MAGMATISMO PÓS-TECTÔNICO INVESTIGADO POR MEIO DOS MÉTODOS GEOCRONOLÓGICOS U-Pb E Lu-Hf, COMPLEXO PEDRA BRANCA, RIO DE JANEIRO – RJ

O Complexo Pedra Branca está localizado geograficamente na zona oeste da cidade do Rio de Janeiro e está inserido tectonicamente no Domínio Costeiro, pertencente ao Terreno Oriental da Faixa Ribeira Central. Os litotipos que formam o Complexo foram gerados em eventos relacionados a Orogênese Brasiliana (~600 Ma), abrigando assim rochas pré- a- pós-colisionais. O estudo de corpos graníticos pós-tectônicos na Faixa Ribeira revela que o magmatismo ocorreu em dois pulsos distintos, com intervalo de aproximadamente 30Ma entre eles. O presente estudo analisou 9 amostras do Complexo Pedra Branca, por meio dos métodos geocronológicos U-Pb e Lu-Hf, referentes às litologias granito Pedra Branca, possível representante do pulso mais antigo e granito Favela, possível representante do pulso mais jovem, a fim de melhorar a compreensão do magmatismo pós-tectônico na região. Os resultados, em sua maioria, corroboraram com os anteriormente descritos na literatura, porém indicaram que o magmatismo no complexo, ocorreu na forma de pulsos progressivos, diminuindo o tempo de intervalo esperado para o mesmo (~20Ma). O indicador petrogenético εHf indicou participação de fontes crustais e mantélicas, dando caráter bimodal ao magmatismo.

Zika, dengue and chikungunya population prevalence in Rio de Janeiro city, Brazil, and the importance of seroprevalence studies to estimate the real number of infected individuals.

In the last 40 years, Latin America countries, including Brazil, have suffered from the emergence and reemergence of arboviruses, first Dengue (DENV) and recently Zika (ZIKV) and Chikungunya (CHIKV). All three arboviruses are currently endemic in Brazil and have caused major outbreaks in recent years. Rio de Janeiro city, host of the last Summer Olympic Games and the Football World Cup, has been specially affected by them. A surveillance system based on symptomatic reports is in place in Rio, but the true number of affected individuals is unknown due to the great number of Zika, Dengue and Chikungunya asymptomatic cases. Seroprevalence studies are more suitable to evaluate the real number of cases in a given population. We performed a populational seroprevalence survey in Rio, with recruitment of a sample of volunteers of all ages and gender from July to October 2018, within randomly selected census tracts and household. A total of 2,120 volunteers were interviewed and tested with rapid immunochromatographic test for ZIKV, DENV and CHIKV. Individuals with positive results for IgG and/or IgM from only one virus were classified accordingly, while those with test results positive for both ZIKV and DENV were classified as flaviviruses. We corrected for sample design and non-response in data analysis, and calculated point estimate prevalence and 95% confidence intervals for each virus. Arbovirus prevalence in the Rio's population (n = 6,688,927) was estimated at 48.6% [95% CI 44.8–52.4] (n = 3,254,121) for flaviviruses and at 18.0% [95% CI 14.8–21.2] (n = 1,204,765) for CHIKV. Approximately 17.0% [95% CI 14.1–20.1] (n = 1,145,674) of Rio´s population had no contact with any of the three arboviruses. The reported cases of Zika, Dengue and Chikungunya by the current surveillance system in place is insufficient to estimate their real numbers, and our data indicate that Zika seroprevalence could be at least five times and Chikungunya 45 times bigger. The high number of individuals having never been infected by any of the three arboviruses, may indicate a proper scenario for future outbreaks.

A evolução cética da filosofia na ficção de Machado de Assis ao longo de quatro encontros na Rua do Ouvidor

São analisados no artigo quatro encontros na Rua do Ouvidor do narrador ficcional e protagonista de quatro narrativas de Machado de Assis. As narrativas são examinadas diacronicamente de modo a mostrar a evolução de uma perspectiva cética ao longo da ficção machadiana. Cada encontro sinaliza uma etapa na construção dessa perspectiva. No Primeiro Encontro são apresentadas as condições prévias ao surgimento da perspectiva cética na segunda fase. Examine-se o conto Felicidade pelo Casamento publicado no início da primeira fase da obra do escritor, no qual a aparência se contrapõe à realidade, caracterizando uma perspectiva dogmática. No Segundo Encontro, destacado das Memórias Póstumas de Brás Cubas, romance que inicia a segunda fase e a perspectiva cética, a aparência penetra até o âmago da realidade, caracterizando uma perspectiva pascaliana. No Terceiro Encontro, flagrado no romance Dom Casmurro, a aparência obscurece a realidade, caracterizando uma perspectiva cética clássica. Enfim, no Quarto Encontro, presente no último romance de Machado, o Memorial de Aires, a aparência é o objeto e alvo último da percepção, caracterizando uma perspectiva cética-estética original machadiana. O artigo começa com uma apresentação da importância da Rua do Ouvidor na obra de Machado em geral.

P050 Work Disability, Indirect Costs and Risk Factors in Patients With Crohn's Disease in a Rio De Janeiro Tertiary Care Center.

BACKGROUND: Crohn's disease (CD) is considered one of the most expensive disorders in Europe and the prevalence and incidence of CD is increasing in Brazil in the last decades. During flares, CD can lead to the inability to work with social and economic impact. This study aimed to assess the indirect costs, prevalence and risk factors for work disability in the state of Rio de Janeiro (RJ) and in a tertiary care referral center of the state (UERJ). METHODS: Analysis was performed using the database of the Single System of Social Security Benefits Information (SUIBE), with a crosscheck for aid pension and disability retirement from 2010 to 2018 in RJ state. Demographic characteristics included sex, age, work status, geographic region, days off work, average monthly benefit, and ICD-10 K50 with all subdivisions. A sub-analysis was performed on CD patients from UERJ during the same study period using prospectively collected data from the database, analyzed retrospectively to investigate potential risk factors associated with absence from work among CD patients. Additional demographic and clinical characteristics including sex, age, disease duration, disease location, predominant disease phenotype, perianal disease, extraintestinal manifestations, smoking history, prior medications (steroids, immunosuppressants and biologics), duration of biologic use, history of abdominal surgery (defined as the need for bowel resection), prior spontaneous abdominal abscess, previous appendectomy, and Montreal classification were analyzed. RESULTS: In RJ state, the estimated prevalence of CD was 26.05 per 100,000 inhabitants, while the associated work disability was 16.6%, with indirect costs (focusing on losses related to employment) of US$ 8,562,195.86. Permanent disability occurred more frequently in CD patients aged 40 to 49 years. In UERJ, the prevalence of work disability was 16.7% and the risk factors for absence from work were predominantly disease duration, the A2 profile of the Montreal classification, abdominal surgery and rectovaginal fistulas. Mood disorders were observed in 19% of these UERJ patients, with a mean interval of 3 years between diagnosis of CD and the first benefit. CONCLUSION: The prevalence of work disability in UERJ CD patients is similar to RJ state and may reflect other regions from Brazil. The risk factors are associated with disease duration and complications of disability. The prevalence of psychiatric manifestations has called attention to potentially neglected aspects of CD, and the need to incorporate specialized multidisciplinary care. Rehabilitation programs are still deficient in the country. The increase in the prevalence of CD in Brazil and the resultant socioeconomic impact of a chronic disease affecting relatively young patients, emphasizes the importance of providing quality medical care in order to mitigate the burden of CD. Early diagnosis and full medical therapy might prevent most of the complications that lead to repeat hospitalizations and surgical interventions and the consequent incremental direct and indirect costs associated with CD.

NGS-based typings for 7 HLA loci in three populations from Rio de Janeiro, RJ, Brazil

We investigated HLA class I (HLA-A, -B, and -C) and class II (HLA-DRB1, -DQB1, -DPA1, and -DPB1) alleles by NGS-based typing among 759 Brazilian individuals from three populations in the Rio de Janeiro city based on their self-declared skin color (Caucasian, N = 521, AFND-ID: 3730; Parda, N = 170, AFND-ID: 3728; Black, N = 68, AFND-ID: 3727) to calculate allelic and haplotypic frequencies, plus linkage disequilibrium. Only HLA-DRB1 locus deviated from Hardy-Weinberg equilibrium (in Caucasian and Black populations). The three populations shared the most frequent allele on HLA-A, -C, -DRB1, -DPA1, and -DPB1. Genotype and frequency data are available in the Allele Frequencies Net Database.

Co-Circulation of Two Independent Clades and Persistence of CHIKV-ECSA Genotype during Epidemic Waves in Rio de Janeiro, Southeast Brazil

The Chikungunya virus infection in Brazil has raised several concerns due to the rapid dissemination of the virus and its association with several clinical complications. Nevertheless, there is limited information about the genomic epidemiology of CHIKV circulating in Brazil from surveillance studies. Thus, to better understand its dispersion dynamics in Rio de Janeiro (RJ), one of the most affected states during the 2016–2019 epidemic waves, we generated 23 near-complete genomes of CHIKV isolates from two main cities located in the metropolitan mesoregion, obtained directly from clinical samples. Our phylogenetic reconstructions suggest the 2019-CHIKV-ECSA epidemic in RJ state was characterized by the co-circulation of multiple clade (clade A and B), highlighting that two independent introduction events of CHIKV-ECSA into RJ state have occurred between 2016–2019, both mediated from the northeastern region. Interestingly, we identified that the two-clade displaying eighteen characteristic amino acids changes among structural and non-structural proteins. Our findings reinforce that genomic data can provide information about virus genetic diversity and transmission dynamics, which might assist in the arbovirus epidemics establishing of an effective surveillance framework.

Diversity of tomato-infecting begomoviruses and spatiotemporal dynamics of an endemic viral species of the Brazilian Atlantic rain forest biome.

Yield losses induced by a complex of begomoviruses are observed across all major tomato-producing areas in Brazil. Tomato severe rugose virus (ToSRV) is the most widespread begomovirus in the country. Conversely, tomato common mosaic virus (ToCmMV) displays a more restricted geographical distribution to areas associated with the Atlantic Rain Forest (ARF) biome, encompassing the States of Espírito Santo-ES, Minas Gerais-MG, and Rio de Janeiro-RJ. Here, we characterized 277 tomato-infecting isolates collected in fields located within the ARF biome from 2006 to 2018. ToSRV displayed the highest prevalence (n = 157), followed by ToCmMV (n = 95) and tomato interveinal chlorosis virus (n = 14). Fourother begomoviruses were also detected, but with very low incidences. ToCmMV was the predominant begomovirus in the ARF biome up to 2014-2015 with very low ToSRV incidence. Subsequently, ToSRV became the most prevalent species in ES and RJ, but ToCmMV was still predominating in the "Zona da Mata" meso-region in MG. Due to the remarkable endemic distribution of ToCmMV, we carried out phylogeographical studies of this virus using information from all 28 available isolates with complete DNA-A sequences. The closest common ancestor of ToCmMV was more likely originated around Coimbra-MG area ≈ 25years before the formal report of this viral species. So far, all surveys indicated tomatoes as the only natural hosts of ToCmMV with outbreaks occurring mainly (but not exclusively) in highland areas. ToSRV shows a more widespread incidence across both highland and lowland areas of the ARF biome.

Managerial Strategies for Long-Term Care Organization Professionals: COVID-19 Pandemic Impacts

This paper aims to analyze the strategies that healthcare professionals have adopted during the coronavirus pandemic (COVID-19) in long-term care organizations in Rio de Janeiro city, Brazil, by investigating their competencies—mainly managerial ones. To reach its goals, this paper performs empirical research and theoretical research. For the empirical research, the plans of professionals during COVID-19 pandemic in long-term care organizations are observed, and a questionnaire is applied to analyze observed data integrity. The data are analyzed through the Python and IBM SPSS Statistic programming languages, and descriptive analyses use descriptive statistic proportions, rates, minimum, maximum, mean, median, standard deviation, and coefficient of variation (CV). A non-parametric approach performs repeated measure comparisons using Wilcoxon’s test, while the McNemmar test is used to repeat the categorical variables. Statistical significance is assumed at the 5% level. For the theoretical research, a literature review is developed using scientific databases. The results show that for the searched period, the number of deaths and the number of people infected by COVID-19 in these organizations are low when compared to general statistics of Rio de Janeiro city. This paper concludes that these strategical adoptions have brought significant benefits to long-term care organizations, and it might motivate researchers to develop future studies related to long-term care organizations, helping to fill the literature gap on the subject.

Performance of CCCma and GFDL climate models using remote sensing and surface data for the state of Rio de Janeiro-Brazil

The performance of the CCCma (Canadian Centre for Climate Modelling and Analysis) and GFDL (Geophysical Fluid Dynamic Laboratory) models in the baseline period (1961–2000) and for the future IPCC scenario Representative Concentration Pathways (RCP) 6.0 (2046–2065) were evaluated through the descriptive statistics using spatial interpolation methods (Kriging and Ordinary Co-Kriging) using the exponential, gaussian and spherical spatial models. The daily temperature and rain data from the CCCma and GFDL models were used for the current baseline climate (1961–2000) and the future scenario (2046–2065), data from the National Oceanic and Atmospheric Administration (NOAA) were used for comparisons with the two models and the product MCD12Q1 derived from Moderate resolution spectroradiometer sensor was used to check which areas had higher and lower values of temperature and rain in the State of Rio de Janeiro. For validation, data were compared and geostatistical analysis was performed using Kriging techniques. The averages of air temperature and precipitation showed similar patterns in both models. The CCCma model presented the data closest to the NOAA reanalysis data, with the GFDL model underestimating most precipitation and air temperature data. Through the product MCD12Q1 of the MODIS sensor, it is possible to register marked differences in relation to rain and temperature and their respective land use for the State. For the geostatistics data, it was possible to verify that, for the past and future scenarios, the exponential transitive model presented in the majority of the cases the least degree of spatial dependence (GDE), being therefore considered the best. When comparing the GDE of the two climatic models, it is verified that the CCCma presented the best geostatistical performance and can be used in works to simulate scenarios of future climate changes.

Notes on the bionomy of two spider wasp species in an urban forest fragment in Brazil

There are few studies dedicated to the natural history of Neotropical spider wasps (Pompilidae). When it comes to urban areas, the knowledge on these wasps is even scarcer. This study sheds light on the natural history of Auplopus cf. rufipes and A. cf. brasiliensis (Hymenoptera: Pompilidae: Ageniellini) from an urban Atlantic Forest fragment in the Rio de Janeiro Botanical Garden, Rio de Janeiro City, Brazil. Auplopus cf. rufipes displays a multivoltine pattern and frequently nests in bamboo canes scattered in the open areas, whereas A. cf. brasiliensis is a rare sight, with only a single nest collected from a hose trap-nest. Females of the former species show aggressive behaviour, which suggests a solitary lifestyle. Their nests were partly enveloped in a complex structure, similar to other species that build free-standing, unconcealed nests and display some degree of sociality. Such behaviour could not be observed for A. cf. brasiliensis. Despite that, nests of both species were built using mud pellets, though the brood cells differed regarding arrangement and position in the trap. Two parasites were found attacking the cells: Caenochrysis crotonis (Chrysididae) in a cell of A. cf. rufipes, and Chaenotetrastichus neotropicalis (Eulophidae) in two cells of A. cf. brasiliensis, both recorded for the first time. Auplopus cf. rufipes was found to prey on Frigga cf. quintensis (Salticidae), the first record of this genus as a host of Auplopus.

Objetivos: avaliar a atenção no pré-natal pelo enfermeiro; analisar a consulta de enfermagem na percepção da gestante. Metodologia: pesquisa exploratória, descritiva, qualitativa, desenvolvida em uma Clínica de Saúde da Família do Município do Rio de Janeiro. A população do estudo consistiu em 15 gestantes, usando referencial avaliativo proposto por Avedis Donabedian. Resultados: o estudo apontou gestantes jovens, casadas, sem incentivo do enfermeiro na participação do parceiro, porém classificando positivamente a consulta pré-natal. A sala de pré-natal possui equipamentos necessários, mas o registro no cartão da gestante foi inadequado. Conclusão: necessário maior incentivo da presença paterna nas consultas e uniformidade nos registros do cartão da gestante com qualificação do enfermeiro na assistência prestada.

Radon concentration and radiation exposure levels in workplace buildings of downtown Rio de Janeiro City, SE, Brazil

Radon, a noble radioactive gas, can reach levels that pose a risk to public health in poorly ventilated environments such as residences and buildings. It is a known carcinogenic agent, responsible for the incidence of about 14% of lung cancer in the world. In this work an evaluation of indoor radon, that downtown Rio de Janeiro workers are exposed in working daily life was carried out using an alpha detector (RAD7). The indoor radon concentration and effective dose are below the limits recommended by international standards.

Exposure to pyrethroid insecticides among pregnant women and their child in Rio de Janeiro City - Results from a birth cohort (PIPA Project)

Background/aims: Pyrethroid insecticides are largely used in Brazil, one of the world's largest consumers of pesticides. We investigated the exposure of pregnant women and their child at the time of birth and 3rd month of life to pyrethroids and its association with sociodemographic variables, self-reported diseases, and childbirth outcomes in the City of Rio de Janeiro. Few studies investigate levels of pyrethroid in neonates.Methods: We performed a cross-sectional analysis of data from Rio birth cohort (PIPA study). Pregnant women at 3rd trimester who received antenatal care at the Federal University of Rio de Janeiro’s Maternity School. Mother’s sociodemographic, daily habits, existing disease and some birth outcomes about child was collected. Mother's (n=138), newborn's (n=29) and 3-month old child's (n=46) urine samples was analyzed for detection of pyrethroid metabolites 3-PBA and 4-FPBA using liquid chromatography coupled to mass spectrometry. We did a descriptive analysis of the excretion profile of pyrethroids from mothers and their children.Results: From all samples, 70% of woman, 28% of newborns, 30% of 3 months old children showed urinary concentrations of pyrethroid metabolites. Pyrethroid metabolites geometric mean (GM) was 0,78 ng mg-1 for mothers, 0,16 ng mg-1 for newborns and 0,89 ng mg-1 at 3rd month old. Mother’s pyrethroid levels doesn’t seem to have relationship with child’s pyrethroid levels at follow up. Pregnant women with diabetes excreted higher levels of pyrethroids in the urine (p<0,01); newborns small for gestational age (SGA) excreted higher levels of pyrethroids in the urine (p=0,01); similarly, cephalic perimeter and Apgar was associated with pyrethroid exposure in 3rd month old babies (p=0,02; p=0,02).Conclusions: Newborns (28%) presented pyrethroids metabolites in urine even at birth. Pyrethroid exposure appears to be related with diabetes in mothers, withsize for gestational age in newborns and with cephalic perimeter and Apgar in 3 months old child.

Natimortalidade de fetos com peso de 2.500g no municí­pio do Rio de Janeiro: 2008-2017

Este estudo visa descrever aspectos assistenciais das mulheres que tiveram natimortos com peso maior ou igual a 2.500g e que morreram antes ou durante os seus nascimentos, de mães residentes no municí­pio do Rio de Janeiro (MRJ) nos anos de 2008 a 2017. Trata-se de um estudo descritivo, retrospectivo, utilizando dados secundários, integrando variáveis relacionadas aos óbitos destes bebês, a partir dos dados secundários dos Sistemas de Informação sobre Mortalidade (SIM) e Nascidos Vivos (SINASC). A coleta dos dados ocorreu durante os meses de janeiro a março de 2019. A taxa de natimortalidade no perí­odo estudado foi de 10,1/1000 nascidos e a taxa de natimortalidade de fetos com 2500g ou mais foi de 2,42/1000 nascidos. A faixa etária materna mais frequente foi de 20 a 34 anos, a escolaridade de 4 a 11 anos de estudo, o parto vaginal foi a principal via de nascimento, o sexo masculino apresentou maior frequência de natimortalidade, a grande maioria dos óbitos foi antes do parto e tiveram como local de ocorrência, os hospitais. As afecções originadas no perí­odo perinatal foram as mais prevalentes e o declí­nio dos óbitos não investigados se deu em 2010, possí­vel relação com a obrigatoriedade da vigilância destes óbitos a partir deste ano.

VULNERABILIDADE À CONTAMINAÇÃO DE AQUÍFERO EM ÁREA URBANA – AQUÍFERO GUARATIBA, RJ

O método DRASTIC é um método amplamente aplicado para avaliar a vulnerabilidade intrínseca de um aquífero com base nos parâmetros: profundidade, recarga, tipo de aquífero, topografia, impacto da zona vadosa, solo e condutividade hidráulica. Porém estudos indicam que esses parâmetros são insuficientes para caracterizar aquíferos inserido em área urbana, assim, o método DRASTICA foi desenvolvido com a adição do parâmetro de impacto antropogênico. Este trabalho apresenta o estudo da vulnerabilidade do aquífero Guaratiba na cidade do Rio de Janeiro, com base no DRASTIC e sua adaptação DRASTICA com a utilização de amostras de concentração de nitrato nos poços indicando a qualidade da água subterrânea. O mapa de vulnerabilidade DRASTIC mostrou três classes, com predominância das classes baixa e média enquanto 0,8% da área de estudo apresentaram alto índice de vulnerabilidades. O mapa DRASTICA mostra a predominância da influência das atividades antrópicas, uma vez que a classe de alta vulnerabilidade possui 5% da área de estudo. No DRASTICA, observa-se a presença de alta vulnerabilidade nas maiores concentrações de nitrato e, além disso, as amostras com a menor concentração de nitrato estão ausentes nessa classe. Portanto, conclui-se que, para estudos de vulnerabilidade do aquífero em áreas urbanas, é indicado o método DRASTICA.

Perfil epidemiológico das gestantes com sífilis no Rio de Janeiro

Objetivo: Descrever o perfil epidemiológico das gestantes diagnosticadas com sífilis no município do Rio de Janeiro (2009–2018). Metodologia: Estudo epidemiológico, descritivo e retrospectivo transversal, realizado na Plataforma on-line do Ministério da Saúde, Departamento de Informática do Sistema Único de Saúde (DATASUS). Os dados referentes a sífilis em gestante do município do Rio de Janeiro advêm da série histórica 2009–2018 e foram analisadas as variáveis: faixa etária, raça e escolaridade. Para organização dos dados foi utilizado o Microsoft® Excel. Resultados: Observou-se um crescente constante nas taxas de detecção de sífilis em gestante, o que atribui não somente a multiplicação do número de casos, mas também ao aumento nos registros da vigilância epidemiológica. Evidenciou-se que mulheres pardas com baixo grau de escolaridade estão mais susceptíveis a contaminação pelo Treponema pallidum. Conclusão: A taxa de detecção vem aumentando progressivamente a cada ano, tornando necessária a adoção de medidas de educação em saúde e garantia adequada da assistência no que tange a testagem e tratamento da sífilis, visando a redução dos casos notificáveis e consequentemente a contaminação de gestantes e transmissão vertical.

Analysis of the phenotypic adaptability and stability of strains of cowpea through the GGE Biplot approach

The cowpea is produced in different environmental conditions in several regions of Brazil. It is crucial to select and develop cultivars that attend to the regional requirements with high productivity, adaptability, and stability, due to the interaction between the genotype and the environment. This research aimed to select strains of cowpea for the simultaneous presence of high genotypic productivity, adaptability, and stability in the North-eastern region of the state of Rio de Janeiro (Brazil) by the GGE-Biplot method. The study assessed 27 genotypes: 23 strains and four cultivars, in six environments of the North-eastern region of the state of Rio de Janeiro, during the years 2016, 2017, and 2018. The experimental design was a randomized block design with four repetitions. The GGE-Biplpot method assessed the genotypic adaptability and stability, by the use of the statistical software R. The interaction between the environment and the genotypes was complex, and the general average for the productivity of the grains was 1231.98 kg/ha. GGE-Biplot method was efficient in identifying the best strains to be suggested for the use in the North-eastern region of the state of Rio de Janeiro. The strains (9), (3), and (6) were classified as ideotypes due to their superior performance compared to the general average, and their stability. Their performance overcame the control cultivars BRS Tumucumaque, BRS Imponente, BRS-Itaim e CB-27.

O ensino de ciências na EJA e a aplicação de uma proposta de metodologia ativa

O Ensino de Ciências em turmas de Educação de Jovens e Adultos(EJA) tem em geral uma realidade muito diversa em relação às outras turmas em razão da significativa adversidade de contexto sociocultural dos alunos em relação aos objetos de ensino, diante da perspectiva de quem ensina e de quem aprende. O objetivo desse trabalho foi aplicar uma proposta de metodologia ativa, em uma turma de EJA de um colégio de um município do estado do Rio de Janeiro. Este trabalho traz uma contribuição à melhoria do ensino e aprendizagem na EJA, além de promover a participação dos alunos nesse processo, a partir da pesquisa realizada por um professor sobre a adoção de uma metodologia que se aproxima da concepção de Dewey de aplicação de métodos ativos de “aprender fazendo”. O cenário da pesquisa foi a sala de aula de uma turma do 90 ano do Colégio. O percurso metodológico foi constituído das seguintes etapas: planejamento das aulas, as sequências didáticas, as ferramentas didáticas; execução da proposta metodológica; metodologia de avaliação da aprendizagem. Os resultados obtidos sinalizaram uma prática docente que permitiu a propensão dos alunos a ação, de forma a vivenciarem o que estava sendo ensinado possibilitando dessa forma uma melhoria da aprendizagem.
