In this research we present a meta-comprehension about the research on Mathematics Education developed in Brazil through an hermeneutical analysis of the texts presented and discussed on the III SIPEM - International Seminar on Mathematics Education occurred on 2006. We present the trends that were identified in the research and emphasize the interrogations, questions and problems they address as well as their scientific, philosophical, and methodological rigor. We present the nucleus of ideas present in Mathematics Education research in Brazil as we transcend the individual production of research, focusing on the references of national and international authors. We conclude that the research analyzed has been clearly designed, introducing conceptions of and ways of working with Mathematics that address issues related to education, society, culture, teaching, learning, and history of Mathematics Education.

In relation to United Nations Literacy Decade (2003- 2012), are being developed in Brazil many public policies on education and literacy. The results of these public policies indicate both noisy conquest of some advances as the worsening of many historical problems. Among these, we highlight the result of silencing of discussion around the concept of restricted and rudimentary literacy, on which, in line with neoliberal political model, are based educational policies and corresponding systems assessment of skills and competencies of reading and writing, which it is hoped that students learn and which are defi ning the role of the teacher as a mere provider of strategies for such learning. Based on this hypothesis, we present, in a tone of critical balance, refl ections on the Decade of Literacy in order to contribute to the discussion of problems and perspectives for teaching reading and writing in Brazil.

In this article we discuss some qualitative and geometric aspects of non-smooth dynamical systems theory. Our goal is to study the diagram bifurcation of typical singularities that occur generically in one parameter families of certain piecewise smooth vector fields named Refracted Systems. Such systems has a codimension-one submanifold as its discontinuity set. © 2012 Elsevier Ltd.
