Um estudo sobre a aprendizagem das funções quadráticas com a mediação do Software Geogebra

Abstract

The issue in question came to light due to the difficulty presented by the students in learning the quadratic functions and also considering the growing advance of technology, in which we perceive the necessity of a greater insertion of technological resources, such as geogebra software, in the process of learning this content. In view of this, we can highlight the problem of this research by means of the following question: how can the use of geogebra software contribute to the learning of concepts related to the content of quadratic functions? Based on this problem and based on the socio-interactionist theory of Vygotsky, and its conceptions about mediation, the process of internalization, the zone of proximal development and the formation of concepts, this research has as general objective to analyze the use of software geogebra, as an educational tool inserted in a learning process with mediation, and its contributions to the construction of concepts related to the content of quadratic functions. The methodology of this work has a qualitative method of research, of the exploratory type, being taken elements of a participant research, once a methodological intervention was carried out with the purpose of analyzing the use of the software geogebra as instrument of mediation in the learning of quadratic functions . The subjects of the research are students of the 1st grade of high school in a public school in the municipality of Massapê-Ce. The instruments for data collection consisted of field diaries, questionnaires to identify learning and test of knowledge probing. Based on the analysis of the data collected during the field research, it was noticed that the learning of the quadratic functions with the mediation of the software geogebra and the teacher, was satisfactory mainly with regard to the study of their graphic representations.
