Um estudo dos registros de representação semiótica aplicado à problemas da Olimpíada brasileira de Matemática das Escolas Públicas (OBMEP)

Abstract

The discipline of Mathematics is considered to be the most difficult for some students. There are several reasons to justify school failure in learning this content. The difficulty that the students have in understanding Mathematics due to its abstract character deserves, in the present work, a highlight. Thus, we consider the importance of solving mathematical problems, from which we can: use knowledge of the students' daily life as a starting point for the development of their knowledge; Teach mathematics from a meaningful point of view and arouse interest in mathematics. Therefore, in the present work we have as objective: To analyze what are the contributions that Raymond Duval's theory, regarding the study of the Registers of Semiotic Representations, has for a better performance of students in OBMEP. For this, we are resorting to a qualitative research, which until the present moment reveals some results, such as: a higher frequency of the registration of semiotic representation of the natural and symbolic numerical language in the answers of the subjects of the research.
