Verificação da autenticidade de uma situação-problema vivenciada no âmbito da Modelagem Matemática

Abstract

The aim of this article is to investigate the authenticity of a Mathematical Modeling activity proposed in a Mathematics Degree class in the subject “Mathematical Modeling” offered at the Federal Institute Campus São Raimundo Nonato - PI. The work was organized in three stages: (1) a bibliographical survey was carried out on the definitions of Mathematical Modeling according to different authors in the field, the planning of activities of this nature, their phases/stages, as well as a study on what authenticity is and how to assess the level of authenticity within the scope of Mathematical Modeling; (2) a relevant methodology was organized, based on qualitative research, to investigate the level of authenticity of the activity developed through a problem situation experienced in the classroom concomitantly with the students and the teacher; (3) the experience was discussed and the level of authenticity of the activity was assessed. As a result, according to the design proposed by Almeida and Omodei (2022), level 2 (intermediate) of authenticity was achieved. However, the students could have reached a higher level if they had used the mathematical, empirical and technological tools (software) available to them, as well as if they had extrapolated the problem situation to external contexts. Therefore, in addition to the interest and questioning provided to the students (trainee teachers), it is clear that the research has the aim of encouraging teachers to plan activities of this nature more effectively.
