25. O aluno do ensino médio e a criação de uma fórmula para o termo geral da progressão aritmética
This work presents a qualitative research which is guided by the objective of investigating whether if its possible to create conditions so that High School students generalise terms of arithmetic progressions and, if so, whether this generalization allows students to build a formula of general term of this type of sequence. The relevance of this research is

27. Construção do termo geral da progressão aritmética pela observação e generalização de padrões
Today it has been disclosed the poor performance of High School students in learning the Algebra. On the other hand, the results of researches, such as Vale e Pimentel (2005) and Machado (2006) among others, emphasized the importance of working with the observation and generalization of patterns to develop the algebraic thinking, which can help to overcome t

28. Os alunos de 5 série/6 ano frente a atividades sobre abservação e generalização de padrões
This work reports a research which aim was to investigate whether and how 5th series/ 6th year of elementary school students are sensitized by and create strategies to solve situations involving the perception and generalization of patterns. Mason (1996), Vale &Pimentel (2005), Radford, Bardini &Sabena (2007) and Machado (2006) works gave the main base for t

29. O uso de vários registros na resolução de inequações: uma abordagem funcional gráfica
Unsatisfied with the algebraic resolutions to one unknown inequations presented by most of our sophomore students we decided to research ways of contributing to the teaching of inequations algebraic resolutions by means of a graphic functional approach. While interviewing some Mathematics teachers we realized they did not know such approach. We decided to di

30. A contribution to the study of linear programming / Uma contribuiÃÃo ao estudo da programaÃÃo linear
The Linear Programming is quite useful to obtain optimal solutions for problems related to several areas of science, such as, industrial engineering, food industry, health science, mining, transport, among others. This work makes a review about linear programming, producing a didactic-scientific text that presents a consistent theoretical base of the main co

31. Construções geométricas: uma alternativa para desenvolver conhecimentos acerca da demonstração em uma formação continuada
The purpose of this study is to analyze a sequence of activities carried out with in service teachers, aiming the construction of the definition of line bisector of a segment and, from this definition, to allow them to demonstrate inherent properties of this mathematical object. Moreover, the study also aimed that the teachers were able to justify it mathema

32. Uma abordagem histórico-filosófica na educação matemática : contribuições ao processo de aprendizagem de trigonometria no ensino médio
The aim of this research was the construction process of a historical-philosophical approach through a historical reconstruction of Trigonometry, in which we carried through a documental research on the basis of History of Mathematics textbooks, particularly those that deal with the History of Trigonometry. We used a qualitative methodological approach, in w

34. Síntese de biodiesel: uma proposta contextualizada de experimento para laboratório de química geral
The contextualized understanding of concepts in Chemistry by students from other areas is a challenging task. In this experiment, the synthesis of biodiesel is done by base catalyzed transesterification of refined soy oil with methanol at room temperature and common glassware found in any chemistry laboratory. The proposal permits introducing several concept

35. Reaprender fraÃÃes por meio de oficinas pedagÃgicas: desafio para a formaÃÃo inicial. / To learn again fractions by means of pedagogical workshops: challenge for initial formation
The primary concern of the present research is fractionsâ content, focusing on the relevance of such mathematical content to logical-mathematical acquisition. Firstly, a discussion on pedagogueâs early instruction is done, since this professionalâs grounding enables her to teach Mathematics in early series and so it needs to be improved. The aim of this s

36. Conceito de área: da composição e decomposição de figuras até as fórmulas
The objective of this research is to investigate across the use of composition and decomposition of plan forms, until the demonstration of the formula, how the area concept can be showed in the significative and motivating way to the students. To do it, we direct our studies from some hypothesis: How the reconfiguration processes of polygon forms
