O ensino de probabilidade baseado em uma sequência didática para o exercício de literacia probabilística

Abstract

This research presents a study with seven students from a class in the second year of high school, which sought to develop activities in order to lead students to exercise probabilistic literacy. From the research question: “What aspects contribute to the development of probabilistic literacy in 2nd year high school students, using Didactic Engineering as a methodological device mediated by a didactic sequence that leads to decision making? ”, We sought to study concepts that indicate the exercise of probabilistic literacy in the education of this theme through a didactic sequence. The theoretical framework that supported this research was statistical and probabilistic literacy. This qualitative study was developed using the assumptions of Didactic Engineering as a research methodology and as a methodological device in the classroom. Having in mind the goal of investigating whether and how the development of probabilistic literacy occurs through a didactic sequence, which leads to decision making built gradually, through Didactic Engineering as a methodological device; the research also sought to validate the hypothesis raised: a didactic sequence supported by Didactic Engineering as a methodological device dealing with language, probabilistic approaches, discussions about equiprobable spaces or not, and decision making can lead students to develop and exercise aspects that make up literacy probabilistic. After obtaining and analyzing the data, it was possible to verify the aspects that contributed to the exercise of probabilistic literacy, as well as to validate the hypothesis raised. As it is a professional master's degree, this didactic sequence combined with a second one made up the educational product. The results of this research point to the need to work on the theme of Probability since the early years, combined with probabilistic literacy with a view to training the student in a critical way.
