Hábito alimentar e percepção ambiental : um estudo de caso com estudantes do Ensino Médio em Natal-RN

This study has as objective to examine the level of perception of high school students from two private schools in Natal-RN about the existence of a direct link between alimentary habit and its effects on environmental. The research was lead with 433 students, who had their school alimentary habits investigated according to the 24-hour recall method and presents the results of data collection from their opinions on participating in the generation of industrialized solid residues and their yearnings about the improvements of the standard of the food offered in the school. The students show a high rate of grading age for level at school, traditional family structure, riding, predominantly, by car or by bus in the house-school-house way, have generally all three important meals at home, feed frequently at their school, getting it from their won school, which included, mainly, soft drinks and fried or grilled appetizers; show a good knowledge about selective collectors, however with a high variation in their correct use. They show significant approval in the existence of a connection between their alimentary habits and debased effects about environmental and consider their food compounds at school could improve the offering of health/natural food, slowing industrialized foods, which are highly used, sometimes. The study on the students knowledge and concern level with regard to the interface alimentary habit-environmental impact allowed delimitating some of the mainly involved components in the alimentary choices of the same students in the school environment, what might help to develop a set of proposals that stimulates the formation of a responsible consumption standard among teenagers and the need of a consideration about the consequences of their choices

A compreensão de reação química como um sistema complexo a partir da discussão dos erros e dificuldades de aprendizagem de estudantes do ensino médio

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.

Da arenga ao debate: o aprimoramento da competência argumentativa por estudantes do ensino médio

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.

As crenças docentes sobre a criatividade a as práticas pedagógicas criativa: o caso do programa do ensino médio inovador no RN

Estamos vivendo no século da criatividade em que os sujeitos precisam ser estimulados a criar e inovar nos processos de aprendizagem escolar. Nesse sentido, a criatividade precisa ser compreendida como um bem cultural, um direito de todos e uma condição histórica e cultural do sujeito, e não como uma capacidade inerente ao sujeito ou pertencente alguns poucos eleitos. Para que a criatividade do aluno seja estimulada, faz-se necessário, dentre outros elementos, que o conhecimento profissional do professor considere as crenças como componente de seu processo de profissionalização com o objetivo de reconhecer o seu papel e influências como formas de nortear as ações profissionais docentes. Para tanto, a presente tese tem o objetivo de estudar as crenças dos professores sobre a criatividade dos estudantes no Ensino Médio Inovador. O ensino, nessa perspectiva, mais especificamente, o ensino médio precisa inovar-se, e nesse processo, o Programa Ensino Médio Inovador PROEMI emerge como uma das iniciativas das políticas públicas educacionais vigentes. Para tanto, no intuito de fundamentar as nossas discussões dialogamos com autores que discutem a criatividade no contexto da educação, às crenças, o conhecimento profissional do professor e o ensino médio. Nessa pesquisa, 207 professores que atuam no ensino médio em escolas estaduais na cidade de Natal e sua Região Metropolitana dentro do PROEMI constituíram-se em nosso público-alvo. O instrumento de coleta de dados foi um questionário normativo de crenças contendo perguntas fechadas e abertas. Para a organização dos dados utilizamos os softwares estatísticos R. 2.15.1 e o Modalisa. O tratamento dos dados se deu mediante análises estatísticas como a análise descritiva dos enunciados, da média, do desvio padrão e a Análise de Componentes Principais ACP em relação aos resultados oriundos das perguntas fechadas e a análise de conteúdo em se tratando dos resultados referentes às perguntas abertas. Os resultados corroboraram com a tese de que os professores apresentam em suas crenças a predominância do enfoque tradicional ou clássico da criatividade, ou seja, creem-na como algo inato ao ser humano e que se desenvolve independentemente dos fatores sociais e culturais. No tocante às principais características do aluno criativo, a autonomia e o alto grau de originalidade em sua aprendizagem se destacaram, dentre outras características. Suas crenças, em relação aos elementos que inibem a criatividade do aluno apontaram que a escola, ao privilegiar os conteúdos escolares compromete a criatividade dos alunos e sobre os elementos que favorecem, destacaram-se as áreas da Arte, da Educação Física e da Literatura como disciplinas, que preferencialmente, desenvolvem a criatividade dos alunos no contexto escolar. Assim, constatamos que as crenças dos professores se configuram de forma reducionista e inatista e que precisam, urgentemente, ser repensadas para que não continue a comprometer o desenvolvimento da criatividade do aluno no contexto escolar, e nesse caso, as crenças se constituem em um dos elementos básicos da profissionalização docente que precisam constantemente ser repensadas e incluídas nas discussões sobre a formação e atuação docente, principalmente, dentro do PROEMI que tem como objetivo principal inovar e estimular a criatividade dos alunos no ensino médio

Avaliando a aprendizagem de língua inglesa em uma escola de ensino médio a partir de contribuições discentes

This study discusses the evaluation of the English language‟s learning developed in a public high school from Lajes-RN in 2011 starting from a qualitative evaluation proposal (SAUL 1988; CANAN, 1996; DEMO, 2008) aiming the production of knowledge about the evaluation process developed in the classes of English language involving the contributions from students. To diagnose and characterize the evaluation process of English language of the researched school, identifying the representations that students attributed to the evaluation, we have implemented the evaluation instruments suggested by students to perform the evaluation of language learning and allowed a reflection about the student‟s participation in the construction of the evaluation process of the English language, subject discussed by Sant‟anna (2002) and other theorists (CANAN, 1996; BRAZIL, 2002; PEREIRA, 2009). To conduct the research work, we use the qualitative approach with ethnographic basis, substantiate in authors like Bogdan, Biklen (1994), Mazzotti; Gewandsznajder (1998), Strauss, Corbin (2008) among others. The methodology was the action research (ANDRÉ, 1995; NUNAN, 2007; LANKSHEAR; KNOBEL, 2008) described as research of empirical basis which associates an action with a resolution of a collective problem, because in it, its researchers and employees are engaged in a cooperatively way (THIOLLENT, 1985). When we treat about the evaluation of English language‟s learning (ALMEIDA FILHO, 1993; SCARAMUCCI, 2009) practiced before and after the contributions made by the students of the second year of the refereed school, the study considers that high school students have a more critical and reflective conscience with regard to their evaluations, not just opining on the assessment of learning English but also about the assessment of other subjects from their scholar curriculum and so this research presents possibilities for performing the act of evaluation which consider the participation of students in decisions regarding this process, because we cogitate that when the teachers share the decisions with their students, teachers can add quality to the evaluation process

Um estudo sobre a aprendizagem de números irracionais no ensino médio

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

A aplicação dos temas transversais nas aulas de educação física - ensino médio integrado

A escola tem se guiado por ações pedagógicas do professor consideravelmente limitadas, as quais têm dificultado configurar com nitidez intenções educativas que contemplam a sua organização curricular. Nesse sentido, esta dissertação tem por objetivo apresentar uma experiência pedagógica da educação física a partir da operacionalização de temas transversais com os conteúdos curriculares no ensino médio integrado no IFRN, campus SGA. Os fundamentos teórico-metodológicos seguiram a linha qualitativa da pesquisa-ação. Participaram desta pesquisa estudantes dos cursos de Edificações e Informática do 1º ano do ensino médio integrado e a professora-pesquisadora, que é servidora efetiva do instituto. Optando pela pesquisa-ação, estruturamos uma intervenção pedagógica com intenção de promover a construção de conhecimento dos conteúdos da educação física com os temas transversais, tanto em amplitude como em profundidade, alicerçada no aporte teórico da teoria da ação dialógica (FREIRE, 2011) e da concepção aberta no ensino da educação física (HILDEBRANDT, 1986). A pesquisa teve como procedimentos a observação participante e a filmagem das aulas de educação física. As observações e os discursos dos estudantes foram organizados em categorias de questões, a saber: 1. Percepção dos estudantes sobre a educação física; 2. Sentidos e significados dos conteúdos da educação física na interfase com os temas transversais nas aulas; 3. Diálogos sobre a interação do conhecimento na relação professor-estudante. As observações e a análise dos depoimentos dos estudantes apontaram, em alguns momentos, que as aulas de educação física ainda são estruturadas no modelo rola bola , sem planejamento, configurando-se mera atividade, e não como prática pedagógica que trata dos saberes do campo da cultura de movimento. Por não constituir-se prática pedagógica que aborda os conteúdos de forma sistematizada, não se tem de forma precisa a ordenação e sequenciação dos aprendizados de práticas corporais, tampouco a introdução de temas transversais, os quais não poderiam ser aprendidos sem uma ação pedagógica concreta do professor. A interação professor-estudante afetiva e dialógica favoreceu que os estudantes se permitissem participar das experiências corporais de um jeito diferente, aceitando aprender os conteúdos curriculares em conjunto com os temas transversais, passando a perceber as aulas de educação física como espaços de experiências de movimento que lhes permitiram atribuir sentido/significado, além do conhecimento sobre o universo da cultura de movimento. A nosso ver, acrescentamos também que a escola não valorizou o trabalho com os temas transversais, pois a recente discussão sobre a inserção desses temas como temáticas relevantes, que devem ser tratadas pedagogicamente em conjunto nos componentes curriculares, ainda não é contemplada expressivamente no projeto curricular da escola

Conhecimentos sobre o corpo: uma possibilidade de intervenção pedagógica nas aulas de educação física no ensino médio

The following study aims at the main conceptions around the body and the learning through physical education classes at school. Therefore, this research mainly presents a proposal of pedagogical intervention on physical education for Ensino Médio, centered on the knowledge about the body as well as how to evaluate the impacts of such interventions on the students‟ learning process. In order to surround our field of investigation, this work elaborates the following study questions: a) What have students learned about the body in physical education classes in Ensino Médio at IFRN? b) What methodological possibilities can contribute on the experience of meaningful learning processes in physical education in Ensino Médio related to the knowledge of body aspects? Regarding to the methodology used, this ethnographic research used several instruments for data collecting like dairies, diagnostic activities, self-assessment evaluations, portfolio, filming, photographs and posts on the social network facebook. The materialization of the pedagogical intervention and all of its implications allow us to consider that the physical education classes in Ensino Médio at IFRN, campus Parnamirim have supported meaningful experiences of learning. Also they motivate relevant discussions applicable to the students‟ everyday lives once they are supported by discussions related to the influence of media about the body of teenagers, the irregular use of steroids, massaging as a possibility of body relaxation. Also, we point out that the students had the chance to experience body activities which crossed the limits of physical education classes‟ hegemony at school, such as indoor soccer, dodgeball, volleyball, basketball and handball. Thus, the students could experience body activities beyond the limits of most common sports, which started several discussions about the juvenile universe and culture. Beside the professional and personal importance of this work, we list the scientific relevance for the production of knowledge on the educational field once the number of Works about the knowledge of the body are still only a few. This study is mainly about alternative body practices. Therefore, we consider that the knowledge about the body can and must be studied not only through alternative practices, but also in different approaches which can be attributed to body running phenomenon. Finally, we believe that the discussions hereby motivated about the matter are far from being enough, so we deliver our intention in deepening this study on forthcoming researches about the knowledge of the body in the field of physical education in Ensino Médio

O PROEJA ensino médio no ifrn, campus Caicó: causas da desistência e motivos da permanência

This dissertation deals about the theme of National Integration Program of the Professional Education to the Basic Education in the form of Youth and Adults Education - PROEJA, which was developed at the Federal Institute of Education Science and Technology of Rio Grande do Norte - IFRN - Campus Caicó. It aims to analyze the causes of the abandonment and the reasons for the permanence of students within the mentioned program. To substantiate this research, we used methodologically, some procedures such as bibliographical research, documentary analysis, semi-structured interviews and focus group. To analyze the data, we discussed the contradiction that involves duality and educational compensation based in the struggles and achievements of rights at the core of public policies for high schools, for vocational education and the education of youth and adults in the 2000s. We analyze the integrated high school under PROEJA, having as reference the conception of the total human formation; the inseparability of the primary education system and vocational education and the integration of knowledge and expertise as a whole, discussing the specificities of the modality EJA, discussing the causes of abandonment and the reasons for the permanence of the students of education for youth and adults (EJA) in the primary education system. As for the results, we found that although the PROEJA be a program that aims to provide a complete human formation to contribute to the full citizenship of their graduate members, what is announced in the document that guides its creation has not been materialized in Caicó Campus. The curriculum of the course was not designed for the students of EJA, nor teachers have had an adequate training to work with these specific individuals, and its specificities of being workers with differentiated learning times have not been considered. In addition, the courses are predominantly of instrumentalist characteristics. This indicates that the material and institutional conditions to achieve the promised total and complete training have not being fully materialized at the researched school. Associated with the difficulties concerning the intra-school and extra-school conditions, personal and socioeconomic conditions which are related to the obligation to work that implies in limitations to balance work, school and family, they influenced in the interruption of the school trajectory of these subjects. Through research, we confirmed that the motives of students who remain have to do also with intraescolares conditions the quality of education (qualification of technical staff and teachers) involved in the educational process, as well as socioeconomic and personal issues represented by the support of colleagues and family.Then it is concluded that the causes of abandonment and the reasons of the permanence are of institutional, socioeconomic and personal origins. Finally, it is observed that capitalist society demands as much as possible high levels of educated workers, and at the same time makes difficult the access to that education for much of the population, and it is not randomly. The objects of that exclusion are the popular worker classes and their children

Um estudo de aplicação das teorias da expectativa e da ancoragem na motivação para o desempemho de alunos do ensino médio

This thesis presents a study on Tversky & Kahneman s (1974) Anchoring theory, and Vroom s (1964) Expectance theory in the context of education and students motivation. It is surveyed 424 students of a secondary and agricultural technical school in Brazil Northeast (EAJ). The survey form try to capture the Vroom s Expectance Theory constructs of Valence, Instrumentality, Expectation and Motivational Force, and also the Tversky and Kahneman Anchoring effect in terms of grade expected. The main findings suggest that the minimum grade required by the school is much strong in driving the students motivation and performance than the Expectancy Theory. It was found that the different grades required drive the students to pursue different grade in the same way

O ritual simbólico do Ctrl+C (copiar ) e Ctrl+V (colar) no ensino médio

Nowadays, technology has a direct influence on the relationship student and teacher have with language. The internet is a powerful tool in helping work with the language and, through it, the knowledge comes to the student easily and intensely. Furthermore, this facility has enhanced and made visible what has been called, within the University community, "plagiarism generation." This work assumes that this generation has, in their written texts, symbolic movements similar to those of "copy and paste" applied to research work carried out by high school students. Taking this as starting point, this dissertation aims to analyze how high school students of the 1st year from a school in Natal (RN) construct texts, under the movements known as "Ctrl + c" and "Ctrl + v", with reference to the text of the "other". More specific issues are behind the general objective, namely: 1. how the student appropriates the source-text when he copies and pastes? 2. What are the categories of analysis that allow us to look analytically and theoretically for the "ctrl + c / ctrl + v" practice made by the student? 2. how the studies developed in the fields of "Genetic Criticism" (Grésillon, 1987), the "school manuscripts" (Calil, 2004) and "paraphrase" (Fuchs, 1982) may help in working with writing in the classroom standing as a possible way to minimize the copy and paste effects in the students texts? Thus, we observe the categories of analysis that allow us to look, theoretically and analytically, for the symbolic ritual of the "ctrl + c" (copy) and "ctrl + v" (paste) in high school. Our study shows that the student text is a "hybrid body" whose writing is a drawing entanglement because of the presence of the foreign text, verbatim, and the presence of linguistic elements to paraphrase the original text.This textual embodiment has, behind it, certain operations, namely: replacing, moving, adding and deleting statements. Given the specificity of the data and the research objectives, this study aligns with qualitative research methods (SILVERMAN, 2009) and falls within the knowledge field of Applied Linguistics, which is characterized especially by investigating problems, phenomena in which language in a real situation is taken as central (BRUMFIT, 1995).Theoretically, our work follows the approach of studies on the paraphrase (Fuchs, 1982, 1994a, 1994b; DAUNAY, 1997, 1999, 2002a, 2002b), the studies developed in the field of Genetic Criticism (Grésillon, 1987, 1994, 1992, 2008 ) and those developed by Eduardo Calil (2004) on "school manuscripts"

A água nossa de cada dia : percepção, uso e predisposições comportamentais de alunos do ensino médio de Natal, Rio Grande do Norte

Embora a escassez de água seja reconhecida como um dos principais problemas mundiais a ser enfrentado pela humanidade, padrões comportamentais ecologicamente insustentáveis ainda persistem. Assim, o objetivo deste estudo foi analisar determinantes do comportamento pró-ambiental relativo à água, bem como os significados que lhe são atribuídos por alunos do ensino médio do Centro Federal de Educação Tecnológica do Rio Grande do Norte, em Natal. Compuseram a amostra de conveniência 315 estudantes, 146 mulheres e 169 homens, que responderam a um questionário sobre uso e percepção da água, contendo também indicadores de pró-ambientalismo, cuidado ambiental, desenvolvimento sustentável, perspectiva temporal, externalidades e coletivismo, além de inquérito sócio-demográfico. Para os participantes, água é sinônimo de vida, muito embora a relação que mantém com ela parece dúbia e, muito mais funcional que ecológica; consideram-na um recurso finito, um patrimônio indispensável à vida, contudo não foi observada coerência entre as concepções manifestadas e os comportamentos auto-relatados de uso da água. Os resultados encontrados apontaram preditores importantes do comportamento pró-ambiental relativo à água: sexo do respondente, Escala Novo Paradigma Ecológico e deixar forma de contato para participar de campanhas futuras. Seja para aprofundamento teórico em novos estudos, seja para auxiliar na elaboração de programas de educação ambiental, que poderiam contribuir para inibir os efeitos de uma cultura de consumo e de uma visão utilitarista da água, ampliando esforços individuais e coletivos para a preservação de bens comuns, como a água. Palavras-chave: psicologia ambiental; sustentabilidade; água; comportamento próambiental. x xi Abstract Although water scarcity is recognized as one of the main world-wide problems to be faced by human kind, ecologically unsustainable patterns of behavior still persist. Thus, the objective of this study was to analyze pro-environmental behavior related to water, as well as meanings associated to it by high school students of Federal Center of Technological Education of Rio Grande do Norte, in Natal. The convenience sample was composed by 315 students, 146 women and 169 men, who answered a questionnaire about use and perception of water, containing indicators of proenvironmentalism, environmental care, sustainable development, time perspective, externalities and collectivism, besides socio-demographic items. According to participants, water is synonymous of life, even though the relationship they present with it is ambiguous, much more functional than ecological; they consider it a finite resource, an indispensable life patrimony, however there was no coherence between such conceptions and the self-reported behaviors of water use. Results indicated three important predictors of pro-environmental behavior: sex of respondent, New Ecological Paradigm Scale and telephone/address left for eventual contact to participate in future environmental campaigns. They may be used in additional studies for theoretical development, or to assist in the planning of programs of environmental education, aimed at the inhibition of the effects of a culture of consumption and of an utilitarian perception of water, extending individual and collective efforts towards the preservation of common resources as water

O uso de analogias para o ensino de equilíbrio químico no ensino médio: facilitação da aprendizagem ou transmissão de erros conceituais?

The use of analogies in high school is often useful for chemistry teaching, either on textbooks or by teachers in the classroom.This use is justified by the large number of abstract concepts that rules this course. Analogies are conceptualized by several authors, which converge on the idea that these are tools that seek a way to elucidate an unknown concept by comparing it to a familiar one, relating their similar and dissimilar features. An analysis on a survey of analogies found in high school chemistry textbooks and chemical equilibrium studies is performed in order to verify whether they are leading to misconceptions for their use by students and/or for their use by teachers in the classroom, or whether they promote a learning facilitation
