MEANING OF STOCHASTIC CONCEPTS FOR MATHEMATICS STUDENTS Liliana Tauber

In this poster we present an exploratory study aimed at identifying the students’
difficulties in understanding stochastic concepts that appear while teaching and learning Statistics within the Mathematics Major.
Our objective was to investigate the understanding of those statistical concepts that have higher semiotic difficulty because they are related to other, different statistical objects that should have been previously learned. We also try to describe the main difficulties in understanding these concepts.
Once we identify these data, we use the Theory of Semiotics Functions (Godino, 2003) and research in Statistics Education such as, Batanero (2001), Cobo (2003), Espasandin Lopes and Lanner de Moura (2002), to extract some didactic sequences. The primary objective of these sequences is to start from the students’ understanding difficulties and proceed to elaborate strategies of qualification for future teachers.
