Uma proposta de metodologia de ensino de logaritmos através da tecnologia

Abstract

Preparing tomorrow's teachers to use technology is one of the most important issues in today's teacher education programs. After all, the advent of the democratization of digital access through the use of smartphones, as well as the need arising from remote teaching during the Covid-19 pandemic, brought new and irreversible possible paths. Given this scenario, this work aims to address some different, broad and specific aspects of the relationship between technology, education and the teaching of logarithms. For this purpose, we go through the tensions that involve technology and school, the historical and formal conceptions of the concept of logarithms and the possibilities of innovations in the context of the mathematics classroom. The approach of this research was not conceived only in the literary field. In addition to bibliographic surveys, in response to the concerns that arose from the dialogue with these authors, we bring a possible script for using the Geogebra software for teaching logarithms. The script consists of a didactic sequence that addresses some logarithmic operative properties. Its intention is to inspire innovative teaching practices that promote investigation and student autonomy, so that the production of their mathematical knowledge is really meaningful and solid. We also bring a discussion guide that can support the teacher in the implementation of these activities. In this way, we aim to contribute to the construction of a path of innovation in mathematics teaching, which embraces the powers and circumvents limitations.
