O presente relatório transparece o progresso de aprendizagem e reflexão realizado no âmbito da Prática de Ensino Supervisionada em Educação Pré-Escolar e no 1º Ciclo do Ensino Básico. Neste, evidenciou-se uma reflexão da prática educativa que teve como finalidade compreender de que maneira se poderão potenciar as aprendizagens das Ciências Naturais nas crianças. Para tal, destacam-se alguns objetivos que estiveram bastante presentes na dimensão investigativa, tais como a promoção de ambientes de aprendizagem na área das ciências físico-naturais tornando as crianças observadores ativos com competências para investigar, experimentar e aprender; a promoção de contextos de aprendizagem participativa e ativa, desafiadoras e motivantes; o conhecimento e compreensão dos conhecimentos prévios destas, refutando assim a sua expressão e dúvida através do questionamento; e por fim, a promoção de atitudes, competências de ação, competências metodológicas e competências de comunicação nas crianças em relação à aprendizagem de acontecimentos naturais. Assim sendo, a principal finalidade desta investigação-ação nos contextos onde se realizou foi compreender processos associados à (re)construção de conhecimentos com base nos saberes que as crianças já tinham, construindo eu própria saberes profissionais, através da minha própria ação, registada, analisada e fundamentada; ABSTRACT: The following report transpires the progress of learning and reflection that was accomplished within the Supervised Teaching Practice in Preschool Education and in Primary Education. In this, it showed a reflection of educational practice that aimed to understand how it may enhance the learning of Natural Sciences in children. For such, we highlighted a few goals that were very present in the research dimension, such as, promoting learning environments in the area of physical and natural sciences, making children active observers with powers to investigate, experiment and learn; promoting ways of participation and active learning, challenging and motivating; knowledge and understanding of prior knowledge of these, thus disproving your expression and doubt through questioning; and finally, the promotion of attitudes, action skills, methodological skills and communication skills in children with regard to the learning of natural events. Therefore, the main purpose of this research-action, in ways where it was accomplished, was the reconstruction of knowledge based on the awareness that children already contained, building my own professional knowledge, through my own action that were recorded, analyzed and justified.

Objetivamos identificar e caracterizar nos Projetos Político-Pedagógicos (PPPs) dos cursos da área de saúde da Universidade Estadual do Ceará (Uece) as estratégias usadas para estruturar o currículo relacionando e integrando ensino e pesquisa. Serviram como fonte de consulta os PPPs dos cursos e as legislações nacionais para o ensino superior. São ao todo 16 disciplinas de Metodologia da Pesqui sa: 5 em Enfermagem, 4 em Ciências Biológicas e Educação Física; 2 em Nutrição; 1 em Medicina. Apenas o curso de Educação Física apresenta continuidade de oferta das disciplinas durante a gradu ação. Quanto à ementa das disciplinas, observa-se uma lógica de concentração de informações técni cas nas disciplinas introdutórias nos semestres iniciais e nas de aplicação em semestres posteriores. Constatam-se mudanças positivas, como a implantação de disciplinas de monografia, mas somente a exigência do ensino da metodologia científica no currículo da graduação e do trabalho monográfico não é suficiente para incorporar a pesquisa ao ensino. Há necessidade de adequações curriculares e avaliação continuada dos PPPs.

RESUMO A Anatomia Humana (AH) é uma disciplina básica para todos os estudantes dos cursos superiores das áreas da saúde e biológica. A maior parte a considera de conteúdo difícil. O ensino da AH precisa ser repensado no contexto da política atual de acesso amplo ao ensino superior. E corresponder ao dever das instituições de proporcionar ao estudante uma formação de qualidade com vistas à formação de um profissional crítico e de perfil criativo frente às distintas situações do cotidiano. É preciso entender possíveis fatores que levam às elevadas taxas de reprovação nesta disciplina. Portanto, o objetivo do presente estudo foi relacionar o resultado do vestibular/Enem com hábitos de estudo e desejo profissional no desempenho acadêmico da disciplina dos alunos dos cursos de Educação Física, Ciências Biológicas e Nutrição do IF Sudeste MG. Foram entrevistados 129 alunos. A pontuação do vestibular/Enem foi maior entre os aprovados em AH; não houve entre os grupos diferença quantitativa nas horas de estudo e tampouco na escolha do curso, que ocorreu por opção do aluno (versus por falta de opção).

The brazilian-plum (Spondias tuberosa, His) is a tropical fruit tree that has been consolidated in the market for agribusiness processing, due to its characteristic flavor of fruit. Accordingly, studies to optimize the propagation of plants are necessary for production of seedlings with agronomic and quality assurance measures. This study aimed at determining the efficient techniques for uniform seed germination, as brazilian-plum seed present mechanical dormancy, and establish optimal culture media for multiplication of shoots from the in vitro micropropagation. Firstly, in a greenhouse at the Universidade Federal do Rio Grande do Norte, was evaluated the influence of different methods of breaking dormancy in the emergence of seedlings of brazilian-plum and speed of germination (IVG) of seeds. After 60 days of cultivation, it was found that splay in the distal portion of the seed was the best treatment, with rates of 85.33% in germinability and 3.415 of IVG, compared with the treatment of seed-soaking in water for 12h + humus and the control group. Subsequently, new sources of seedling explants were obtained in studies of tissue culture. Laboratory of Plant Biotechnology that the university, was used stem apex, nodal segments and internodes in search of decontamination with various concentrations of calcium hypochlorite [Ca(OCl)2] and micropropagation, inoculating them in half WPM (1980) with various concentrations of 6-benzylaminopurine (BAP). We used 10 sample units with three replications for different concentrations of [Ca(OCl)2], BAP and explants type. After thirty days, which was observed for the control of contamination, during the establishment in vitro, concentrations of [Ca(OCl)2] between 0.5% and 2.0% were effective in combating exogenous contamination of the apex. In nodal segments and internodes, concentrations of [Ca(OCl)2] between 1.0% and 2.0% and 1.5% and 2.0% were respectively, sufficient to reduce the percentage of losses in these infestations explants. For micropropagation, the culture medium supplemented with 0.1 mg.L-1 BAP promotes better development of multiple shoots per explants from nodal segment. However, success does not get to shoot training in internodal segment

The research aimed at investigating the dimensions and the universe of social representations of environmental education, as well as identifying the senses and meanings Environmental Education. This study admitted as presumption the education and environment dimensions. In this investigation was adopted as reference the dimension or representation scope of Moscovici. One hundred and twenty (120) students from Public Schools of Basic Education participated of this study and moreover three hundred and twenty-three (323) from Higher Education in the area of the UPE-FACETEG. The following questions were admitted: 1) What are the dimensions/categories that exist in the semantic scope of social representations of the environmental education? 2) What are the senses and meanings of environmental education? 3) The student s representations of Basic Education are similar or different from the Higher Education? The software EVOC helped in the organization of semantic scope for construction of the categories, with support of the contents analysis. The justifications are sorted on lexical classes using the software ALCESTE, through of the speech analyses. The free association of words answered the question dimension/categories and its semantic scope, being: a) Nature/Environment; b) values; c) Attitudes; d) Actions; e) Implications; f) Mediation. Six lexical classes were found with its meanings enumerated in this way: 1.Awareness, as a factor of belief for the preservation of nature and society. The students are clamoring for environmental education in the school, emphasizing the importance of awareness in the development of the respect to the environment linking the education and family; 2. The consciousness-knowledge relationship for the environment-nature preservation. 3. The environment and human interventions, in search of indicators of solutions. 4. Nature /background/ environment and its constituting elements, a thinking of values and an acting for mediation. 5. The human-nature interaction in social representations of environmental education and the symbolic-life size. 6. Nature / environment /, values, attitudes, actions, implications, and mediation in nature-man relationships. The groups more representatives according to these lexical classes were, the Basic Education in the class-4, represented exclusively by the Primary and Secondary Education and the class-6 represented by both two the Basic Education (47,37%) and the Higher Education (52,63%) - History, Pedagogy, Psychology, Mathematics, Language and Literature. The classes 4 and 6 are related to the class-3 which in turn is formed by students of Higher Education (Mathematics, Biology, Pedagogy, Psychology, Language and Literature) and Basic Education (Primary and Secondary Education). The Higher Education is most represented by the lexical classes (1, 2 and 5). The class 2 corresponded to 80% of the researched groups. In the class-1 the biggest representation was concerning to the Psychology, Geography, Biology and Language and Literature courses, whereas the class-5 was best represented by Psychology, Biology, Pedagogy, Language and Literature, Geography and History. From the results, one may conclude that the imagery is nature/environment; that life is the symbolic dimension that permeates the whole imaginary, and that preservation, awareness and respect are inserted in the speech that circulate to protect life

Most knowledge and techniques developed by mankind since ancient times had the main purpose to study and understand the various phenomena of Nature. Science, like one of these narratives, works as a translation, transcribing what, is systematically observed. Within the set of transformations on the modern sciences, the dialogue with related areas became quite narrow and, occasionally, functional, and the dialogue with non-related areas, in turn, does not takes place by any matters. The focus of this research is the teaching of Biological Sciences, and the undergraduate courses as strategic places to disseminate a broad understanding of Nature, that broadens the conceptual relations between different disciplinary axes, previously fragmented. In order to do so, I take a four-way metaphorical approach as a methodological construction base. Three of them proposed by Joël de Rosnay, represented by artifacts: The Telescope, The Microscope and the Macroscope. And finally, a proposition that complements the approach, that i named The Naked Eye. In Telescope, which allows a more general construct of a phenomenon, I discuss the teaching of Biological Sciences in Brazil. In the microscope, which allows us to analyze in detail a scenario, I construct a rank of the major courses in biological sciences and propose a discussion on the understanding of nature on the undergraduate programs. In Macroscope, who allows, at the same time, zoom in and out to the phenomenon observed, I call for a transdisciplinary dialogue, based on the authors Ilya Prigogine, Basarab Nicolescu, Henri Atlan and Bruno Latour, which can certainly contribute to the curriculum of the Biologists training programs, that builds knowledge pertinent to a complex observation of Nature. I complete the set of the quaternary reading and understanding of the world from the Naked Eye, as the first strategy of perception in our species. For this, I invite the philosopher of Nature Chico Lucas da Silva as my interlocutor

O presente artigo apresenta os resultados de uma pesquisa cujo objetivo foi identificar as percepções dos professores de Biologia do município de Piracicaba, SP, e dos alunos concluintes de um curso de licenciatura em Ciências Biológicas em relação à presença da Educação Ambiental em sua formação inicial, a fim de discutir a inserção da temática na universidade em geral e, especificamente, na licenciatura em Ciências Biológicas. Os resultados indicam que o professor de Biologia ainda necessita de uma formação mais crítica em relação à educação ambiental e que, numa perspectiva complexa, essa formação necessita ser tratada de forma mais rigorosa na universidade e nas licenciaturas em Ciências Biológicas para que os profissionais formados possam atuar, efetivamente, na formação cidadã para uma sociedade mais sustentável.

Learning difficulties can have a direct influence on the teaching-learning process of students by reducing their school performance. One factor that may contribute to this negative influence on learning refers to the presence of alternative conceptions, which may have different origins in the educational process. It is of paramount importance, for teachers, for example, to identify the concepts and the difficulties of their students in order for that knowledge can be able to contribute significantly to improve the teaching and learning process. From the following considerations, the present study (still in progress) aims to investigate aspects related to the concepts and difficulties of graduating students in relation to the contents of Biology. The participants of the research were undergraduate students in Biological Sciences from UFRN, studying by Distance Learning (Educação a Distância). To develop the survey, questionnaires were developed to identify the contents in Biology that these students have more difficulties as well as an interview to raise misconceptions regarding the content of cytology. Another tool developed was a textbook evaluation form, which was applied in conjunction with a questionnaire in workshops (short courses) in order to identify possible errors and mistakes that could jeopardize the process of teaching and learning, such as the importance that these learners assign to textbooks in the educational process. From the data collected, a booklet on the content of cytology was developed as a product. It is expected that it can be applied in classrooms in order to improve the teaching and learning in references to Biology, to minimize, for example, alternative conceptions than can occur related to the theme

A presente pesquisa apresenta as perspectivas de atuação profissional de alunos do curso de Licenciatura em Ciências Biológicas de uma universidade pública do estado de São Paulo. Por meio de entrevistas semiestruturadas, levantamos as expectativas desses alunos em relação ao curso que frequentam e qual identidade construíram como parte do imaginário que compõe o ethos. Verificamos que o curso de licenciatura pesquisado pouco contribui para a construção de uma identificação dos alunos com a profissão de professor de Biologia e/ou Ciências e, apesar de constituir-se em um curso de formação para tal, acentua a construção da imagem do cientista- pesquisador nas áreas básicas da Biologia.
