Currículo de matemática embasado na perspectiva do programa etnomatemática

Este artigo busca compreender as possíveis contribuições do trivium proposto por D’Ambrosio no intuito de se despertar um repensar sobre o currículo de Matemática, na perspectiva do programa etnomatemática. Mostra-se como se constitui um currículo embasado no programa etnomatemática pelas vertentes do trivium (literacia, materacia e tecnoracia), proposto por D’Ambrosio, no contexto da Etnomatemática. Foi feita uma revisão da literatura em várias obras de D’Ambrosio, Milton Rosa e Daniel Orey (2006), Oleneva Sousa (2016) e Kistemann Jr (2014). Dessarte, para realizar o estudo, apoia-se nos fundamentos deste programa, um ensino de Matemática no cenário da transdisciplinaridade, com viabilização e uso crítico de instrumentos comunicativos, analíticos e materiais do contexto sociocultural, estimulando a apreensão da realidade complexa pela articulação dos elementos e fenômenos que passam entre, além e por meio das disciplinas

The sobering question of this research is: in what way does the trivium proposed by D'Ambrosio, from the perspective of the Ethnomathematics Program, meet the current formative needs of the EJA? In order to answer such question, the profile of the student of the EJA was investigated of the Polivalente Tributário Henrique Silva School, presenting a rapid insertion of the historicity of the EJA in Brazil, as well as its struggles and achievements. This research presents a chronological and critical analysis of the history of the Ethnomathematics Program, its studies and its applications, as well as an in depth investigation of the aspects of the trivium proposed by D'Ambrosio: literacy, materacy and tecnoracy. To reach the objectives of the research, pedagogical interventions were made in the room of the 1st semester of the EJA High School of a state college, in the city of Goiânia. Regarding the methodology, it is an ethnographic research, whose concern is directed to the holistic and dialectical analysis of the EJA culture and the teaching of Mathematics. Data construction instruments were used: audio recordings of the pedagogical interventions and questionnaires for the Mathematics teacher and the students of the studied college. In this context, the Ethnomathematics Program was designed to teach in the transdisciplinarity scenario, with feasibility and critical use of communicative, analytical and material instruments of the sociocultural context, stimulating the apprehension of complex reality through the articulation of the elements and phenomena that pass between, beyond and across disciplines.Procuraram-se, com esta pesquisa, a compreensão e contribuição do trivium proposto por D’Ambrosio no intuito de se despertar um repensar sobre o currículo de Matemática da Educação de Jovens e Adultos (EJA), na perspectiva do Programa Etnomatemática. A questão suleadora desta pesquisa é: de que forma o trivium proposto por D’Ambrosio, na perspectiva do Programa Etnomatemática, pode suprir as necessidades formativas atuais da EJA? Para se responder tal questão, investigou-se o perfil do aluno da EJA do Colégio Polivalente Tributário Henrique Silva, apresentando-se uma rápida inserção da historicidade da EJA no Brasil, bem como sua lutas e conquistas. Constam nesta pesquisa uma análise cronológica e crítica da história do Programa Etnomatemática, seus estudos e suas aplicações, bem como uma investigação aprofundada das vertentes do trivium proposto por D’Ambrosio: literacia, materacia e tecnoracia. Para se alcançarem os objetivos da pesquisa, foram feitas intervenções pedagógicas na sala do 1º semestre do Ensino Médio da EJA de um colégio estadual, na cidade de Goiânia. Com relação à metodologia, trata-se de uma pesquisa etnográfica, cuja preocupação se direciona à análise holística e dialética da cultura da EJA e do ensino de Matemática. Utilizaram-se como instrumentos de construção dos dados: gravações de áudios das intervenções pedagógicas e questionários para o docente de Matemática e os discentes do colégio pesquisado. Dessarte, buscou-se, nos fundamentos do Programa Etnomatemática, um ensino no cenário da transdisciplinaridade, com viabilização e uso crítico de instrumentos comunicativos, analíticos e materiais do contexto sociocultural, estimulando a apreensão da realidade complexa pela articulação dos elementos e fenômenos que passam entre, além e através das disciplinas

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
