Episòdios de aprendizagem situada e multiletramentos. Na escola, na pessoa e na formação.
No full textComo uma nova metodologia de ensino pode contribuir para transformar certas práticas educativas e estimular práticas inovadoras? Entre conceitos, reflexões e experiências, Episódios de Aprendizagem Situada e Multiletramentos na escola, na pesquisa e na formação apresenta a metodologia EAS, inédita no país, ancorada em outras relações com a cultura na sala de aula, em que expressividades, olhares, gestos, conhecimentos e reflexões construídas com o uso de artefatos tecnológicos e culturais traduzem experiências de significação, pensamento crítico, formação e transformação na escola e fora dela.Na primeira parte, apresenta a pesquisa e um quadro teórico e sociocultural da Metodologia de Episódios de Aprendizagem Situada (EAS); os fundamentos, princípios e estrutura didática, bem como suas relações com os multiletramentos, as competências midiáticas e digitais e as aprendizagens de crianças e jovens no contexto da cultura digital e uma síntese dos resultados da pesquisa.Na segunda parte, compartilha diversas experiências e práticas mídia-educativas, artísticas e culturais construídas em diferentes espaços, que traduzem e reinterpretam aspectos da metodologia a partir de diálogos entre pesquisadores, professores e estudantes.Voltado aos professores(as) e pesquisadores(as) que buscam novos horizontes na relação entre educação-tecnologia-arte-cultura, reafirma-se a escola como espaço ético e estético da formação humana, e o processo de ensinar e aprender como potência de conhecimentos, saberes e fazeres singulares e plurais. Num momento em que a escola é cada vez mais instigada a inovar e a responder à complexidade dos novos desafios da vida contemporânea, este livro é um convite a pensar uma nova metodologia de ensino que caminha nessa direção
Prefacio al libro "Projeto UCA. Entusiasmo e desencantos de uma politica publica"
No full textThe contribution aims to give a framework to a research, held in Brazil, about a Public Program of technology integration in the schools. The Project was about utilization of microcomputers (like XO built by MIT) in order to foster teaching and learning in urban and rural areas. The results presented in the book are about the States of Bahia, in North-East of the Country, and Santa Catarina, in the South

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
Redox-switchable atom transfer radical polymerization
No full textTemporal control in atom transfer radical polymerization (ATRP) relies on modulating the oxidation state of a copper catalyst, as polymer chains are activated by L/CuI and deactivated by L/CuII. (Re)generation of L/CuI activator has been achieved by applying a multitude of external stimuli. However, switching the Cu catalyst off by oxidizing to L/CuII through external chemical stimuli has not yet been investigated. A redox switchable ATRP was developed in which an oxidizing agent was used to oxidize L/CuI activator to L/CuII, thus halting the polymerization. A ferrocenium salt or oxygen were used to switch off the Cu catalyst, whereas ascorbic acid was used to switch the catalyst on by (re)generating L/CuI. The redox switches efficiently modulated the oxidation state of the catalyst without sacrificing control over polymerization
