A Contextual Understanding of the Definition of Science in South Korea

January 2011 (has links)
abstract: Despite the minor differences in the inclusiveness of the word, there is a general assumption among the scientific community that the 'pursuit of knowledge' is the most fundamental element in defining the word 'science'. However, a closer examination of how science is being conducted in modern-day South Korea reveals a value system starkly different from the value of knowledge. By analyzing the political discourse of the South Korean policymakers, mass media, and government documents, this study examines the definition of science in South Korea. The analysis revealed that the Korean science, informed by the cultural, historical, and societal contexts, is largely focused on the values of national economic prosperity, international competitiveness, and international reputation of the country, overshadowing other values like the pursuit of knowledge or even individual rights. The identification of the new value system in South Korean science deviating from the traditional definition of science implies that there must be other definitions of science that also deviates, and that even in the Western world, the definition of science may yield similar deviations upon closer examination. The compatibility of the South Korean brand of science to the international scientific community also implies that a categorical quality is encompassing these different contextual definitions of science. / Dissertation/Thesis / M.S.

Volatile Perceptions: The Power of the Public Sphere to Reshape Science

January 2012 (has links)
abstract: This thesis examines the role of the media and popular culture in defining the shape and scope of what we think of today as "science." As a source of cognitive authority the scientific establishment is virtually beyond dispute. The intellectual clout of science seemingly elevates it to a position outside the influence of the general population. Yet in reality the emergence and evolution of the public sphere, including popular culture, has had a profound impact on the definition and application of science. What science is and how it relates to the life of the ordinary person are hardly static concepts; the public perception of science has been molding its boundaries since at least the 18th century. During the Enlightenment "natural philosophy" was broadly accessible and integrated nicely with other forms of knowledge. As the years passed into the 19th century, however, science became increasingly professionalized and distinct, until the "Two Cultures" had fully developed. The established scientific institution distanced itself from the nonscientific community, leaving the task of communicating scientific knowledge to various popularizers, who typically operated through the media and often used the mantle of science to further their own social or political agendas. Such isolation from orthodox science forced the public to create an alternate form of science for popular consumption, a form consisting mainly of decontextualized facts, often used in contrast to other forms of thought (i.e. religion, art, or pseudoscience). However, with the recent advent of "Web 2.0" and the increasing prominence of convergence culture, the role of the public sphere is undergoing a dramatic revolution. Concepts such as "collective intelligence" are changing consumers of information into simultaneous producers, establishing vast peer networks of collaboration and enabling the public to bypass traditional sources of authority. This new hypermobility of information and empowerment of the public sphere are just now beginning to break down science's monolithic status. In many ways, it seems, we are entering a new Enlightenment. / Dissertation/Thesis / M.A. English 2012

National prestige and in(ter)dependence : British space research policy, 1959-73

Butler, Stuart January 2017 (has links)
From 1960-4 the British government embarked on two large-scale space research programmes to develop satellite launchers. After first being cancelled as a military project in 1960, the Blue Streak missile was converted into the first stage of a British-led European collaborative project to build a three stage satellite launcher (through the European Launcher Development Organisation - ELDO). Born out of the Black Knight warhead re-entry testing vehicle, the independent Black Arrow project aimed to launch small satellites for scientific experimentation. With European collaborations, American scientific knowledge, and an Australian testing site, decisions affecting British space research had wide reaching diplomatic as well as domestic consequences. However, by 1973, both of these programmes had been cancelled. By examining the complex formation of British policy on these two space research projects, I will identify the alliances of actors involved focusing on understanding the role of civil servants, and the domestic, economic, and foreign policy priorities which directed their policy-making. This thesis seeks to address two contradictions raised by British policy on space research, and historical analysis of this period. Firstly, if we accept that Britain was not in decline in this period, the how can the history of two projects which is dominated by their cancellation be explained? Secondly, how British governments could reconcile their policy towards ELDO (threatening to withdraw almost yearly from 1966-73) with their stated aim to accede to the European Communities and their repeated rhetoric that the increased potential for scientific and technological collaboration was a key benefit of British accession? In order to address these contradictions I focus on decisions and decision-makers within government. By tracking policy arguments and options to their very beginnings I show throughout this thesis the way in which individuals frame, shape and direct policy. This thesis provides new insights into the foreign and domestic policy priorities of the four governments in this period by tracking the balance of priorities in policy making in two major space research projects. Close examination of ELDO and Black Arrow highlights that their cancellation is not a symbol of British decline, but instead represent active choices by decision-makers to engage in new areas of research. This supports the work of historians challenging the idea that Britain was in decline in this period, and suggests that cancelled projects should be re-examined.

O erro em sala de aula : subsídios para o ensino do eletromagnetismo /

Souza Filho, Moacir Pereira de. January 2009 (has links)
Orientador: João José Caluzi / Banca: Jesuína Lopes de Almeida Pacca / Banca: André Koch Torres de Assis / Banca: André Ferrer Pinto Martins / Banca: Washington Luiz Pacheco de Carvalho / Resumo: O objetivo central deste trabalho é a Tese de que o processo dialético entre o erro e a verdade, entre a razão e a experiência, propicia a formação de novas zonas do perfil epistemolótico e, consequentemente, contribui para a aquisição de um conhecimento mais sistematizado e mais elaborado. O estudo da epistemologia de Bacharel por meio de suas características: histórica, descontinuísta, dialética e racionalista, e também, pelas noções de obstáculos epistemológicos e perfil epistemológico, fornece subsídios que nos ajudam a compreender a importância do erro e da verdade no desenvolvimento e na aquisição de conceitos. Trata-se de uma pesquisa teórica e empírica. Primeiramente, pro meio de uma recorrência histórica regressamos à história do eletromagnetismo. As concepções deste período se enquadram em duas regiões do perfil: a idéia de ação a distância e noção da teoria de campo. Podemos verificar a importância do erro e da verdade para a formação de uma nova zona do perfil. Em seguida, no campo pedagógico, fizemos uma pesquisa de campo. Elaboramos um curso de extensão universitária denominado "Fundamentos Históricos do Eletromagnetismo" e, aplicamos aos alunos do curso de licenciatura em Física da UNESP/Bauru durante o ano letivo de 2006. Os encontros ocorriam quinzenalmente, nos quais, estudávamos alguns episódios históricos relevantes da temática proposta. A metodologia da análise foi dividida em três etapas do processo de psicanálise propostas por Santos (1998): Na conscientização, aplicamos um questionário logo no primeiro dia de aula. A desestruturação consistiu na gravação dos encontros para análises (gravação, transcrição e interpretação de dados). Esta etapa foi dividida em dois módulos que ocorreram no primeiro e segundo semestres letivos. No primeiro módulo, estudamos o período até a descoberta do eletromagnetismo...

The study of the Bachelard's epistemology through its historical, discontinuous, dialectical and relationalist characteristics and, through the notions of epistemological obstacles and profiles supplies subsidies that help us to understand the importance of the error and of the truth in the development and acquisition of news concepts. This is a theorical and empirical research. First, through a historical recurrence we return to the history of the electromagnetism. The conceptions of this period show two zones of the profiles: Action at a Distance and theory of field. We can verify the importance of the error and of the truth for the formation of the epistemological profiles's new zones. In the pedagogical field, we did a research in the classroom with some students. We elaborated a course of extension. It has been called "Historical Fundaments of the electromagnetism" and, we applied it to the students of the Physical Teaching Course at Unesp/Bauru during the year of 2006. The meeting happened biweekly, in which, we studied some excellent episodes of thematic proposal. The methodology of analysis was divided in three stages of the psychonalysis process proposals by Santos (1998). In the awareness, we applied a questionnaire in the first day of class. The destabilization consisted in the recording of the meeting for analysis (recording, transcription and interpretation of the data). This stage was divided in two modules that had occurred in the first and second semesters of the year. In the first module, we studied the period until the discovery of eletromagnetism and, in the second module, its posterior interpretations...

Jiřina Popelová a moderní česká komeniologie / Jiřina Popelová and Modern Czech Comeniologica Studies

Hajíček, Jakub January 2015 (has links)
Jakub Hajíček The abstract of dissertation thesis Jirina Popelova and Modern Czech Comeniological Studies This dissertation thesis describes the history of Czech and English comeniological studies i.e. the interdisciplinary studies of life, works and legacy of Jan Amos Komensky. The thesis starts with the real beginning of the studies in the 18th century and depicts the history until the Second World War. There is a specific focus on the second half of the 20th century in which the gradual transition to modern comeniological studies takes place - in previous researches Komensky was understood as a great teacher and also as an author of language textbooks. On the other hand, modern comeniological studies interpret him primarily as an original philosopher and theologian whose pedagogical thinking arises from philosophy. Czech-Slovak perspective is consistently applied, and different accents, approaches and also the value of Czech and Slovak comeniological studies are shown in an interesting way. The emphasis is also put on important personalities who were working in the field of comeniological studies e.g. Ján Kvačala, the founder of comeniological studies as a scientific discipline, Josef Hendrich, the most important Czech researcher of the first half of the 20th century, or also on selected personalities...

Uma proposta de articulação entre epistemologia e a história da ciência como fundamentação teórica à construção de episódios em ciência

Machado, Susete Francieli Ribeiro January 2018 (has links)
Esta dissertação de Mestrado visa apresentar os resultados e reflexões obtidos através de uma pesquisa envolvendo a inter-relação entre a História e Epistemologia da Ciência. Teve-se como objetivos principais desta investigação teórica: a construção de uma convergência epistemológica entre as ideias e defesas em Ciência dos filósofos Gaston Bachelard e Imre Lakatos, como também a construção de episódios em Ciência discutidos em grande parcela sob tais olhares histórico-filosóficos. Esta pesquisa possui abordagem qualitativa e quanto aos seus objetivos insere-se como descritiva-reflexiva. Iniciou-se tal investigação realizando um aprofundamento teórico envolvendo as especificidades de cada epistemologia com o objetivo de clarificar o entendimento referente aos pontos estruturantes de cada olhar epistemológico. Em relação ao processo de construção dos episódios em Ciência, realizou-se um levantamento bibliográfico contemplado em maior parte por livros e artigos científicos que tratassem da respectiva temática do episódio, buscando-se uma diversidade de fontes para fundamentar este processo de escrita, com o intuito de valorizar um olhar abrangente sobre a História da Ciência. De modo geral, a construção da convergência epistemológica se fundamentou no que ambas as epistemologias têm em comum que é a própria defesa da História da Ciência por uma natureza epistemológica dinâmica e evolutiva (no que tange à mutabilidade do conhecimento científico), visão normativa, essência dialética e caráter racional objetivo. Desta forma, buscou-se explorar as relações teóricas envolvendo os olhares histórico-filosóficos de ambos os epistemólogos na escrita dos episódios. O primeiro episódio em Ciência visou apresentar e refletir sobre dois programas científicos conflitantes na História da Ciência, os programas flogístico e calórico, os quais marcaram, pontualmente, o período pré-científico da Química e o nascimento das bases teóricas da Química moderna. Já o segundo episódio em Ciência almejou apresentar as principais concepções de matéria desenvolvidas pelos gregos durante a Antiguidade. Os episódios em Ciência produzidos nesta pesquisa valorizam um olhar histórico-filosófico da Ciência através da referida convergência, como também possibilitam uma compreensão da história do pensamento científico por uma natureza conjectural (naturalmente falível) e em constante estado de evolução. Desta forma, defende-se que as epistemologias de Lakatos e Bachelard possuem grande valia ao campo didático científico, pois fomentam concepções epistemológicas contemporâneas e defendem uma Ciência aberta e em constante estágio de devir. Além do mais, os episódios em Ciência podem servir como significativas ferramentas didáticas a abordagens de temas científicos elucidados por olhares que contemplam discussões pertinentes à essência histórico-filosófica do pensamento científico no contexto do ensino. Esta pesquisa evidencia, na base dos seus resultados finais, a necessidade de se buscar valorizar a qualificação da História da Ciência como um importante cerne das discussões dos conteúdos científicos no campo didático, como também a fomentação de um distanciamento em relação às concepções alicerçadas no contexto de ensino que remetem à epistemologia tradicional. / The aim of this Masters dissertation is to present results and reflections obtained from research that involved the interrelation between the History and the Epistemology of Science. The main objectives of this theoretical investigation were the following: the construction of an epistemological convergence between the ideas and advocacies of philosophers Gaston Bachelard and Imre Lakatos, in addition to the construction of Science episodes discussed mostly under such historical-philosophical viewpoints. The research is from a qualitative approach and regarding the objectives is inserted as descriptive-reflexive. The investigation started through further theoretical development involving the specifics of each epistemology with the objective of clarifying the understanding related to the structural points from each epistemological viewpoint. As to the process of construction of the Science episodes, a bibliographical ascertainment was made covering mainly books and scientific articles that dealt with the respective issue of the episode, seeking for source diversity to serve as the foundation for this writing process with the intent of valuing a comprehensive viewpoint of Science History. In general, the construction of the epistemological convergence was founded on where both epistemological share in common, namely the advocacy of Science History itself by a dynamic, evolving epistemological nature (pertaining to the mutability of scientific knowledge), normative viewpoint, dialectic essence, and an objective rational character. This way, an exploration of the theoretical relations was sought that involved the historical-philosophical viewpoints of both epistemologists for writing the episodes. The first Science episode is aimed at presenting and reflecting upon two conflicting scientific programs in Science History, the phlogistic and caloric programs, that were a timely marker of the pre-scientific period in Chemistry and the birth of the theoretical bases for modern Chemistry. The aims of the second Science episode is to present the main conceptions of matter developed by the Greeks in Antiquity. The Science episodes produced by this research value a historical-philosophical viewpoint of Science from the above mentioned convergence, and also allowed for an understanding of the history of scientific thought by a conjectural nature (naturally fallible) and in a constant state of evolution. This way, it is advocated that Lakatos' and Bachelard's epistemologies are of great value to the scientific didactic field by enhancing contemporary epistemological conceptions and advocate that Science be open and in a permanent state of becoming. Furthermore, the Science episodes may serve as significant didactic tools for approaching scientific themes elucidated by viewpoints the include discussions pertaining the historical-philosophical essence of the scientific thought within a teaching context. Based on its final results, this research brings to evidence the need to pursue valuing the qualification of Science History as an important core when discussing scientific contents in the didactic field, as well as enhancing a further distancing in relation go conceptions founded within the teaching context that remit to traditional epistemology.

Perspectivas sobre a evolução histórica do conceito de luz e sua integração com a fotografia para o ensino da óptica

Vieira, Patrese Coelho January 2014 (has links)
A presente dissertação pretende mostrar o desenvolvimento, a execução, a análise e as conclusões provenientes de uma pesquisa de mestrado em Ensino de Física, cuja finalidade esteve em avaliar o impacto de uma abordagem histórica e do emprego da fotografia no ensino de Óptica para o Ensino Médio. Para tal, foi elaborado e aplicado a um grupo de estudantes um minicurso que tratou da evolução histórica do conceito de luz, discutiu tópicos próprios da Óptica, tais como reflexão e refração, e inseriu pontos da Física Moderna e Contemporânea, como a dualidade onda-partícula para a luz e o efeito fotoelétrico. O minicurso também contou com o uso da fotografia pinhole e de câmeras fotográficas digitais por parte dos discentes, visando contextualizar os conteúdos e motivar os alunos para o estudo da Física. Para fins de avaliação da proposta, houve o acompanhamento simultâneo de uma turma de controle, a qual também se ateve ao estudo da Óptica, porém seguiu um ponto de vista tradicional de ensino, sem qualquer discussão histórica e uso de recursos fotográficos. A pesquisa envolveu duas aplicações: a primeira no ano de 2012, em formato de Estudo Preliminar, e outra em 2013, como um Estudo Complementar. A análise qualitativa, complementada por estatística descritiva, indicou que as turmas experimentais apresentaram ganhos de aprendizagem em relação às turmas de controle, ainda que modestos, e que o minicurso representa, em relação à abordagem tradicional, um avanço no sentido de proporcionar um ambiente propício à criticidade. / This dissertation aims to show the development, execution, analysis and conclusions from a masters research in Physics Teaching, whose purpose was to assess what impact the historical approach and the use of photography could pass to the Optics teaching for High School. For that, it was elaborated and applied to a group of students a minicourse, that reported the historical evolution of the concept of light, discussing topics of Optics, such as reflection and refraction, and inserting points of Modern and Contemporary Physics, such as duality wave-particle to the light and the photoelectric effect. The same minicourse also included the use of pinhole photography and digital cameras by students, seeking to contextualize the content and motivate students to study physics. For evaluation of the proposal, there was simultaneous monitoring of a control group, which also adhered to the study of Optics, but followed a traditional view of education, without any historical discussion and use of photographic resources. The research involved two applications: the first in 2012, in the Preliminary Study format, and another in 2013, as a Complementary Study. The qualitative analysis, complemented by descriptive statistics, indicated that the experimental groups showed learning gains compared to the control groups, although modest, and that the short course, in comparison to the traditional approach, represents a breakthrough in providing an environment conducive to critical.

Um levantamento realizado com as atas eletrônicas do 7º, 8º e 9º ENPEC evidenciou ausência de pesquisas com essa temática, o que mostrou a necessidade de sua realização. Assim, a investigação pôde contar com a participação de três professoras de Biologia do Ensino Médio da rede pública, com a realização de entrevistas semiestruturadas para melhor compreender suas concepções e perfis como educadoras, bem como análises do material didático que utilizam. A linha teórica para compreensão e análise dos dados é formada pelas contribuições de Pimenta (1996) e Tardif (2002) quanto ao ensino e o perfil docente e Toulmin (1977) e Gil-Pérez et al. (2001), quanto às visões de Natureza da Ciência. Por meio dos métodos empregados, a visão de História da Ciência mais presente é aquela cronológica e socialmente neutra, apresentando variações entre as professoras e os materiais em estudo. Quanto à Natureza da Ciência, por sua vez, é retratada essencialmente como aproblemática ateórica e acumulativa linear, adquirindo um aspecto empírico-indutivista entre as professoras, assumindo algumas variações por conta de suas trajetórias de vida. / This work aims to identify the conceptions of History and Nature of Science conveyed in Biology teaching for in-service teachers and teaching materials that are used. A survey of the electronic proceedings of the 7th, 8th and 9th ENPEC showed no researchs on this subject, which showed the need for its realization. Thus, the research could count on the participation of three high school biology teachers from public schools, by carrying out semi-structured interviews to better understand their views and profiles as educators, as well as analysis of the teaching materials they use. The theoretical framework for understanding and analyzing the data is formed by the contributions of Pimenta (1996) and Tardif (2002) about teaching and teacher’s profile and Toulmin (1977) and Gil-Pérez et al (2001), for the views of the Nature of Science. Through the methods employed, the most present views of History of Science is those more chronological and socially neutral, with variations between the teachers and the materials under study. As the Nature of Science in turn, is portrayed essentially as aproblematic and atheoretical, as well linear cumulative, being empirical-inductive for the teachers, with some variations due to their life histories.

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

Definitely Directed Evolution (1890-1926): The Importance of Variation in Major Evolutionary Works by Theodor Eimer, Edward Drinker Cope, and Leo Berg

January 2014 (has links)
abstract: This dissertation shows that the central conceptual feature and explanatory motivation of theories of evolutionary directionality between 1890 and 1926 was as follows: morphological variation in the developing organism limits the possible outcomes of evolution in definite directions. Put broadly, these theories maintained a conceptual connection between development and evolution as inextricably associated phenomena. This project develops three case studies. The first addresses the Swiss-German zoologist Theodor Eimer's book Organic Evolution (1890), which sought to undermine the work of noted evolutionist August Weismann. Second, the American paleontologist Edward Drinker Cope's Primary Factors (1896) developed a sophisticated system of inheritance that included the material of heredity and the energy needed to induce and modify ontogenetic phenomena. Third, the Russian biogeographer Leo Berg's Nomogenesis (1926) argued that the biological world is deeply structured in a way that prevents changes to morphology taking place in more than one or a few directions. These authors based their ideas on extensive empirical evidence of long-term evolutionary trajectories. They also sought to synthesize knowledge from a wide range of studies and proposed causes of evolution and development within a unified causal framework based on laws of evolution. While being mindful of the variation between these three theories, this project advances "Definitely Directed Evolution" as a term to designate these shared features. The conceptual coherence and reception of these theories shows that Definitely Directed Evolution from 1890 to 1926 is an important piece in reconstructing the wider history of theories of evolutionary directionality. / Dissertation/Thesis / Doctoral Dissertation Biology 2014
