Educação estatística na sala de aula: uma proposta de sequência didática para o ensino fundamental

Abstract

This monograph aimed to develop a didactic sequence for discussion of graphics in a class of the 7th year of Fundamental Teaching of a public school in the municipality of Conde, Paraíba. The proposal aimed to discuss the statistical thinking and consequent statistical literacy of students in understanding and interpreting graphs. To support the research, we resorted to current official documents, such as the National Curricular Common Base - BNCC (BRASIL, 2017) and the National Curriculum Parameters - PCN (BRASIL, 1998), and other authors who discuss the theme of the study. The methodology used was characterized by being an exploratory research of the qualitative type, carried out in a field study in March of this year, with 23 students from the 7th year in a public school in the municipality of Conde - PB. The results after the elaboration and execution of the didactic sequence indicated that the proposed activities allowed a new vision of the students regarding the graphic representation, as they understood the process of building a graphic, using or not technology, in mathematics classes, which was their importance to facilitate the interpretation and analysis of data. We conclude that the planning of activities that discuss the problematization of everyday situations of the student and the use of electronic spreadsheet software contributed to the understanding and interpretation of graphs by the participants, since the resources used in each moment of the investigation allowed the analysis of data. and a reflective positioning in the face of discussions. Finally, the didactic sequence was an organizing resource for the researcher and the participating class, as it collaborated for the construction of statistical thinking during the application of the proposal, being considered a necessary resource for the school environment.
