Geogebra no ensino de funções exponenciais: uma sequência didática investigativa para o ensino médio

Abstract

This research aims to develop an Investigative Sydactic Sequence (IDS) that articulates GeoGebra and the exponential function, so as to understand the characteristics of the sequence's development using this software as a tool for teaching the proposed mathematical subject. To further this investigation, an analysis was conducted on the use of Information and Communication Technologies (ICTs) in the classroom, the characteristics of GeoGebra, and the possibility of its use as a teaching resource in mathematics classes. A survey was conducted, from which scientific papers present in the Proceedings of the National Meeting on Mathematics Education (ENEM) from the X to the XIV ENEM, were selected. These papers explored the use of GeoGebra in the teaching and learning of functions, particularly the exponential function. The research methodology used was qualitative, bibliographic, and exploratory, aiming to understand the articulation between the construction of the IDS with the use of the software and the exponential function. This highlights the need for new methodologies using technological tools in mathematics classes. In conclusion, the results point to the need for planning and organizing sequenced and interconnected classes by level; promoting active student participation in classroom activities; encouraging problem-solving; developing critical thinking; encouraging classroom collaboration; and investigating the mathematical subject being discussed
