A desistência de alunos na licenciatura em física no Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN): causas e sugestões para o combate

This dissertation proposes studying the issue of withdrawal undergraduate in physics at the Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) and collaborate with suggestions for dealing with this problem. The first chapter begins with an overview of two significant problems in the Brazilian educational system: the high dropout rates in degrees in physics and the lack of teachers with specific training in this science. Then, we discuss the relevance of this research to the area of physics teaching, as well as justify its completion as part of a professional master's degree. After, we present a proper definition for the term withdrawal, which is based on the existing problem in the IFRN. And, in the same chapter, we explicitly the focus, the objectives and the methodological aspects of this work. The results obtained in our investigation are presented in next four chapters. In the second chapter of this dissertation, we present: a brief history of the creation of IFRN degree in physics, the functioning of this course and the foundation of classrooms 2004.2 and 2006.1. We also show a kind of map of the withdrawal of the groups investigated (the dropout rate was 84.4% in both groups) and an analysis of the relationship between the curricula of each of them and the number of dropouts. In the third chapter, we display a descriptive statistics of the students which dropout and found that the largest dropout occurred with students who are women, married, parents of one kid; workers, joined with a minimum age of 23 years and completed high school at least 6 years. Then in the fourth chapter, we reveal and discuss the students' reports on the causes of their dropout. From the data presented, we can say that the answer to the question "What was the main reason for your dropout?" Is mainly in personal injury claims: another option for upper-level course and lack of time to devote to the course. In the fifth chapter, we show the results related to teacher s opinions about the phenomenon in question. We detected three main causes for the abandonment, according to teachers: the lack of dedication, the lack of interest and lack of integration in the course. In the sixth and final chapter, we discuss the results and present our conclusion and the proposed report - the product of this dissertation, presented as Annex. This report contains mainly suggestions for curricular and institutional actions that can contribute to reducing the dropout degree in Physics in the IFRN. The main actions suggested are: implementation of the curriculum in disciplines, implementation of programs or actions to combat this poor content of basic training, implementation of specific programs or actions for the student worker, and dissemination of IFRN degree in physics in schools through seminars or workshops

História da ciência como estratégia didática no ensino médio: um breve olhar de conteúdos da óptica

From a critique of aspects of the current teaching of physics, we propose in this paper an investigation into the conceptions of Nature of Science (NOS) submitted by students from the high school level, as well as the inclusion of discussions about some elements of NOS, through the History and Philosophy of Science, understanding them as facilitating strategy for more effective learning of Physics and, more specifically, the contents of optics. Based on the historical period corresponding to Greek antiquity to the mid-nineteenth century, built and applied a teaching unit to a high school class at the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) Ipanguaçu campus. Our teaching unit involved the reading and interpretation of texts with historical content, observation and assembling five experimental activities, among other activities. Data analysis occurred through questionnaires investigative applied before and after the completion of the teaching unit, as well as questionnaires for content present in the texts. Although not significant, the results indicated that the application of the teaching unit allowed the (re) construction of some conceptions about NOS targets students present in our work, and contribute to a better learning content and greater optical science approach and its nature

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

Proposta para uma abordagem do conceito de oxirredução no Programa Nacional de Integração da Educação Profissional com a Educação Básica na modalidade de Educação de Jovens e Adultos Educação Profissional Técnica de Nível Médio (PROEJA)

The National Program of Professional Education Integration with Basic Education for Youngsters and Adults (PROEJA) Technical Professional Education Ensino Médio has opened a new chapter in the history of education in Brazil, making possible the integration of basic education and professional education. This new form of education, which is still in its early implementation, presents a series of challenges to be overcome. Specifically about the teaching of Chemistry, didactic material to match PROEJA s specific needs is practically inexistent. Thus, this work has the purpose of developing didactic material for the teaching of Chemistry for Professional and Technological Education of Youngsters and Adults in the courses of Electronics, Technical Electronics and Maintenance and Support for Computing at Instituto Federal de Educação,Ciência e Tecnologia do Rio Grande do Norte. This material aims at working chemical concepts of oxi-reduction reactions through a theme approach following Freire s conceptions for the teaching of Youngsters and Adults

Entre fronteiras: a escrita imigrante de Julia Alvarez em How the García girls lost their Accents

This master s thesis aims at investigating the way in which diasporic subjects in the novel How the García Girls Lost their Accents (1992) cope with the clash of two cultures the Caribbean one, from the Dominican Republic, and the North-American one, from the U.S., as well as the implications of such negotiations in the lives of immigrants, once it apparently depicts the plight of those who are torn between mother-lands and mother-tongues (IYER, 1993, 46). At the same time, the implications of such negotiations in the lives of immigrants are relevant issues in the writing of Julia Alvarez. For this, there is the analysis of the uses of family memories as one of the main strategies immigrant writers possess to recall their identities. Moreover, this thesis will also consider the language issue for the construction of the immigrant identity insofar as bilingualism is a key factor in the negotiation the García girls must effect between their Caribbean and their American halves in order to understand where they stand in the contemporary world. In order to build a theoretical framework that supports this master s thesis, we list the works of Homi K. Bhabha (1990, 1996, 2003, 2005), Stuart Hall (2001, 2003), Julia Kristeva (1994), Salman Rushdie (1990, 1994), Sonia Torres (2001, 2003) among other contributions that were crucial to the completion of this academic research

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

O ensino de conteúdos de História e Filosofia da Ciência

O presente trabalho de pesquisa consistiu em duas etapas: (i) produção de um Guia de Estudos em que a história das pesquisas sobre a febre amarela (1881-1903) foi usada como subsídio para a discussão de alguns importantes aspectos do processo de produção de conhecimentos na ciência; (ii) realização de experiência pedagógica em que o Guia de Estudos foi aplicado junto a alunos do ensino médio. Os resultados obtidos forneceram evidência da viabilidade do uso da História da Ciência no Ensino de Ciências.

Avaliação de um programa de intervenção de habilidades sociais educativas parentais: um estudo-piloto

Estudos têm apontado relações entre déficits de habilidades sociais educativas de pais e problemas de comportamento de seus filhos. Nesse sentido, esta pesquisa visa a descrever os efeitos de um procedimento de intervenção com pais, o qual pretendeu promover suas habilidades sociais educativas. Participaram dois pais e sete mães, que elegeram o filho com o qual descreveram ter maiores dificuldades de relacionamento. Para a avaliação: 1) das dificuldades dos pais, foi utilizada uma entrevista estruturada, e 2) dos procedimentos de intervenção, foram utilizados: a) questionário de habilidades sociais educativas parentais (QHSE-P) e b) inventário de habilidades sociais (IHS-Del Prette). Os resultados das comparações pré e pós-intervenção do IHS-Del Prette mostraram aumento no escore dos grupos; as comparações do QHSE-P apontaram aquisições de diversas habilidades sociais educativas: expressar sentimentos positivos, agradecer elogios, dizer não e negociar limites. Discute-se a necessidade de procedimentos de promoção de habilidades sociais educativas para ampliar o repertório social parental.

O ensino de procedimentos de política de indexação na perspectiva do conhecimento organizacional: uma proposta de programa para a educação à distância do bibliotecário

A política de indexação deve ser constituída de estratégias que permitam o alcance dos objetivos de recuperação do sistema de informação. O indexador tem a função primordial de compreender o documento ao realizar uma análise conceitual que represente adequadamente seu conteúdo. Utilizando a leitura como evento social/protocolo verbal em grupo, nosso objetivo é contribuir com a literatura sobre política de indexação e apresentar propostas de ensino de política de indexação direcionadas a alunos de graduação e pós-graduação, além de uma experiência de educação à distância com vistas à formação do bibliotecário em serviço. Os resultados obtidos demonstraram que a metodologia pode ser utilizada por sistemas de informação para que se tenha acesso ao conhecimento do indexador. Conclui que o indexador deve ser o alvo de investimento dos sistemas de informação e sugere aos sistemas de informação que a experiência do indexador também seja utilizada como parâmetro para política de indexação.

Percepção Ambiental: Areado - o olhar do povo, a visão da ciência

The objective of this research is to know the conscience, the sensibility and the interperformance's vision man-environment of some residents from Areado's slum, theirs attitudes and motivations to link individual and collectively with their environment seeking ransom the diferences and compare them in relacion of an scientific look. The study to the valorization of experience from individual or from the group consisted of humanist approach of Geography having the phenomenology as underlying philosophy. The theorical formulations manifested from ideas whole, detaching the effort to discipline the use at least these concepts: landscape, space, place and environment. Opposite the importance of knowing the interelation manenvironment, we insert more two concepts: topofilia (felling joins people to the place where they lives) and topophobia, because our preoccupations in the ambit of evironmental question, immediate to the human beings. The research had been developed from interview and percepition workshop, when the interviewed people answered about they understand what are environiment and Areado's environment. The gotten results allow a reflection about the evironmental thought thinking found there, constituting in subsidy to programs of evironmental education that be worried about local problems

Agente comunitário de saúde: perfil adequado a realidade do Programa Saúde da Família?

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Ciência e ética: alguns aspectos

A discussão sobre ciência e ética, se colocada em nível radical, necessita previamente passar pela concepção filosófica de 'ser humano', 'ética' e 'ciência'. Na perspectiva existencialista, o homem é um ser capaz de autodeterminação, ou seja, ser sujeito do conhecimento e da ação. em conseqüência, no campo ético, tudo aquilo que tira ou diminui essa dimensão de sujeito é considerado violência. Por sua vez, a ciência moderna ocidental contém em si um amplo projeto de dominação: da natureza, de si mesmo e do outro. Portanto, uma ciência ética só é possível a partir de uma nova postura diante da própria ciência e dos valores da sociedade construída sob seu signo.
