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

Pré-fabricados lingüísticos: estrutura e funcionamento de sintagmas verbais idiomatizados - por uma abordagem cognitivo-funcional em sala de aula

This work aims at under the cognitive-functional perspective describing, inside the vast domain of the linguistic prefabs, the structure and the functioning of the Idiomatic Verb Phrases (SVIs), produced by speakers of the Portuguese from Brazil, located in Natal (RN). From the functionalist presupposition that the language is used essentially to assist to communicative demands, it is observed that its morphologic-syntactic structure is conditioned to the inherent pragmatic vicissitudes to the verbal interaction of subjects, socially heterogeneous and historically established. It is focalized, in the composition of SVIs, the relationships VT + OD (transitive verb + direct object), characterizing the syntactic-semantic nature of the verb and of the respective verbal complement. Those verb combinations + complement can be interpreted as lexical structures, reflexes of the idiomaticity inherent to conventional constructions already systematized in the users' of the language cultural repertoire. It is sought, still, to glimpse the cognitive and discursive motivations pertinent to that linguistic phenomenon. In the investigative process, are analyzed exclusive data of speech collected in Corpus Discurso & Gramática a lingua falada e escrita na cidade do Natal, organized by Furtado da Cunha (1998). The adopted methodological procedures configure as methods of empiric analysis and use of the intuition, being emphasized the qualitative approach (explanatory) of the data with quantitative support of statistical indicators. It shows, finally, a grating of didactic suggestions on SVIs, for Portuguese's classes, as subsidies to the educational practice in the Medium Teaching and in the course of Letters.

Projetos de letramento na educação de jovens e adultos: o ensino da escrita em uma perspectiva emancipatória

This ethnographical research-action is included in the Applied Linguistics area and its study object is related to literacy projects (KLEIMAN, 2000), since they bring a new sense to the literacy practices in school and emphasizes the agentive writing character and the role of the discursive genres in the formation of literacy agents who aim at the action and the social change. Considering the emancipatory potential that these didactic organizations have in the civic literacy of those who live in social risk and vulnerability situations our aim in this investigation is: to reflect about the role of the redefinition of the literacy school practices and investigate how the action of teachers and students as literacy agents occur. The specific aims are: to promote literacy events which encourage the writing practice for the action and social change; to comprehend how the identity construction of the literacy student-agent occurs by the reflection of its agency process in the literacy projects; to identify teaching strategies and procedures which enable the development of emancipatory language practices; to investigate the axiological values constructed by the learners in and about the writing work in literacy projects. Our discussion is based on the language conception supported by Bakhtin (BAKHTIN/VOLOSHINOV, 2000; BAKHTIN, 1990, 2003); in literacy studies (KLEIMAN, 1995; BAYNHAM, 1995; BARTON; HAMILTON; IVANIC, 2000, LAZERE, 2005); on critical studies which defend the idea that the texts are ideological instruments able to give power to the individuals (MCLAREN, 1988, 1991, 1997, 1999, 2000, 2001; FREIRE, 1971, 1978, 1979, 1982, 1992, 1996, 2001a, 2001b, 2009; GIROUX, 1983, 1986, 1990, 1992, 1997, 1999, 2003; APPLE, 1989); on the social genre approach inspired by the New Rhetoric (BAZERMAN, 2005, 2006, 2007; MILLER, 1984, 2009). The data were generated between 2006 and 2010 in the Youth and Adult Education (YAE), in public schools in Natal-RN. The research permitted us to deduce, firstly, that the redefinition of the work with discursive genres provide the learner to read and write to act discursively in the social world, earning, thus, empowerment, autonomy and emancipation; secondly, that involving the students in literacy projects goes beyond didactic competence related to specificities and content domain. It is necessary that the teacher is certain about to whom, what, why and how to teach and that he/she gets a reflexive posture, becoming a learner as well; thirdly, that through the literacy practices which were developed, the collaborators of the research have constructed a more conscious and a more critical view in relation to the language and to the world where they live through the social-political writing and they have improved as interventive and politicized citizens

Marcadores da organização do padrão discursivo narrativo: uma abordagem funcional centrada no uso

This thesis has as its object the Markers Organization Standard Narrative Discourse (MON), from its occurrence in oral and written corpora of different realizations of narrative discourse, considering its locus of occurrence in the narrative and discursive functioning. The research is guided by the Functional Linguistic Usage-Based, approach to which the organization of language is directly linked to the user experience, so that grammar is shaped by discourse. We examined only the narrative portions of Experience Reports, Tales and Legends in the oral and written, as follows: 3 inquiries Corpus Reports Remaining Quilombo (RN); 11 Corpus Legends legends of the Amazon, 14 Tales of Corpus Tales Brazilians and 21 Reports of experiences of Corpus and Discourse Grammar, with about 10,000 words in each corpus. A total of 22 markers were identified, which were: (1) classified according to the locus of occurrence in the narrative structure, as Labov (1972), (2) associated, according to the type of pattern that occur in narrative discourse, (3) described from the discursive function they perform. The research has relevance to the extent it is based speech analysis and offers proposals for productive teaching of mother tongue in which students and teachers can, grounded in language studies, consider living language, as an object of study, based on the National Curriculum Guidelines (OCN) and making use of New Technologies of Information and Communication (NTIC)

Manual do professor, muito prazer em (re)conhecê-lo! Uma análise sociorretorica do gênero

Esta pesquisa de natureza documental e etnográfica se insere no campo da Linguística Aplicada, tendo por objeto de estudo o Manual do Professor, que acompanha o livro didático de Língua Portuguesa, e por objetivo geral (re)conhecer os aspectos sociorretóricos do gênero Manual do Professor. O interesse desta tese está concentrado no uso situado desse gênero, a partir do qual se observam seus aspectos sociorretóricos, a saber: o que está posto no produto, o ambiente de interação onde é encontrado e como é visto por seus usuários em potencial. Em um primeiro momento, produzimos um quadro epistemológico que nos permitiu, dentre outros reparos, (i) compreender gênero textual como ação retórica tipificada baseada numa situação retórica recorrente e (ii) obter um panorama dos programas de governo voltados para a avaliação de coletâneas didáticas, nos quais encontramos aspectos indispensáveis a um Manual do Professor. Os aportes teóricos adotados neste estudo referem-se à concepção sociorretórica dos estudos de gênero textual à luz, sobretudo, de Johns et al. (2006), Bazerman (2011) e Miller (2011). Em um segundo momento, sob o viés da abordagem sociorretórica, procuramos definir o Manual do Professor como gênero textual e apresentamos os aspectos retóricos encontrados nas amostras que analisamos, considerando a organização constitutiva, o contexto de uso desse gênero e as percepções de seus usuários autores e professores. A geração de dados deu-se inicialmente a partir da seleção de três exemplares de Manuais de coletâneas didáticas adotadas no IFRN; em seguida, no sentido de reconhecer as percepções dos usuários desse gênero, realizamos grupo focal com professores e entrevistamos o coautor de uma das coletâneas. Para análise dos dados, elegemos o método etnográfico de análise de gêneros postulado por Reiff (apud JOHNS et al, 2006), que nos permitiu analisar o objeto de estudo em contextos autênticos de uso do gênero. Nossos resultados mostram que o Manual do Professor está inserido num sistema de gêneros e no sistema de atividades profissionais de domínio do professor e não se limita apenas a explicar como está organizado o livro didático do aluno. Outros sete propósitos foram observados, dentre os quais se encontram: possibilitar ao docente uma reflexão sobre a sua prática de ensino e sugerir caminhos para a melhoria do processo de ensino-aprendizagem. Acreditamos que esta pesquisa poderá estimular professores, em relação à importância (e não obrigatoriedade) de consultas periódicas aos Manuais; autores, no que se refere a estabelecer uma interlocução mais pessoalizada com seus leitores em potencial e no sentido de esclarecer ainda mais as facetas do livro didático; e editoras, sobretudo no que tange a recursos de editoração, para que o Manual do Professor se torne mais atrativo

Considerações sobre metodologia interativa aplicada à disciplinas de química orgânica de alguns cursos da UFRN

The aiming of this work is linked to chemical education, focusing organic chemistry classes of Chemical Engineering, Pharmacy and Zootechny graduate courses of the Federal University of Rio Grande do Norte. For that, teaching-learning process related to basic chemical subjects which support the understanding of organic chemistry concepts was evaluated in a research period of two years. The education proposal linked to the theoretical content of the cited classes, pointed out the process of knowledge construction, in which educational commitment as well as dedication in the teaching-learning process was also valued. In that approach several didactic tools were applied, among them scientific articles were used as supplementary studies of the basic organic chemistry concepts and related. The acceptability of students, as well as their motivation, performance and learning process was justified by the data collection of the applied teaching methodology. The acceptability and commitment of the students facing this teaching interactive approach, which transversely contributed to the intellectual maturity growth of the students, as well their professional development, were evidenced by satisfactory obtained results that will be herein discussed

Protozoários de vida livre em dois trechos da bacia hidrográfica do rio pirangi (RN): relações com a educação em ciências e preservação

The vast hidric wealth of Brazil gets its watersheds more susceptible to impacts that compromise the water quality, affecting the ecosystem stability of aquatic environments. The decrease in the quality of water resources also results in a decrease of its multiple uses, especially in tourist areas of the coast, where the continuous flow of people to these sites increases even further the probability of inappropriate behavior of both tourists and local residents. Studies regarding the microbiological communities are still scarce, especially on the free-living protozoa that play unique roles in the food chain of aquatic ecosystems. Due to the large role played by this group of microorganisms in aquatic environments, the present study aimed at identifying the genus and species of free-living protozoa present in two sections of the Pium River, east coast of Rio Grande do Norte, making an association between the its occurrence and trophic conditions of the environment in which they are, also checking the bioindicator capacity of these organisms in water quality. It also aimed to conduct a survey with students to identify the main difficulties regarding the knowledge of free-living protozoa and hydric transmission diseases in two public schools near the river studied in the Pium district, county of Parnamirim. The survey was analyzed by means of questionnaires at both schools. Students identified several activities developed Pium river, highlighting its multifunctionality and importance to the region. A total of 76 taxa of free-living protozoa was recorded, of these, 33 were ciliates, 19 flagellates and 24 sarcodia. The spatial and temporal patterns of these organisms to both points studied revealed the bioindicator potentiality of some effective species identified. However, knowledge about the free-living protozoa proved quite lagged, presenting misconceptions that show them as pathogenic organisms exclusively, totally disregarding their ecological role. In order to remedy the flaws existing in students in relation to the functional role of protozoa, workshops were planned on these microorganisms while also addressing issues related to hydric transmission diseases through lectures, recreational activities and interactive presentations. These practical activities of Science Education had the goal of bringing students the context of local water resources, aiming to promote a greater clarification regarding of the functional role of free-living protozoa in aquatic environments

Uma ferramenta didática para ajudar na fixação dos conceitos introdutórios de análise combinatória

Humans, as well as some animals are born gifted with the ability to perceive quantities. The needs that came from the evolution of societies and technological resources make the the optimization of such counting methods necessary. Although necessary and useful, there are a lot of diculties in the teaching of such methods.In order to broaden the range of available tools to teach Combinatorial Analysis, a owchart is presented in this work with the goal of helping the students to x the initial concepts of such subject via pratical exercises

O erro produzido pelo aluno no contexto pedagógico: uma luz ou uma pedra no meio do caminho?

Student’s mistakes as viewed in a didactic and pedagogical perspective are a phenomenon inevitably observed in any context in which formal teaching-andlearning processes are taking place. Researchers have shown that such mistakes are viewed most of the times as undesirable and often as a consequence of lack of attention or poor commitment on the part of the student and rarely considered didactically useful. The object of our reflections in this work is exactly those mistakes, which are born in the entrails of the teaching-and-learning processes. It is our understanding that a mistake constitutes a tool which mediates knowledge and may therefore become a strong ally of the instructor’s actions in her/his teaching tasks and thus should be taken into the teacher’s best consideration. Understanding a mistake as so, we postulate that the teacher must face it as a possibility to be exploited rather than as a negative occurrence. Such an attitude on the part of the teacher would undoubtedly render profitable didactic situations. To deepen the understanding of our aim, we took a case study on the perception of senior college students in the program of Mathematics at UFRN in the year 2009, 2nd term. The reason of this choice is the fact that Mathematics is the field presenting traditionally the poorest records in terms of school grades. In this work we put forth data associated to ENEM1 , to the UFRN Vestibular2 and the undergraduate courses on Mathematics. The theoretical matrixes supporting our reflections in this thesis follow the ideas proposed by Castorina (1988); Davis e Espósito (1990); Aquino (1997); Luckesi (2006); Cury (1994; 2008); Pinto (2000); Torre (2007). To carry out the study, we applied a semi-structured questionnaire containing 14 questions, out of which 10 were open questions. The questions were methodologically based on the Thematic Analysis – One of the techniques for Content Analysis schemed by Bardin (1977) – and it was also used the computer program Modalisa 6.0 (A software designed by faculties the University of Paris VIII). The results indicate that most of the teachers training instructors in their pedagogical practice view the mistakes made by their students only as a guide for grading and, in this procedure, the student is frequently labeled as guilty. Conclusive analyses, therefore, signal to the necessity of orienting the teachers training instructors in the sense of building a new theoretical contemplation of the students’ mistakes and their pedagogical potentialities and so making those professionals perceive the importance of such mistakes, since they reveal gaps in the process of learning and provide valuable avenues for the teaching procedures.

Cenário da produção acadêmica em história da matemática no ensino de matemática: uma análise reflexiva das teses e dissertações (1990-2010)

This research aims to make a reflective analysis about the academic production originated in the stricto sensu post graduation programs in the country, produced in the period of 1990 to 2010, in the field of History of Mathematics, especifically on works about the History of Mathematics in Mathematics education and that present pedagogical proposals that make use of the History of Mathematics in order to teach Mathematics. Defending the thesis that the researches on mathematics education with goals turned to the use of didactic proposals related to the history of mathematic that take in consideration the coherency between epistemological aspects inherent to mathematics history and anthological elements materialized on the conceptions of mathematics and mathematics history and of apprenticeship (implicitly or explicitly exposed) may originate significant contribution to the field of history of mathematics on education. Among these, nine were Master’s Degree dissertations and five PHD’s theses. The reflective analysis was accomplished from two matrixes; one from theoretical nature and the other, ontologic nature, elaborated from the pretexts of Sanches Gamboa, about the epistemological analysis from academic production in the field of Mathematics Education and the following theoretical perspectives in the field of History of Mathematics Education, that are: linear evolutionary theory, structural construtivist operative, evolutionary discontinuous, historical and socialcultural investigation and the use of activities estimulating the usage of verbal and nonverbal expressions. These perspectives were based on the works of Miguel and Miorim, Mendes and Radford. As results, we have detected some established dissonances between the categories related to theoretical and ontologic levels and the pedagogical proposal presented in these researches. On the other hand, we have discovered works that are able to establish consonances between the theoretical and ontological elements and the presented pedagogical proposal. These works carry significative contributions to the field of History of Mathematics applied to Mathematics pedagogical practice, inclusively presenting significative theoretical elements to the production of knowledge recognized as scientific in the Mathematics field

Desenho de deficiência visual: uma experiência no ensino de artes visuais na perspectiva da educação inclusiva

Over the past 30 years, Art Education in interface with disabilities has been a subject of increasing interest in research in academia, especially with regard to Special Education, but still has some shortages in terms of socialization studies to discuss this type of teaching from the perspective of inclusive education. In this scenario, this paper presents an analysis from the field of teaching Visual Arts in the context of school inclusion, with emphasis on teaching drawing to the visually impaired. The conducted literature indicates a number of authors who discuss teaching drawing to people with visual disabilities, who are dedicated primarily to the Special Education context. In this sense, the shortage of research that discuss this teaching from the perspective of inclusive education, this research aimed at the inclusive approach to teaching drawing in the school context. Thus, the aim of this study was to develop a proposal for a pedagogical intervention in Visual Arts, with reference to drawing and its construction process, with the participation of seeing and unseeing students. Therefore, the methodological approach, which was qualitative, was the intervention research, in the light of the Bakhtinian principles of dialogism and otherness, with exploratory study characteristics. The locus of the research was the State School Admiral Newton Braga Faria, which is located in Alecrim, on the East Zone of Natal / RN and is near the Institute for Education and Rehabilitation of the Blind - IERC / RN. The class chosen for intervention was the 7th grade “C” afternoon shift, which had children aged 12 to 16, with 27 students enrolled, three students with disabilities: 02 blind girls and 01 deafblind boy with light hearing and visual loss. As interlocutors of the research, we could also count on the Art teacher who served as a collaborator, as well as teacher in the school’s Multifunction Resource Room. The instruments and research procedures were observation, semi-structured interview, field diary and the photo / video recording. In the development of research, we conducted 10 workshops with multisensory teaching sequences, articulating the physical, tactile and graphical expressions as intrinsic to the reading and production of drawing for both seeing and unseeing students. The process and data built on research allowed for a reflection on cultural experiences with drawing in the school context and on the interactions between seeing and unseeing students in the production and analysis of tactile-visual drawings. They also point out the construction of a teaching approach to drawing, in the context of the common class, from educational workshops that enable artistic and aesthetic interactions from the perspective of school inclusiveness. Thus, we argued that the mobilization of the tactile, physical and graphical expressions can be adopted in a multisensory approach that enables a pedagogical focus that involves all students and is not restricted to the presence of students with visual impairment.

Correspondências científicas como uma relação didática entre história e ensino de matemática: o exemplo das cartas de Euler a uma princesa da Alemanha

Lettres àune Princesse d'Allemagne sur divers sujets de physique et de philosophie (Letters to a Princess of Germany on various topics of physics and philosophy) is the work taken as an object of study of this thesis. It is a literary success written in the eighteenth century by the Swiss mathematician and physicist Leonhard Paul Euler (1707-1783) in order to meet a request from the Prussian king, Frederick II, the Great (1712-1786) to accept to guide the intellectual education of his niece, the young princess Anhalt-Dessau (1745-1808). The method of teaching and learning through letters elected to the education of the German monarch resulted in a collection of 234 matches in which Euler theory is about music, Philosophy, Mechanics, Optics, Astronomy, Theology and Ethics among others. The research seeks to point out mathematical content contained in this reference work based on the exploitation and adaptation of original historical works as an articulator of development activities for teaching mathematics in basic education and in accordance with the National Curriculum Parameters of Mathematics (NCP) work. The general objective point out the limits and didactic potential of Lettres à une Princesse d'Allemagne sur divers sujets de physique et de philosophie as a source of support for teachers of basic education in developing activities for teaching mathematics. The discussions raised point to concrete possibilities of entanglement between the extracted mathematical content of the bulge of the work with current teaching methodologies from resizing the use of letters according to Freire's pedagogical perspective of the correspondence, and especially the use of new communication channels in the century XXI, both aimed at dialogue and approximation between those who write and those who read.

Elaboração de ferramenta computacional para aprendizado da anatomia do pescoço

The teaching-learning process requires a constant search on the part of educators for didatic innovations aimed at improving learning. Among these are technological innovations our students are familiar with. In human anatomy teaching, these innovations are increasingly important, since the need for “mechanizing” many structures may make learning tiresome and nonstimulating for students. The search for new technologies may make this process simpler. Another important issue is the need to constantly emphasize applying the knowledge in question, in order for students to better understand the meaning of learning. Accordingly, this project aims to develop an interactive tablet application for neck anatomy. This application will function as a guide to dissection, containing text, photographs, drawings and videos, distributed systematically, with a script emphasizing the clinical and surgical importance of neck anatomy.

Construção e avaliação de uma unidade de ensino potencialmente significativa para o conteúdo de termoquímica

Nos dias atuais, oferecer uma educação para o exercício da cidadania é função primordial das políticas públicas educacionais, conforme estabelece a constituição brasileira e a legislação de ensino. Essa função vem sendo defendida por muitos professores no Ensino Médio, atribuindo-se a disciplina de Química o papel de proporcionar um ensino crítico, participativo, reflexivo e humano. Segundo os documentos oficiais brasileiros para o Ensino de Química, o estudo do conceito de energia deve favorecer o desenvolvimento de competências para que o aluno compreenda a produção e o seu uso em diferentes fenômenos e possam interpretá-los de acordo com modelos explicativos, além de saber avaliar e julgar os benefícios e riscos da produção e do uso de diferentes formas de energia nos sistemas naturais construídos pelo homem, articulando com outras áreas de conhecimento na procura de promover a interdisciplinaridade. As unidades de ensino potencialmente significativas (UEPS), tomam como base um conjunto de teorias de aprendizagem que tem o intuito de promover um ensino com base na aprendizagem significativa e podem ajudar os estudantes nas diferentes relações que um conceito pode ter. Neste sentido, o estudo do conceito da energia a partir do trabalho com UEPS, pode ser uma importante proposta que favorece um ensino de Química na perspectiva construtivista. Assim, o objetivo deste trabalho é construir e avaliar uma proposta didática para o conteúdo de termoquímica na perspectiva das unidades de ensino potencialmente significativas de Moreira com alunos do Ensino Médio de uma escola pública do Município de Campina Grande-PB. Inicialmente a UEPS foi avaliada por 22 professores em formação inicial de duas instituições públicas de ensino superior. Em seguida, ela foi aplicada para 15 alunos do 2° ano da Escola Estadual de Ensino Médio Prof. Raul Córdula, localizada na cidade de Campina Grande-PB. A coleta dos dados para os professores em formação inicial teve como base um instrumento de validação de elaboração de unidades didáticas baseada na Engenharia Didática proposta por Artigue (1996 apud Guimarães e Giordan, 2011). Já para os alunos do ensino médio, os dados foram coletados no decorrer da UEPS e a avaliação final sobre a proposta didática ocorreu através de um questionário tomando como base a escala de Likert e o uso de mapas conceituais. Para a descrição dos dados, foram utilizados os pressupostos da análise de conteúdo de Bardin. Como produto educacional foi elaborado a Unidade de Ensino Potencialmente Significativa e um DVD contendo orientações de como trabalhar com a proposta. Os resultados deste trabalho apontam uma avaliação positiva quanto à proposta de ensino elaborada para a Educação Básica, onde se observa através do instrumento de validação aplicado, que a maioria das respostas atribuídas pelos professores, ficou entre os itens suficiente e mais que suficiente. Em relação aos momentos de aprendizagem dos alunos do Ensino Médio durante a aplicação da UEPS, foi possível observar que a proposta gerou motivação no processo de ensino e aprendizagem dos conceitos da termoquímica, como também se percebe que os mapas conceituais apresentados pelos alunos apresentaram mais proposições conceituais em uma segunda tentativa de elaboração, logo a proposta de ensino foi aprovada por mais de 90 % dos estudantes do nível médio. Portanto fica evidente que a proposta didática contribuiu no processo de ensino aprendizagem, despertando interesse e motivação nos estudantes pelo conteúdo de Termoquímica.

Formação docente para a inserção da história e filosofia da ciência no ensino: textos histórico-pedagógicos em discussão

The present dissertation focuses on specific problems in the educational context: challenges in the construction of historical narratives for pedagogical use as well as the difficult task of using them in the classroom. In this context, we seek to work in teacher training for insertion of History and Philosophy of Science (HPS) in classroom, and historical narratives become mediation elements to advance the dialogue with this specific audience. This initiative is in line with a recurring concern: one of the main challenges related to the didactic transposition of HFC would be the lack of teacher preparation. Historical contents and Nature of Science are still absent in classrooms. Insecurity and lack of knowledge by teachers are often mentioned as factors that contribute to this situation. It is important, therefore, that teachers (active and in training) take part in discussions concerning the inclusion of HPS in classroom. It is relevant that they know examples of historic-philosophical didactic proposals to address science and contents on science, develop skills to adapt them to their specific contexts and to develop their own proposals. It is believed that these issues are significant to undertake conscious initiatives to insert HPS in classrooms. It is considered that adapting educational proposals to particular educational contexts depends on understanding what these proposals indeed mean and how flexible they can be. In order to address these objectives, we elaborated an educational product, a didactic material focused on teacher training, which was used in an extension course at UFRN. The didactic material discusses the role of HPS in Education, Nature of Science and historiographical issues. It presents a series of dialogical activities on aspects of didactic transposition of HPS, especially those regarding historical narratives. A set of historicpedagogical texts on the History of Vacuum and Atmospheric Pressure is used as a mediation element in discussions. We address potential, possibilities and limitations historical narratives. To carry out the course, it was taken into account methodological concerns of so-called action research. There have been expected changes, modifications and effective actions in the own teacher training material in face of the experience of the researcher-lecturer in interactions with the participants of the course as well as in face of impressions reported by the participants. Developments in this direction have been incorporated into the teacher training material.
