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

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

Participação de moradores no programa de coleta seletiva em três bairros de Natal/RN: explorando determinantes psico-socio-ambientais

The general purpose of the study was the analysis of residents' participation in the program of door-by-door collection of recyclable residuals in Natal, Rio Grande do Norte. Even though the conception of such program by municipal managers was basically aimed at providing job opportunities and income for the collectors, the main objective of the investigation was to verify whether residents' participation could be attributed to their environmental commitment. Data collection involved three municipal districts and was performed in three stages, with complementary methodological strategies (observation, questionnaire, and interview), and characterized by selfevaluation, by residents, and hetero-evaluation, by collectors. Social, demographic, situational/contextual, and dispositional data were identified to help in the analysis of residents' adherence to the program. Separating and delivering recyclable residuals was the most frequent type of residents' participation, which demonstrates their low level of appropriation of decisions related to the program, taking part on it as passive agents. Two forms of motivation towards participating in the program were found: environmental and social. Despite the first being more frequent, it was associated to lack of environmental awareness related to the process, which may very well imply a mere reproduction of pro-environmental discourse. Motivation towards social issues was strongly connected to philanthropic forms of help. Knowledge was revealed as na important predictor for participation, as well as social networks, formed by neighbors, relatives and friends. Despite the social emphasis in the design of the program, it is possible to conclude that some residents also perceive its environmental benefits, possibly as consequence of a knowledge originated outside the program. Initiatives of environmental education should be promoted in order to minimize the allegation of lack of knowledge as justification for non-participation. Similarly, actions to put together municipal management and population would be welcome, to promote joint decisions towards sustainable styles of life

Análise das avaliações realizadas na disciplina de arquitetura atômica e molecular no curso de química, modalidade a distância da UFRN

The field of education is very rich and allows us to research in various aspects. The area of chemical education has been growing more and more, and an important aspect that has been researching this area is about the learning difficulties of students. The approach of the themes atomic structure and chemical bonds are developed in high school and have many problems that are often brought to higher education becoming an obstacle to the advancement of learning. It is necessary for these initial themes - the atomic structure and chemical bonds - are well understood by the student to the other contents of Chemistry will be understood more easily. This paper aims to describe, analyze errors and difficulties presented in the assessments of the discipline Atomic and Molecular Architecture, the students of the degree course in Chemistry - EAD, with respect to the contents of " Atomic Structure and Chemical Bonding ", by of the assessments made by the students and the Virtual Learning Environment (VLE), taking into account the activities , discussion forum and access to materials . AVA allows obtaining reports which were used to analyze regarding access / participation to assess their contribution to learning and its relation to the final result (pass / fail). It was observed that the most frequent errors in the assessments are related to the early part of the chemistry that is the understanding of atomic structure and evolution models. Students who accessed the extra material and participated in the activities and forums were students who achieved success in the course. Ie, the difficulties were emerging and the use of available teaching strategies, students could minimize such difficulties, making their performance in activities and assessments were better. Was also observed by attending the AVA, the discipline began with a large withdrawal from the page access as well as the frequency of face- evidence from observation in Listing presence of classroom assessments

Qualidade de água como tema para a socialização do conhecimento científico em região semi-árida brasileira

During the dry and rainy periods, in the Piranhas-Assu river hydrographic basin, variations in bacterioplankton and trophic state indexes were studied in the lotic and lentic environments. The means of total bacterial density wavered in the order of 107 organisms. mL-1 and they were higher in the rainy period. Cocci bacteria were numerically predominant in all sampling points, influencing the total abundance of bacterioplankton. Total bacterial biomass varied from 659 to 1997,3 µgC.L-1 due to the high values of filaments cellular volume. Total phosphorus amounted 108 µg.L-1 and it had a positive correlation with chlorophyll a (r = 0,94; p < 0,05) during dry period, when these variables presented higher concentrations. There wasn t a high spatial variation. The low transparency of water and the phosphorus and chlorophyll concentrations indicated eutrophic or hipereutrophic levels in studied points of reservoir. These variables, associated with high density and biomass values found, alert to the necessity of a constant monitoring of the semi-arid aquatic ecosystems, where the quality of water is affected by dry occurrence

Estudo das percepções ambientais e de ações educativas promotoras da biodiversidade em unidade de conservação no Rio Grande do Norte

Important issues involving the awakening to the need for conservation of biodiversity and the importance of establishing protected areas as a strategy in pursuit of environmental protection, are increasingly being developed in biological and social investigative fields. In this sense, this research aimed to emphasize the use of environmental perception of social agents are significant elements for the understanding of the man / nature, and develop educational activities aimed at raising awareness and changing attitudes towards environmental issues thus promoting reflections on Environmental Education (EE) as a critical and transformative tool for conservation of rich biological diversity. This research covers as a place of study, schools located in the Environmental Protection Area Jenipabu (APAJ), Rio Grande do Norte. Methodology in general, we highlight the use of questionnaires and mind maps as generators of the contents of empirical research, and execution of content analysis for the treatment of data collected. This dissertation has two chapters in the form of scientific articles, where the first is entitled: "Study of the perceptions and evaluation of interactions concerning environmental education in schools in a conservation area of Rio Grande do Norte - Brazil", obtaining thus a primary diagnosis for analysis about the visions that students and teachers from two schools located in APAJ have on the environment. The second article, entitled: "Effective and analysis of educational activities that promote biodiversity in a coastal area of Environmental Protection Northeast - Brazil" provides an analysis of the educational use of biodiversity as a way to raise awareness of the need for environmental conservation. It appears from research that there is a lack of training in EA by teachers, but there is a need for greater involvement of students in conservation areas, however, from the analysis of educational activities, we observed that the effectiveness of such actions acts to promote awareness and change in actors involved. Thus, environmental education needs to take into account the different perceptions found in each individual, and it can not be based solely on transmission of knowledge, so that we reach a model of conservation.

Revitalização do Rio Golandim (RN/Brasil) após décadas de contaminação por efluentes industriais e domésticos: este rio está recuperado?

Environmental pollution causes the loss of the quality of aquatic resources and also affects the health of human beings. The Golandim River is located in São Gonçalo do Amarante (RN Brazil) and had its water recovered seven years ago by measurements of parameters of the water s quality analyses physicochemistry, microbiological and heavy metals. However, it is not well established if this river is truly recovered, so this study provides a wide knowledge about the quality of these waters. Therefore, this investigation was accomplished by assays of ecotoxicology utilizing Ceriodaphnia dubia and of genotoxicity of the river s water using a biomarker Tradescantia Pallida (Trad-MCN). In set, it carried through a study of environmental perception through questionnaires that approached questions related to the profile of the interviewed one, knowledge on the environment and of the river Golandim with the community that lives in the neighborhoods of the river to diagnosis as they perceive the environment where live and its problems. The assays of the water had been carried out by collecting samples in three different sites of the Golandim River. They were collected between the periods of December 2010 (dry season in the northeast of Brazil) and July 2011 (rainy season in the northeast of). The analysis of the data allowed observing that the majority of the inhabitants are adult and presents a global vision of what it is part of the environment, the majority mentions the pollution of the river as one of the problems of the city, considering it serious. The ecotoxicology assay showed that there was not acute toxicity in all three samples collected. Meanwhile, all these three samples demonstrated significant chronic toxicity. The results from the Trad-MCN assay presented an increase in the frequency of micronucleus in one of the sites analyzed (S3) (p<0.01), in both seasons collected. On the other hand, the sites S1 and S2 did not presented a significant increase of micronucleus using this bioassay. The analyses of chemicals detected an increase in the levels of some metals, in different seasons and samples, which can be associates with some compounds found in urban and industrial areas. On the other hand, the physicochemistries parameters demonstrated that the Golandim River is recouped, when compared with the values presented at the CONAMA s legislation. However, these results indicate the presence of compounds capable of inducing chromosomal mutation in plants. On the other hand, the parameters physicistchemistries demonstrate that the river Golandim is if recouping, since when compares the values observed with the legislation of the CONAMA. All these results point to the fact that the Trad-MCN assay was sensitive and efficient biomarker for chromosomal instability and the C. dubia ecotoxicology assay was as though an efficient biomarker of toxicity of water s quality. The results from Trad-MCN associated with the ecotoxicology demonstrates that these analyses are important for environmental monitoring, once the first bioassay described above indicates alterations at the standards of cells and the other one indicates alterations at the standards of organisms. This study alerts for the necessity to carry out biological assays for the analyses of the water s quality

Morfologia e sedimentologia da plataforma continental brasileira adjacente a São Bento do Norte e Caiçara do Norte-RN/NE-Brasil

This dissertation the results of a research developed in the area of São Bento do Norte and Caiçara do Norte, northern coast of the State of Rio Grande do Norte, during the period of June of 2000 to August of 2001, in the ambit of the projects MAMBMARÉ (CNPq/CTPETRO) and PROBRAL (CAPES/DAAD). The objective principal of this research was the characterization of the sedimentary dynamics of this coast, with base in data of coastal process (winds, currents, waves and tides), with topographical risings (beach profiles and dunes), satellite images and sedimentary analyses. The more specific objectives were accomplished the coastal monitoring of this coast, to verify the maintenance of an erosive tendency or progradacional after the groynes construction for contention of the erosion in the beach of Caiçara do Norte, as well as to verify the influence of the features of bottom of the platform interns adjacent on the pole petroliferous of Guamaré. The executed monitoramento allowed to identify that the movement of the sediments, along the year, in that area, is cyclical, reaching the largest oscillations during the months of winter (deposition) and they will summer (erosion). The sedimentologic studies indicated a general tendency for sands quartzosas, with gravel presence, moderately to good selected, with asymmetry predominantly negative. In agreement with the parameter of Dean (1957), used in the identification of the state morfodinâmico of the beaches, monitored beaches, are basically reflectivas with tendency to middlemen, what frames that space of the coast norte-riograndense, as a space strongly vulnerable to erosive processes. The studies developed in the platform, it interns of this area, allowed to visualize for the first time, in large scale, the distribution of the features of the submarine bottom to the batométrico coat of 25 meters. Being pointed out the presence of a high one topographical submerged, with about 5 meters of height, 1 km of width and more than 24 meters of extension, located in the platform it interns in front of São Bento do Norte; coincident with the trend of the system of flaws of Carnaubais. This feature relay an important paper on the control of the sedimentary processes and oceanographic, as well as in the coastal evolution of this area of the RN state, and they affect the area of the pole petroliferous of Guamaré directly. These results contribute to a better knowledge of the processes in the area, and consequently as subsidies implantation of measures of coastal and environmental protection for the cities of São Bento do Norte and Caiçara do Norte, as well as to understand how the geological-sedimentary processes and oceanographic, in this area, are influencing the characteristics geoambientais of the pole petroliferous of Guamaré

Monitoramento costeiro das praias de São Bento do Norte e Caiçara do Norte RN: implicações para o pólo petrolífero de Guamaré

As parcerias entre prefeituras paulistas e o setor privado na política educacional: expressão de simbiose?

L'article présente les résultats finaux de l'enquête inter-institutionnelle qui a eu pour objet d'analyser la nature et les conséquences de partenariats conclus entre des secteurs privés et des gouvernements municipaux de la métropole de São Paulo pour le service de l'éducation à la maternelle et à l'enseignement élémentaire. La période a correspondu aux années 1996 à 2006, sachant que la perception d'une augmentation des responsabilités des municipalités pour l'offre éducationnelle, suite à la municipalisation de l'enseignement élémentaire, pourrait stimuler la sous-traitance de l'offre et la privatisation de l'éducation municipale. L'étude présente des tendances en relation avec trois modalités de partenariat: subvention publique pour l'offre de places en institutions privées de l'éducation élémentaire; acquisition de systèmes privés de l'enseignement et recours à des cabinets de conseil privés pour la gestion de l'éducation municipale. Les tendances perçues dans l'analyse indiquent que les actuelles relations entre les sphères publiques et privées dans le champ de l'éducation, suite à la décentralisation survenue dans le secteur, représentent un mouvement dans le sens de sa privatisation.

Formação dos educadores ambientais e paradigmas em transição

Este artigo trata dos pressupostos teóricos presentes na formação dos educadores ambientais nos cursos de graduação das universidades e resulta da tese de doutorado da autora. Esses pressupostos definem um quadro teórico analisado a partir do referencial metodológico do materialismo históricodialético. Esse quadro teórico pode ser organizado, pelo núcleo das representações dos professores, em concepções naturais, racionais e históricas da relação homem-natureza e da educação. A análise dessas tendências revela um movimento de superação dos paradigmas tradicionais presentes na organização curricular na universidade.

O pro-álcool e algumas relações CTS concebidas por alunos de 6ª série do ensino fundamental

A crescente degradação do meio ambiente e o reconhecimento, por parte da sociedade contemporânea, da existência de problemas considerados críticos, acentuadamente a questão energética, intensifica a preocupação em incorporar nas atividades de ensino aspectos da relação do ser humano com o ambiente. A necessidade de abordar, durante atividades de ensino de ciências, questões relacionadas com a dimensão valorativa e aspectos da relação entre ciência, tecnologia e sociedade passa a ser reconhecida tanto por educadores de maneira geral quanto por especialistas da área, de maneira particular. O movimento Ciência, Tecnologia e Sociedade (CTS) como um conjunto de propostas para o ensino de ciências é uma conseqüência concreta desta tendência. No caso do Brasil são poucas as pesquisas em ensino de ciências que exploram essa possibilidade e são poucas as experiências em termos de trabalhos em sala de aula que abordam esta questão. Este trabalho, realizado entre maio e novembro de 1996, sistematiza os dados coletados em uma classe de 6ª série do ensino fundamental que teve como tema de estudos o Projeto Pro-Álcool. Foi planejado e desenvolvido um conjunto de atividades, utilizando-se de um número bastante diversificado de procedimentos didáticos. Os resultados de pesquisa indicam que, um trabalho que ofereça aos alunos oportunidades de discussões e reflexões, a partir de procedimentos e material didático diversificado e rico em termos de solicitações e propostas aos alunos, pode promover a incorporação, em sala de aula, de diferentes dimensões relacionadas com a ciência, tecnologia, sociedade e ambiente.

As dimensões dos valores e da participação política em projetos de professoras: abordagens sobre os resíduos sólidos

Este trabalho aborda elementos relativos às dimensões dos valores e da participação política, desenvolvidos por professoras, quando da elaboração de projetos temáticos sobre resíduos sólidos. A análise representa um momento da investigação dos processos de educação continuada de professoras de séries iniciais do Ensino Fundamental, de São Carlos, SP, ao aprender e ensinar conteúdos relativos à temática ambiental, com foco nos resíduos sólidos. Apontamos na discussão dos dados que as professoras freqüentemente não reconhecem os limites da dimensão dos conhecimentos, o que provavelmente dificulta a percepção das possibilidades de desenvolvimento do trabalho com as dimensões dos valores éticos e da participação política. Analisamos, para estas dimensões, alguns aspectos que se destacaram na pesquisa realizada.

Memória de velhas professoras: a natureza e a relação sociedade-natureza

Este artigo tem como objetivo identificar, a partir da memória de velhas professoras, as concepções de natureza e de relação sociedade-natureza presentes nos depoimentos de professoras que atuaram na rede pública estadual de uma cidade do interior do estado de São Paulo, nas décadas de 1960 e 1970. Constatou-se, por meio das leituras das narrativas, que as professoras apresentam a natureza por meio de diferentes concepções. No que diz respeito à relação sociedade-natureza, evidencia-se a relação conflituosa que se estabelece entre o homem e a natureza. No geral, o homem foi apresentado como aquele que destrói a natureza, caracterizado pelas professoras como ruim e ignorante. Tentar compreender como a natureza e a relação sociedade-natureza se fazem presentes na memória dessas professoras pode contribuir para a construção de novas formas de relação sociedade-natureza nos dias atuais.

O discurso educacional católico sob a perspectiva sociológica de Pierre Bourdieu

Este artigo faz uma análise do discurso educacional católico propagado na década de 1930. Para isso, são abordados os conceitos analíticos de Pierre Bourdieu, a saber, as noções de habitus, estratégia, campo e capital cultural. O objetivo é buscar elucidar as razões e os mecanismos discursivos que engendraram as falas dos intelectuais católicos a respeito da Escola Nova e das concepções filosófico-educacionais de John Dewey. Seguindo os esquemas analíticos de Bourdieu, o discurso em questão pode ser considerado como estratégia, mecanismo pelo qual buscavam conservar o habitus do professorado consoantes com os interesses do grupo.
