Diálogo em sala de aula: interações mediadas pela investigação matemática

Abstract

This research consists of investigating the interactions that took place between the participants of a Mathematical Research class, where the content covered was the sine function and its parameters. This is a qualitative research, whose objective is to answer the question: "Can the interactions that can be triggered by Mathematical Research have the potential for learning?" For this purpose a sequence of four activities were used that were applied to high school students. Each stage of this research is based on the theoretical presuppositions of Mathematical Research, as pedagogical practice and the analysis of the data are based on the Dialogue. The instruments used to collect data were about audio recordings, written records of the students and teacher records. It was possible to verify that the interactions triggered by Mathematical Investigation have potential for learning. Related to the research was produced an educational product that gathered the activities developed for this research, in addition to others that will be part of the scripts and that will be available to teachers through a link available on the page of the master program. The educational product is composed of activities that may help teachers of Mathematics in their classes.
