Construção conceitual de números racionais na perspectiva de Vergnaud: um estudo no 6º ano do ensino fundamental, 2024. Trabalho de Conclusão de Curso (Graduação em Licenciatura em Matemática). Universidade do Estado do Amazonas, Parintins, 2024.https://ri.uea.edu.br/handle/riuea/6864This article presents results of qualitative research (Creswell, 2010) developed with the aim of understanding how the construction of the concept of rational numbers occurs from the perspective of Conceptual Field Theory with students in the 6th year of Elementary School. Participant observation, semi-structured interviews and document analysis were used as research techniques (Marconi; Lakatos, 2021). In data analysis, the principles of triangulation were followed (Stake, 2011). The theoretical basis is based on the ideas of Vergnaud (1986; 2014). The results indicate that, from the perspective of Conceptual Field Theory, the construction of concepts occurs through conceptual fields and the situations proposed by the teacher in the classroom play a fundamental role in this process. These situations must be diversified to open space for conceptualization that interrelates the different ways of representing a rational number, which requires understanding the nature of this type of number and not just the appropriation of the definitionAcesso AbertoTeoria dos Campos ConceituaisNúmero RacionalEstratégias de EnsinoTrabalho de Conclusão de Curso
