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...

Un passo indietro al Decameron e os limites intangíveis do Novellino

The narratives of Decameron, composed by Giovanni Boccacio in the 14th century, possess a popular content carefully tied together by a formal structure capable of concentrating sophisticated techniques. The present paper revisits some relation possibilities between Decameron and Novellino, an anonymous work from the 13th century, composed on the basis of fables and stories gathered mainly from the oral tradition. Our aim is not to demonstrate a genealogy of the prose and of its freedom to recover narrative situations but to reflect, by means of examples of great reverberation, on the strategies developed to make elements from the ancient tradition highly functional in the literary tradition, according to the formal resources available in each period.

Os limites do corpo: modificações corporais

El cuerpo presenta rastros de la historia y cultura de las sociedades por toda la historia de la humanidad. El presente estudio quiere, através de pesquisas sobre el cuerpo, entender como las modificaiones corporales han acompañado la historia del hombre, de las tribus antiguas hasta la atualidad y como son hoy los procedimientos de cambiar la forma física. Através de trabajo de campo conocer profisionales que hacen algunos tipos de modificaciones corporales y gente que las tienen en sus cuerpos, entender las razones para que cambien sus cuerpos permanentemente - en la mayoria de los casos - y como la idea de individualidad surge cuando se hace una marca personal en el cuerpo. Además, compreender el porque esas prácticas se están convirtiendo cada vez mas común en nuestra sociedade actual

Jogo de handebol e futsal na escola: possibilidades e limites pedagógicos

Sports team, specifically soccer and handball, has traditionally composing the physical education school contents as a curriculum component. There are several criticisms to extend this approach beyond the sportive discourse. While we recognize this need for expansion, we believe that the methodological endeavors to teach these sports content are still very poor, requiring, therefore, studies that guide us in changing not only contents but also the way of teaching it, which implies new e teaching, pupils and teaching relationship perspective. In this sense, the objective of this study was to identify and analyze, from a sports team tactics teaching approaches of invasion, the demonstrations by students, the phases of handball and soccer games, as well as the elements/dynamic structural, functional and operational in the same school environment. Given this objective, qualitative research, specifically, collaborative action research, best meets investigation is this scenario, since classroom teacher and students also participated in the content construction and strategies undertaken during the intervention. The study enrolled 28 students in the fifth grade, aging 10 to 11 years, in a Bauru/SP public school, physical education teacher and the researcher. Were planned and taught together, 14 classes over a semester with the handball and futsal content, guided for teaching tactics approaches. The data collections were made through systematic lessons observation (through filming and recording diary), interviews with students and descriptive reports made by the classroom teacher and researcher. The results indicate that there was an improvement in the phases of soccer and handball game, even though only the latter has changed its category phase to decentralized anarchic phase. Several students showed in the situational interviews, a more elaborate game understanding than the one identified in the game demonstration. In the analysis of relationship levels..

Estado e burocracia: limites de aplicação da Lei de Acesso a Informações no Brasil

Saudada como consequência de um complexo processo de evolução do arcabouço jurídico-institucional brasileiro, a Lei Federal 12.527, denominada Lei de Acesso a Informações, sancionada em 18 de novembro de 2011 e regulamentada no âmbito do Poder Executivo federal pelo Decreto 7.724, de 16 de maio de 2012, atende o pressuposto do direito à informação fixado pela Constituição Federal de 1988. Valores e práticas historicamente construídos podem significar obstáculos e resistências importantes à sua aplicação. Características do próprio texto legal, que vêm à tona quando comparado aos seus congêneres internacionais, também sinalizam possíveis complicadores. Este artigo indica limites que a Lei de Acesso a Informações pode enfrentar à sua consolidação, originários principalmente do campo da cultura político-institucional, que se tornam mais nítidos com o exame de características brasileiras em comparação com outros países que possuem dispositivos semelhantes.

A resolução de problemas no contexto do estágio curricular supervisionado: dificuldades e limites de licenciandos em matemática

The aim was to investigate the difficulties and limits of four future mathematics teachers to conduct classes in regencies approach of problem solving. Based on participation in a course this approach, undergraduates elaborated three didactic sequences, which were taught by the activity of conducting classroom discipline Supervised Curricular Training. After this work, participated in an individual interview to report what had developed in classroom. The results showed difficulties in the following aspects: in the elaboration of didactic sequences; in providing an environment for discussion of resolution strategies students. Furthermore, the data analysis showed limits related: the lack of space at the school teacher to allow implementation of lessons developed; lack of basic mathematical knowledge of the students.

As dificuldades para a gestão do PIBID a partir do olhar de coordenadores e colaboradores em subprojetos na Faculdade de Ciências Bauru: limites e possibilidades

The Institutional Program of Initiation to Teaching, the PIBID, has by its nature the training of teachers. Focused on graduate students, the PIBID acts as a proposal for training beyond the mandatory classes, giving to the students that are entering the program, a great opportunity to improve their training as a teacher. Thus, this work focuses on a discussion of the PIBID at the Faculty of Sciences UNESP Bauru, aimed at subprojects of graduate students linked to the areas of Natural Sciences, Mathematics, Physics, Biology and Chemistry, working in an interdisciplinary way. I interviewed five teachers (three area coordinators and two contributors) seeking to verify, in their view, the understanding about the program and what were the major difficulties in the training of teachers. For contributors teachers and coordinators of the subprojects, interdisciplinarity has a very important role in the training of new teachers, and the PIBID allows to work this concept more broadly than just in the mandatory classes. However, a program so big like the PIBID comes with problems and it is in this context that this study was conducted. Coordinator teachers and contributors of the subprojects identified flaws in the program that may affect the activities proposed in the institutional design
