Fluxogramas: análise da proposta de uma coleção de livros didáticos de matemática

Abstract

In this research, we analyzed the work proposal with flowcharts in a collection of Mathematics textbooks from the final four years of Elementary School. The choice of this theme was due to the emphasis given to working with flowcharts in Mathematics skills present in the Common National Curriculum Base (BNCC) and the need to analyze the possibilities of working with this type of algorithmic representation in the classroom. In our text, we discuss the concepts that are inherent to the research objective, such as the relationship between the development of mathematical knowledge and the bases for Computational Thinking, considering flowcharts as the focus of discussion. Our theoretical basis had as main references the works of Wing, Silva and Rêgo and our research, of a qualitative nature, was obtained as a documentary and bibliographic study. We highlight in the study the specific skills of the BNCC aimed at the use of flowcharts as a tool to promote mathematical capabilities, which guided us in the analysis of the proposal presented in the selected collection of textbooks. The results of our analysis pointed to the inadequate use of flowcharts regarding the logical structuring of mathematical arguments. Furthermore, we verified that some skills presented in the text of the BNCC related to the work with flowcharts were not fully acknowledged by the author. Thus, we emphasize the need for an appreciation of work proposals with flowcharts in Mathematics textbooks, especially concerning to the prior knowledge of the flowchart structure by the students.
