The accomplished researches in the education field focus on the importance of the accomplishment of actions involved in the analysis of the needs to graduate teachers as a way to adequate to socialcultural changing that require more and more a creative activity to prepare teachers in their graduation perspective. The worry with a fail at school linked to public school students lead us to make this thesis which goals are: investigate the needs of the graduation of teachers at public Elementary Schools concerning to the subjacent knowledge to the development of a pedagogic practice of alphabetizing with literacy and (re)create, with some teachers as active participants in the researches, knowledge regarding the process of alphabetization with literacy , based on the graduation of teachers. The study was accomplished in a municipal Elementary School in the Ceará-Mirim city, located in the state of Rio Grande do Norte, which offers both I and II levels of the Elementary School, 7 teachers and the principal of the school were subjects of our researches. The starting point was the needs of the graduation as subject phenomena, socially created and that allow people to be aware of the goals of a graduation. The investigative broach is qualitative, whose fundamental purpose is the understanding of the meanings, symbols, values and intentions of the mankind actions, as regards to other humanbeing and the contexts in which they interact. Within this context, we chose the investigation-action for we consider this kind of research a place for investigation and professional graduation, in which teachers and the researcher herself assume responsibility of problematizing, build the needs of graduation and think about their practices. As proceedings to create and analyze data, we developed participant observations during the activities in classroom; semi-structured interviews (individual and in groups) with teachers and the principal; analysis of documents and meetings at school for reflexive studies that enabled us to gather data in a pyramidal panoramic view and analyze the contents. The research revealed that the analysis of necessities to graduate teachers is a resource able to contribute to the planning of projects of keeping on graduating more properly, and thus create a critical and reflexive identity for teachers. This way, it was possible the graduation necessities could be revealed and also the knowledge of teachers as regards to alphabetization inserted in a perspective of literacy. Nowadays, conceptualized needs upon difficulties of teachers, there is a tendency to translate them into theorization of problems, without application to these knowledge of teachers, as well as their wishes for changing, especially when those needs are built to analyze and consider concrete practices. Therefore, the graduation experiences have enabled the abandon of a mechanical broach for teaching reading and writing. It has also lead teachers to assume a posture of providing their students the understanding about the reading and writing processes and their functions as social instruments. The graduation theme contents allowed the knowledge to conceive reading and writing in new perspectives, according to their social functions, so that they can improve the education with literacy quality. This theoretical construction has enabled us to understand and consider the necessities of the graduation as progressive process, and has given us the possibility of re-think our own learning processes at the university and review the pedagogical practices of public school teachers. Our conclusion is that once teachers consider their own graduation needs, it contributes to change their concepts and practices in education and literacy, even though there used to be many difficulties in their graduation and organization of the pedagogical work

This study aims to investigate the contribution of supervised training for training reflective of the students in the service of pedagogy course of the Vocational Training Program for Basic Education - PROFORMAÇÃO Universidade Estadual do Rio Grande do Norte / Campus Avançado Professor João Ismar de Moura - CAJIM Patu City / RN. Based on studies of Schon (2000), Alarcão (2003), Pimenta (1994, 2000), Tardif (2002) Ibiapina (2008) among others have adopted a theoretical framework which have been focusing on studies concerning the formation of the reflective teacher, in perspective also contribute to the professionalization of teachers. The study falls within the qualitative approach of educational research and the methodology chosen has characteristics of a collaborative research. In the process, we used the following instruments: individual and group interview, sitting reflective observation, videoformação, material prescribed personal documents. The relevance of this research is to highlight the contribution of reflexive perspective in the teaching profession for: knowledge of teachers, teacher professional development, relationship between theory and practice, collective work, school and university as a place of training. These findings indicate that: a) the stage for advanced teacher becomes a teacher action research, seeking to (re) signification practices, b) the stage still presents itself as an activity limited to the applicability of the theories, hence the need for dialogic relations between theory and practice in education, requiring their redefinition c) despite experiencing an in-service training, the students still need information to enable them to link theory to practice, but understand its importance, d) a collaborative discussion can be a strategy that encouraged and implemented, is likely to be an alternative to the consolidation of training reflective e) It is important to the collective action of teachers in the school and the university as an opportunity for development of the reflective process f) the students-teachers still do not understand what is reflection and not experiencing it, but realizes the need to change the thinking and way of acting, g) there are conflicts between the teacher's knowledge of the students, teachers and the actions constituting the real, creating contradictions between saying and doing training

This paper discusses the process of training social workers in the environment of University Hospitals- UH s. These hospitals provide space for professional education aiming to achieve a critical and purposeful professional performance. As environments for training, producing knowledge and providing essential services to the public, these hospitals require all members of the healthcare team to have a continued education. Understanding that training has to be a priority and conceived as constant pursuit for update through the interaction of Teaching, Researching and EPO ( Education and Public Outreach). These dimensions provide approximations and domain of theoretical and methodological, giving special importance to understanding the social reality, a sine qua non condition to the work of the Social Service professional. The main goal of the research was to comprehend how the continuous professional education of the social worker occurs and it s relation with the articulations involving Teaching, Researching and EPO, as significant elements for the job of the social workers in the Hospital Universitário Ana Bezerra and Hospital Universitário Onofre Lopes/UFRN. The research was conducted through a literature review, documentary and field inquiries with semistructured interviews including the group of 09 (nine) social workers from the aforementioned hospitals, taking as a reference the quantitative and qualitative approach to analyze mediations that stand between the subject and the social context. The results indicate that social workers in these university hospitals have their insertion beyond the care provided to patients in performance in the areas of education through preceptorship to undergraduate students and social work residents in and extension projects with low insertion in area of research. We note that there is a recognition of the importance of a continuous education, indicating that the qualification of social worker is essential in transforming their daily professional practice to better monitor, critically explain the peculiarities of public health in its everyday showing of how unequally access is provided to the users of the public health system

This collaborative research is a qualitative approach, from historical and cultural perspective, made about a teacher of third grade of basic education in the area of history, in the municipality of Caicó / RN. It has as objective to investigate, in a collaborative action, if the design process of teaching and learning the discipline of history based on the relationship before / after allows the development of critical reflective thinking of the teacher in school practices. The theoretical and methodological approaches are supported in the postulates of Vygotsky (1998), Rubinstein (1973) and Linblinskaia (1979), among others, whose understanding has led us to reflect if the teacher develops the reflective critical-thinking in history discipline classes. The complexity of the study led us to an analysis exercise, using different methodological procedures, such as: bibliographic review of the literature, considering also the literature of the history area, interviews, observation in the classroom, video recordings and reflective sessions, enabling clarify the construction and reconstruction of thought that the teacher had been developing during the process of teaching and learning. The test results point to a dichotomy between theory and practice, and also to a certain fragility in the position of professor in teaching and learning the discipline of history, at the third grade of basic education. The teacher recognizes that she requires a theoretical deepening with more intensity, as a process of continuous training to improve the practice of teaching in history school, though, stating in her speech that her teaching practice is based on critical reflection. However, she presents serious limitations in classroom practices. We conclude that, although she has shown willing to work on a critical perspective of reality, showed also poor change at school practices, starting to reflect about her own actions, pointing her limits and the changes needed that didn t become reality yet. It s necessary a formative process for her. The study therefore showed that even with the sessions and reflective of deepening theoretical studies, the teacher does not change its profile, while maintaining its traditional vision in any pedagogical action. This research recommends the formation of school groups for further studies and discussion on the practices of education in history area from a reflective-critical thought perspective as a mean of personal and professional development

This work is based on a reflection about my personal and professional background as a teacher and a pedagogical supervisor in two public schools in the municipality of Natal, RN, and how relevant this background is to the development of a proposal of continued formation within the scope of the school, in which a diversity of actionreflection strategies are present. In such contexts, I have identified several of my personality traits as being likely advantages or disadvantages that may contribute or not to the coming up of misunderstanding situations. The self-research experience and the identification of new dimensions of self-evaluation, self-observation and attention serve as a basis to think about the importance of experiencing the understanding within the ambit of the school. The reflections about my actions and those of the teachers bring up the hypothesis that the misunderstandings in the teaching-learning process and in the affective relations are the result of a fragmented, naive and egotistic way of thinking. Thus, they don t contribute to an experience of mutual understanding. That is why there must be an investment on new strategies of self-research and dialogue within the scope of pedagogical meetings that may come to help all educators with the analysis, identification and solving of their own problems as well as the other s. Under this perspective, the question that guides this study assumes the presupposition that the educator can invest in a qualified and meaningful pedagogical formation, either one s own and others , if one has a critical-reflexive overview about oneself and the school s pedagogical process. This research aims to explore, discuss and encourage new reflections about the act of researching in the pedagogical supervisor s role, questioning about the possibility of this action to generate contributions to the process of one s own and other s pedagogical formation within the scope of the school, in a conscientiological perspective, in which the manifestation of the thosenes of the educators are valorized. We approach Paulo Freire (1921-1997), as we see the dialogue as very important to the development of this research work, as well as an encouragement to the consciential dialogue. The empirical research took place from June 4, 2004 to November 11, 2004, with 8 pedagogical meetings and with the participation of 2 pedagogical supervisors and 8 teachers. The application of this new methodology within the scope of pedagogical meetings brought considerable contributions to the interpretation of the elements of the educators thosenes, classified according to the following: uncritical, naïve and critical thoughts; sentiments of assistential or non-assistential affectivity; and actions that may or not make the experience of mutual understanding possible. The action of the pedagogical supervisor and one s contributions to the understanding brought up reflections about new ways of investing in the process of continued formation within the scope of the school

This paper aims to investigate the formative needs of Elementary School Arts teachers at municipal public schools in Natal, Rio Grande do Norte, working in the initial grades. The research was developed using the qualitative approach and the investigation can be classified as an action research-inspired collaborative, distinguished by mutual collaboration among all participants, as well as a reflection upon their practice. Conducted with four Arts teachers of Municipal Education de Natal/RN, this work triggered a (re)thinking of teaching practice in Arts, discussing the teachers' formation and encouraging a group reflection about their academic and professional path. Their motivation towards teaching was also discussed, as well as the way their progress as Arts teachers and the contributions and limits of college education, also including experiential knowledge as a possibility of formation. The main formative needs suggested by the research were knowledge on child development and child learning, and the need of an Arts curriculum proposal for the initial grades of Elementary School. From those data, a reflexive context was built with the participant teachers to give a new meaning to Arts teaching practice in the first years of Elementary School. Finally, it was shown that the Arts teacher formation must be broad and involve not only specific knowledge on Arts, but also knowledge about childhood. It was also clearly shown that a curriculum review in education undergraduate courses must be considered, besides the offering of a continual formation to teachers already giving classes. Concerning the Arts curriculum proposal, it should be done based on a work joining officials of Municipal Education, research and formation institutions and teachers working in the first years of Elementary School. Finally, the work highlights the Arts are essential in all levels of Elementary School, since its first years, and it must be taught and learnt since childhood

The present study describes theoretical practical relationships between development and application of activities in Mathematics education. It s proposed a methodological approach to Mathematics in the first grade of Ensino Médio, supported by an experiment involving Irrational Numbers education by using constructive activities, applied obeying an educational sequence. Constructivism is used as an important theoretical reference in teaching learning process of Mathematics. The methodological intervention was done with two classes of students of the first grade of Ensino Médio, in two public schools, a state one and a federal one, located on the city of Natal, Rio Grande do Norte. The development, application and testing of the activities used on this experiment led us to think more profoundly about the value of constructivism ideas and understand that the use of activities that obey an educational sequence favors the learning. It s also discussed the research results, commented on a way to contribute to the advances of the proposal and it s more constant use. The participation and testing of the students were analyzed and judged using Skemp s Instrumental Understanding and Relational Understanding concepts. The results of the research were considered good, so we believe this methodological intervention can be used more frequently in the classes of Ensino Médio and also be applied to teachers in courses of initial education and continuous formation

This dissertation aims to analyze the relevant knowledge in countryside History teachers practice in high school and understand how these teachers themselves construct school knowledge in History, from the mobilization of different knowledge that make up teaching practice. Tree teachers from State Jacumauma High School and the researcher himself worked together in order to carry out this survey. The main theoretical-methodological elements of this research are based on assumptions of a qualitative research in cooperation. This approach was used to make possible to construct knowledge between teachers and researcher considering a less oppressive relationship as well as to help a continuous school upbringing of the individuals what can make them to understand the professional practice as an aspect in which one can exercise autonomy and criticism. The empirical research procedures were oral individual interviews, reflexive sessions and cooperative observations. Individuals speeches have presented, in some moments, teachers concerns about the educational fragmented system in which there are few opportunities to dialogic interactions among educationalists making still more difficult the dialog between school and reality surrounds it. Their assertions pointed out that relevant knowledge can be identified during the daily educational work and that they find proper reasons from the aim that each knowledge exerts in relation to the construction of professional practice. Classroom connections points out to more intense interactions between teachers and students, by recognizing affection as an important tool in order to make the interactions not so authoritarian at all. Regarding the countryside teachers understanding, the school knowledge in History is produced by sharing concerns and senses assigned by the individuals who are involved in the teaching-learning process. The referential science knowledge pervade History teaching, however they take another meaning according to specific features of the school environment. The intense and complex dynamic of the educational context makes that historical knowledge acquires specific characteristics that are constantly changing. As they change, there are some marks of elaborations and re-elaborations not only the new but also the traditional

This research aimed to know and analyze the pedagogical practices that have been developed in the teaching and learning of students with Intellectual Disability (DI), enrolled at common class of elementary school I. The study was conducted in a public school at Natal/RN, involving two students with DI, a multipurpose teacher, a teaching assistant, a teacher of arts and educational coordinator. As for methodological choice, we chose to develop a qualitative study, undertaking a case study. As tools for the construction of the data we use: semi-structured interviews, participant observation, field diary and document analysis. Data analysis reveals that the institution in which the research was undertaken gradually implementing changes in order to develop an inclusive practice, consistent with its assumptions. Regarding the practices developed in the teaching and learning of students with intellectual disabilities, it was possible to realize the fulfillment of certain adjustments in relation to the objectives, activities and some content, involving the use of resources and varied strategies. With regard to educational activities, we found that these had different levels of complexity, covering both basic goals as more complex objectives. From the observations, we realize that the Assistant Professor of mediations during varied activities as challenging tool in intellectual processes. We note, too, a dynamic classroom in which disabled students were under the guidance of Assistant Professor, and other students with all-round teacher who had a fairly traditional teaching methodology. It created thus an isolation situation, since there was no proposition practices to be developed with all students, and interaction among classmates, generally quite restricted. Although were highlighted developments in the social and academic learning of the surveyed students, the teachers said they did not feel prepared to work freight inclusion. The study reveals the need for teachers reviewing some actions undertaken, in order to develop more democratic pedagogical practices of education, stimulating the interactions between students, by proposing challenging activities that promote the formation and concepts. In addition, it points to the need of the education system invest and encourage the qualification of teachers with regard to education in an inclusive perspective, through actions that promote lifelong learning. It needs to be developed on the teacher a reflective attitude, resulting in a view that due diligence must be entered in practice inherent in teaching in order to use to enhance their educational experience.

Continuous Synthesis by Solution Combustion was employed in this work aiming to obtain tin dioxide nanostructured. Basically, a precursor solution is prepared and then be atomized and sprayed into the flame, where its combustion occurs, leading to the formation of particles. This is a recent technique that shows an enormous potential in oxides deposition, mainly by the low cost of equipment and precursors employed. The tin dioxide (SnO2) nanostructured has been widely used in various applications, especially as gas sensors and varistors. In the case of sensors based on semiconducting ceramics, where surface reactions are responsible for the detection of gases, the importance of surface area and particle size is even greater. The preference for a nanostructured material is based on its significant increase in surface area compared to conventional microcrystalline powders and small particle size, which may benefit certain properties such as high electrical conductivity, high thermal stability, mechanical and chemical. In this work, were employed as precursor solution tin chloride dehydrate diluted in anhydrous ethyl alcohol. Were utilized molar ratio chloride/solvent of 0,75 with the purpose of investigate its influence in the microstructure of produced powder. The solution precursor flux was 3 mL/min. Analysis with X-ray diffraction appointed that a solution precursor with molar ratio chloride/solvent of 0,75 leads to crystalline powder with single phase and all peaks are attributed to phase SnO2. Parameters as distance from the flame with atomizer distance from the capture system with the pilot, molar ratio and solution flux doesn t affect the presence of tin dioxide in the produced powder. In the characterization of the obtained powder techniques were used as thermogravimetric (TGA) and thermodiferential analysis (DTA), particle size by laser diffraction (GDL), crystallographic analysis by X-ray diffraction (XRD), morphology by scanning electron microscopy (SEM), transmission electron microscopy (TEM), specific surface area (BET) and electrical conductivity analysis. The techniques used revealed that the SnO2 exhibits behavior of a semiconductor material, and a potentially promising material for application as varistor and sensor systems for gas

In recent decades, debates have intensified about (auto) biographical narratives as devices of socio-educational practices, aligned to the educational setting of the XXI century which have stimulated a new educational perspective woven with epistemological and methodological training throughout life. Towards that scenario, the continued training in Judicial School has occupied important space for constitutional effectiveness and, on the other hand, has grown the demands of expanding knowledge and enhancing training practices, in turn, judicial practices. The aim is to analyze the reflective Group through "Professional Training biographical Workshop" with Bailiffs such as socio-educational practices in socio Judicial School, in the city of Natal /RN. It has highlighted the questions that guided this study: 1. What paths of experiences and knowledge shared by the Law Officials, Federal Appraisers in "Professional Training biographical Workshop" as reflective Group? 2. How is organized the reflective Group as practice in socio-professional training setting? 3. What contributions narratives of themselves bring to the bailiff in reflective Group on Judicial School? The theoretical assumptions are supported in the lifelong training in methodological and epistemological dimension of (auto) biographical knowledge (JOSSO, 2008, 2010, 2012; PINEAU, 2005, 2006; DOMINICÉ, 2010; DELORY-MOMBERGER, 2006, 2008; FREIRE, 1987, 1996, 2001; PASSEGGI, 2008; 2010; 2011; 2012). In 2009, 09 (nine) civil servants in post of Federal Appraiser Justice Official, law graduates participated in this research through eight (08) "Biographical Workshops of Professional Training", consisting of biographical practices and scenarios, enabling oral and written narratives about a memory that has meaning, relationship and tessituras between files, facts and feelings that reveal the perception of self and other, as well as mobilize and weave the training process. The experiences of speaking, writing and reading were constituted of spaces that facilitating the reconstruction of the trajectory of training and career awareness-making, helping to re-signify labor relations and lead to their own professional design. From this study, the reflective properties of groups have emerged, consisting of Reflexivity, Experience, Historicity, Reversibility, dialog and formability processes, with paths to social and educational practices in which professionals identify the meaning and significance of self and of the profession that are exercising. The expectation is to continue with the spirit of research to emerge from the participants responses to training practices in Judicial School, aligned with the new knowledge of understanding the human being, not only an object of his work, but also a social subject, co-participant in the process of re-signifying life and work in a permanent way.
