Ensino e aprendizagem de funções exponenciais envolvendo Tecnologias Digitais de Informação e Comunicação: análise de atividades com alunos do Ensino Médio

Abstract

Digital technologies have a constant presence in our society, marking its development as they introduce innovations, expand access to information and provide diversified modes of communication, allowing new methods to emerge for teaching and learning processes. This research was developed seeking to analyze possible contributions of the use of TDIC, in the teaching and learning processes of exponential functions in a class of the 2nd grade of high school. Based on the contexts of use of technologies in Mathematics Education with the phases developed by Borba, Scucuglia and Gadanidis (2014) and Borba, Souto and Junior (2022), in Mayer's Cognitive Theory of Multimedia Learning (2009) for the evaluation of multimedia aimed at teaching, and, in the official education documents of the state of Espírito Santo, we created and applied an Activities Plan that uses multimedia and GeoGebra software to work on the content of Exponential Functions. The methodology used is a qualitative and exploratory approach, with data collected through a logbook, resolution of activities and a questionnaire. Data analyzes followed a methodological path built based on the sequential process of activities described by Gil (2002) and some Content Analysis techniques by Bardin (2021). We built four categories: Multimedia in the classroom, GeoGebra Functionalities, Graphic Transformations and Use of Mathematical Language. The categorical analyzes showed that the TDIC, used in the Activity Plan, contributed to facilitate the teaching and learning processes of the content and so that the students could perceive the main relationships that are established between the laws of the functions and their graph, through transformations between its records, using GeoGebra.
