to understand the formative profile of four teacher education programs courses in Chemistry of a public university in the State of São Paulo, regarding the articulation of HPS with teaching. We start from the analysis of the Courses' Pedagogical Projects (PPCs) and the teaching plans of the specific HPS disciplines. We also seek to investigate the professors who teach this subject in order to understand how their formation could influence their practice. Thereunto, we first realized a search in the Lattes curriculum, and then a semi-structured interview with them, in order to deepen the information and understand how they conducts and organizes the discipline. We used the Content Analysis (AC) as the methodology approach. Based on these performed analyzes, we noticed that the PPCs have similarities among each other, and also with the government documents. However, the presence of HPS is very succinct, focusing only on the visions of Science that desires to provide and lacking greater appropriation of the results of Science Teaching researches about this subject. All courses present a specific discipline on HPS, but in one of them it is considered as optional. The teaching plans analyzed do not present a uniformity in what concerns the organization of the disciplines structure, but all of them take an approach on the general aspects of HPS, with only one indicating the History of Chemistry as a programmatic content. Two of the courses have in their teaching plan the proposal of HPS discussions in teaching. However, it is evident that the discipline load becomes insufficient to work with all topics. Therefore, we understand that the effectiveness of this indicated topics will depend on the teaching formation of the professor responsible for the discipline. Giving these facts, we have four distinct profiles of teachers, in which two are trained in Chemistry, one of which is closer to the specific area of Chemistry, and two are not trained in Chemistry, but are inserted in the Teaching area. Of the two courses that suggest in the teaching plan the articulation of HPS with teaching, only one makes this approach. In this way, we infer that the teacher formation influences the choices that they make during their practices. We note that a specific formation in HPS is essential to develop this discipline, however there are not enough professionals for it and there is a work overload. In view of these findings, we seek to suggest some guidelines to help the organization of an HPS discipline that makes articulations with teaching.
