13. Composição e decomposição de figuras geométricas planas por alunos do ensino médio
The purpose of this research is to study the calculation of the figure area by the composition and decomposition of plain geometric figures, by students of the third grade of a public High School in the city of Jacupiranga. To do that, it is presented to the students a diagnostic test made up of two activities, with the objective of checking if they has the

14. Os registros de representação semiótica mobilizados por professores no ensino do teorema fundamental do cálculo
A disciplina de Cálculo Diferencial e Integral consta na grade curricular de vários cursos da área de Ciências Exatas e também de outras áreas, por tratar de conceitos que permeiam vários campos de Ciência. Seu ensino e aprendizagem tem sido alvo de muitas pesquisas devido aos altos índices de desistência e retenção comprovados, a fim de propor a

15. O conceito de independência e dependência linear e os registros de representação semiótica nos livros didáticos de Álgebra Linear
This research aims to investigate which semiotic representation registers are most used in Linear Algebra textbooks in the presentation and study of the topic linear independence. The mathematics textbook is a resource much used by the teachers in its work. They present many representation registers, which can to be analyzed qualitatively to assess their pot

16. Articulação entre Álgebra Linear e Geometria - Um Estudo sobre as Transformações Lineares na Perspectiva dos Registros de Representação Semiótica
This study addressed questions related to the teaching and learning of Linear Algebra in Higher Education. More precisely, it involved the design of activities which concerned the mathematical object linear transformations and which engaged learners in exploring the conversion of registers in a dynamic geometry environment. The aim was to investigate the lea

17. A utilização do livro didático pelo aluno ao estudar integral
This paper investigated students use of the text book when learning the mathematical object Integral. Its aim was to map the indications of strategies used by students in order to: 1. situate the proposed theme in the student book; 2.extract the main ideas and the strategies used by the author, summarizing them in a scheme; 3. solve the exercises proposed in

18. Explorando equações cartesianas e paramétricas em um ambiente informático
This research has as objective verify if in a computer science environment allows to the student to recognize some curves properties through representations and graphical interpretations in dynamic way with the use of parameters for one comprehension better of its equations. We verified that the articulating between the points of view cartesian and parametri

19. Transição da educação básica para o ensino superior: a coordenação de registros de representação e os conhecimentos mobilizados pelos alunos no curso de cálculo
O presente estudo teve como objetivo investigar como a coordenação de registros contribui para a explicitação dos conhecimentos mobilizados por alunos ingressantes no Curso de Cálculo, frente a tarefas organizadas com base no conceito de função. A pesquisa fundamentou-se na teoria dos Registros de Representação Semiótica de Raymond Duval, destacand

20. A noção de integral em livros didáticos e os registros de representação semiótica
Teaching and learning Integral considered basic in the field of Mathematics Education courses, for many times it has focused on a traditional methodological practice based on: definitions, theorems, properties, examples and tests. That methodology has been contributing to a very high rate of abandonment and failure. In teaching this subject, even if we have

21. Introdução ao conceito de função: a importância da compreensão das variáveis
This research aims to introduce the concept of function throughout the comprehension of the dependable and undependable variables, and of the relation between them. Its fundaments are on the Didactics Engineering principles by the creation and application of a teaching activity sequence and a posterior analysis of the collected data. It is based on Raymond D

22. Conceito de área: uma proposta de ensino-aprendizagem
The objective of the research is to study phenomena that influence the teaching and learning of the concept of area in Ensino Fundamental (students aged 7-15). It presents a teaching proposal for the concept of area and a reflection about the learning of this concept through a teaching sequence involving the decomposition and composition of plane figures. Th
