The USAID and the teaching of mathematics in Rio Grande do Norte
(Bolema-mathematics Education Bulletin-boletim De Educacao Matematica, 2008-01-01) [Artigo]
In the 1960s occurred great changes in the general education and, specially in the mathematical teaching, throughout Brazil. Besides the Law Diretrizes e Bases for Education (law 4024/1961), such changes also was occurred ...
Trends in Brazilian academic production in the History of Mathematics Education: directions from EBRAPEM
(Bolema-mathematics Education Bulletin-boletim De Educacao Matematica, 2009-01-01) [Artigo]
The number of papers on History of Mathematics Education presented at EBRAPEM (Brazilian Meeting of Graduate Students in Mathematics Education) has increased significantly between 2003 and 2008. This article presents a ...
VOICES FROM THE SOUTH: DIALOGICAL RELATIONSHIPS AND COLLABORATION IN MATHEMATICS EDUCATION
(Internationalisation and Globalisation In Mathematics and Science Education, 2007-01-01) [Artigo]
This chapter presents a collaborative experience between two neighbouring countries from South America: Argentina and Brazil. Our purpose is to share a model of international collaboration that we consider to be an alternative ...
On an approximate analytical solution to a nonlinear vibrating problem, excited by a nonideal motor
(Nonlinear Dynamics, 2007-12-01) [Artigo]
This paper analyzes through Multiple Scales Method a response of a simplified nonideal and nonlinear vibrating system. Here, one verifies the interactions between the dynamics of the DC motor (excitation) and the dynamics ...
The relationship between differential equations with piecewise constant argument and the associated discrete equations, via dichotomic maps
(Dynamics of Continuous, Discrete and Impulsive Systems Series A: Mathematical Analysis, 2005-12-01) [Artigo]
Dichotomic maps are considered by means of the stability and asymptotic stability of the null solution of a class of differential equations with argument [t] via associated discrete equations, where [.] designates the ...
Boundary oscillations and nonlinear boundary conditions
(Comptes Rendus Mathematique, 2006-07-15) [Artigo]
We study how oscillations in the boundary of a domain affect the behavior of solutions of elliptic equations with nonlinear boundary conditions of the type partial derivative u/partial derivative n + g(x, u) = 0. We show ...
Remarks on the normal bordism forgetful homomorphism
(Far East Journal of Mathematical Sciences, 2009-09-01) [Artigo]
Assume that X is an oriented smooth (n+k)-manifold. Then the kernel of the forgetful map F considered in this work consists of immersions f: Mn → X nullbordant as a continuous map. Using an exact sequence of normal bordism ...
Husserl's two notions of completeness: husserl and hilbert on completeness and imaginary elements in mathematics
(Synthese, 2000-12-01) [Artigo]
In this paper I discuss Husserl's solution of the problem of imaginary elements in mathematics as presented in the drafts for two lectures he gave in Göttingen in 1901 and other related texts of the same period, a problem ...
Escolas técnicas agrícolas e educação matemática: histórias, práticas e marginalidade. Educação matemática e formação para o trabalho: práticas escolares na Escola Técnica de Vitória - 1960 a 1990
(Bolema-mathematics Education Bulletin-boletim de Educacao Matematica, 2008-01-01) [Resenha]
