Translação e reflexão do gráfico da função quadrática utilizando o GeoGebra em dispositivos móveis

Abstract

The use of technological resources in the teaching of mathematics is a widely discussed topic and is seen by many as inevitable, given the justification that their use enhances teaching and learning. It has been observed that a significant proportion of students lack interest in learning mathematics because they find it difficult, challenging teachers to try all possible technologies and develop new teaching proposals to make this part of the curriculum more appealing to students. The use of software, whether in computers or in mobile devices such as smartphones and tablets, can be considered as one of these 'new' teaching proposals. This paper presents the results of a study whose objective was to investigate the contributions of the GeoGebra application on mobile devices to the process of understanding the graphical content of quadratic functions in a first year high school class at the Centro de Ensino Professor Robson Campos Martins, in Paço do Lumiar - MA, with the aim of verifying if there is a greater learning outcome with the use of this software. Using a research-action methodology and a qualitativequantitative method, data were collected and analysed. The instruments used for data collection were questionnaires and activities using GeoGebra on mobile devices. At the end of the research, students indicated that the use of the GeoGebra app on their smartphones greatly facilitated their understanding of the study of quadratic function graphs, suggesting that its use had a positive impact on the teaching-learning process.
