A produção de significados diante de diferentes enfoques de probabilidade

Abstract

Our research problem is to investigate the production of a set of probability tasks, using technological resources, for the teaching and learning processes of students in Basic Education. Therefore, this work proposes an alternative for teaching probability based on a sequence of tasks that constitute the educational product and provide students with different perspectives on the object of probability. The study falls within the field of Mathematics Education, which studies teaching and learning in the areas of statistics, probability, and combinatorics, and aims to identify conceptions and perspectives on the teaching and learning of probability. The discussions on this topic were based on the propositions of Batanero et al (2016) and (GAL, 2005) on probabilistic literacy, that is, studies that highlight the problems faced by students when they encounter probability concepts and need to make decisions based on such concepts. This research proposes using the Semantic Fields Model (LINS, 1992) to investigate the production of different meanings by students when exposed to different concepts of probability. The methodology is qualitative, studying a sequence of tasks, which will be present in the educational product, and elements of reading in the students' speech, that is, the production of meanings, with 7th-grade students from the state school system in the municipality of Dona Euzébia, MG. The analysis was carried out through the transcription of audio recordings of the students' speech, among other characteristics described in the theoretical framework. The investigation provided students with the opportunity to produce different meanings for the concepts of probability, using computer simulation in some tasks. Students discussed the meanings they produced among their peers, defending their point of view, and through the use of technology, they were able to expand their knowledge in different approaches to probability, with practical and experimental activities.
