O uso de experimentos de física no estudo da função afim

Abstract

This research aims to develop a didactic sequence that can help Mathematics teachers in the processof teaching and learning in relation to the concept of affine function, using experiments of Physics. In this regard, it was done a previous analysis through na investigation questionnaire given to eighteen teachers from state education network of the 14th teaching coordinating, on which there were information about theirteaching experience and, if in any moment, they use experiments in their classes.The research is divided in four stages. In the first stage, it was applied a diagnosis questionnaire to teachers (a priori questionnaire), in order to highlight situations experienced in life as teacher. In the second stage, it was realized two workshops with two hours duration each, to eleven teachers, in which it was showed experiments of physics and how they can help in learning the content of affine function. In the third stage, it was applieda diagnosis questionnaire again (a posteriori questionnaire) that aimed to verify how the themes approached in the didactic sequence could help teachers in learning development and in the construction of the linear function concept. We finalized these stages analyzing the answers of the questions in these questionnaires. This analysis served to the final organization of the didactic sequence, which will contribute to teachersdevelop their classes about affine functions clearly and objectively through these experiments. The educational product of this dissertation will be a didactic sequence proposal developed throughout the research.
