Fontes primárias da história do vácuo e da pressão atmosférica na sala de aula: cartas e jornais históricos em articulação com o livro-texto do ensino médio

The use of the History and the Philosophy of Science (HPS) for the teaching of science and scientific subjects has been advocated in recent decades. It has been pointed out that the History of Science could make for a deeper learning of scientific concepts, since it would promote a contact with the problems which that knowledge has set out to solve. Furthermore, historical episodes would serve to put the discussions about the nature of scientific knowledge into context. With a view to explore those potentialities, the literature in the field has sought to identify the challenges and obstacles for the didactic transposition of subjects from the History of Science. Amongst many aspects, the deficiencies in the training of teachers, so that they can work with the insertion of HPS in the classroom have been highlighted. Another aspect that has been mentioned to be a challenge has to do with the didactic transposition of the Primary Sources, that is, of the original texts on the History of Science. The Primary Sources have significant potentialities: making a connection possible between scientists and concepts, showing the difficulties faced during scientific endeavors, perceiving the role of mistakes as obstacles to be surpassed, not as defeat, etc. On the other hand, there has been little exploration of these concepts in an educational context, due to their own peculiarities. The original texts are often hard to understand and their interpretation demands knowledge of the historical and scientific context in which they were written, as well as skills pertaining to the conduction of research in the field of the History of Science. With this scenario in mind, the research towards this Professional MSc degree starts from the challenge of elaborating and discussing proposals which could enable the didactical transposition of the Primary Sources. We have worked specifically with Primary Sources on the History of the Vacuum and of the Atmospheric Pressure, because of the insertion of these subjects in the Brazilian High School curriculum, in connection with the didactical textbooks. "Historic Journals" were made up from clippings of the original historical texts, as was a Didactical Unit, which takes the usual textbooks as a basis and contemplates using the Journals and the entire Primary Sources in High School. At last, we have elaborated and implemented a course designed for the preparation of teachers and for being an opportunity for the discussion of the feasibility of putting these kinds of proposal into practice

Dificuldades na construção de gráficos de funções

This study describes about graduation s students difficulties of to draw functions graph. Specifically, we intend to observe their abilities evolution, as well as their difficulties during Calculus I subject in engineering course. For that, we show them publications about the elaboration of graphs and its difficulties in obstacle terms and some researches witch contain this subject and that it was done during postgraduate studies in mathematical education. It shows by research methodology aspects related to French didatic s mathematic and some theories of cognitive psychology considering the high value between theoretical-methodological relation that was evidenced in both theoretical conceptions about ways to understand and teach mathematic. This methodology is based on didactic engineering purpose, that consist in preliminaries analysis, conception and didactic sequence analysis prior, trials by application followed analysis up and conclusion. We had also used pedagogicals actions and analysis of results achieved, to classify types of errors made by the 2005 s students during second semester, from conceptions related to the episthemologic and didactics obstacles

Da poesia ao poema: uma leitura do poema-Processo

Caractérisation du "Poema-Processo" au long de sa trajectoire entre les années 1967 et 1972, au regard d´une lecture visant son insertion dans le mouvement d´avant-guarde de la deuxième moitié du XX° siècle, au Brésil. On vérifie la façon dont le mouvement du "Poema-Processo" s´est formé, comme dédoublement de l´art concret, ainsi comme ses adéquations à la conjoncture de son apparition au Brésil, s´établissant une comparaison entre la pratique du poème et les propositions des manifestes lancés. L´analyse des poèmes sélectionnés démontre leur co-relation avec les travaux visuels initiés par les avant-guardes historiques, ainsi comme les réponses de la pratique poétique à la théorie developpée par les principaux représentants, Wlademir Dias-Pinto, Álvaro de Sá et Moacy Cirne. La production poétique et culturelle de Moacy Cirne est abordée en observant sa pratique sur trois points fondamentaux: la production poétique, la critique littéraire donnant de l´emphase à la culture locale et au texte du "Poema-Processo", et la recherche du language des bandes dessinées.

O evangelho por escrever: uma leitura do desassossego nos fragmentos de Bernardo Soares.

Cette recherche a pour but d approfondir des études qui mettent en lumière des particularités inhérentes au processus de l écriture fragmentaire. Notre intérêt pour ce thème provient de la poétique fragmentaire du Le livre de l intranquillité composé par Bernardo Soares, assistant de notaire et sémi-hétéronime de l écrivain Fernado Pessoa. Notre approche de ce genre textuel commencera par une méthodologie comparative qui nous donnera des notions pour que nous puissions établir quelques rapports de ressemblances et différences entre fragments, maximes, aphorismes et réflexions dont le corpus littéraire sera le journal intime de l intranquilité soarianne, ainsi que la fragmentation du simulacre d auteur au cours des années pendant lesquelles le Livre a été écrit. Le livre de l intranquillité lance des « pulvérisations » réflexives, lesquelles demeurent actuelles, étant donné que le processus de l écriture fragmentaire semble être toujours dans un mouvement constant et, donc, dans l ambiance du à venir. À partir de cela, nous avons passés pour quelques entraves pour essayer d établir une définition pour ce qui serait l écriture fragmentaire. Nous chercherons des points d intersection visant à établir des paradigmes pour obtenir des notions plus précises sur ce genre textuel, concernant les maximes, aphorismes et sentences refléxives.

Propaganda e discurso ideológico: um estudo dos slogans das campanhas de incentivo à leitura

Considérant que le Brésil est un pays considéré comme «non- lecteurs», nous avons essayé de trouver des solutions pour inverser cette situation d'exclusion sociale à travers des campagnes et des projets. Le slogan était le moyen de la propagande a proposé à cet effet. En étant un peu éclairante, il a été considéré qu'ils étaient peut-être inséré dans un contexte idéologique, en passant, qui faisait alors partie de l'objet d'études en question et, en conséquence, l'objectif était d'étudier comment, dans niveau discursif, les relations sociales de l'idéologie et du pouvoir dans ces dessins slogans verbaux et des campagnes publicitaires pour encourager la lecture. Nous avons utilisé comme instrument de collecte de données en 2007 slogans projets (sept) et l'intensification des campagnes de publicité dans les années 1995 à 2006, peu après la création de la descendance en 1992, où son fonctionnement a été analysé et discours idéologique, en cherchant à identifier les états effets de sens proposé. Nous avons utilisé pour soutenir la perspective de recherche d'analyse du discours de l'école française, affiliée à Pêcheux. Afin de sens les effets sens des tests a été fait une semi-ouverte aux enseignants qui traitent directement avec l'enseignement de la lecture de l'Institut de l'Enseignement Supérieur du Président-Kennedy, situé à Natal / RN. On été appliqués 100 questionnaires, parmi lesquels 60 d‟entre eux utilisés pour l‟analyse. La recherche a démontré par l'analyse, que la façon d'encourager les gens à lire se déplace à travers le modèle principal de la compréhension de la lecture à laquelle les slogans ont été utilisés, en les intégrant dans un discours dominant, qui ne contribue pas de manière significative à l'augmentation le nombre de lecteurs dans le pays. Grâce à l'analyse des slogans et la réception des sujets de recherche, nous nous rendons compte de la diversité et l'idéologie sont présents en elles, révélant tout le temps, la compréhension de la lecture comme une surface pratique, ne mettre en lumière certaines de ses fonctions Importantes au sein d‟um contexte éducatif plus large

O papel da leitura nas aulas de inglês: uma análise segundo a percepção dos professores do ensino médio de escolas públicas estaduais de Natal

This dissertation aims at investigating the teachers beliefs about the role of the reading ability in English at public state high schools in Natal and identifying the social value of the process of learning English for students of a foreign language. From the understanding of studies on reading, both in the field of Cognitive Psychology, as in Gibson & Levin (1975), as in the area of Psycholinguistics, as in Goodman (1970) and Del Re (2006), We researched the teachers perceptions about the skills and competencies that should permeate their educational practices, through their knowledge about theories of language acquisition as Cognitivism (Piaget, 1961) and Social Interactionism (Vygotsky, 1979) and the official documents (PCNEM, 1999; PCN+, 2002 ) that are the parameters for teaching a foreign language. We took into consideration other factors that influence the choice of the goals and the objectives to be worked out, such as: intensity of teachers workload, number of classes and students per class for each teacher, materials and technologies available, among other factors that will play an important role in the choice of the appropriate methodologies. To conduct a case study, two questionnaires were used in the construction of direct interviews with fourteen English teachers in twenty schools. According to data on the teachers beliefs we could find that for them the reading ability does not seem to have an special treatment in the teaching of a foreign language due to factors that undermine this process and therefore make teachers do not realize the real objectives of teaching English at public state high schools in Natal. As a consequence, the current process of education complicates the formation of autonomous learners capable of fighting for a social transformation

O trágico em lavoura arcaica

El escritor de São Paulo Raduan Nassar, lanza en 1975, su primera novela intitulado Lavoura arcaica. En su narrativa de estreno, el escritor nos trae la historia de un adolescente, André, que intenta destruir la plantación de su padre, Iohána. A través de sus sermones, el patriarca predicaba la moderación, la disciplina y la obediencia a las leyes impuestas por él, construyendo así, un mundo de ilusiones, donde el amor era una máscara para la hipocresía. En esta tensa relación, padre e hijo, representaciones místicas de Apolo y Dionisio, emprenden una contienda discursiva sobre la negación y la afirmación de la existencia. De ese modo, considerando la relación de lucha e integridad entre el impulso apolíneo y dionisiaco existentes en el romanticismo nassariano, la propuesta de este trabajo es presentar una lectura de lo trágico en Lavoura arcaica a partir de la perspectiva nietzscheana sobre el género trágico. Para eso, recorrimos al concepto desarrollado por Nietzsche en su obra, desde su primer libro O nascimento da tragédia (2007a), A visão dionisíaca do mundo (2005 a) y Ecce homo (2008 b).

Os Brutos: tradição literária e a memória cultural do Seridó

Partindo do princípio de que a força centralizadora do discurso do narrador sob o universo romanesco encontra-se regido por nuanças sócio-ideológicas que fazem parte do mundo psicológico do autor, procede-se uma leitura crítica de Os Brutos (1938), romance de estréia do escritor José Bezerra Gomes. O trabalho mencionado visa a tecer algumas considerações em torno do ponto de vista do narrador, enfocando a encenação do EU no cenário artístico-literário e sua interferência no modo de narração da citada obra. O procedimento metodológico adotado foi a pesquisa bibliográfica, e como aporte teórico recorreu-se à crítica especializada que trata da temática em questão. Ao final percebeu-se que o discurso do narrador possui um caráter ambivalente, o qual permite que o interlocutor presente não assuma uma perspectiva fixa diante do que narra

Processos cognitivos que operam na construção da referência: uma análise das produções textuais elaboradas na EaD - UFRN

Beneath the theoretical assumptions of Cognitive Linguistics contemporary, we analyze the cognitive processes underlying the construction of the reference in the text. To do so, we choose as corpus the written textual productions of undergraduates at the Department of Distance Education/UFRN provided in sections of responses of presential evaluation activities and activities in the Moodle virtual ambience. These activities and texts were produced in the discipline of Reading, Interpretation and Textual Production taught in the courses of Chemistry, Physics, Mathematics, Biology and Geography we monitor during the period of 2008.1 to 2010.1. Through the analysis of discursive productions, it was evident that the construction of the reference is made by means of the activation and manipulation of information acquired through our perceptual and social experiences. Thus, we confirm the cognitive assumption that the linguistic clues available in the texts of the activities serve as guides towards cognitive domains that activate the process of building reference

A tirinha cômica em questão: atividades de leitura no livro didático de língua portuguesa

You can see nowadays a more constant questioning about the validity and effectiveness of the practices of teaching reading currently introduced in elementary school. The intelligibilities generated from many voices, and built on the border between many consciences, it can contribute to understand and to some extent, alleviate skewed or outdated understandings about the teaching of reading and its goals in the school environment. By understanding the dynamics of these practices, which always need to be modified because of new social demands, we recognize the validity of working with the prospect of reading in its historical, social and dialogic dimension (Bakhtin, 1981, 2003). The Portuguese language textbook (LDP), in turn, being one of the fundamental bases of reading in school, makes a justified and necessary active production of knowledge about the theoretical and methodological conceptions that underlie the work with reading and on how that work is effectively routed. Our aim in this essay is precisely analyze reading activities in four Portuguese textbooks (Teacher s Manuals) for the 6th grade of elementary school, focusing on the proposed activities from a specific discursive genre, in this case, the comic strip. Through this research, we retrieve and list the goals that guide the development of reading activities in the LDP, and then verify a compliance or not of these objectives in directing the activities. Finally, we describe how the reading practices that involve the strip in the textbook can legitimize or reject the reading as an area of construction and circulation of meanings between socio-historically located subjects. We take account of studies on the nature and constitution of language (BAKHTIN, 1981, 2003, 2010; BAKHTIN/ VOLOSHINOV, 2006; SOUZA, 2002; GERALDI, 1996, 1997, 1999, 2006; ROJO, 2008a, 2008b, among others), as well especific studies about the activities in Portuguese textbooks (MARCUSCHI, 2010; BELMIRO, 2006; MENDONÇA, 2006, among others)

O hipertexto eletrônico de meio ambiente : estratégias de leitura e navegação

The incorporation of computing in class instigate the use of the Internet and websites as a content support in the teaching/leaning process. This kind of practice had challenged the students to read through eletronic hypertextual means. In that way, we re trying to undestand which strategies of reading and navigation the students of the second and third grade of highschool levels are using when reading electronic hypertexts from the www.ambientebrasil.com.br website. The research took place in the Escola Estadual Jerônimo Rosado in Mossoró RN. Our theoretical base was estructured on the digital Technology (electronic hypertext estructure and it s navigation modes), in applied linguistics (act of reading) and in cognition (interaction of the reader with the text and the use of reading strategies in the virtual computing enviroment). The applied methodology was the case analysis which was developed with the reunion of collected data through qualitative reseach questionaries, direct observations and video recording sessions. The research demonstrates that reader s ability in the act of navigating on virtual sites activates his/her reading strategies. Also shows how the semantic architecture of the hyperlinks can interfere directly over the strategies of reading and navigation in specific websites. Our research also intend to demonstrate that the student use his strategies of linear text reading when are not accustomed to use the reading through websites in a regular basis. The investigation concludes observing that the amount of hypertexts per pages and the inappropriate use of the multimedia elements were harmful to the reading fluency

Uma leitura dos exercícios dos excursos n Os Lusíadas

The Lusiads is an epic poem, written by Luís de Camões, about the adventure of Vasco da Gama s trip and the history of Portugal. It's based on traditionals epics from the Greek and Roman poets, Homero and Virgílio. Camões followes especially their structures. However, the poet insert modifications that divert his poem from parameters established by Aristóteles for the classic epic poems. These deviations are centered mainly on the narrative subject and in the point of view. We intend to show an analysis focused on digressions from The Lusiads, in which the author, himself or by tellers characters, narrates the story in order to make his complaints, reflections and exhortations. Besides, we present general aspects of Maneirismo predominant in these digressions how evidences of modernity of the poem; as one brief outlook about the poem's projection in time and around the world. These points are importants elements of consolidation of a universal permanence of The Lusiads. That's why they have had to read and to study by the centuries, according the vision of the epoch's spirit

Práticas de leitura e escrita na formação em ciências e tecnologia

The discussion about the need of improving the reading and the writing practices of professionals from the most different knowledge areas has caused, in Brazilian and foreign institutions of higher education, a movement of insertion of curricula components whose focus is the reading and the writing in academic formation. To contributing with the reflection about that discussion, this master s degree dissertation has as object of study the situated linguistic formation. Our general objective is to analyze a linguistic formation proposal to graduating students from the Bachelor s degree in Science and Technology (BCT) of the Federal University of Rio Grande do Norte (UFRN). To constructing that analysis, we have established four specific objectives: a) verifying if the ten brazilian Institutions of Higher Education which offer the BCT have curricula components of reading and writing directed to that formation; b) describing how these Bachelor s degree reading and writing curricula components are presented; c) examining differences and similarities which, in general, exist among curricula components related to reading and writing in each one of the researched institutions; d) revealing which categories delineate the linguistic formation developed in the BCT of the UFRN. In order to reaching our goals, this work has been based on the dialogical conception of the language (BAKHTIN [1952-1953] 2010), on the literacy studies (KLEIMAN [1995] 2008; TINOCO, 2008) and on the critical pedagogy (FREIRE, 1980; 2007). Methodologically, this qualitative research of ethnographic direction (ANDRÉ, 1995) is grounded in Applied Linguistics (PEREIRA; ROCA, 2009; PASCHOAL; CELANI (Orgs.), 1992). This research has the contribution of professors, scholars and monitors of the field of Reading and Writing Practices (PLE) and also graduating students from the UFRN BCT which had already studied PLE-I and/or PLE-II. The tools used for data collection/generation were: curricula components programs related to reading and writing in the BCT in the researched higher education institutions (IES), questionnaires, semi-structured interviews and profiles. The generated data allowed us to establish the following analysis categories: situationality (real situation, thematic contemporaneity and thematic focalization) and literacy projects (learning community and protagonism). The results achieved show that most IES which offer BCT worry about improving the reading and writing competences of their graduating students; however, there is still a lot to be done (increase of the number of class hours, contents and methodological aspects review, theoretical referential sophistication) so that the curricula components can be configured as a situated and significant linguistic formation. Finally, we make some suggestions for improving the work which has been made in the BCT of the UFRN, making then the mother tongue teaching in courses of the area of exact and technological sciences stronger

Modernismo e tradição da oralidade na poesia :uma leitura de Clã do jabuti, de Mário de Andrade, e Catimbó, de Ascenso Ferreira

Estudio sobre los libros Clã do jabuti, de Mário de Andrade, y Catimbó, de Ascenso Ferreira, publicados en el año de 1927. Dentro del contexto del Modernismo en los años de 1920, se evidencia la filiación de los poetas con las tendencias literarias modernista y regionalista. Eso se confirma por los elementos introducidos en sus poesías, en las referidas obras, que traen el sentido de brasilidade discutido en la época, específicamente en el momento post1924. Tales elementos se refieren a las marcas de la oralidad que fueron aprovechadas esteticamente en los referidos textos, en lo que toca a la representación que poseen en el ámbito de la tradición de la cultura popular brasileña. En ese sentido, fue establecida una relación entre la moderna literatura nacional y la tradición de la cultura popular. Los textos observados muestran la diversidad cultural del país por medio de tales marcas, distinguiéndose por el aspecto nacionalista de Mário de Andrade, en consonancia con el proyecto de nación idealizado, y por el aspecto nacionalista/regionalista de Ascenso Ferreira, saliendo al encuentro de elementos nacionales y regionales. Siendo así, Clã do jabuti es un repertorio de todo Brasil y representación de la cultura nacional, de acuerdo con la brasilidade propuesta a partir de 1924; y Catimbó es la cristalización poética, en tonos de una brasilidade más norteña, de las particularidades de la región

A leitura e o leitor presumido nas avaliações oficiais

Este estudio se refiere a una investigación a cerca de la concepción de la lectura que subyace en la Matriz de Referencia de la Prueba Brasil, y, mediante las análisis del modelo 2009, entender lo que el lector se supone que responder en las preguntas de esta prueba. El estudio tiene como objetivo satisfacer se presume lector general para responder a las preguntas de prueba de Brasil y el mapa de la concepción de la lectura que subyace en la matriz de referencia tal prueba. Los objetivos específicos apuntan a examinar los temas de Prueba Brasil, identificando qué descriptores se materializan en el mismo, que son los más recurrentes. El estudio tiene como fundamentos los estudios bakhtinianos a cerca de los diálogos del linguaje (Bakhtin, 2003, 2008; Volochínov/Bakhtin, 1993) y la concepción de la lectura defendida por Geraldi (2007), Larossa (2001) y DeCerteau (1994). La investigación és caracterizada como cualitativo-interpretativo, con enfoque socio-histórico, y se encuentra dentro del campo de la Lingüística Aplicada, que en las últimas décadas ha demostrado contribuciones para la enseñanza de lenguas y formación docente. Para hacer el análisis de las pruebas, inicialmente construido una tabla (Tabla 1), que contiene los seis macrotópicos Matrix lengua portuguesa en la que estábamos repartiendo los descriptores presentes en las cuestiones de prueba referenciada relacionándolos con sus temas. Tras analizar la cuestión, con el fin de identificar al presunto lector a responder a estas preguntas. Mediante análisis de la Matriz de Referencia de la Prueba Brasil, entendemos que ella está de acuerdo con los Parámetros Curriculares de la Lengua Portuguesa. Así, la concepción que subyace en la lectura es que la lectura es una actividad que depende del proceso individual, pero que és parte de un contexto social e involucra a habilidades relacionadas con la comprensión y producción de sentido. Mediante la observación de la prueba, afirmamos qué el lector con la capacidad de responder a las preguntas es lo que desarrolla actitudes favorables a cerda de la lectura. A saber: (i) reconocen ampliamente las palabras, (ii) identifican los objetivos y funciones de la lectura, en reconocimiento de la función de apoyo de género y el contexto del texto, (iii) predice el contenido de los textos a se lee a la luz de su apoyo, su género y su contexto; (iv) plantea hipótesis sobre el contenido del texto que se lee, (v) es capaz de buscar ideas textual e intertextual. Es decir, hace inferencias, aumentando la comprensión, la asociación de diversos elementos presentes en el texto y que son parte de sus propias experiências personales, (vi) construye la comprensión global del texto leído por la unificación de la información explícita e implícita, (vii) tiene la capacidad de evaluar la lectura de forma ética y afectiva, o de hacer extrapolaciones coerentes sin escapar de la temática del texto. Por último, podemos decir que las implicaciones pedagógicas de este trabajo para mi actividad profesional es de gran importancia, ya que desde la detección de lo que se requiere de los estudiantes y, en consecuencia, un nuevo enfoque para la enseñanza de la lengua materna como podemos reflexionar sobre eso y encontrar maneras de mejorar nuestro desempeño. Tanto nuestro entrenador como nuestros compañeros. Dejando a un nivel puramente descriptivo de los problemas de acción conjunta más eficaz, entendiendo que la enseñanza de lectura tiene un carácter complejo. En este sentido, tenemos que ser menos intuitivo y más reflexiva. Nos gustaría hacer hincapié en que tenemos la intención de socializar esta investigación con nuestros compañeros, ya que entendemos que es un material que puede contribuir a un nuevo aprendizaje para la práctica de los profesores que se inclinan. Además indicó que la principal contribución de este trabajo es nuestra mirada en el proceso de la lectura en el aula, la comprensión de que el estudiante de ofertas diarias con textos localizados, derechos de autor, histórico y representativo de las diferentes interacciones en el mundo. Por lo tanto, es el momento de ser gestado las prácticas de lectura hacia una educación más significativa
