CONVENIÊNCIA DA CIÊNCIA NA POLÍTICA BRASILEIRA DE ALFABETIZAÇÃO
No full textWagner Rodrigues Silva (UFT), no sétimo artigo, “Conveniência da ciência na política brasileira de alfabetização”, apresenta uma análise das consequências de discursos fascistas na política nacional de alfabetização, discursos esses que se valem de falácias científicas como subsídios para justificar alterações na educação pública brasileira
Euclides Roxo e a Proposta Modernizadora do Ensino da Matemática Autores Aparecida Rodrigues Silva
No full textEste artigo versa sobre a trajetória profissional de Euclides de Medeiros Guimarães Roxo, professor de matemática do Colégio Pedro II, nas primeiras décadas de século XX. Discorre sobre as propostas pedagógicas para modernização do ensino secundário de matemática no Brasil, que pretendia incorporar, numa só disciplina, a aritmética, a álgebra e a geometria, até então ensinados em separado. Essas modificações foram inspiradas pelo movimento internacional de reforma da matemática, orientado pelo matemático alemão Felix Klein (1849-1925) que se mostrava presente em vários países da Europa. Além disso, Roxo apropriou-se das ideias do matemático e filósofo francês Henri Poincaré (1854-1912), defensor da filosofia intuicionista, para fundamentar suas propostas de renovação do ensino da matemática, adotadas pela reforma Francisco Campos. Para tanto, toma-se como principal fonte de pesquisa documentos que se encontram no Arquivo Pessoal Euclides Roxo (APER), utilizando-se como aporte teórico ensinamentos da história cultural. A reforma Francisco Campos, ao acatar aspectos próprios da corrente filosófica do intuicionismo, que não estavam presentes no ensino tradicional e propostos pelo professor Roxo fez surgir discussões generalizadas na sociedade brasileira, levando a uma reflexão acerca de um modelo até então aceito, sem maiores questionamentos
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
Students’ Conceptions of Engineering and its Connections with Mathematics and Science
No full textConsiderando la incorporación progresiva de la competencia STEM en el currículo de educación primaria, se exploran las concepciones del alumnado sobre la ingeniería. Para ello, se ha aplicado el instrumento validado Draw an Engineer Test (mDAET) a 18 estudiantes españoles de 10 a 11 años. Los datos obtenidos a partir de una metodología mixta (por un lado, estadística descriptiva y pruebas no paramétricas, y, por otro, análisis de contenido) muestran que el alumnado participante presenta nociones estereotipadas de la ingeniería como actividades manuales, desarrolladas en ambientes de trabajo de campo y de forma individual. Además, identifican un uso simplista de las matemáticas y no visualizan el uso de las ciencias en ingeniería. Se defiende que es necesario el desarrollo profesional docente para abordar estas concepciones y, así, avanzar hacia la educación interdisciplinar STEM o STEAM.Considering the progressive incorporation of the STEM competence in the primary education curriculum in Spain, students’ conceptions of engineering are explored. For this purpose, we conducted the validated instrument Draw an Engineer Test (mDAET) to 18 Spanish students aged 10 to 11. The data obtained from a mixed methodology –on the one hand, descriptive statistics
and non-parametric tests; on the other, content analysis– show that the participating students present stereotypical notions of engineering as manual activities developed in fieldwork
environments and individually. Furthermore, they identify a simplistic use of mathematics and fail to recognise the role of science in engineering. Teacher professional development is argued to be necessary to address these conceptions and thus move towards interdisciplinary STEM or STEAM education
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
