1. Intradisciplinaridade Matemática com GeoGebra na Matemática Escolar
Resumo Neste artigo discutimos o trabalho intradisciplinar na Matemática escolar e trazemos evidências de que o uso do GeoGebra o favorece. Para tanto, questionamos o processo de disciplinarização da ciência, que contribuiu com o aprofundamento das diversas áreas, ao mesmo tempo em que impulsionou uma crescente dissociação entre elas. De igual modo,

2. Relações entre os estilos cognitivos, as estratégias de solução e o desempenho dos estudantes na solução de problemas aritméticos e algébricos / Relation between the cognitive styles, the strategies of solution and performance of the students in the solutin of arithmetic and algebraic problems
This study aimed to verify the existence of relationships between cognitive styles and strategies of problem solving, cognitive styles and the variables gender and grade, cognitive styles and student performance in problem solving, as well the performance and type of strategy used in solving problems. To this end, was asked 168 students to the first, second

3. 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

4. Arithmetic fuchsian groups identified in quaternion orders for the construction of signal constellations / Grupos fuchsianos aritmeticos identificados em ordens dos quaternios para construção de constelações de sinais
Within the context of digital communications system in homogeneous space in particular, in hyperbolic spaces, it is necessary to establish systematic procedure for the construction of lattices O ; as the basic entity for construction of eometrically uniforms signal constellations. By this procedure we identify the algebraic and geometric structures to constr

5. Saberes e concepções de educação algébrica em um curso de licenciatura em matemática
Investigations have shown that difficulties experienced by students when dealing with topics of Algebra, across a range of schooling levels, may be rooted in certain conceptions of Algebra Education, either their own or those held by their teachers. These conceptions provide the basis for knowings held by teachers and students in Teaching Degree programs in

6. Estudos das visões sobre álgebra presentes nos parâmetros curriculares nacionais de matmática do ensino fundamental em relação a números e operações
The aim of this study is to investigate the views on Algebra, in contents concerning Numbers and Operations, present in the Mathematics National Curricular Parameters (PCN) for Elementary Education. Therefore, in this documental analysis adopting qualitative approach, the content analysis proposed by Bardin (1977) was applied by means of enunciation analysis

7. A axiomatização da aritmética e a contribuição de Hermann Günther Grabmann
This research had as purpose the epistemology development of the knowledge object, number, in its formation as mathematical entity. It became evident that, in the end of the XIX century, the need of this formation caused many controversies, because number was understood as gift by God and consequently, considered something perfect. To the development of this

8. Introdução da noção de variável em expressões algébricas por meio da resolução de problemas: Uma abordagem dinâmica
Students difficulties in writing and interpreting algebraic language, particularly in comprehending the meaning of variable have been discussed by such researchers as Kieran, Küchemann, Arcavi and others. In this research, we evaluate a teaching proposal in which it is aimed at explaining established relations between elements of circumstances of proportion

9. Concepções do professor de matemática sobre o ensino de álgebra / Mathematics educators conceptions about the teaching of algebra
This research has investigated the Mathematics educators conceptions about the teaching of Algebra by comparing them to Algebras conceptions proposed by Usiskin and to the approaches to the teaching of Algebra suggested by Bednarz, Kieran and Lee. Qualitative analysis has been undertaken by means of the software C.H.I.C. and quantitative ones from teachers a

10. Livros didáticos e a matemática do ginásio: um estudo da vulgata para a reforma Francisco Campos
This study analyses how Mathematics, as a school subject, developed itself within the first years of its creation, from the so-called Francisco Campos Reform, in 1931. Based on the ideas of academics such as André Chervel and Roger Chartier, among others, the study intends to answer the following question: How Brazilian school books, which have been written

11. A experiência norte-americana de fusão da aritmética, álgebra e geometria e sua apropriação pela educação matemática brasileira
This dissertation is a study on the North American experiment of merging subjects such as Arithmetic, Algebra and Geometry, and the influence of this experiment over the Mathematic education in Brazil. We have analyzed a few changes occurred in the secondary school in North America between 1890 and 1930, and also how Professor Euclides Roxo used that initiat

12. A Matemática escolar nos anos 1920: uma análise de suas disciplinas através das provas dos alunos do Ginásio da Capital do Estado de São Paulo
This study tries to characterize pedagogical practices in Arithmetic, Algebra, Geometry/Trigonometry in the 1920s, in the oldest official School of the State of São Paulo. These studies analyse questions, which create the Mathematics subject according to the Reformation Francisco Campos. Based upon the field of studies named history of school subjects, the
