Videoformação de professores na licenciatura em Química : Uma ferramenta a ser compreendida e explorada
Full text linkA presente pesquisa objetiva identificar e reconhecer como a ferramenta de gravação em vídeo de prática de microensino é concebida e explorada pelos professores que lecionam o estágio supervisionado do Curso de Licenciatura em Química da Unipampa, campus Bagé, bem como as intencionalidades que os movem. Os caminhos metodológicos se constituíram por meio de entrevistas semiestruturadas com quatro professores formadores e análise documental, ancorados na Análise Textual Discursiva (ATD). Da análise, emergiram três categorias: produção e uso da ferramenta de gravação de microensino; intencionalidade da videoformação; compreensões dos efeitos obtidos por meio do desenvolvimento da prática. A partir desse movimento evidenciam-se a concepção e a expectativa dos professores, sujeitos da pesquisa e responsáveis pelos estágios, o que reflete nos processos reflexivos mais amplos da docência por meio de escritas individuais dos licenciandos em seus portfólios. A gravação e análise dos vídeos tornaram-se um método auxiliar de avaliação tanto dos professores quanto dos próprios estagiários. Aspectos mais específicos que compreendem o uso dessa ferramenta técnica como instância de problematização, significação e exploração dos conteúdos da formação teórica são pouco perceptíveis. Ou seja, as evidências são de que a ferramenta articulada a outros processos intencionalmente formativos ainda carecem de ser reconhecidas e exploradas.The present research has as objectives identify and recognize how the video recording tool in the practice of microteaching is conceived and explored by the teachers who teaches the supervised internship of the course of degree in chemistry in Unipampa, Bagé's campus, as well as the intentions that moves them. The methodological paths were constituted by semistructured interviews with four teacher trainers and documental analysis, anchored in the Discursive Textual Analysis (DTA). Of the analysis, emerged three categories: production and use of microteaching recording tool, intentions of videoformation and comprehensions of the obtained effects through the practice development. From this movement are evidenced the conception and the expectation of teachers, research guys and internship teachers, what turns to broader reflexive processes of teaching by means of individual writings of the graduation students in their portfolios. The video has become an evaluation auxiliary method both of teachers as of the interns themselves. More specific aspects who comprehends the use of this technique tool as instance of problematization, signification and exploration of theoretical formation contents are little perceptible. In other words, the evidences are that the tool articulated to other intentionally formative processes still in need of been recognized and explored
Formação de professores e desenvolvimento de currículo na área de Ciências da Natureza e suas Tecnologias acompanhado pela pesquisa
No full textTrata-se de pesquisa de mestrado, em fase inicial, que objetivou investigar o potencial formativo da ferramenta de áudio-gravação pelo grupo de pesquisa (GEQPC) da Universidade Federal do Rio Grande, Brasil (FURG). Este grupo aposta na formação de professores e desenvolvimento de currículo na área de Ciências da Natureza e suas Tecnologias (CNT), através de parcerias instituídas na interface universidade e escola, na constituição do professor-pesquisador de sua prática. Apresentam-se três categorias emergentes do procedimento metodológico de Análise Textual Discursiva (ATD), o qual fez uso da transcrição de um dos encontros de planejamento: Tema e temática interdisciplinar; Conteúdos e conceitos científicos; Currículo e pesquisa. A áudio-gravação mostrou-se uma ferramenta de mediação potente, que possibilitou a tomada de consciência das concepções que orientou o planejamento curricular
Compreensões da prática de gravação em vídeo de microensino na formação de professores de Química
Full text linkEsse estudo, como parte de pesquisa de mestrado, objetivou identificar e reconhecer como a ferramenta de gravação em vídeo de práticas de microensino é concebida e explorada pelos professores formadores que lecionam os estágios supervisionados do curso de Licenciatura em Química da Universidade Federal X, bem como as intencionalidades que os movem. Os procedimentos metodológicos de produção de dados consistiram em entrevistas semiestruturadas com os professores de estágio supervisionado do curso, e a análise dos dados seguiu os passos da Análise Textual Discursiva de Moraes e Galiazzi (2007). A partir da categoria emergente “compreensões dos efeitos obtidos por meio do desenvolvimento da prática”, se evidenciou que os docentes ainda não possuem clareza teórico-metodológica quanto à finalidade das gravações da prática de microensino articulada ao seu uso como ferramenta mediadora
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
