Cultura pedagógica e formação de professores: a biblioteca da escola normal de Piracicaba (1911-1920)

Cet article a pour objet la Bibliothèque de l'École Normale de Piracicaba, à l'intérieur de São Paulo, entre les années 1911 et 1920, parce qu'elle représente un lieu de formation d'enseignants et organisation de culture pédagogique. Cette Bibliothèque qui a été constituée au long du cycle de vie de l'École Complémentaire de Piracicaba (1896-1911) et officialisée à partir de 1911 aura le rôle d'organiser et disséminer une certaine culture pédagogique en raison de sélectionner, trier et distribuer un ensemble de connaissances propres à la profession enseignante. Elle symbolise un espace de formation de l'enseignant de l'École Normale et de l'élève-lecteur. L'étude de la culture pédagogique se concentre sur l'analyse de cette bibliothèque.

Lexicografia pedagógica: atores e interfaces

Os dicionários para aprendizes de línguas estrangeiras são obras relativamente recentes no mercado editorial e atendem uma demanda por obras pedagógicas que foi ignorada pelos lexicógrafos durante muito tempo. Esse segmento do mercado lexicográfico vem se revelando promissor, com diversas possibilidades de inovações. A fim de delinear o campo de desenvolvimento da Lexicografia Pedagógica, este artigo analisa-a sob duas perspectivas: a de suas interfaces com outras áreas da Lingüística e a de seus atores, pessoas cuja atuação influencia a produção de suas obras. Esta exposição tem o objetivo de despertar o interesse de pesquisadores brasileiros pela Lexicografia Pedagógica e, indiretamente, promover a produção nacional de dicionários pedagógicos.

Estimación de la heredabilidad del intervalo de partos en bovinos cruzados

Objetive. To estimate the heritability of interval calving in crossbred cattle. Materials and methods. Information from database of La Leyenda farm, in the municipality of Caucasia (Antioquia) was used. A single-trait animal model was used, that included genetic group, year of birth, season of birth and the number of calvings as fixed effects and the additive direct genetic, permanent environmental and residual as random effects. Results. The heritability estimated was 0.15 +/- 0.07 and the phenotypic mean was 544 +/- 97 days. Conclusions. The heritability for the interval between calvings was low, indicating that little genetic progress can be achieved by selecting for this characteristic.

O intuitivo e o lógico no conhecimento matemático: análise de uma proposta pedagógica em relação a abordagens filosóficas atuais e ao contexto educacional da matemática

In this paper, we consider Meneghetti & Bicudo's proposal (2003) regarding the constitution of mathematical knowledge and analyze it with respect to the following two focuses: in relation to conceptions of mathematical knowledge following the fundamentalist crisis in mathematics; and in the educational context of mathematics. The investigation of the first focus is done analyzing new claims in mathematical philosophy. The investigation of the second focus is done firstly via a theoretical reflection followed by an examination of the implementation of the proposal in the process of development of didactic materials for teaching and learning Mathematics. Finally, we present the main results of the application of one of those materials.

Estimación de parámetros genéticos para la producción de leche en el día del control empleando un modelo de regresión aleatoria para primeras lactancias en búfalos de la costa norte de Colombia

A total of 5575 monthly test-day yield records from 796 lactations buffaloes first in the north coast of Colombia. The model included random direct additive genetic and permanent environment effects. As fixed effects were included, contemporary groups, and age of cow at calving as covaraible, linear and quadratic effects. Test-day (PLDC) yield was 3.89 ± 1.14 kg. The PLDC ranged from 2.86 kg to 4.26 kg while the highest values towards the middle of lactation. The heritability estimates obtained for PLDC ranged from 0.23 to 0.47. Genetic correlations between PLDC, declining steadily increased the distance between PLDC. Phenotypic variances were higher in the initial PLDC and decreasing towards the end of lactation. The results found in this study indicate that there is a high genetic variability for the PLDC in the population studied using a random regression model.
