A formação científica brasileira e o PISA 2006

Este trabalho investigou a formação científica brasileira a partir dos dados do PISA 2006. O PISA - Programa Internacional de Avaliação dos Estudantes - é um programa internacional de avaliação comparada, aplicado a uma amostra de estudantes de 15 anos de idade. O ensino adequado de ciências estimula o raciocínio lógico e a curiosidade, ajuda a formar cidadãos mais aptos a enfrentar os desafios da sociedade contemporânea e fortalece a democracia, dando à população, em geral, melhores condições para participar dos debates cada vez mais comuns sobre temas científicos que afetam nosso cotidiano. Partindo da importância e pertinência de se discutir a formação científica brasileira e fazendo uso dos dados do PISA 2006, buscou-se responder a três questões: (a) qual a percepção dos alunos brasileiros que participaram do PISA 2006 sobre Ciências? (b) como o Brasil se situa no contexto internacional no que se refere às competências científicas priorizadas por esta avaliação? (c) que características dos estudantes estão associadas aos seus resultados no teste de Ciências aplicado pelo PISA 2006? Para a realização do estudo, conduzimos nossas análises baseando-nos em duas lógicas principais: descrição (estatística univariada e bivariada) e explicação (teste de modelos de regressão linear). Os resultados indicam que os alunos brasileiros tem relativo interesse pela Ciência, no entanto apresentam uma visão bastante estereotipada e demonstram não associá-la a si. Aparentemente, a ciência tem relação com fenômenos que estão muito além da compreensão e configura-se em algo abstrato que não está diretamente ligado aos alunos brasileiros. Estes apontam a escola como principal fonte de aprendizagem de tópicos relacionados a Ciência, porém, a escola parece não converter o potencial interesse dos alunos por Ciências em letramento científico. O Brasil ocupa a 52 posição entre os 57 países participantes e está alocado no nível mais baixo de desempenho do PISA 2006. Entre os principais aspectos que impactam significativamente os resultados dos alunos brasileiros no programa estão a Rede de Ensino, o Atraso Escolar, o Nível Socioeconômico e o Nível de Escolaridade dos Pais.

Le redoublement, la réussite scolaire et l’objectif de la Scolarisation Primaire Universelle (SPU) d’ici à 2015 dans le cadre de l’Éducation Pour Tous (EPT) : cas du Sénégal à partir des données longitudinales du PASEC

L’Éducation Pour Tous mobilise la communauté internationale et les gouvernements depuis 1990. Cet engagement global renouvelé en 2000 sous l’auspice de l’UNESCO puis des Nations-Unies, porte notamment sur un objectif de base : l’universalisation de la scolarisation primaire complète pour tous les enfants d’âge scolaire à l’horizon de 2015. Plusieurs études sur la réalisation de cet objectif montrent que les pays en développement sont les plus à risque et que les progrès accomplis dans la plupart de ces pays, pourraient être plus importants si la pratique du redoublement faisait davantage l’objet de régulation et de contrôle. Cela contribuerait à améliorer la réussite scolaire et accroître la rétention des élèves au sein des systèmes éducatifs. La pratique du redoublement est en effet une tradition dans plusieurs systèmes éducatifs. Elle est particulièrement prépondérante dans certains groupes de pays ou régions, notamment en Afrique francophone au sud du Sahara. Dans ces pays, le PASEC - Programme d’Analyse des Systèmes Éducatifs de la CONFEMEN (Conférence des Ministres de l’Éducation Nationale des pays ayant le français en partage) - œuvre à améliorer l’accès à une éducation de qualité pour tous, par exemple, en informant les politiques sur la situation nationale du redoublement. Cette recherche sur le redoublement, la réussite scolaire et l’objectif de la Scolarisation Primaire Universelle (SPU) privilégie la dimension pédagogique, l’analyse empirique et étudie le cas du Sénégal. Elle présente et discute les indicateurs internationaux de suivi de l’objectif de la SPU, fait le point de l’état des connaissances sur le redoublement et la réussite scolaire et montre le défi que représente la réalisation de l’objectif de la SPU notamment dans les pays francophones d’Afrique sub-Saharienne. Exploitant les données existantes de l’enquête longitudinale de suivi de cohorte du PASEC au Sénégal entre 1995 et 2000, cette recherche examine le parcours scolaire des élèves en vue de la réalisation de l’objectif de la SPU. L’examen effectué combine des approches d’analyse transversale et longitudinale du redoublement et des apprentissages par rapport aux caractéristiques personnelles, familiales et scolaires de l’élève. Les résultats d’analyse montrent des variabilités, notamment par rapport aux caractéristiques personnelles de l’élève et à celles de sa classe et de son milieu de scolarisation. L’analyse longitudinale du redoublement s’est appuyée sur le diagramme de flux scolaire et a permis de produire un ensemble d’indicateurs d’efficacité interne du système éducatif du Sénégal. Pour la cohorte étudiée, du fait de l’importance des redoublements et des abandons scolaires, il faut en moyenne 9,4 années de scolarité pour que l’élève progresse du deuxième au sixième (dernier) grade du primaire. Seulement 39% de l’effectif de la cohorte survivent au dernier grade ce qui suggère que si cette tendance se maintenait, le Sénégal serait à risque de ne pas réaliser l’objectif de la SPU. Une évaluation de la situation courante à partir de données plus récentes serait requise. Le diagramme de flux scolaire constitue un outil de planification de l’éducation et représente de ce fait un important levier aux mains des autorités politiques pour agir sur les paramètres du système éducatif (paramètres liés à la qualité de l’éducation, à l’efficacité interne, etc.) afin de répondre à des objectifs spécifiques ou d’étapes pouvant conduire, par exemple, à la réalisation de l’objectif de la SPU.

Fracasso escolar e autoconceito

O principal objetivo deste estudo foi investigar a possível relação entre o fracasso escolar, entendido como anos de repetência, e o autoconceito de alunos da 8a. série do 1º grau da rede oficial de escolas de Campo Grande, no Município do Rio de Janeiro. Este trabalho foi realizado com dois grupos de alunos, sendo que um grupo havia tido experiência de fracasso escolar, isto é, repetência, e o outro grupo não. Para verificar a relação, repetência e autoconceito, foi utilizada a "Escala de Autoconceito Tennessee", desenvolvida por H. Fitts, traduzida e reduzida por Corona em 1977. A escala consta de 30 itens com 5 alternativas de respostas para cada item (tipo Likertl, sua amplitude é de 150 pontos, sendo o maior escore possível 150 (30x51 o menor 30 (30x1), indicando respectivamente uma desestruturação do autoconceito em termos de supervalorização e uma desestruturação por infra-aloração. O confronto das médias de autoconceito de grupos de alunos com diferentes frequências de repetência e sem repetência mostrou que a repetência de serie covaria significativamente com o autoconceito dos alunos estudados, concomitantemente, com a classe social. Apesar de os resultados do estudo não serem conclusivos, ainda assim consideramos válida sua realização, na medida em que fornece mais esclarecimentos a um dos mais graves problemas da escola de 1º grau no Brasil, que é o da repetência.

Viel bringt viel? Effekte lernzeitverlängernder Maßnahmen auf die Lese- und Mathematikleistungen von Grundschülerinnen und Grundschülern mit ungünstiger Lernausgangslage

Der vorliegende Beitrag untersucht die Effekte von lernzeitverlängernden Maßnahmen für Grundschülerinnen und Grundschüler in Mecklenburg-Vorpommern mit einer ungünstigen Lernausgangslage zum Zeitpunkt der Einschulung. Dazu wurde über die gesamte Grundschulzeit hinweg die Leistungsentwicklung von 67 Kindern in den Bereichen Lesen und Rechnen erfasst. Bei 19 Kindern wurde eine Lernzeitverlängerung durch Diagnoseförderklassen (DFK) realisiert, bei 18 durch eine Klassenwiederholung (KW) und 30 Kinder lernten in regulären Grundschulklassen (GSK) ohne eine Lernzeitverlängerung. Die Auswertungen der Daten mittels Hierarchisch-linearer Modelle (HLM) weisen auf gleiche Entwicklungsverläufe der drei Untersuchungsgruppen in den Bereichen Lesen und Mathematik hin. Zum Ende der Klasse 4 erreichten die drei Gruppen ähnliche Leistungsniveaus. In allen drei Settings fiel auf, dass die Entwicklung mathematischer Kompetenzen über die Schulzeit hinweg verzögert erfolgte. Ungünstige Lernausgangslagen im Bereich Mathematik konnten den Analysen zufolge durch keine der untersuchten Beschulungsformen ausreichend kompensiert werden. (DIPF/Orig.)

Microeconomic instability and children's human capital accumulation: the effects of idiosyncratic shocks to father's income on child labor, school drop-outs and repetition rates in Brazil

This paper evaluates the long-run effects of economic instability. In particular, we study the impact of idiosyncratic shocks to father’s income on children’s human capital accumulation variables such as school drop-outs, repetition rates and domestic and non-domestic labor. Although, the problem of child labor in Brazil has declined greatly during the last decade, the number of children working is still substantial. The low levels of educational attainment in Brazil are also a main cause for concern. The large rotating panel data set used allows for the estimation of the impacts of changes in occupational and income status of fathers on changes in his child’s time allocation circumstances. The empirical analysis is restricted to families with fathers, mothers and at least one child between 10 and 15 years of age in the main Brazilian metropolitan areas during the 1982-1999 period. We perform logistic regressions controlling for child characteristics (gender, age, if he/she is behind in school for age), parents characteristics (grade attainment and income) and time and location variables. The main variables analyzed are dynamic proxies of impulses and responses, namely: shocks to household head’s income and unemployment status, on the one hand and child’s probability of dropping out of school, of repeating a grade and of start working, on the other. The findings suggest that father’s income has a significant positive correlation with child’s dropping out of school and of repeating a grade. The findings do not suggest a significant relationship between a father’s becoming unemployed and a child entering the non-domestic labor market. However, the results demonstrate a significant positive relationship between a father becoming unemployed and a child beginning to work in domestic labor. There was also a positive correlation between father becoming unemployed and a child dropping out and repeating a grade. Both gender and age were highly significant with boys and older children being more likely to work, drop-out and repeat grades.

Errors in nonword repetition: bridging short- and long-term memory

According to the working memory model, the phonological loop is the component of working memory specialized in processing and manipulating limited amounts of speech-based information. The Children's Test of Nonword Repetition (CNRep) is a suitable measure of phonological short-term memory for English-speaking children, which was validated by the Brazilian Children's Test of Pseudoword Repetition (BCPR) as a Portuguese-language version. The objectives of the present study were: i) to investigate developmental aspects of the phonological memory processing by error analysis in the nonword repetition task, and ii) to examine phoneme (substitution, omission and addition) and order (migration) errors made in the BCPR by 180 normal Brazilian children of both sexes aged 4-10, from preschool to 4th grade. The dominant error was substitution [F(3,525) = 180.47; P < 0.0001]. The performance was age-related [F(4,175) = 14.53; P < 0.0001]. The length effect, i.e., more errors in long than in short items, was observed [F(3,519) = 108.36; P < 0.0001]. In 5-syllable pseudowords, errors occurred mainly in the middle of the stimuli, before the syllabic stress [F(4,16) = 6.03; P = 0.003]; substitutions appeared more at the end of the stimuli, after the stress [F(12,48) = 2.27; P = 0.02]. In conclusion, the BCPR error analysis supports the idea that phonological loop capacity is relatively constant during development, although school learning increases the efficiency of this system. Moreover, there are indications that long-term memory contributes to holding memory trace. The findings were discussed in terms of distinctiveness, clustering and redintegration hypotheses.

The place of writing in first grade Kuwaiti english education : a sociological case study

A hybridized society, Kuwait meshes Islamic ideologies with western culture. Linguistically, English exists across both foreign language and second language nomenclatures in the country due to globalization and internationalization which has seen increasing use of English in Kuwait. Originally consisting of listening, speaking, reading and writing, the first grade English curriculum in Kuwait was narrowed in 2002 to focus only on the development of oral English skills, and to exclude writing. Since that time, both Kuwaiti teachers and parents have expressed dissatisfaction with this curriculum on the basis that this model disadvantages their children. In first grade however, the teaching of pre-writing has remained as part of the curriculum. This research analyses the parameters of English pre-writing and writing instruction in first grade in Kuwaiti classrooms, investigates first grade English pre-writing and writing teaching, and gathers insights from parents, teachers and students regarding the appropriateness of the current curriculum. Through interviews and classroom observations, and an analysis of curriculum documents, this case study found that the relationship between oral and written language is more complex than suggested by either the Kuwaiti curriculum reform, or international literature concerning the delayed teaching of writing. Intended curriculum integration across Kuwait subjects is also far more complex than first believed, due to a developmental mismatch between English pre-writing skills and Arabic language capabilities. Findings suggest an alternative approach to teaching writing may be more appropriate and more effective for first Grade students in the current Kuwait curriculum context. They contribute also to an emerging interest in the second and foreign language fields in the teaching of writing to young learners.

Gender and grade differences in upper elementary school children’s descriptive and evaluative self-statements and self-esteem

Gender and developmental differences in self-description, self-evaluation and self-esteem were investigated using 957 elementary school children in grades 3 to 7. Gender differences were found for six of the seven descriptive statements and for five of the seven evaluative statements. The major gender stereotypical findings from previous studies were replicated. Boys reported higher scores than girls on descriptive and evaluative statements about their physical abilities and mathematics, while girls reported higher scores on descriptive and evaluative statements about reading. Declines over time were noted for all self-evaluations except having good relations with peers and for global self-esteem, providing some support for the notion that the decline in self-concepts and self-esteem may be attributed to the children's perceptions of themselves becoming more accurate and less egocentric in line with their cognitive capacity to integrate external feedback realistically.

In vitro and in vivo analysis of co-electrospun scaffolds made of medical grade poly(epsilon-caprolactone) and porcine collagen

In this study, a nanofiber mesh made by co-electrospinning medical grade poly(epsilon-caprolactone) and collagen (mPCL/Col) was fabricated and studied. Its mechanical properties and characteristics were analyzed and compared to mPCL meshes. mPCL/Col meshes showed a reduction in strength but an increase in ductility when compared to PCL meshes. In vitro assays revealed that mPCL/Col supported the attachment and proliferation of smooth muscle cells on both sides of the mesh. In vivo studies in the corpus cavernosa of rabbits revealed that the mPCL/Col scaffold used in conjunction with autologous smooth muscle cells resulted in better integration with host tissue when compared to cell free scaffolds. On a cellular level preseeded scaffolds showed a minimized foreign body reaction.
