Esta dissertação de mestrado tem como objetivo contribuir com a construção de um currículo para o ensino médio, elaborado com a participação dos professores, que tem como princípio a abordagem multirreferencial. Esta abordagem permite uma leitura plural para compreender os processos educacionais, ao mesmo tempo em que possibilita analisar os objetos e sujeitos da pesquisa a partir de diferentes olhares e perspectivas. A pesquisa foi realizada em um desenho diferenciado, já que a autora atua, contemporaneamente, como pesquisadora e, com sua equipe de trabalho, como sujeito pesquisado. A autora optou pela metodologia de historia de vida por considerar que as histórias de vida de educadores que cotidianamente vivenciam a atividade educativa se constituem em ricos e singulares processos. Nessas condições, a coleta de dados se deu por meio de relatos autobiográficos dos professores, os quais foram lidos, analisados e discutidos coletivamente pelos sujeitos pesquisados. As discussões e reflexões comprovaram a relevância de envolver, na formulação de um currículo, os sujeitos que constituem os processos educativos, ao mesmo tempo em que nestes se constituem. As contribuições desse processo podem ser sintetizadas nos seguintes eixos: reconhecimento do sujeito como autor de sua prática formativa; pluralidade como marca fundamental do currículo; o aspecto relacional como núcleo do currículo; a autorização na origem e na finalidade de um currículo de possibilidades emancipatórias; formação ética e estética como inspirações transversais; e possibilidades de cultura e trabalho como centralidade formativa.

Researchers have analyzed how sport is being taught in the classroom as a regular subject and how it is accepted as a pedagogical action at school. This study aims to suggest some pedagogic proposal on the Physical Education subject to High School System which would be planned, formulated, and applied based on some critical approach on teaching, as well as analyzing and thinking over its impact on the students' learning, taking in consideration some conceptual, procedural and attitudinal dimensions to make possible for the students to become more critical so that they will understand how this subject works in contemporary time. .We had three specific blocs to develop our research: Historic, conceptual and cultural elements about sport; Public policies to sport; Individual, group and environmental characteristics. The method of this work was based on qualitative research through some research action. The study was made actually at IFRN (Federal Institute of Education, Science and Technology of Rio Grande do Norte state), in the city of Pau dos Ferros. Students from the second year of the computing course in high school were the participants in the research, there were 37 students from eleven different cities near Pau dos Ferros. They answered some questionares and a Research Diary. From the pedagogical intervention we could prove the students have improved their knowledge about the concept on sport itself, leaving the old idea about sport only as a physical practice such as an activity with rules or as competition, we could prove they have sport as a social-cultural event, involving policies, ideologies as well as historical interferences. Another aspect they mentioned was that sport is the citizens' right and as such there must be public policies pro sports. Understanding that sport transpires on peoples' habits as well as their behavior allowed us to identify its influence on our students' quality of life back in their home towns. Therewith, it is clear the necessity of a pedagogical focus on the content of Physical Education at school to make this subject more meaningful, so that the students will become more critical and reflexive about life and will be able be real citizens

Biological rhythms are part of the life from the simplest to the most complex living beings. In humans, one of the most important biological rhythms is the sleep-wake cycle (SWC), which represents an indispensable behavior for health, since sleep deprivation can lead to deficits in attention and memory, mood and daytime sleepiness which may affect school performance. Nevertheless, the SWC is a content rarely discussed in schools. Thus, the aim of this research was to address contents of the sleep-wake cycle, related to the content of Health to encourage healthy sleep habits. This study was conducted in a public school with 33 students of the 3rd year of high school and is divided into four stages: 1st) Study and analysis of the content of the textbook adopted by the school to subsidize the activities covered in the teaching unit (TU) and approximation with the biology teacher from the class to evaluated the feasibility of schedules for the development of TU; 2nd) Survey of students' prior knowledge, through a questionnaire, to guide the development of the TU; 3rd) Development and implementation of a TU based on meaningful learning and characterization of the students sleep habits, 4th) Evaluation of the TU as a viable proposal to teach biological rhythms concepts. Previous knowledge of students about the SWC are scarce and this content is not covered in the books adopted by the school. Alternative conceptions were observed, particularly with regard to individual differences in sleep, which may contribute to the occurrence of inadequate sleep habits, as reported by the adolescents in this study. The activities developed during UD were well received by the students who showed participative, motivated and evaluated positively the procedures used by the researcher. After the TU, students' knowledge about the concept of biological rhythms has been increased and they started to identify that the SWC changes throughout life and occur due biological and socio-cultural factors. Thus, the UD elaborated in this study represents a viable proposal to teach the concepts of biological rhythms contextualized to the content of Health, in high school

Scientific education has been passing by redefinitions, contestations and new contributions from the research on science teaching. One contribution is the idea of science and technology literacy, allowing the citizens not only knowing science but also understand aspects on the construction and motivation of scientific and technological research. In accordance with this idea, there is the Science-Technology-Society (STS) studies which, since the 1970s, has been contributing for science teaching and learning according to the comprehension of the relationships with society in the Western countries of the North. In Brazil, this approach began to gain projection from the 1990s when the first essays on the theme were published. Currently, there is a clear influence of this approach on the national curriculum guidelines, especially for the area of Natural Sciences, and also on the textbooks chosen by the High School National Program (Programa Nacional do Ensino Médio). However, there seems to be a gap in relation to the discussion on the specific curricular component seen in college on this approach. Thus, this study aims at adopting the approach STS, face to the preparation of complimentary educational material on acid and bases concepts studied in the course of General Chemistry of the Natural Sciences graduation program. To this end, it was performed a bibliographical research aiming at making the state-of-the-art in in these concepts in specific literature to science teaching. It is divided in two stages: systematic study (with sixteen journals chosen according to Qualis-Capes and an unsystematic study with direct search in databases and references in the papers of the systematic study. The studies had their content analyzed and the categories chosen a priori were the level of education, the acid-base theory adopted, and the strategy/theoretical frame of reference adopted. A second stage aimed at identifying attitudes and beliefs on STS (Science-Technology-Society) and CSE (Chemistry-Society-Environment) of students in the teacher and technologist training course in three diferent institutions: UTFPR, UFRN and IFRN. In this study, it was used two questionnaires, composed of a Likert scale, semantic differential scale and open questions. The quantitative data reliability was estimated through Cronbach’s alpha method, and tha data were treated according to classic statistics, using the mean as the centrality measures, and the mean deviation as dispersion. The qualitative data were treated according to the content analysis with categories taken from the reading of answers. In the third stage, it was analyzed the presence of STS and CSE content in chapters on acid and bases concepts of nine General Chemistry textbooks, frequently used in graduation programs in public institutions of the state of Rio Grande do Norte. The results showed that there are few proposals of acid and bases teaching, and they are generally aimed at High School or at instrumentation for teaching courses, and no course for General Chemistry. The student’s attitudes and beliefs show the presence of a positivist point of view based on the concept of Science and Technology neutrality and the salvation of its mediation. The books analysis showed just a few content on STS and CSE are found in the studied chapters, and they are generally presented disjointedly in relation to the rest of the main text. In the end, as suggestion to solve the absence of proposals STS in General Chemistry books, as well as the student’s positivist attitudes, it was developed some educational material to be used in the course of General Chemistry at College. The material is structured to introduce a historical view of the concepts preparation, present the use of materials, the industrial and technological processes, and social and environmental consequences of this activities

The discussion about explanation in knowledge has been made for decades. Through this course, we present different ways of understanding about what is to explain the history: the primitive ethnographic description, the chronicler, the positivist construction of a historical science and historiography of the second half of twentieth century. Nowadays this discussion needs to be continued both in the general framework of scientific practice as within educational institutions as cognitive - linguistic ability. The focus of our research is by the second approach, which is the explanation as cognitive - linguistic ability. The formation of skills, among them, the explaining one, has been studied by the authors as: (NÚÑEZ 2012; JORBA et al, 2000; SANMARTÍ and IZQUIERDO 2000). This research had as general purpose: to study the processes of formation of the ability to explain social revolution in history classes in high school, by teachers opinion and by content as this theme among history books, in order to support the continuing education of history teachers for high school. Th e qualitative based research used instruments of data collection and analysis protocol for the books prepared for this study, and interviews with teachers. For this, the techniques of content analysis and discourse referenced in Bardin and Orlandi , respec tively were used. At first, the instruments for data collection were developed and validated, while in the second, the data were collected, organized and analyzed. From the answers to the questions of the study results shows that: a) in the analyzed books - do not express the work with the definition of Social Revolution, considering the processes for the formation of this definition, the predominant type of explanation has characteristics of multicausality; proposals for teaching are characterized as eclec tic; b) while teachers speech - it is important the students know the definition of Social Revolution, the ability to explain is more linked to didactic explanation in the classroom than the explanation through epistemological sense. These results indicate that the formation of the ability to explain Social Revolution based in Cultural History approach, are not expressed in the analyzed books, but they can serve as an important resource for this purpose. The discourse of teachers has a potential pointing to the possibility of teaching organization and learning process, based on training or upgrading the explanation skill from the theory of stepwise formation of mental actions and concepts by P.Ya. Galperin. For this purpose, the research constitutes a contri bution to support the continued education of history teachers in high school.

This research seeks to reflect on the dynamics of television reception, studying the Brazilian TV miniseries Hoje é Dia de Maria, produced by Globo Television Network, and aims to generally promote inferences in the process of image reading, mainly for aesthetic reading in school context, aiming at the formation of visual proficient readers. The research was conducted with students from the third grade of a state high school, geographically located in the city of Natal, Rio Grande do Norte. The theoretical framework comes from the assumptions of cognitive social interactionism to understand language, and it is also based on the ideas of Bakhtin (1992) and Vygotsky (1998), which enabled us to understand the social interaction and the Theory of Aesthetics Reception and Aesthetic Effect with Jauss (1979) and Iser (1999), which provided a better understanding of aesthetic experience, aesthetic effects and production of meaning. The methodological approach assumes a qualitative nature and an interpretive bias, accomplished through interviews, observation, questionnaire and application of a set of investigative activities, such as introductory exposition of themes, handing out of images and mediation process. This research is the result of a research-action process in a pedagogical intervention in a state school. The results indicate that the interactional linguistic resources used by the speakers demonstrated lack of prior knowledge and repertoire regarding image reading, which initially led them to do a cursory reading. It was evident that the respondents were unaware of the initial proposal. However, throughout the meetings, it was possible to realize their transformation, because the pre-established concepts were analyzed with the help of mediation, so that the group felt more autonomous and safe to read images at the end. The survey also showed significant data, so that the school could develop new methods of teaching televisual reading.

La Escuela Secundaria es la etapa final de la Educación Básica y su objetivo es profundizar los conocimientos adquiridos anteriormente, con vistas tanto a la continuidad de los estudios por parte de los alumnos como también a su formación profesional. Considerando el carácter excluyente y elitista de la Escuela Secundaria brasileña, solo recientemente las matrículas de los estudiantes sordos comienzan a ampliarse, y los profesores se deparan con el desafío de lidiar con ese tipo de discente en aulas regulares. Tanto la política de educación especial, desde una perspectiva inclusiva, como la Ley nº 10.436/2002 – reglamentada por el Decreto nº 5.626/2005 – posibilitaron un gran salto para la educación de los sordos en el país. La primera, por la defensa de una escuela atenta a las peculiaridades y demandas de sus discentes; la segunda, por reconocer la Lengua de Señas Brasileña como medio de comunicación y expresión legítimo de la comunidad de sordos y por indicar medidas que garanticen el derecho al acceso y al éxito escolar de la población sorda dentro de la escuela. Amparado en esas discusiones, este estudio tuvo como objetivo analizar el proceso de escolaridad de alumnos sordos de una Escuela Secundaria pública y estatal del municipio de Natal, Rio Grande do Norte. Se realizó un estudio de caso de tipo cualitativo. Los sujetos fueron tres discentes sordos que estaban terminando la Escuela Secundaria, una profesora de Portugués y dos intérpretes de Lengua de Señas Brasileña. Como procedimiento de investigación, se utilizaron entrevistas (grabadas en audio y video), observaciones y análisis de documentos. La participación de los sujetos sordos demandó cuidados éticos adicionales, tales como la traducción del Término de Consentimiento Libre y Aclarado y del guion de la entrevista a la Lengua de Señas Brasileña. Los resultados apuntan que el acceso y la permanencia en la escuela secundaria fueron garantizados, no obstante había poca participación en las clases y el aprendizaje de los contenidos escolares estaba comprometido. Había traductores/intérpretes de Lengua de Señas Brasileña, los cuales, sin embargo, solo iniciaron sus actividades tres meses después del comienzo del periodo lectivo. La profesora y los intérpretes no mantuvieron interacciones que facilitasen el aprendizaje o la participación de los estudiantes, quienes se encontraban siempre juntos y en un lugar determinado del aula, sin mayores interacciones con sus pares normo-oyentes. Los discentes sordos estaban terminando la Escuela Secundaria con edades superiores a 17-18 años, los cuales revelaron no tener perspectivas de continuidad en sus estudios o de inserción en el mercado laboral. Se concluye que la escolaridad de los alumnos sordos en la escuela investigada apunta a la necesidad de una reorganización curricular que atienda a las especificidades lingüísticas y sociales de esos estudiantes.

This dissertation is a research based on the Meaningful Learning Theory, with students from the second year of High School, in the city named Capinzal do Norte, state of Maranhão. The pedagogic approach of this research focuses on what to do and how to do so students can better grasp knowledge inherent to the Euclidean Special Geometry in a more meaningful and changing way, also that information may be kept longer in their brain, so it can last longer in the present and future. The methodological strategy adopted was the research-action, followed by the constant observance of a researcher on the matter with the purpose to ensure consistent results, which come from the use of a variety of data collector instruments, such as: Concept Maps, manipulatives, educational softwares and application of evaluative tests, besides the observations made throughout the process of investigation and the diagnosis itself. It is all due to the fact that we rely on the premise that knowledge is assimilated in particular and idiosyncratic ways, which means each and every student learns in different ways and in different periods of time. That is why it is so important to develop diversified methodologies to the same subject. This research adds to the other ones related to the theoretical frameworks of the Meaningful Learning Theory, of Concept Maps, of the use of technology on the educational process and of manipulatives, which purpose is to connect their common dots. This pedagogical intervention also focuses on the construction of the educational orientations with applicability directly on class, directed specially by the Mathematics teacher of the basic education, who might use them during your teaching practice. Such guidelines established here as an educational product aim to follow the Theory's assumptions that serves as basis to this research, thus becoming an educational element with a relevant significance. The results, with which we are faced, proved overwhelming to the proposed objectives in terms of learning, which were evident in the construction of Conceptual Maps, as well as in the use of Concrete Materials, in addition to serving as a motivational element to participating students of research. The results obtained are indeed reliable in terms of learning, considered the expected goals, and made us certain that the way we have approached the subject is consistent with a holistic education and that at the same time values the tiniest details, which are fundamental to all the learning-teaching process.

The study of chemical reactions is among the most important contents to the understanding of Chemistry discipline in basic education. However, there are still few studies about chemical reactions as a complex system because, generally, this content is presented in textbooks, taught and even researched in a fragmented form. The thesis here presented aims to investigate, identify and characterize the mistakes and learning difficulties of the students about chemical reactions as a complex system, using for that purpose the analysis of the answers of 126 exams of candidates for the bachelor’s degree in Chemistry Teaching on the entrance exam for the Federal University of Rio Grande do Norte (UFRN). The mistakes and learning difficulties about the parameters ΔG°, Kp, Ea and of the calculation of the amount of substance in a chemical reaction have been identified, as well as the levels of development of the ability to interpret the chemical reaction as a system. The main theoretical source of this study is structured based on the mistakes and learning difficulties (NÚÑEZ, RAMALHO, 2012), of the chemical reactions as complex systems (NÚÑEZ, 1994; RESHETOVA, 1988; SANDERSON, 1968). As methodology, it was prioritized the analysis of the answers to the exams and the interview with the teachers. The results showed typical mistakes in the study of this subject, especially low levels and skill development. No student was able to integrate the different aspects in the systemic understanding of the chemical reaction. From the interviews with Chemistry teachers from High School, it was determined the reasons the teachers assign to those mistakes and learning difficulties. The interviews revealed that the teachers do not work in the perspective of integration of the contents which leads the students to present difficulties and make mistakes related to the content previously mentioned. The study presents a proposal for the organization of the contents of Chemistry discipline for High School as a possibility of a dialectic systemic integration of contents, understanding that this systematic vision, leads to important contributions to the development of the theoretical thinking of the students. We can mention as one of the conclusions of this study, the fact that the non-systemic organization of contents do not favor this kind of thinking in students.

In order to understand the factors involved in the improvement process of argumentative competence by students of 2nd year of high school, we undertook a qualitative approach research and interventional nature, during which we adopted the conduct of participant observation in a school belonging to the state schools of Rio Grande do Norte, located on the outskirts of the city of Natal. The analyzed corpus consisted in the interim intervention and entails the answers to a semi-structured questionnaire, fourteen opinion articles and three regrados debates, produced by the students, in addition to video recordings of ten sessions and personal notes pertaining to another six, totaling sixteen sessions observed during the school year 2014. As the most important bibliographical references we study skills and reasoning from the perspective of discursive social interactionism. Analyzing the data we loan the principle of categorization, opting for critical-descriptive presentation and were revealed to us, via the classified evidences, that among the factors involved in the study process, it appears with more relevance to set up an effective intellectual community, which meets in constant interaction subjects, which alternate assuming the conditions of speakers and audience. The constitution of this community depends largely on the teaching mediation and is indispensable to the (re)design of the studied competence, in interactions with her the subjects afforded learn and develop their competence, reshaping the limits of their zone of proximal development.

Due to demographic transition process, the educational public sector politics formers encounter a highly specific demographic situation because, nowadays, despite the demographic transition, population is still growing because of the demographic inertia; however, due to steady decline in fertility, young population tends to decrease in next years. In this way, aiming to make high school widely accessible in the country, the issue of education quality is highlighted as well the importance of the physical structure of schools and their teaching equipments to confirm a favorable or not environment for developing educational processes. In this way, this work aims to relate the enrollment of students as school types with the demand of young people who will be able to attend high school on the Rio Grande do Norte state by the year of 2020, emphasizing teaching unities structural aspects, from a school profiling to the design of three prospective alternatives. So, from INEP's Scholar Census data and IBGE population's projections, this work is composed by four stages: i) literature review about research related subjects; ii) database design and build; iii) school profiling; and, iv) prospective alternatives creation. As results, three alternatives relate potential demand and enrollment using the built profiles and they are: i) “Alternative A” attends PEE's requirements related to demands but do not provide improvements in the school structural aspects; ii) “Alternative B” points into an increase of enrollment offering to the detriment of school's structural conditions which are offered to these students; iii) “Alternative C” propitiates a quantitative enrollment increasing combined with improvements on school's physical structure. These alternatives help to support decision making related to goals and realization of universal access with physical conditions which are necessary to a favorable environment to educational activity development.

This work presents discussions on the teaching of Chemical Bonds in high school and some implications of this approach in learning chemistry by students. In general, understanding how the chemicals combine to form substances and compounds, it is a key point for understanding the properties of substances and their structure. In this sense, the chemical bonds represent an extremely important issue, and their knowledge is essential for a better understanding of the changes occurring in our world. Despite these findings, it is observed that the way in which this concept is discussed in chemistry class has contributed, paradoxically, to the emergence of several alternative designs, making the understanding of the subject by students. It is believed that one of the explanations for these observations is the exclusive use of the "octet rule" as an explanatory model for the Chemical Bonds. The use of such a model over time eventually replace chemical principles that gave rise to it, transforming knowledge into a series of uninteresting rituals and even confusing for students. Based on these findings, it is deemed necessary a reformulation in the way to approach this content in the classroom, taking into account especially the fact that the explanations of the formation of substances should be based on the energy concept, which is fundamental to understanding how atoms combine. Thus, the main question of the survey and described here of the following question: Can the development of an explanatory model for the Chemical Bonds in high school based on the concept of energy and without the need to use the "octet rule"? Based on the concepts and methodologies of modeling activity, we sought the development of a teaching model was made through Teaching Units designed to give subsidies to high school teachers to address the chemical bonds through the concept of energy. Through this work it is intended to make the process of teaching and learning of Chemical Bonds content becomes more meaningful to students, developing models that contribute to the learning of this and hence other basic fundamentals of chemistry.

For this study, a research was conducted in order to answer the question "What chemistry teaching has been developed in the Youth and Adult Education (EJA) ?". The research provides an overview of the object to the proposed changes, leading students to live with different realities and investigating the issue of contextualization based on the daily lives of these students related to the subject of chemistry. The methodology focuses ethnographic research of the case study, in which a case is studied in depth using the participant observation. In the survey data a mixed qualitative and quantitative approach was used. The work involved 6 schools that offer adult education high school; 6 directors of these schools; 6 coordinators who work in adult education; 6 Chemistry teachers and 123 students of the EJA, level high school, enrolled in the 1st, 2nd, 3rd and 4th periods. The first stage of the research consisted of questionnaires in schools where everyone involved responded closed and open questions applied to each specific group. In the second stage two schools were selected in order to conduct a deeper knowledge of adult education through practical activities of Chemistry and subsequent interview conducted in groups with students. Three teachers were also interviewed to enable a deepening of issues relating to EJA and Chemistry Teaching. The interviews were analyzed by the technique of Discursive Textual Analysis (ATD). The main issues addressed in the questionnaires and interviews were on the school structure, reasons that lead students to drop out or remained in adult education and those who make the stay, the view of those involved of the importance of chemistry discipline for students of EJA and how this should be offered. It is necessary that we need to promote changes in the chemistry class and its activities, respecting the experiences and experience already gained by the student during his life story. Another factor to be highlighted is the need for ongoing training of teachers working in adult education. Note that your continued education is given more by the experience and the ways in which they try to overcome adverse situations. The Chemistry subject taught is not agree with the principles of EJA and practiced curriculum is just an adaptation or content reduction from the regular curriculum. The improvement in chemistry teaching of EJA will take place through a dialogue between those involved in the process, clearer educational policies and willingness to implement change. Thus the teaching of chemistry contribute to the students of the EJA are actually scientifically literate and integrated into society.
