Ensinando sobre a natureza da ciência: uma abordagem explícita e contextualizada a partir da história do vácuo

In last decades, the importance of including the contents of the Nature of Science (NOS) in Science Education has been emphasized. Several studies have focused on investigating the conceptions of NOS, supported by students and teachers, as well as design, implement and evaluate proposals that aim to provide a reflection on this theme in the educational context. Considering the complexity of such content, studies indicate the need for explicit and contextualized approaches and the History of Science (HS) is one of the possible paths to this inclusion. We started from the premise that, through a historical study, that aims to discuss the meaning and the basis of our "beliefs", we can know the process of building on what we "believe" and better understand its meaning. This thesis is part of this perspective, proposing to explore the History of the Vacuum, a themed high didactic potential still little used, in order to collaborate with the teaching content of NOS. We present actions on different fronts that originated three products in the context of this research. On the first front, we insert the research and production of instructional materials (three historical texts) to subsidize people interested in the implementation of HPS for educational context through this material. The relevance of this front is justified by the existence of gaps with regard to the production of such material for the context of teacher training. However, we consider that the preparation of instructional material of good quality and accessible does not guarantee that these resources will be used, if they will not be accompanied by discussions in teacher training, on how to use them, contexts and obstacles to be faced. The second part presented refers to the organization and implementation of a workshop for undergraduate students in physics and physics teachers, considering the instrumentalization of these individuals to the preparation and use of teaching strategies to approach aspects of NOS through episodes of History of the Vacuum, as well as the preparation of the text orientation for people interested in implementing the instructional material for secondary education. This guidance text contemplates the difficulties anticipated by the literature of the area and the main challenges faced by the participants about the didactic transposition of HPS for the educational context they were noted during the workshop. The relevance of this second front, in particular, is justified by the existence of gaps with regard to the inclusion of the theme of NOS and the HPS teacher training

Do cientista ao ativista: os problemas da ciência do texto e uma solução revolucionaria na obra de Terry Eagleton

The literary critic Terry Eagleton obtained notoriety in academic circles when he was recognized intellectually for his bestselling book Literary Theory: An Introduction. In this book, the English author boldly proposes the end of literature and literary criticism. However, Eagleton proposed years before, in his book Criticism and Ideology (1976), a scientific system of analysis of literary texts, which seemed less radical, both in theory and in method, than in his later theoretical proposal. Based on this, the objective of this dissertation is to present the English literary critic´s initial method, explaining the reasons that led him to abandon his initial project - of develop a method of analysis of the literary text on a Marxist scientific perspective - and to propose, in the following years, in his most famous book and others, a revolutionary vision that would go beyond textual analysis and make literary texts have a practical intervention in society. Finally, we explain what would be his idea of revolutionary criticism

Memórias midiatizadas: percepções sobre ciência reconfiguradas a partir do consumo midiático

This piece focuses on the issue of media in the contemporary context, taking for its object the sociocultural phenomenon of mediatization‟, understood as the dilution of media culture in the everyday life, according to the perspective from Fausto Neto (2008) e Sodré (2002). This phenomenon is viewed from the angle of reception, that is, one that considers the individuals as pro-actives in this dynamic. The media culture is perceived as a fundamental element in the process of social structuring, and also is taken as a symbolic arm of great importance for the elaboration of the notion of reality as it interferes with the flow of information. Thus, we emphasize the process of symbolic consumption that we do with media content (Canclini, 1999), through a dynamic of appropriation and reframing, given from the interweaving of the meanings proposed with extra-media elements, recaptured from the perspective of mediations, by Barbero (2006), which concerns the articulation of the contents we appropriate from media with interactions from other social practices. We also consider the dimension of memory according to Sarlo (2007) and Halbwachs (2004) in order to, through speeches made in its scope, reach empirically the phenomenon of mediatization‟, and overlapping it, the media consumption on a specific theme, "science". Nevertheless, in terms of field work, we use the technique of in-depth interviews, so that the speech of our interviewers was our corpus. Through their narratives, speeches considered by us as memory-related, we visualize the dynamics of media consumption on given topic. At the level of conclusions, we realize that mediatization‟ as a phenomenon occurred, but its flows and orders showed discontinuities and pluralities not initially conceived; regarding the consumption of science through media, we see hybrid perceptions by our respondents, that is, one that include both elements aligned with the positivist conception of science - which we consider to be the view of science proposed by the media and elements that would contradict this view

Para além da ciência: por uma gaia ciência

Em A gaia ciência Nietzsche irá abordar a ciência, especificamente a sua finalidade, sob uma perspectiva crítica, apontando a necessidade de um conhecimento científico mais humano e menos mecanicista, uma ciência mais próxima à arte, que ao invés de descobrir verdades, se ocupe em criar novos valores, visões e perspectivas. Ao longo da obra fica evidente a intenção do filósofo em não apenas criticar a ciência, mas também, conceber um novo método, uma nova ciência, uma gaya scienza, em alusão à arte dos trovadores medievais. Objetiva-se, com isso, unir vida e conhecimento como partes constituintes de um mesmo processo, fazendo da busca pelo conhecimento, não apenas um ócio ou profissão, mas, sobretudo, um meio de vida. Nietzsche anseia por uma ciência que não se enquadra nas categorias de verdadeiro ou falso, pois o seu valor é diferente do valor da verdade, seu valor maior é a máxima potencialidade da vida em todos os seus aspectos

Ciência e racionalidade em Thomas Kuhn

The work aims to explore the impact that Thomas Kuhn‟s philosophical work had on the philosophy of science, especially on the common idea of scientific rationality. Besides this, it aims to make clear the position of the author about his understanding of what is to be rational in science. In order to achieve this goal we start giving a panoramic view of the philosophical scientific scene of the first half os the twentieth century, to evince the main character of the concept of rationality more accepted at Kuhn‟s time. In a second moment we show how the ideas of this author contrast with that concept, which gives rise to a series of criticisms of irrationalism. Lastly, we show how Kuhn circumvents these accusations by pointing to a new rationality concept, through which we can conciliate his philosophy with a description of the rational development of science

Evolução da terminoliga princípio contábil baseada na Escola Norte-Americana
