Mathematics and interdisciplinarity: a study about teaching materials

One of the great difficulties inside the school context is the interdisciplinarity in teaching and learning of mathematics. In general, there are some barriers on relating their conceptual content to their applications and also the integration of mathematics to others sciences and subjects. In this article, we have analyzed four didactic books of elementary and middle school adopted in "Colegio Estadual Polivalente de Curitiba" (PR), in order to demonstrate whether and how the books associate mathematics in other subjects and how this interdisciplinarity can be developed in school environment. In relation to investigation's techniques, we have analyzed the mathematical content present in previously selected didactic books and also the realization of semi-structured individuals interviews with teachers who uses those materials. We conclude that the didactic books allows the association of mathematical content to others disciplines and that there is a need of a development of a collective work with teaching staff to stimulate the interest, curiosity and the capacity of solving problems in the students.
