Os limites e as possibilidades de uma sequência didática: o conceito de proporcionalidade e a aprendizagem de alunos do 5º ano do Ensino Fundamental

This study aimed to analyze the limits and possibilities of a didactic sequence, addressing the concept of proportionality in the learning of students in 5th year of elementary school. From the results of the Diagnostic Assessment Initial applied to students in a class of 5th grade of elementary school, we selected eight (8) students who participated in the constituent activities of that instructional sequence. For the development of this sequence were used theoretical elements of Genetic Epistemology (Piaget, 1990), the theory of fields of Conceptual Vergnaud (1996) and the definition of instructional sequence proposed by Zabala (1998). Finally, after 20 days of application of these activities, we applied the Diagnostic Assessment Final aimed at investigating which concepts related to proportionality were built by the participating students. By analyzing the collected data, it can be concluded the following about the possibilities of teaching sequence: 1) students who, in Diagnostica Home Assessment used the multiplication algorithm, but also did not indicate the comparison between quantities are now performing; 2) students who, in the Diagnostic Assessment Initial, used the addition algorithm, now gradually are using the multiplication algorithm; 3)students who, in the Diagnostic Assessment Initial, could not solve problems involving the idea of proportionality, are now resolving, however, still use, in large part, the addition operation as a strategy for this proportional thinking. Now, in relation to the limits of the sequence noted: 1)time sufficient to propose a higher number of problem conditions to be carried by students who may have been a trigger of construction have not through the proportional multiplication;2)the distant proposition situations of assimilation schemes (interpretation) of the students, which may have caused certain imbalance in them, preventing them from thinking about the problem situation;3)the rapid passage of...

Formação docente e o ensino da educação física junto às crianças com 6 anos de idade no 1º ano do ensino fundamental: a perspectiva dos professores de educação física

Since there are few physical education teachers working in kindergarten, now, due to the elementary school for nine years - getting children 6 years of age, this seems to be a challenge for teachers. Therefore, interested in mobilizing efforts to understand how your training is on this new context, and how is this entry of students from 6 years old in elementary school. From the perspective of the physical education teacher who is acting in this context. In this sense, the objective of this study was to analyze teacher training and teaching of physical education among children 6 years of age entering the first grade of elementary school from the perspective of physical education teachers who work in this field. This study was guided by the principles of qualitative research, making the collection through semi-structured interview, 11 participated in the investigation of physical education teachers working in the first grade of elementary school. The categories of analysis that have emerged from our study were: 1 Teacher training; 2 The 9-year elementary school for children 6 years of age; 3 Teaching physical education in early childhood education: Reflections on its limits and its possibilities. We can point out that physical education in school is still recognized as unimportant, although the LDB 9394/96 art. 26 § 3, have given your requirement, this is not enough to change the scenario that presents itself. School is still considered by many as a space in which the body is separated from the cognitive. Therefore, for many, the play of children is worthless and physical education is worthless. Teachers interviewed here reveal that has focused efforts on making a better quality of physical education, especially among children 1 year, trying to meet their expectations and need characteristics of the universe of childhood

Distribuição geográfica de agravos nutricionais entre escolares na cidade de Piracicaba-SP, Brasil

The objective was to map the prevalence of nutritional disorders in children attending the 1st to 4th grade of 12 public elementary schools located in the 5 administrative regions of Piracicaba, SP, each with its own socioeconomic profi le, from 2003 to 2006. A total of 16,068 children, divided into 8,133 (50.6%) girls and 7,935 (49.4%) boys, aged 7 to 11 years, were weighed and measured. Their nutritional status indicators heightfor-age (H/A), weight-for-age (W/A), and body mass index-for-age (BMI/A) were compared with those of the NCHS/CDC 2000 reference population and classifi ed according to the z-score cut-off points recommended by the World Health Organization. During that period, the Western Region, which has the lowest socioeconomic indicators, had the lowest z-score medians of the three anthropometric indicators assessed (p<0.0001) and was the only region to have a higher-than-expected stunting prevalence (3.0% with Z < -2). Excess weight prevalence was higher than expected in all regions. The Central Region, which has the highest socioeconomic indicators, had the highest excess weight prevalence (6.0% with Z > 2). Time had a positive effect on the stunted children, reducing the stunting rates in the regions with the lowest socioeconomic indicators. In conclusion, the three nutritional status indicators showed results suitable to the social and economic characteristics of each region. Although nutritional disorders have particular characteristics, they are a problem to the entire population.

El crescimiento poblacional: una propuesta pedagógica para abordar biologia, matemáticas y TICs

In this paper we propose the achievement of an interdisciplinary activity evolving biology and mathematics knowledge with students of the third grade of high school about the population growth theme. The goal of this activity is to offer to the students a wider perception about the ways of population growth of different organisms from their home region, helping them to represent it through mathematics models. The formulation of the research problem is done from the theoretical and empirical data and the student is encouraged to behave in a participative and dialogic way in all stages of the activity. The mathematical modeling and the graphic representation of the population growth are made through the mathematical software Geogebra and we emphasize the qualitative analysis of the data from the biological and environmental education point of view.
