1. The biography of Crawford Munro (1904-76) describes his early life in Toowoomba and Sydney, and his maturation as an engineer, working for Sydney Water, Sydney Technical College and in the production of Cruiser tanks in World War II. He was a large confident man with a big voice and an optimistic, humorous personality. As the Foundation Professor of Civil Engineering at the University of New South Wales Munro was liberal, fostered humanist studies and developed the School of Engineering with a unique emphasis on water engineering. He recruited excellent staff for research and postgraduate education who led the nation across all phases of hydrology and hydraulics. Munro developed a remarkable, rational solution for flood mitigation at Launceston, and actively promoted research, partly through the Australian Water Research Foundation and the Institution of Engineers, Australia. He was much involved with predicting flood runoff, developing benefit/cost relations for irrigation schemes, which led him into public controversy, and other hydrological projects. Munro’s attempts to raise social consciousness about water problems, his multi-disciplinary approach to the evaluation of water resources and his campaigns for the collection of stream and rainfall data helped provide a better basis for proper planning. In his later years he undertook the first Australian environmental impact study. The concluding chapter outlines a vision for the current management of Australia’s water. Munro posed necessary questions about measuring the supply of water and bringing the demand of water into synchrony with its supply, while providing water security in terms of its availability and quality. He raised the debate about the balance between sustaining environmental flows, utilizing water for agriculture and secondary industry, and maintaining the health of communities. Munro hoped equitable decision making would emerge from public engagement on these issues. 2. Twentieth century science biography in Australia is the province of a group of elite male scientists, whose interests cover wide disciplinary fields; it is focused on popular imagination: health, food and adventure (Antarctica) accounting for fifteen of the seventeen scientists. Empathy for the subject is a significant feature of the nineteen biographers, of whom five are scientists. This small genre is often supported by institutions in small print runs. A key role of biography is to place through science history a more epistemologically plausible version of events. Public discourses of science treated in the essay include conflict about the attribution of scientific discovery, the vocation of the scientist as a contributor to a wider social polity, the light biography sheds on sources of creativity and the evolution of the research and culture of institutions. The biographer attempts to generate a personal portrait of the scientist which conveys authority about the significance and origins of his or her scientific discoveries and their impact in the wider social context. Daniel Söderqvist’s affirmation of the existential approach which ‘emphasizes the freedom and responsibility of the human individual’ resonates with the candidate as expressing characteristics of the lives of many Australian scientists in their passion for intellectual discovery, their motivation to self-empowerment, and their readiness top step outside their social conditioning. This essay extends Söderqvist’s paradigm to the context of Australian science biography and indicates some constraints on its depiction which arise in the practice of writing science biography. Some epistemological issues are raised in the texts, especially when dealing with oral history and family mythology, and thematic, thematic within a chronological framework or chronological structures of the text are compared. The level of detail and context influence the sustainability of the reader’s interest. Case studies of the biographies written by the candidate (Ian Clunies Ross, Samuel Wadham, Allan Callaghan, Victor Trikojus, Raymond Hoffenberg and Crawford Munro) illustrate issues which arise in the writing of science biography. The dominant question is the relationship of the biographer to the subject, and this determines the voice the reader hears. The motivation of the biographer may arise in varying degrees of empathy felt for the subject. The high affinity the candidate had for Clunies Ross and Hoffenberg causes him to offer a defence against the charge of hagiography, and the selectivity and subjectivity of the biographer is evident in the arrangement and presentation of factual material. The motivation of the biographer is additionally directed to the communication of the subject’s research outputs to the wider Australian community, and in the case of Callaghan, Wadham and Clunies Ross there was a specific programmatic function of advancing the status of agricultural science. It is argued that the description of the public life of the subject needs to be complemented from the private life if the biographer is ‘to view the world through the eyes of the subject’.

abstract: At the interface of developmental biology and evolutionary biology, the very criteria of scientific knowledge are up for grabs. A central issue is the status of evolutionary genetics models, which some argue cannot coherently be used with complex gene regulatory network (GRN) models to explain the same evolutionary phenomena. Despite those claims, many researchers use evolutionary genetics models jointly with GRN models to study evolutionary phenomena. How do those researchers deploy those two kinds of models so that they are consistent and compatible with each other? To address that question, this dissertation closely examines, dissects, and compares two recent research projects in which researchers jointly use the two kinds of models. To identify, select, reconstruct, describe, and compare those cases, I use methods from the empirical social sciences, such as digital corpus analysis, content analysis, and structured case analysis. From those analyses, I infer three primary conclusions about projects of the kind studied. First, they employ an implicit concept of gene that enables the joint use of both kinds of models. Second, they pursue more epistemic aims besides mechanistic explanation of phenomena. Third, they don’t work to create and export broad synthesized theories. Rather, they focus on phenomena too complex to be understood by a common general theory, they distinguish parts of the phenomena, and they apply models from different theories to the different parts. For such projects, seemingly incompatible models are synthesized largely through mediated representations of complex phenomena. The dissertation closes by proposing how developmental evolution, a field traditionally focused on macroevolution, might fruitfully expand its research agenda to include projects that study microevolution. / Dissertation/Thesis / Doctoral Dissertation Biology 2017

O presente trabalho trata do uso de analogias em atividades didáticas voltadas às aulas de ciências e, mais especificamente, do uso de analogias em aulas sobre temas de física quântica para alunos do ensino médio. Partimos, então, da aparente contradição que resulta da tentativa de abordar conceitos da física quântica, conceitos estes abstratos e sem relação com a realidade sensível, por meio de um mecanismo representativo que é baseado na comparação entre dois domínios do conhecimento, no qual um deles pertence ao repertório do conhecido (familiar) e o outro diz respeito ao que se deseja conhecer. Nossa principal contribuição, ligada à nossa proposição inicial, se dá na medida em que propomos inicialmente reflexões a respeito do conceito de analogia em três dimensões: a primeira, associada à perspectiva da psicologia cognitiva, na qual a analogia se constitui como elemento central do pensamento e assim da formação dos conceitos em toda a história do sujeito; a segunda, relacionada à epistemologia da ciência, especificamente sob a perspectiva de Henri Poincaré, a partir da qual se apontam basicamente três categorias de analogias (figurativas, mecânicas e matemáticas); a terceira, ligada às atividades didáticas que consideram a analogia como ferramenta de aprendizagem, e que busca, a partir de esforços coletivos presentes na literatura especializada em ensino de ciências, sistematizar o seu uso. A partir de uma ampla leitura das três dimensões supracitadas, propomos uma síntese que nos permita um olhar específico para nosso objeto de pesquisa. A fim de analisar o potencial de nossa síntese teórica, realizamos um ensaio empírico que consistiu na elaboração de episódios criados a partir de aulas de temas de física quântica ministradas a alunos do ensino médio (modelos atômicos, efeito fotoelétrico, dualidade onda-partícula, interpretações da Mecânica Quântica). A metodologia usada na interpretação dos episódios pressupõe que analogias em atividades didáticas podem ser classificadas quanto ao seu nível de elaboração, assim como em aspectos ligados ao seu uso, como o formato de apresentação e de ações prévias. Os resultados nos ajudam a perceber situações de uso de analogias prioritariamente figurativas com alguns casos de analogias mecânicas. A ausência de uso de analogias matemáticas, assim como do formato de apresentação matemático-representativo, nos permite reafirmar o caráter crucial de se investigarem novos \"formatos\" de analogias que sejam adequados à comunicação e ao ensino de conceitos da física quântica. / This work deals with the use of analogies in teaching activities of sciences and, more specifically, with the use of analogies in high school quantum physics courses. Our starting point is the apparent contradiction of attempting to approach the concepts of quantum physics, abstract and deprived of any relation with the sensory reality, through a mechanism of representation based on the comparison of two fields knowledge: a first one which is known and familiar, and a second one which we wish to grasp. Our main contribution lies in our initial proposition to reflect on the concept of analogy from three different perspectives: first, there is the point of view of cognitive psychology, in which analogy appears as central element of thought and therefore of the formation of concepts during the whole history of the subject; second, there is the point of view of epistemology of science, and particularly that of Henri Poincaré who distinguished three basic categories for analogies (figurative, mechanical and mathematical); third, there is the point of view of educational activities, which considers analogies as a learning tool and attempts, through collective efforts manifested in the science education literature, to provide a systematic account of their use. Based on an ample reading along the three aforementioned dimensions, we then propose a synthesis enabling us to adopt a specific look at our object of research. In order to analyse the potential of this theoretical synthesis, we have conducted an empirical test constituted by episodes created within high school quantum physics lectures (atomic models, the photoelectric effect, the wave-particle duality, and the interpretations of Quantum Mechanics). In order to interpret these episodes, the methodology assumes that analogies in teaching activities can effectively be classified according to their level of development and to some aspects of their use, such as the presentation format and the previous actions. The results help us in perceiving how most of the analogies used are figurative, even though there are also some mechanical analogies. The lack of use of mathematical analogies, as well as the absence of the mathematical-representative presentation format, allows us to reaffirm the crucial need of investigating new \"formats\" of analogies, better suited for the communication and teaching of the concepts of quantum physics.

Não há dúvidas de que os campos da Ecologia e da Educação Ambiental estão intimamente relacionados. No entanto, a epistemologia destes dois campos tem mostrado algumas imprecisões na forma e no entendimento de como a Ecologia vem sendo apropriada pela Educação Ambiental, tornando esta relação menos direta do que uma visão superficial possa sugerir. Este trabalho teve como objetivo central compreender as relações entre esses dois campos do conhecimento, por meio de uma análise das pesquisas - teses e dissertações - em EA no Brasil. A partir da questão central \"Em que medida e extensão as pesquisas em EA incorporam e se apropriam de aspectos e conhecimentos da Ecologia\", esta pesquisa propôs-se a: a) Identificar, por meio de uma perspectiva histórica da Ecologia, a evolução dos principais conceitos e questões deste campo científico; b) Analisar as teses e dissertações em EA relacionadas ao campo da Ecologia, tendo como referencial teórico a perspectiva histórica construída anteriormente e referenciais do campo da EA e c) Discutir as implicações pedagógicas dos aspectos da Ecologia presentes nestas teses e dissertações em EA, apontando possíveis contribuições da área da Ecologia para estas pesquisas. Este trabalho insere-se num projeto de pesquisa maior intitulado \"A Educação Ambiental no Brasil: análise da produção acadêmica (teses e dissertações)\", desenvolvido desde 2010, por um grupo de pesquisadores de diversas instituições de ensino superior do Estado de São Paulo (UFSCar, UNESP Rio Claro, UNICAMP e USPRP), que realiza um estudo do estado da arte da pesquisa em EA no Brasil, utilizando o Banco de Teses e Dissertações da CAPES. A análise do conteúdo das pesquisas em EA-Ecologia, que incluiu um universo amostral de 40 teses e dissertações, identificou uma relação ambígua entre esses dois campos, pois ao mesmo tempo em que foram encontradas centenas de menções ao campo da Ecologia, evidenciando assim, a existência de uma relação direta entre eles, constatou-se que a maioria dos trabalhos estabelece relações superficiais com o campo da Ecologia e poucos estabelecem relações diretas e mais aprofundadas com este campo. A explicitação destas relações, bem como, uma análise e discussão das implicações pedagógicas destes resultados para as pesquisas em EA fecham o presente trabalho. / Even though the relation between Environmental Education (EE) and Ecology might seem commonsense, epistemological studies have revealed inaccuracies in the appropriation of ecological elements by EE researchers, making this relation less direct then a superficial analysis could suggest. The main objective of this study is to investigate the interface between EE and Ecology through the content analysis of theses and dissertations produced in the field of EE. From the main question \"To what extent has the research in EE appropriated from elements belonging the field of Ecology\" we attempted to: a- Identify, from a historical perspective, the evolution of the main concepts and questions which embody the field of Ecology; b- Analyze EE dissertations with references to the field of Ecology and characterize these references; c- Discuss the pedagogical implications of the ecological concepts identified in the dissertations, pointing out possible contributions to the research in EE. This study is part of a larger project entitled \"Environmental Education in Brazil: an analysis of the academic production (theses and dissertations)\" involving a group of researchers from different higher education institutions in the state of Sao Paulo (UFSCar, UNESP Rio Claro, UNICAMO and USPRP), working on \"state of the art\" studies based on the CAPES databank of theses and dissertations. The content analysis, based on a sample of forty dissertations, identified an ambiguous relationship between the fields of EE and Ecology. Although there were hundreds of references to ecology related terminologies, most of those represented superficial mentions, instead of a direct relation. The discussions of these relations, as well as their pedagogical implications, are discussed in the conclusion of this study.

O ensino da Física Moderna e Contemporânea (FMC) vem sendo palco para uma ampla discussão nas últimas décadas. No entanto, a realidade escolar ainda se encontra profundamente afastada de uma prática sistematizada do ensino de tópicos relativos a este período de construção do conhecimento científico. Ao contrário dos argumentos apresentados nos documentos educacionais e nas pesquisas acadêmico-científicas, o que ainda se enxerga é uma prática dominada por tópicos associados à física clássica e enviesada por uma visão de ciência profundamente comprometida com o caráter empírico-indutivista de apreensão da realidade. Neste contexto, esta pesquisa buscou promover uma reflexão sobre a dimensão epistemológica do problema de renovação curricular. Para isto, baseou-se em referenciais das denominadas teorias de currículos, compreendendo a constituição dos saberes escolares segundo as reflexões do sociólogo da educação francês Jean-Claude Forquin, e no trabalho epistemológico do filósofo da ciência francês Gaston Bachelard, acerca da novidade essencial do pensamento científico contemporâneo. Coloca-se como hipótese central que a concepção positivista de ciência, dominante na educação científica, vem exercendo enorme influência sobre a forma como discussões e propostas sobre o ensino da FMC tem sido conduzidas - ocasionando um afastamento cada vez maior entre os estudantes e as formas próprias de pensar deste período de extrema importância para a ciência. Para materialização destas reflexões, foram analisadas diversas propostas para o ensino e divulgação da Física de Partículas Elementares no nível médio, apontando que grande parcela delas vem se concentrando em disseminar uma visão reduzida à enunciação da composição da matéria por quarks e da classificação e organização das espécies de partículas. Apontamos para a necessidade de encontrar alternativas para o ensino de física de partículas, tomando seu desenvolvimento histórico como parâmetro de análise. / The teaching of Contemporary and Modern Physics (CMP) have been the stage for a wide discussion in the past few decades. However, the actual school is far away from a systematized practices on teaching topics related to this period of scientific development of knowledge. Contraty to the arguments presented in the educational documents and academic researches, what we\'ve been seen is a practice dominated by topics of classical physics e skewed by a deeply committed view of Science with an empirical-inductive character of apprehension of reality. In this context, this research sought to promote a reflection on the epistemological dimension of the curriculum renewal problem. For this, it was based on references of the curriculum theories, understading the constitution of scholarly knowledge, according to the work of the French sociologist Jean-Claude Forquin, and on the epistemological work of the French philosopher of Science Gaston Bachelard, on the essential novelty of the contemporary scientific thought. The central hypothesis is that the positivist conception of Science, dominant in the scientific education, has been exerting a strong influence in discussions and proposals about on teaching of the CMP - leading to a great distance between the students and the own ways of thinking of this period of for science. In order to materialize these reflections, several proposals for the teaching and dissemination of Elementary Particle Physics in the middle level were analyzed, pointing out that a large number of them have been concentrating on disseminate a view of particle physics reduced as a composition of matter by quarks and the classification and organization of particles species. We\'re pointing to a necessite of finding alternative looks for particle physics teaching, taking its historical development as a parameter of analysis.

O principal objetivo foi entender como o conhecimento científico é construído em um texto de divulgação científica. Para isso foram definidas as seguintes ações: a proposição de um modelo de comunicação que identificou e descreveu as particularidades do corpus escolhido; a construção de um diálogo com uma abordagem epistemológica do corpus que permita entender como a ciência é representada e a busca de evidências dos itens anteriores em textos selecionados. A fundamentação teórica discutiu os modelos comunicacionais existentes na consolidação do conceito de situação de comunicação e contrato de comunicação (CHARAUDEAU, 2014) para entender o lugar da revista Ciência Hoje na mídia, segundo a Semiolinguística. Em seguida, houve uma articulação da referenciação (MONDADA, 2002) juntamente com a epistemologia da ciência para estipular a negociação de significados entre o leitor e o cientista ao considerar o senso comum, para, somente então, construir o conhecimento científico. A metodologia utilizada justificou a escolha do editorial de primeiro exemplar do ano, trouxe os critérios de seleção dos textos e dos trechos a serem analisados. Com esses instrumentos foram selecionadas as introduções de 8 dos 18 textos que compõem o corpus. Os resultados obtidos mostraram que foi preciso modificar alguns itens do contrato de comunicação para descrever adequadamente as condições de contorno da revista Ciência Hoje. A partir da análise realizada com instrumentos da Linguística do Texto foi possível entender como ocorre a construção de um objeto de discurso (MARCUSCHI, 2011) na divulgação científica, em que há uma aproximação entre a linguagem comum e a linguagem científica. Outro resultado a ser destacado é a presença de um plano de texto (ADAM, 2011) recorrente nas introduções selecionadas, que traz uma mesma estrutura argumentativa, embora as estratégias textuais escolhidas pelos autores sejam bastante distintas. Os resultados também mostraram que os cientistas consideram como parte integrante da ciência as emoções, a intuição, o acaso e outros saberes pouco associados à ciência. / The present work investigated Popularization of Science under the view of the Text Linguistics (KOCH, 2009) along with contributions of the epistemology of science (BACHELARD, 1996). The main objective was to understand how scientific knowledge is constructed in popularization of science texts. For this, actions were defined as: a proposal of a communication model that identified and described tje particularities of the chosen corpus; The construction of a dialogue with an epistemological approach of the corpus that seek to understand how science is represented and a search for evidence of previous items in selected texts. The theoretical basis discussed the communication models existing in the consolidation of the concept of communication situation and the communication contract (CHARAUDEAU, 2014) for the Ciência Hoje journal in the media, according to Semiolinguistics. Then there was a reference (MONDADA, 2002) articulation with an epistemology of science to stipulate a negotiation of meanings between the reader and scientist to consider common sense, only then to construct scientific knowledge. The methodology used justified the choice of the editorial of the first release of the year, the selection criteria of the texts and the sections to be analyzed. With these instruments 8 introductions of an amount of 18 texts that compose the corpus were selected to be analysed. The results obtained showed that some items of the communication contract were modified to adequately describe the conditions of framework of the Ciência Hoje journal. From the analysis performed with instruments of the Linguistics of the Text it was possible to understand how the construction of an object of discourse (MARCUSCHI, 2011) in the scientific dissemination occurs, in which there is an approximation between the common language and the scientific language. Another result to be highlighted is the presence of a recurrent text plan in the selected introductions, which has the same argumentative structure, although the textual strategies chosen by the authors are quite different. The results also showed that scientists consider emotions, intuition, chance and other knowledge associated with science as an integral part of science.

One of these concepts which exemplify properly this difficulty in learning or teaching is entropy. This thesis propose the construction of a didactic route which constitute itself a historical and epistemological course to entropy, intending to contribute for teaching this concept as well as other physics concepts. The basic assumption to build this route is that through the historical review of the development of this concept in the way suggested by Bachelard s (1884-1962) epistemology it is possible to make subjects, to be taught and learned, more meaningful. Initially I composed a brief biographical note to give the reader an idea about the issues, interests and reflections, related to science, and how I dealt with them in my private and professional life, as well as the role they played to lead me to write this thesis. The strategy to construct the route to entropy was to split the usual contents of basic thermodynamics in three moments in a way they can constitute epistemological units , which can be identified by the way of thinking in the corresponding moments of scientific knowledge production: a technical and empiricist moment, a rationalist and positivist moment and a post-positivist rationalist one. The transition between each moment is characterized by a rupture with the former way of thinking; however the progress in the construction of knowledge in the area is evident. As the final part of this work I present an analysis based on elements of Bachelard s epistemology that are present in each moment. This analysis is the basic component of the didactic route that I propose myself to build. The way I made this route guide to entropy could contribute to the construction of other didactic routes in physics and other sciences, in a way to unveil hidden meanings and as a tool to humanize scientific knowledge. / A constru??o racional necess?ria ? sistematiza??o do conhecimento cient?fico na f?sica acarreta dificuldades de entendimento de alguns dos seus conceitos. Um conceito que apresenta, de forma exemplar, esta dificuldade - tanto de aprender quanto de ensinar - ? o conceito de entropia. Esta tese prop?e a constru??o de um roteiro did?tico que se constitui num percurso hist?rico e epistemol?gico para a entropia, com a inten??o de contribuir para o ensino deste conceito e, de maneira geral, para o ensino da f?sica. A premissa b?sica para a constru??o do roteiro ? que, atrav?s de uma revis?o hist?rica do desenvolvimento do conceito, nos moldes sugeridos pela epistemologia de Bachelard (1884-1962), ? poss?vel tornar mais significativo o conhecimento a ser ensinado e aprendido. Inicialmente fiz um pequeno memorial com o objetivo de dar ao leitor um panorama das inquieta??es, interesses e reflex?es que teci em minha vida pessoal e profissional com rela??o ? ci?ncia e seu papel e que me levaram a construir esta tese. A estrat?gia para a constru??o do roteiro foi dividir o conte?do usual da termodin?mica b?sica em tr?s momentos de modo que estes se constituam em "unidades epistemol?gicas", ou seja, momentos que possam ser identificados a partir do pensamento predominante na constru??o do conhecimento cient?fico: Um momento t?cnico empirista, um momento racionalista positivista e um momento racionalista p?s-positivista. A transi??o de um momento para outro implica uma ruptura com o pensamento anterior. Entretanto, o progresso na constru??o do conhecimento na ?rea ? evidente. Como parte final do trabalho, apresento uma an?lise de elementos da epistemologia de Bachelard presentes em cada momento. Esta an?lise ? o componente fundamental do roteiro did?tico que me propus a construir. A forma como constru? este percurso para a entropia pode contribuir para a constru??o de percursos outros, na f?sica ou em outras ci?ncias, com vistas a desvelar significados e humanizar o conhecimento cient?fico.
