Feiras de ciências no ensino médio: atuação dos professores no contexto da prática
Get PDFIn our work, we analyze how teachers act in the Scientific Initiation Policy of high school students, directed to the science fair. We discussed the meanings of Science Fair from the perspective of the teachers, seeking to notice how the educational politics proposed by the local agents is operated in two public schools located in the city of Mossoró, Rio Grande do Norte state. We used as technical-methodological reference the approach of the politics cicle of Ball and Bowe (1992) and enactment theory of Ball (2016), enabling us to intertwine many performatic possibilities present in the science fairs, given the disputes, resistance, accomodations and teacher's criations in the practical context. We used, for the realization of the study, qualitative research, whose instruments were the literature review, documental analysis and half strutured interview. We conclude, although in a contingent and provisional manner, that the teacher's performance in the science fair is "multi performative", behaving fabrications, adaptations, resistances, abstention and criations from the politics related to the contexts located in the schools, defence of disciplinary demands and professional interest of each teacher.Em nosso trabalho analisamos como os docentes atuam a política de Iniciação científica de alunos do ensino médio voltada para as Feiras de Ciências. Discutimos as significações das Feiras de Ciências a partir do olhar dos professores, buscando perceber como a política educacional proposta pelos agentes locais é atuada (enactement) em duas escolas da rede pública estadual de ensino médio, situadas no município de Mossoró, Estado do Rio Grande do Norte. Utilizamos como referencial teórico-metodológico a abordagem do ciclo de políticas de Ball e Bowe (1992) e a teoria da atuação de Ball (2016), nos possibilitando entrelaçar diversas possibilidades performáticas presentes nas Feiras de Ciências, dadas as disputas, resistências, acomodações e criações docentes no contexto da prática. Para a realização do estudo, realizamos pesquisa qualitativa, cujos instrumentos foram a revisão de literatura, análise documental e entrevista semiestruturada. Concluímos, ainda que de maneira contingente e provisória, que a atuação docente nas Feiras de Ciências é “multiperformática”, comportando fabricações, adaptações, resistências, abstenções e criações da política relacionadas aos contextos situados das escolas, defesa das demandas disciplinares e interesses profissionais de cada professor.Trabalho não financiado por agência de fomento, ou autofinanciad
Desafios para a ado??o do enfoque CTS em pr?ticas pedag?gicas da educa??o b?sica: as percep??es dos professores
No full textThe contemporary world is marked by great scientific-technological development
achieved by humanity associated with the ethical, social and environmental problems. In this context,
this paper aims to know how teachers in continuous training perception the STS approach and
how they intend to use them in their pedagogical practices. The research problem arises from the
need to understand how teachers scale the relations between scientific and technological development
and ethical issues, social and environmental associated with it. A qualitative approach was
adopted, in which we analyzed the responses of these teachers to the written assessment applied
in STS discipline, of the Specialization Course in Education and Contemporaneity in IFRN/Mossor?.
The results show that after the training, the teachers present theoretical notions about STS, but
still find it difficult to implement this knowledge into their teaching practices.A contemporaneidade ? marcada por grande desenvolvimento cient?fico-tecnol?gico
alcan?ado pela humanidade associado a problemas ?ticos, sociais e ambientais. Nesse contexto, o
objetivo deste trabalho foi estudar as percep??es dos professores da educa??o b?sica, em curso
de forma??o continuada, no que diz respeito aos estudos em CTS e, ainda, quais os desafios para a
ado??o desse enfoque em suas pr?ticas pedag?gicas. O problema de pesquisa surge da necessidade
de entender como os docentes dimensionam as rela??es entre o desenvolvimento cient?fico e
tecnol?gico e os problemas a ele associados. Como metodologia adotou-se uma abordagem qualitativa,
na qual foram analisadas as respostas dos citados docentes ? avalia??o escrita aplicada na
disciplina CTS, do Curso de Especializa??o em Educa??o e Contemporaneidade do IFRN/Mossor?.
Os resultados apontam que, ap?s a forma??o, os docentes apresentam no??es te?ricas sobre CTS
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
