Aspects of theory on semiotics representations registers expressed by graduates in mathematics

Abstract

In this paper, we seek to analyze responses given by a group of graduates in Natural Sciences and Mathematics, specialization in Mathematics (NSM-SM) from the Federal University of Mato Grosso, Campus of Sinop, compared to a set of four episodes adapted by us from what is shown by Maranhão & Igliori (2003), Duval (2009, 2011, 2011b) that deal with situations that may arise in the math educational context and that were analyzed based on Duval's theory on semiotic representation registers. Thus, the initial objective of this paper was to determine whether the interpretation given by scholars to the proposed episodes stand out the explicit or implicit way the elements of Duval's theory on semiotic representation registers. This analysis shows the lack of knowledge from graduating students about this theory, which indicates the need to approach this type of issue in order to improve the training of future teachers.
