Letramento probabilístico : um olhar sobre as situações de aprendizagem do caderno do professor
Abstract
The aim of this research was to analyze the concept of probability through the diversity
of semiotic representation records arranged in the statement of the tasks (learning
situations) contained in the second volume of the Teacher's notebook for the second
high school series and their possible contributions to the development of probabilistic
literacy. The study was based on Raymond Duval's Theory of Semiotic
Representations and on the Probabilistic Letters of Iddo Gal. We sought to answer the
following research questions: What and how are the records of semiotic representation
in the learning situations proposed in the teacher's book? Do such records contribute
to the development of probabilistic literacy? In order to fulfill the purposes of our work,
we resorted to bibliographical and documentary research and based on our theoretical
contributions, we analyzed the content of four learning situations. Among the several
records of semiotic representation, the tree diagram was little explored in the proposed
tasks. The mobilization and coordination of records of this nature has the function of
contributing to the construction of concepts, but in the case of problems of
combinatorial analysis, they did not present contributions to the development of
probabilistic literacy, due to the absence of internal connections between the basic
notions of With the calculation of probabilities.
