The thesis has its largest array in the reorganization of science that is built from the middle of the last century and its horizon reconnection between scientific culture and humanistic culture, and the dialogue between science, art and literature. This epistemological regeneration view of the scientific paradigm incorporates the poetic language and sociological analysis, and brings out a complex, open and transdisciplinary narrative. To undertake this exercise as interlocutors we have thinkers like Nietzsche, Lévi-Strauss, Edgar Morin and Bruno Latour, to name a few, and as a reference for analyzing the entire artistic production of one of the icons of Brazilian music, Clara Nunes. It is problematized up in this work, through the singer s discography, lyrics and fragments of her biography, the construction of a social character that politicized culture, increased the mestizo consciousness of popular imagery, and exceeded the excessively prosaic narratives of the academic and scientific culture. The central argument of the thesis recognizes a Hybrid Subject Clara Nunes, as indeed is what is expected of the politically engaged intellectual in the 21st century

The environment, which fundamental importance has already been recognized in all the world, is an actual national and international discussion subject, whose interest grows for the society, and consequently to the Law, in order to prevent the natural resources to the present and future generations. The 1988 Brazilian Constitution, recognizing the importance of the environment, treated about it in many of its parts, even dedicating a specific chapter (Chapter V About Environment, inserted in Title VIII About Social Order). The brazilian constitutional text established to everyone the fundamental right of enjoying an equilibrated environment, obligating the State and all society to defend and preserve the environment to the present and future generations. The economic growing process, that predominated and still persist in the big majority of the countries, where is practiced the capitalist system, has in the enterprises (legal persons) one of its main actors. Many times, these enterprises, especially in the actual globalized world in where we live, where the gain of money is priorized, ends, at the moment they act, making damages to the environment. These damages are, many times, considered by the law. crimes against the environment. The 1988 Brazilian Constitution, according to the Modern Criminal Law, realizing that many crimes were being committed by the enterprises, established in article 225, §3rd, the criminal responsibility of the legal persons. Almost ten years after the 1988 Brazilian Constitution, was published the Law number 9.605/98, in which third article established the penal responsibility of the legal persons that practice crimes against the environment, without excluding the individual responsibility

The soil macrofauna is influenced to several biotic and abiotic environmental factors, from changes in the physical environment to a variety of interactions among the species involved, affecting the patterns of biodiversity of soil fauna. The power and specificity of the mechanisms that act on soil organisms vary greatly depending on environmental conditions at different scales of space and time. The Caatinga has great spatial heterogeneity of vegetation, climate and soil, so the soil macrofauna would follow this local spatial variation in the environment? This study aimed to investigate the effects of local environmental variables on biological parameters (taxa richness, total abundance and biomass) of soil macrofauna in a fragment of caatinga in João Câmara, Rio Grande Norte, Northeast Brazil. The study was conducted in the Cauaçu farm, where a grid of 2000m x 500m was drawn, and later, 30 sampling points were randomly selected. The methodology used to collect the macrofauna was the TSBF method. We tested the effects of 10 environmental variables on macrofauna across the plots and across the layers of soil. The hypothesis that macrofauna soil responds to changes in the environment was not supported throughout the plots, but was confirmed to soil layers. The soil macrofauna shows a pattern of concentration in the surface layer and decreases considerably in the deeper layers. This pattern had significant and positive relationship with the aerial plant biomass and fine root stock. The aerial plant biomass releases plant necromass that accumulates in the surface layer, providing an important source of resource and shelter for soil macrofauna, explaining their greater abundance in this layer. The roots are used as a means for the arrival of nutrients to the soil from the primary production, thus a greater amount of root conditions higher food intake for macrofauna, especially the herbivores

Os efeitos de ano e época de nascimento, propriedade, sexo do bezerro, regime alimentar, idade do bezerro e idade da vaca ao parto, os efeitos aditivos direto e materno da raça Charolesa e o efeito de heterose materna entre as raças Charolesa e zebu foram avaliados pelo método dos quadrados míninos sobre características de importância econômica, como peso, perímetro escrotal e escores visuais de conformação frigorífica, de umbigo e de pelame à desmama em bovinos da raça Canchim. Utilizaram-se dados de 12.334 animais Canchim nascidos de 1999 a 2005. O ano e a época de nascimento, a propriedade, o regime alimentar e a idade da vaca ao parto (linear e quadrático) tiveram efeitos significativos sobre todas as características estudadas. Houve efeitos do sexo sobre o peso do bezerro à desmama e o escore de umbigo; da idade do bezerro sobre peso, perímetro escrotal e escores de conformação frigorífica e de pelame; e das proporções de Charolês no bezerro e na mãe sobre o peso, a conformação frigorífica e a qualidade de pelagem; e da heterozigose materna sobre peso, perímetro escrotal e escores de conformação frigorífica e de umbigo. Os efeitos aditivos diretos da raça Charolesa como desvio do zebu foram negativos sobre peso, conformação frigorífica e qualidade da pelagem à demama, enquanto os efeitos aditivos maternos foram positivos. Os efeitos heteróticos maternos foram positivos sobre peso, perímetro escrotal e escores de conformação frigorífica e de umbigo. em geral, essas fontes de variação devem ser consideradas nas estimativas de parâmetros genéticos e nas avaliações genéticas dos animais Canchim para as características estudadas.

This thesis is the result of an investigation about the transversality of the environmental issues into the daily curriculum of High Schools (from first to eighth grade). The research field was the county of Santo Antonio de Jesus in the state of Bahia, Brazil. The investigation is related with the challenge that the present model of social development and organization has put to the school institution: to bring the regular discussion about Environmental Education (EE) to the school s daily life. Facing the complexity of the socio-environmental issues and the basic functions of Education, the object of study was restricted to the identification of the challenges and paradoxes of the EE inside the curriculum organization of Politic-Pedagogic Project of the schools and the teachers daily practices. About the methodology, we adopted different references for the qualitative research: sociology, history, economy, and education. As for the investigative procedures about the teacher s practices, we related the school s daily practices to the context of the community. We also adopted several investigative procedures, such as questionnaires, interviews, observations and formative intervention. The theoretical basis was organized based on references to curriculum organization, environmental culture, teacher education and also considering the pillars of a capitalistic system that is based on consumerism and that generates social exclusion. At the initial considerations, we contextualized the contemporary environmental issues in an attempt to interpret the conditions of the EE transversality into the school s daily practices, which are still oriented to the traditional Cartesian Education. Based on the collected data, we found the reasons for the teachers dilemma and reluctances to the insertion of the environmental issues into the organization of the work plan and into the management of a school. Nevertheless, the results also signed promising possibilities to the EE tranversality, in case the curriculum of the school could be more sensible towards the cultural and social-economical issues of a community. We especially questioned The National Curriculum Parameter s (PCN), which is considered highly insufficient to inform the teachers about the environmental issues, facing the actual local conditions of social and pedagogic work. The final considerations showed the role and the importance of this research as one strategy to organize the curriculum education into the perspective of the transversality of environmental issues inside the education of both teacher and student

This study focuses on the initial formation of the pedagogue in college, especially the formation that takes place in the Pedagogy Course. It is bound by the following question: what senses are attributed by the Pedagogy Trainees regarding the relation between the Education Science knowledge and the Pedagogic Practice knowledge developed in the Pedagogy Course of UESB, in order to build up teaching knowledge and practice? Therefore it aims to reflect on the relations between the Education Science framework and the Pedagogic Practice under the supervised classes that belong to the Pedagogy Course. It presents the implications and contextualizations concerning the pedagogue formation as a historic and cultural process, emphasizing the current moment of this formation. It is based on the idea that the senses trainees, future pedagogues, attribute to their own formation process reflect on the learning of theorical and practical knowledge that validates the process of teachers formation, especially the pedagogue formation. Accordingly, it believes that the senses attributed by the students of teachers initial formation courses regarding the Education Science knowledge and Pedagogic Practice knowledge are essential as organizers in the construction of teaching knowledge and practice while the supervised classes take place. The theorical and methodological option is based on the studies of Qualitative Epistemology by Gonzalez Rey. Empiric studies took place at the Pedagogy Course of Universidade Estadual do Sudoeste da Bahia (UESB), located in the city of Vitória da Conquista/Bahia. The students who took part in this research were six graduating ones, enrolled in the last two semesters of the referred course, stage when the supervised classes happen. The procedures used in the organization of collected information consist of analysis of documents such as the mentioned course curricular project and the students reports, besides interactive and provocative talks to the students. The results show the senses students attribute to Educational Science theorical basis to practice to Pedagogic Practice opportunity of feeling as if they were teachers and to the relation between Education Science and Pedagogic Practice opportunity of experiencing the relation between theory and practice. Besides, the theorizations students have about the relation between theory and practice in teachers formation are also presented. Consequently, it is emphasized that the supervised classes are the moments in which the trainees might understand the relations between thought and pedagogic practice, building the senses attributed to the relation between the Education Science knowledge and the ones of Pedagogic Practice as organizers in the teaching knowledge and practice. In this context, the trainees build some knowledge regarding what it means to be a teacher, which is not written or published, due to its subjective dimension, but circumscribed in their pedagogic practice while the supervised classes take place and when professional teaching practice becomes effective

This paper presents a research realized with Physics, Chemistry and Biology teachers, and it aimed to evaluate: 1) the development level of those teachers regarding the abilities that make possible to teach high school students about how to measure in practical and experimental work; 2) the formatives necessities regarding those abilities; and 3) the order of priority for teacher´s formation regarding those abilities. The study is based on the activity theory, from A. N. Leontiev (1983), since we considerer the teacher´s formation a kind of activity for which the category necessity is source of motivation and in which is a necessary condition for professionality and for the professional development. A questionnaire with open and closed questions was applied to 116 teachers during three pedagogic workshops realized to dynamize the science laboratory. The instrument allowed us to obtain the personal and professional profile of the participants, as well as their development level, their formative necessities and their order of priority about the teaching of the abilities related to the work of testing measuring hypothesis, regarding: a) to operationalize variables of a hypothesis in experimental work; b) to measure in practical and experimental work; c) to estimate possible measuring mistakes and use proper procedures to minimize them; d) to estimate the validity of a measuring; and e) to estimate the confiability of a measuring. The research results indicated some limitations of the teachers about their development level in all the analyzed abilities. More than 90% of the teachers considered those deficiencies as necessities of the continuing formation. Most of them (about 54%) expressed immediate priority for formation in each one of the abilities. From a correlation, using the statistic chi-square test, between the development level and the formative necessities for the five abilities, the obtained results allow us to assure that, for all those teaching abilities, there is a strong correlation between the development level and the formative necessity. This situation is symptomatic of the importance of approaching more the science teaching and the teacher´s formation on practical and experimental work in high school as key-component of scientific education in basic education. The obtained results can contribute, as subsidy, for continuing formation courses, having as base the necessities that constitute motivation elements of the teachers for professional development

In contemporary society, distance education is expanding, especially in the offering of courses of initiatory professor training. By the side of possibilities, there is the need to critically reflect on the government decision to finance, and even to incite distance education, as a more economic way to achieve, within different time and space, the greatest quantity of the population, trying to fill the gaps of the Brazilian school education. The research was made in the Biology Bachelor Course offered by the Pernambuco University (UPE), in the context of the Presential Support Pole of the Paraiba State University, located in the city of Campina Grande. Along this study, we intend to analyze the evaluation practice and the instruments of valuation available in the virtual environment of learning (AVA), used by the former professors in the learning evaluation of the contents offered by the reference course. The relevance of the discussion is to reflect about the results of distance education in the initial of the professor training. To perceive the possibilities and limitations concerning the technological resources available at the educational process, especially to the evaluation practice, is primordial in order to comprehend the contents of learning that can be explored by the professors and which is the dialogical relation that is firmed between professor, preceptor and student, in favor of the learning development and an effective and meaningful education. The qualitative research had the symbolic interacionism as a methodological-theoretical approach. We gathered informations through institutional documents, documental records, questionnaires and semi-structured interviews. Treating and analyzing the data we used the content analysis method (Bardin, 1977). As a theoretical basis, we relied on authors such as Zabala (1998, 1999), Aretio (2002), Hoffmann (2003, 2005), Silva, M. (2003, 2006), Belloni (2006), Luckesi (2008), Silva, J. (2008), Vasconcelos (2008) and Domingos (2009). It was evident the need to reflect about the educational practice of the professors and preceptors responsible for the academic distance learning, concerning the evaluation of the learning contents in a autonomous and innovatory way, identifying its influence in the development of values which are considered vital to a complete professor upbringing. The evaluation in a mediator approach is necessary to the reality of an online classroom, because of its character to promote the improvement of the action of the one who is teaching and the one Who is learning in an interactive, collaborative and cooperative perspective, seeking a transformative praxis. Involved in this formation, the bachelors will be able to promote the development of capacities and skills necessary to the complete learning of theirs future students, certifying the education for life, which is a perspective that includes the knowing, the knowing how to do and how to be, a living being with sustainable relations with the others and with nature

Located at the intersection of Science Education, Teacher Training and use of didactic Comics (HQ), the text aims to discuss the problem which thus sets: - What is the contribution of the incorporation of comics in the continuing education of teachers Natural Sciences of the early years of elementary school? - May be the comics for enabling science teaching? - How to contribute to a reflexive training of teachers of the early years? - In order to answer these questions, there was a collaborative action research in a school located in the city of Natal / RN, with three teachers who teach natural science in the early years of elementary school. The study involved the conduct of 13 meetings of in-service, under the focus on reflective practice, with the purpose of discussing topics underlying the teaching of science and the use of comics as a methodological strategy. All meetings were recorded on audio and transcripts. The teachers finally recorded the meetings by writing a portfolio. The teachers made use of 10 sessions with reading comics in science classes, which were video recorded and later watched by the educators in autoscopy sessions followed by individual interviews. From the collected data, several aspects that have emerged can be grouped into three categories: The difficult concept of science, teachers' work and the obstacles and possibilities of comics as a teaching strategy. In this sense, are woven assessments taking as its founding, look for the reflective and dialogic practices exercised in the classroom. In the analysis of the data, we can see the conceptual difficulties, methodological and pistemological questions of teachers for teaching science, but also the limitations of comic books for teaching. Learning more relevant appointed by the teachers is related to the importance of collective work to mitigate the training needs of teaching. Finally, signals that the HQ has a great potential for use in science classes, provided that the teacher conduct a careful planning for this, but that the meetings of continuing education promote moments of reflection on teaching practices that are capable of giving rise to new attitudes before the difficulties they depict

Advocating education as a humanizing task, the humanizing function of literature and the importance of scientific education, this paper proposes linking Science and Literature in Science Teaching using two specific books of Monteiro Lobato in the final series of elementary school level. Adopting the action research methodology, an interdisciplinary approach, we used the books A Reforma da Natureza and Serões de Dona Benta in two classes (8th and 9th) at Escola Estadual Professor José Mamede, located in the town of Tibau do Sul, Rio Grande do Norte. The readings were performed in Portuguese Language s course and the scientific content were discussed in Science´s classrooms. The book A Reforma da Natureza permitted to approach issues related to the environment, while the use of Serões de Dona Benta showed particularly its effectiveness in questioning the concepts of matter, mass, weight and some questions about the Nature of Science (NOS). In general, the analysis of results shows that the readings of these two books permitted interaction and dialogicity in the classroom, as well as indicates the potential of these books in contextualing and questioning the scientific content contained in it. We advise, however, the need for the science teacher be aware of the conceptual mistakes present in literary works, avoiding erroneous learning and reinforcement of alternative conceptions

Situated at the intersection of Continuing Formation, Science Teaching and content of astronomy, the research aims to discuss this problematic : What are the challenges encountered in a continuous formation in service of science teachers of the early years of elementary school with contents of astronomy? Aiming to answer this question, we carried out a collaborative action research in a school of Natal / RN, with 6 teachers who teach or lectured Natural Sciences in the early years of elementary school. The study involved 14 encounters of continuos formation in service, to enable a better understanding criticism and propositive concerning the teaching science, especially some content of astronomy for the initial years, through a shared discussion. To this end, we consider that more profound understanding of astronomical knowledge allows the establishment of relationships and connections between theoretical knowledge and the daily teaching practice. All discussions were recorded on audio and transcripts. This research was realized using questionnaires and diary, however, the audio recording was its principal working instrument. About the data collected, several issues emerged as the little field of conceptual content, several misconceptions among teachers about the content of astronomy, lack of adequate space in the school environment to study and the need for collective reflection on the practice. Finally, is indicated that the contents of astronomy should be used in classrooms of Sciences, provided that teaching plan of action consider the existence of diverse alternative conceptions about the subject, among both teachers and students, and the need of permanente continuing education in the teaching
