Mecanismos sócio-genéticos da representação social de trabalho docente por grupos de licenciandos de física e de química da Universidade Federal do Rio Grande do Norte

This research aims to understand the social representations Teaching Work in groups of undergraduate students of Physics and Chemistry of the Federal University of Rio Grande do Norte. For this, the proposal was based on the three theoretical and methodological consensus Carvalho (2012) in the explanation of socio-genetic mechanisms constituents of dynamic consensus that has functionality to your organization. It Was used to achieve this goal, the theoretical-epistemological Serge Moscovici (1978, 2003), Jodelet (2011), Wagner (1998,( 2011) and Carvalho (2012). The corpus analyzed results from a qualitative and quantitative research, developed in three stages. The first two (2) questionnaires to fifty (50) of each undergraduate course, a questionnaire and another profile for collection of free associations concerning motes inductors "Give Lesson," "Student" and "Teacher". The second step in the procedure Multiple Classifications, Roazzi (1995), aimed for another thirty (30) undergraduate students for each course, as well as Document Analysis of Educational Projects Curriculum courses in Physics and Chemistry. The data analysis of the first stage focused on descriptive statistics and frequency and average order of the words associated with motes inductors. The results from the Multiple Classification Procedure submitted to multidimensional analysis (MSA multidimensional scalogram analysis) and SSA (Similarity Structure Analysis), were interpreted by the theoretical and methodological proposal of the three consensus, supported by analysis of the rhetorical nature of justifications classifications and categorizations of words, boosted in times of application of Procedure Multiple Classification. The data revealed that the groups surveyed were the same Social Representation with specific dynamic consensual. Thinking Teaching Work for these groups it is considered in three dimensions: the BE-DO-HAVE of teaching. In the group of Physics consensus was clear semantic, which expressed a dynamic in which the interpretations of "Teaching Work" peacefully coexist on perceptions of two concepts: An identity around the "BE" "Teacher" or "BE" "Educator" and the other, how they think about professional development. The type of group consensus Chemistry pointed to a consensual logic hierarchical order in which the gradual between the elements of BE-DO-HAVE attested conflicts and disagreements about the perceptual object "Teaching Work", around what value most, whether they are the attributes of personal or professional-technical dimension of teaching, in the course of professional development. The thesis to explain the mechanisms of socio-genetic Representation Social Teaching Work by theoretical and methodological proposal was confirmed

PROEJA FIC/Fundamental no IFRN-Campus Mossoró: das intenções declaradas ao funcionamento de um curso em espaço prisional

This research aims to analyze the FIC Course of Assistant Technician in Service Management and Quality, integrated to elementary education / EJA form developed by IFRN MO Campus between 2011 and 2013 in the form of a PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL. We seek to understand the adhesion between the national guidelines postulated for the Program, established in PPC and mediations with the process conceived in the run of the course. Guiding by the socio-critical approach and the dialogical paradigm, the theoretical-epistemological mark is especially buoyed by the theoretical contributions of Ciavatta (2005) , Rock (2011) , Haddad and Di Pierro (2000), Freire (2005), Marx (1982), Ramos (2005), Frigotto; Ciavatta; Ramos (2005), Moura (2012), and also on education in prisons by Onofre (2007, 2011), Bueno (2007), Julião (2011) and Foucault (2001). We assume that an action that enables professional qualification as FIC courses articulated to the EJA in the context of education in prisons have conceptual, methodological, political and pedagogical implications for it focuses challenges, weaknesses and opportunities on the same area of education., We have developed four techniques of data collection based on procedures and tools of qualitative research, such as document analysis, a student survey, the conduction of focus groups with teachers and administrators of the course and on-site observation. Mediated by the investigated context, results showed that the consolidation of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL goes beyond the intentions officially declared. It is inferred that after seven years of its creation, even though it keeps some potential, this program is not being satisfactorily developed and it shows weaknesses national and locally, it is set at low capillarity, it has a limited scope, and dissolved essential public commitments to the course development. The effectiveness of PROEJA FIC / AT ELEMENTARY SCHOOL LEVEL as part of an emancipatory inclusion social policy, according to official statement, entails approximating the legal logic with social logic, so as not only to propagate discourses and enforce worship to specific and successful experiences that reach only a minority, but to provide actual and necessary conditions to promote the breadth and social quality of the offered deals in this program format

O desenvolvimento profissional docente e a participação colegiado no Atheneu Norte-Riograndense

To investigate the relationship that exists among the educational participation of the school board and the teacher's professional development, starting from the analysis teachers of a public institution who teaches daily in the city of Natal. We focused the possible relationships between the teacher's action and their professional development, which includes the participation of the School board, considered by us as a collective space. To accomplish this research we used Interviews (KAUFMANN, 1996; SILVA, 2002) to analyze the nine participants, who are teachers' of the school board, and their oral speeches, considered as main references of our study. While trying to understand the reasons that led the teachers to choose her/his educational profession, we noticed the difficulty of recognition of the job of lecturing as a profession. This fact comes as an obstacle to the perspective of the teachers' professional development. In what he/she refers to the forms of the teachers' participation in the board and their meanings, we noticed in first place that the feeling of it belongs one of the decisive factors it can be considered actively for the teacher to announce of the actions colegiadas. This for them to want and they believe that that is the best road for if they develop better while professionals and consequently to improve the situation of the school. In second place we noticed that the school board represents, a place of articulation of the equality among all the ones that form the school community. So, we tried to understand how they happened to the collective actions in the school, how the teachers presented them in spite of what they know, how a collective action should be presented in the elements of fragility of that process that inhibit the development of the overall action. Finally, we questioned the elements that would contribute to the educational professional development; we noticed that the teachers present the competence, the ethics and professional valorization, as factors that contributed at the present time to their educational professional development

A aprendizagem na convivência:o estágio curricular em enfermagem

This is an analytic research of a qualitative nature whose purpose is to examine the learning process involving students of the Nursing Program of the Universidade Federal do Rio Grande do Norte UFRN who are attending the Supervised Clerkship in Nursing (SCN) in Family Health Strategy (FHS), based on learning through daily living. In order to do this, a historical overview of this academic activity in the teaching of nursing was presented, and the importance of FHS as the scene where professional health education takes place was discussed. For the empirical investigation, ten eighth-semester students involved in clerkship activities at family health units in the Western Sanitary District of Natal, Rio Grande do Norte, were interviewed. The theoretical approach relied, as epistemological presupposition, on the ideas of educator Humberto Maturana who showed that learning, both in nature and among human beings, takes place within dialogic living relationships wherein acceptance of the other, affectivity (love) and dialoguing are essential stimuli to learning. Students discourses gradually became part of the analytic categories that had been established beforehand. There has been verified that the students went through meaningful learning encouraged by all who shared the living environment, that is: nurse/instructor, teacher/supervisor, family health staff, and the community. Several feelings were involved in the process, such as joy, satisfaction, self-reliance, affectivity and, in the opposite direction, sadness, indignation, a feeling of impotence, and fear. The learning of interpersonal relationship was describe as the most relevant of the academic experiences and, therefore, thus emphasizing the relevance of affectivity to the learning process as Maturana points out. It is suggested that the teaching of nursing keep on giving priority to family health units as the Basic Care educational scene, with attention to the importance of placing the students in welcoming environments, in such a way as to encourage learning

A violência no contexto de um serviço de urgência: análise do processo de cuidar na visão das vítimas e profissionais de saúde em Natal/RN

Exploratory descriptive study, with a quantitative approach and prospective data, performed in Pronto Socorro Clóvis Sarinho (PSCS), in Natal/RN, aiming to analyze care given by the nursing and medical staff to victims of violence attended to in an emergency hospital in Natal/RN; to identify care given by the nursing and medical staff as viewed by the victims; to compare data observed during the process of care with the victim s view on the care given by the nursing and medical staff; to identify the existing knowledge on violence and the process of caring for victims and its relation with prejudice; to identify obstacles and perspectives for prevention during the process of caring for victims in the emergency services. The population consisted of 97 physicians, 16 nurses, 75 nursing technicians and assistants and 365 victims of violence, with data collected from April to May 2009. Out of 188 professionals, 52.1% are female; 32% were aged 41 to 50; 99.5% had given care to a victim of violence; 90.4% reported to have given care to patients under custody; among these, 17.3% felt prejudice; 55.3% stated they don t provide different care for assaulted victims and assailants, however 44.7% stated they do; 86.7% feel their workplace is unsafe; 61.7% denied the existence of any obstacle and 38.3% reported the existence of obstacles; among these, 26.1% referred to inadequate facilities; 37.8% believe reinforcing security and professional training are the main solutions. Among the 365 researched violence victims, 82.2% were assaulted; male (69.6%); aged 18 to 24 (24.9%); hailing from the Greater Natal area (89.9%); on 19.7% the event happened on Saturday; during the night (48.8%); victim of physical assault (61.4%); produced by body force (27.7%); 24.4% were injured in the head and neck. 57% had used some drug, among which alcohol was predominant (75.5%). On 621 observations performed during the victim care process, when compared to the report of assaulted victims, there was a statistical difference, at 5% significance level, regarding reception, resistance from the professionals, questioning about the violent event, providing of guidance, interaction with the patient and the understanding of receiving proper care, and care resolution. In comparisons involving the observed and the assailant victims reports, there was a statistical difference regarding the resence of resistance from the professionals, performance of necessary procedures and the nteraction with the patient and the understanding of receiving proper care and 58.1% reported the nursing team was the one that provided the best care. We conclude that professionals had lready given care to assailant patients, acknowledge the importance of knowing how the vent took place and acquired this preparation during their practice. The most often referred bstacles that hinder assistance were: inadequate facilities, material deficit and lack of rofessional preparation. As solutions for these problems, they cited the reinforcement of ecurity and professional training

Mapeamento robótico 2,5-D com representação em grade de ocupação-elevação

This work introduces a new method for environment mapping with three-dimensional information from visual information for robotic accurate navigation. Many approaches of 3D mapping using occupancy grid typically requires high computacional effort to both build and store the map. We introduce an 2.5-D occupancy-elevation grid mapping, which is a discrete mapping approach, where each cell stores the occupancy probability, the height of the terrain at current place in the environment and the variance of this height. This 2.5-dimensional representation allows that a mobile robot to know whether a place in the environment is occupied by an obstacle and the height of this obstacle, thus, it can decide if is possible to traverse the obstacle. Sensorial informations necessary to construct the map is provided by a stereo vision system, which has been modeled with a robust probabilistic approach, considering the noise present in the stereo processing. The resulting maps favors the execution of tasks like decision making in the autonomous navigation, exploration, localization and path planning. Experiments carried out with a real mobile robots demonstrates that this proposed approach yields useful maps for robot autonomous navigation

Estudo dos óxidos A2B2O7 e ABO3 a base de terras raras, para aplicações térmicas e catalíticas a altas temperaturas

Rare earth elements have recently been involved in a range of advanced technologies like microelectronics, membranes for catalytic conversion and applications in gas sensors. In the family of rare earth elements like cerium can play a key role in such industrial applications. However, the high cost of these materials and the control and efficiencies associated processes required for its use in advanced technologies, are a permanent obstacle to its industrial development. In present study was proposed the creation of phases based on rare earth elements that can be used because of its thermal behavior, ionic conduction and catalytic properties. This way were studied two types of structure (ABO3 and A2B2O7), the basis of rare earths, observing their transport properties of ionic and electronic, as well as their catalytic applications in the treatment of methane. For the process of obtaining the first structure, a new synthesis method based on the use of EDTA citrate mixture was used to develop a precursor, which undergone heat treatment at 950 ° C resulted in the development of submicron phase BaCeO3 powders. The catalytic activity of perovskite begins at 450 ° C to achieve complete conversion at 675 ° C, where at this temperature, the catalytic efficiency of the phase is maximum. The evolution of conductivity with temperature for the perovskite phase revealed a series of electrical changes strongly correlated with structural transitions known in the literature. Finally, we can establish a real correlation between the high catalytic activity observed around the temperature of 650 ° C and increasing the oxygen ionic conductivity. For the second structure, showed clearly that it is possible, through chemical processes optimized to separate the rare earth elements and synthesize a pyrochlore phase TR2Ce2O7 particular formula. This "extracted phase" can be obtained directly at low cost, based on complex systems made of natural minerals and tailings, such as monazite. Moreover, this method is applied to matters of "no cost", which is the case of waste, making a preparation method of phases useful for high technology applications

Aprendendo e ensinando o sistema de numeração decimal: uma contribuição à prática pedagógica do professor

The central question of the present study is to identify the epistemological knowledge that the teachers-trainees possess regarding the characteristics (properties) of the decimal numbering system; its purpose is to offer a contribution to the pedagogic practice of the teachers who work within the Basic Literacy Cycle, in terms of what concerns both the acquisition of contents and the development of the knowledge that helps them in the elaboration of adequate strategies to working with the Decimal Numbering System in the classroom. The study is based on the constructivist sociointeractionist approach to teaching Mathematics and it constitutes, in itself, a methodological intervention with the teachers-trainees engaged in the Professional Qualification Program in Basic Education of the Federal University of Rio Grande do Norte. The foundations of the study were found in investigations of researchers who had carried out studies on the construction of numerical writing, showing, for instance, that the construction process of ideas and procedures involved in groupings and changes to base 10 take a lot longer to be accomplished than one can imagine. A set of activities was then elaborated which could not only contribute to the acquisition of contents but that could also make the teachers-trainees reflect upon their teaching practices in the classroom so that in this way they will be able to elaborate more consistent didactic approaches, taking into consideration the previous knowledge of the students and also some obstacles that often appear along the way. Even when teachers have access to the most appropriate dicactic resources, the lack of knowledge of the content and of the real meaning of that content make the Decimal Numbering System, a subject of fundamental importance, be taught most times in a mechanical way. The analisys of the discussions and behaviours of the teachers-trainees during the activities reavealed that they made them reflect upon their current practices in the classroom and that, as a whole, the aims of each of the activities carried out with the teachers-trainers were reached

A difícil aceitação dos números negativos: um estudo da teoria dos números de Peter Barlow (1776-1862)

The present study seeks to present a historico-epistemological analysis of the development of the mathematical concept of negative number. In order to do so, we analyzed the different forms and conditions of the construction of mathematical knowledge in different mathematical communities and, thus, identified the characteristics in the establishment of this concept. By understanding the historically constructed barriers, especially, the ones having ontologicas significant, that made the concept of negative number incompatible with that of natural number, thereby hindering the development of the concept of negative, we were able to sketch the reasons for the rejection of negative numbers by the English author Peter Barlow (1776 -1862) in his An Elementary Investigation of the Theory of Numbers, published in 1811. We also show the continuity of his difficulties with the treatment of negative numbers in the middle of the nineteenth century

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

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

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

O medo da morte e os temores infundados: uma investigação acerca da natureza da alma em Lucrécio.

Lucrèce, penseur latin du siècle I, avant J.C., écrire que le peur de la mort imputé par la religion et la superstition, nourrit le souhait à la richesse, l'ambition du pouvoir et les actes insensés, dont les conséquences se reflètent dans les maladies de l'âme. La terreur qui s'installe chez l'homme, à l'être confronté au décès, est aussi un obstacle à la liberté et à la vie équilibrée. Les craintes sans fondement seulement seraient surmonter, avec la compréhension de la nature et du mouvement de l'âme, en percevant leur génération, corporéité et finitude. Pour cela, la compréhension des atomes et du vide, les éléments primordiaux de la nature se basent tout la connaissance de l'âme. L'objectif de ce travail est enquêter la nature de l'âme dans Lucrèce, en présentant une réflexion sur les craintes sans fondement et la peur de la mort, comme une manière de percevoir le mouvement de la vie elle-même, et de que manière sa philosophie affronte à la crainte de la mort.

Tí estin Anámnesis? uma análise da anámnesis no mênon de Platão

Cette thèse a pour objectif principal examiner comment les Mênon, Platon listes l'anámnesis avec les autres théories qui sont abordés dans ce dialogue et, par conséquent, essayer de comprendre ce que c'est. Cette recherche vise dans un premier temps situées dans d'autres dialogues de Platon la survenance du terme anamnésis à veifique les points qui relient ces oeuvres à clarifier la compréhension d'un plus approprié dans le Mênon. Jetez-y aussi, quels sont les éléments de la platonicienne théorie de la connaissance sera reliant le dialogue afin de prouver que le Mênon, qui est la question centrale areté, garde un conflit dans la sophistique et la philosophie. Ce choc entre ce qui se passe papapep indirectement par l'intermédiaire de son Mênon enseigné, et Socrates qui conteste la thèse de l'éthique et le relativisme épistémologique. Nous voyons aussi, de quelle manière le dialogue est donnée de prendre une voie d'accès au savoir qui est configuré comme sûrs, à savoir anámnésis. L'interrogatoire de Mênon depuis le début dans les appels d'enquêter éristique cet intérêt, que lorsqu'ils sont confrontés à des intérêts les amènerait à l'état aporétique initial et qui est progressivement remplacé par l'aporie fondamental de connaissance, ce n'est point pour aporie la compréhension de anámnesis. En prenant la dialectique comme méthode d'enquête dans le dialogue, il est nécessaire de la part de Socrates et Mênon, de quitter le didaskein et en profiter pour mathésis que la construction des connaissances. Il ouvre de manière un des principaux enjeux dans ce travail examine si le anámnesis permettre l'accès aux moyens et si elle a un statut similaire à mnéme. À un moment où Socrate explique dans le dialogue qui est le anámnesis par monstration monstration fait avec esclave de Mênon il est l'utilisation d'éléments mythiques que, selon notre analyse, permettre à comprendre le sens de dialogue les connaissances qui montre l'opportunité d'apprendre, qui est la anámnesis
