Modelagem matemática no curso técnico de informática integrado ao ensino médio: um trabalho interdisciplinar

Abstract

In this research, we present a study on an interdisciplinary approach in activities of Mathematical Modeling in a first year of the Informatics technical course integrated to High School. The objective is to investigate the existence of contributions of an interdisciplinary approach in Mathematical Modeling about the re-signification of mathematical concepts and the learning of new concepts, efforts have been made to analyze the students' actions in dealing with the contents that emerged in the development of the activities and to infer about the influences of teachers' interventions in mediating these actions during interdisciplinary work. For that purpose, three activities of Mathematical Modeling were developed together with other teachers of the class, mainly the teacher of the specific area of the course, of Computer science. The Mathematics’ classes moments were recorded in video, as well as the audios of the conversations of the students’ groups. Subsequently these recordings were transcribed and episodes of analysis were selected. In each episode, we tried to present reflections on the auxiliary questions of investigation coming from the research objective. We infer, among other things, that the development of Mathematical Modeling activities contributed to the re-signification of mathematical concepts and to learning new concepts, since as the students developed the activities, concepts studied in previous years and new concepts emerged, so they could build relationships between them and relate them to an extra math context. As an educational product, the result of this research, we have built a material that can support the Basic Education teacher who decides to work with Mathematical Modeling. This material is available in the form of a Mathematical Modeling Website / Blog, which can be accessed at https://modelagemmatematica.wordpress.com.
