RESUMO: Este artigo discute aspectos da seleção e legitimação de gêneros do discurso tomados como objeto de ensino na implementação de projetos didáticos de língua portuguesa, com base em duas entrevistas semiestruturadas com bolsistas de iniciação à docência do Programa Institucional de Bolsas de Iniciação à Docência (PIBID) em Letras da Universidade Estadual de Campinas (UNICAMP). O intuito é gerar conhecimento situado acerca das práticas e dos saberes docentes no contexto do PIBID, a fim de problematizar as escolhas e apreciações feitas, à luz das demandas da formação universitária, que mobiliza princípios teóricos e pedagógicos específicos, e da escola, que tem suas próprias necessidades.

ABSTRACT: This article discusses aspects of the selection and legitimation of discourse genres, which are understood as teaching objects, in the implementation of Portuguese Language didactic projects. The corpus is comprised of two semi-structured interviews with undergraduate scholarship recipients of the Institutional Program of Initiation Teaching Scholarship (PIBID) - Language Arts at University of Campinas (UNICAMP). The aim is to generate knowledge about the teaching practices in the context of PIBID, in order to problematize the choices and appreciations made, in light of the demands of university education, which mobilize specific theoretical and pedagogical principles, and school education, with its own demands.

RESUMO O feijão-caupi é uma leguminosa com ampla plasticidade, versatilidade e potencial nutritivo. Trata-se de uma espécie bastante utilizada como fonte de renda e subsistência para pequenos agricultores em vários estados brasileiros, entre estes, o do Acre. Devido as diferentes variedades encontradas no Estado, é alvo de estudos visando o seu melhoramento genético. Assim, como uma das primeiras etapas do seu melhoramento, objetivou-se determinar a importância e correlações de caracteres para a diversidade e seleção em variedades tradicionais de feijão-caupi. O experimento foi realizado em delineamento inteiramente casualizado, com parcelas constituídas por quatro vasos de volume igual a 15,7 L, com uma planta cada e duas repetições. As características avaliadas foram: dias para emergência, florescimento (dias), vigor da planta (nota), número de nós do caule principal, comprimento do folíolo apical (mm), largura do folíolo apical (mm), comprimento da vagem (cm) e largura da vagem (cm). Foram obtidos os coeficientes de correlações (fenotípicas, genotípicas e ambientais), realizada a análise de componentes principais e a importância dos caracteres pelo método proposto por Singh. O método de Singh e componentes principais foram parcialmente concordantes na distinção dos caracteres avaliados. Os caracteres dias para a emergência, largura do folíolo apical, florescimento e comprimento do folíolo apical foram os principais determinantes para quantificação dos genótipos, e os que mais contribuíram significativamente para a variabilidade de feijão-caupi. A característica menos discriminante pela análise de componentes principais e recomendada para descarte foi o vigor da planta.

ABSTRACT Cowpea is a legume with ample plasticity, versatility and nutritional potential. It is a species widely used as a source of income and subsistence for small farmers in several Brazilian states, among them Acre. Due to the different varieties found in the State, it is the target of studies aiming at its genetic improvement. Thus, as one of the first stages of its improvement, it was aimed to determine the importance and correlations of characters for diversity and selection in traditional varieties of cowpea. The experiment was carried in completely randomized design, with plots consisting of four vase with capacity to 15.7 L, with one plant each and two replicates. The characteristics evaluated were: days for emergence, flowering (days), plant vigor (note), number of main stem nodes, apical leaflet length (mm), apical leaflet width (mm), length of pod (cm) and width of the pod (cm). The correlation coefficients (phenotypic, genotypic and environmental) were obtained, and the principal components analysis and the importance of the characters by the method proposed by Singh were carried out. The Singh method and principal components analysis were partially concordant in the distinction of the evaluated characters. The days for emergence, width of the apical leaflet, flowering and length of the apical leaflet were the main determinants for quantification of the genotypes and those that contributed the most to the variability of cowpea. The least discriminant characteristic by principal component analysis and recommended for discarding was plant vigor.

The objective of this study was to evaluate the genetic divergence of forage peanut in relation to agronomic and chemical traits in both rainy and dry seasons. This experiment was conducted with genotypes from the Forage Peanut Active Germoplasm Bank located in Embrapa Acre. Eighteen genotypes of forage peanut were used: 12 genotypes of A. pintoi, four genotypes of the A. repens species and two interspecific hybrids of A. pintoi × A. repens. The design was of randomized blocks with five replicates. All traits were submitted to analyses of variance and later, study of genetic divergence was done through multivariate analysis techniques, in which the Tocher's optimization method and the nearest neighbor method were used. Dissimilarity measure used in cluster analysis was the generalized distance of Mahalanobis. No pattern was found in the cluster based on species used, according to the results. There is genetic variability for all traits except neutral detergent fiber, acid detergent fiber, hemicellulose and lignin in the rainy season and for pests in the dry season. The traits which presented most relative contribution in the study of genetic divergence of forage peanut were flowering, dry matter yield and average height in the rainy season and crude protein and average height in the dry season. The established cluster may help the breeder to choose parents and crossings to be selected in forage peanut breeding programs.

Os sistemas de avaliação desenvolvidos na última década mantêm um mesmo objetivo prioritário: encontrar mecanismos para melhorar a qualidade do ensino oferecido à sociedade de forma eficaz e eficiente. Além de identificar resultados da aprendizagem dos alunos, avalia-se o conjunto do sistema educacional. Dentro desse contexto o Sistema Mineiro de Avaliação da Educação Pública (SIMAVE) foi instituído pela Secretaria de Estado de Educação no ano de 2000. O presente estudo empregou modelos hierárquicos (multinível) com o objetivo de identificar a relação entre o desempenho escolar, as características técnico-pedagógicas das escolas e o perfil sócio-econômico dos alunos das 4ª séries do Ensino Fundamental que fizeram os testes do SIMAVE-2000. Buscando investigar os fatores que atuam na diferenciação entre as turmas dentro das escolas foram considerados os modelos com os níveis de hierarquia: turma (nível 1) e escola (nível 2). Foi encontrada explicação para uma grande proporção da variação dos escores entre as turmas.

The evaluation systems developed on the last decade keep a same main objective: to find ways to efficiently improve the quality of the education. Besides identifying results of the pupil's learning, the educational system is also evaluated. In this context, the Sistema Mineiro de Avaliação da Educação Pública (SIMAVE) was instituted in 2000 year by the Secretaria de Estado de Educação. The present study had used multilevel models with the objective to identify the relation between the educational performance, the technic-pedagogical characteristics of the schools and the social-economic profile of the 4th. grade pupils that had made SIMAVE-2000 tests. Searching to investigate the factors that act in the classrooms differentiation in schools had been considered the multilevel models with the hierarchy levels: classroom (level 1) and school (level 2). It was found explanation for a great proportion of the variation of the scores of the classroom.
