Professores de ciências naturais: necessidades formativas para ensinar a medir em trabalhos práticos e experimentais

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

Literatura de monteiro lobato no ensino de ciências

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

Uma abordagem histórica para o ensino do princípio da inércia

Placed in the field of Didactic of Science, this paper proposes an approach to the introduction of the History of Science in science education, at high school level. It was designed and implemented a series of activities regarding the history of the Principle of Inertia. The aim of this approach was to give more meaning to scientific education, while opening new avenues for a better understanding of the processes of construction of scientific knowledge. The preparation of the activities involved a study of the historical development of the concept of motion, from the Aristotelian physics through physical movement concepts at medieval period, from Galileo, Gassendi, Descartes, until the first law of Newton. The strategy of teaching was applied to three classes of high school (night period) of a state public school at the city of Natal (RN). The results indicated the difficulty of overcoming alternative conceptions about movement by students. Nevertheless, we consider that the implementation of this strategy of teaching both represented gains for the learning of students, and contributed to the resizing of pedagogical practices of the teacher-researcher

Controvérsias sobre a natureza da luz: uma aplicação didática

Researches in the field of Science Teaching have shown, in recent decades, that students from high school level have difficulties in understanding basic concepts of science, in general, and physics, in particular. The specific literature indicates, as a priority for a scientific education of better quality, a more structured understanding about science. This work proposes the introduction of elements of History and Philosophy of Science in high school as an aid to learning the concepts of optics, in general, and of aspects concerning the nature of science, specifically. Making use of historical episodes regarding the controversy on the nature of light, especially during the seventeenth and eighteenth centuries, as well as clippings of the history of optics in relation to the development of models that explain the process of vision, we formulated a teaching unit and implemented it on two night high school classes of a public school in the city of Parnamirim (RN). The unit involved, primarily, the reading of three historical texts containing written questions followed by a collective debate ("moot"). The results indicated some difficulties in overcoming the misconceptions related to the process of vision and the nature of light. Nevertheless, we believe that the teaching unit has succeeded in relation to the learning of most students, both in relation to a better understanding of science as well as concepts of optics

Contribuições do Programa Institucional de Bolsas de Iniciação Científica (PIBIC) para a formação do aluno de psicologia

The undergraduate courses in Psychology have been historically pointed as defective in aspects related to the critical education and the integration between theory and practice. Hence, the scientific education has been considered a possibility to overcome those lacks. Therefore, this study has investigated the undergraduate education process of Psychology students with PIBIC (Portuguese acronym for Undergraduate Scientific Research Scholarships Institutional Program) scholarships from CNPq (Portuguese acronym Brazilian National Council of Scientific and Technological Development). The scholarship program has been a strategic tool for the undergraduate scientific research. Electronic questionnaires have been sent to all the PIBIC scholarship students of Psychology in Brazil (622; 104 have answered), containing questions about the program developed activities, tutoring and advising, PIBIC evaluation and other ones. The students scientific and academic production has also been investigated through their Lattes (CNPq s Platform in which researchers have their academic résumés). The major part of the participants (70%) has stated that the first motivation to be in the program had been their interest in the research or in the academic career. Furthermore, 60% of the scholarship students has worked as volunteers before receiving PIBIC scholarship. Among the students who have answered the research, 65,4% has reported they are tutored directly by their advisors, and 80% of them attends one or more than one advising meeting every fifteen days. It has been identified that the Psychology scholarship students do not participate in all the research activities and that the proximity with the advisor is related to the accomplishment of tasks which contributes with the student critical and reflexive education. Finally, less than 25% of the students has published scientific articles or book chapters during the scholarship, what XI demonstrates a possible exclusion of them in that phase of the process. In general, the scholarship students evaluate the program positively by revealing that it contributes with their professional and academic education. For those reasons, it is observed PIBIC s potential role for the undergraduate education in order to develop more critical psychologists able to propose innovations and contextualized practices. However, the results obtained in programs like the studied one denounce the disqualification of the provided undergraduate education for the major part of the university students, who do not have a PIBIC scholarship. As a result, it is emphasized that it there should be more investment for improving the quality of the undergraduate education itself and not only for programs which are available for few students

Educação científica e atividade grupal na perspectiva sócio-histórica

Este trabalho apresenta questões relativas à educação científica e à atividade grupal ou coletiva, na perspectiva da abordagem sócio-histórica do desenvolvimento humano e do ensino científico presente nas obras dos russos L.S. Vigotski e A.N. Leontiev. Fundamentalmente, buscaremos estabelecer essa relação a partir da proposta de Zona de Desenvolvimento Próximo realizada por Vigotski, em que o autor enfatiza o papel da imitação e da cooperação no alcance de novos níveis de desenvolvimento, processo subsidiado pela instrução, tendo como mediação o educador.

A formação para a cidadania em discursos de professores de física

Temos como mote investigativo a análise do conteúdo de discursos docentes sobre a formação para a cidadania como meta educacional. Este objetivo educacional vem ganhando força ao longo dos últimos anos. As Leis e os Parâmetros Educacionais oficiais para a Educação em Ciências, bem como a pesquisa em Educação em Ciências convergem para a proposição de formação de cidadãos críticos e participativos. Estas características de cidadãos permeiam o discurso escolar, influenciando os protagonistas da práxis educativa. Assim, investigamos sobre as concepções e proposições de docentes de Física no que diz respeito à Formação para a Cidadania. Refletimos sobre suas idéias quanto ao Ensino de Física voltado para a formação de cidadãos, de maneira que, trazemos a pauta tal tema de investigação sob a forma dos discursos de professores de Física. Para tal, escolhemos três professores de Física com base em critérios que destacassem certo comprometimento com a inovação no ensino desta disciplina. Assim, tais docentes foram entrevistados e, de suas falas, utilizamos como metodologia a Análise Qualitativa de Texto. Tal metodologia de pesquisa qualitativa nos remeteu à discussão de aspectos como as conceituações que os sujeitos investigados têm de cidadania, que relação estes depreendem entre o ensino de Física e a formação para a cidadania, bem como de fatores que influenciam ou poderiam influenciar para uma alteração no modo de conceber uma efetiva Alfabetização Científica. Como resultados, pudemos inferir: a Física concebida, pelos professores, como um fator importante na vida de um cidadão, devido ao seu caráter explicativo, utilitário e avalizador; bem como a crença que exista uma intensa relação entre a contextualização dos conhecimentos científicos com a formação de senso crítico do cidadão e sua possível tomada de decisão diante de certas situações e, também, certo grau de aproximação entre os discursos destes docentes e os existentes nos novos Parâmetros de Educação Científica; a existência de questões formativas da prática docente que auxiliam na inviabilização de propostas e estratégias alternativas, por parte destes professores, quanto a formação cidadã. Destarte, baseados em nossa análise, os resultados desta pesquisa nos leva a depreender que para uma efetiva implementação da Educação Científica visando a formação para a cidadania em escolas de nível médio, é preciso uma tomada de posição, por parte dos professores, que promova uma ruptura maior e melhor com o Ensino Tradicional e um reposicionamento epistemológico e pedagógico do ensino de Física. Além disso, incluir no Ensino de Física a formação para uma práxis cidadã embasada em conhecimentos científicos, éticos, bem como uma prática diuturna de tomada de decisão e ação social.
