AS HABILIDADES ORAIS NAS NARRATIVAS DE APRENDIZAGEM DE INGLÊS

Este texto, tendo como suporte a teoria do caos, pretende dar voz aos aprendizes de línguas estrangeiras, relatando seus desejos, suas frustrações e suas estratégias para superar os obstáculos encontrados para a aprendizagem de línguas estrangeiras. Nas narrativas coletadas pelo projeto AMFALE2, ficam muito evidentes o desejo dos aprendizes de línguas estrangeiras pelo desenvolvimento das habilidades orais e a frustração, ao relatarem as experiências em contextos formais de aprendizagem que lhes negam as práticas orais

The complexity of online collaborative writing

Abstract This paper focuses on collaboration, collective intelligence, and wiki technology in a complex perspective. It presents some results from qualitative research carried out with Brazilian university students using wiki tools to write collaborative essays. The results demonstrate that the use of wiki did not change the behavior of the majority of participants because they resisted collaboration, which is considered an essential element for the dynamicity of a complex learning system. Keywords: dynamic systems,collaboration, wiki.   Resumo Este trabalho foca a colaboração, a inteligência coletiva e a tecnologia wiki em uma perspectiva complexa. Apresenta resultados de uma pesquisa qualitativa com alunos universitários brasileiros, usando ferramentas wiki para escrita de textos de forma colaborativa. Os resultados demonstram que o uso de wiki não mudou o comportamento da maioria dos participantes porque eles resistiram à colaboração que é um elemento essencial para um sistema de aprendizagem complexo e dinâmico. Palavras-chave: sistemas dinâmicos, colaboração, wiki

Blogging: agency, mindset and literacy

In this article, we discuss the concepts of agency, mindset and literacy in order to investigate, in the light of complexity theory, three groups of teachers and their blogging practices. Our aim was to check if formal teaching of digital technologies have ‘disturbed’ the traditional literacy behavior of our participants and changed their mindsets. We visited their blogs to check if they went on blogging after the end of the course and emailed them a questionnaire to learn about their experiences with this new literacy and to collect their opinions about blogging. We realized that just a few blogs were relatively active and that the majority of the teachers had not incorporated this new literacy into their teaching practices. Nevertheless, the results do not allow us to state that those teachers have not changed their mindsets because they might have migrated to other digital contexts

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
