Mathematical modeling as a bridge between the high school classroom and real life: contributions to think about the production of meaning

Abstract

In this article, we analyze meanings produced by high school students during the development of a landscape of investigation that involved immersion in the different phases of a mathematical modeling process. The problem addressed here is related to vehicular traffic between two Argentinian cities, and we focus on the aspects that are linked to the development of critical citizenship from a socio-critical perspective of modeling. We used a qualitative case study methodology. The scenario proved to be adequate for allowing students to reflect on the real-world problem. Familiarity with the situation facilitated its connection with the students' background, who, by developing an intentional mindset, were able to see meaning in the actions carried out and learn with others. We consider that the students assume a critical attitude, given that they pay attention and react to a situation that generates difficulties in the cities where they live. In order to address its resolution, they think autonomously and make balanced decisions that are discussed and justified within small groups as well as with the whole class. We point out, as a limitation of the scenario set up for this study, that the debate generated around the mathematical notions involved turned out to be insufficient.
