Proposta de ensino de função exponencial com software Geogebra fazendo uso do Geogebrbook

Abstract

This dissertation, linked to the Professional Master's Program in Mathematics in the National Network (PROFMAT), aims to present, analyze, and discuss the development of an interactive digital textbook on exponential and logarithmic functions, designed as an educational product for high school students. The research is based on the theoretical contributions of authors such as Borba and Penteado (2019), Moran (2018), Kenski (2008), and Valente (2015), in addition to the guidelines of the National Common Curricular Base (BNCC, 2018). The work is based on the diagnosis that mathematics teaching faces challenges related to the abstraction of exponential function concepts, the lack of student understanding of the subject, and the difficulty in connecting theory and practice. The digital textbook is structured into eight chapters: introduction, definitions, restrictions, properties, graphs, graphical transformations, solved questions, and questions on exponential functions. The results indicate that the use of digital resources contributes to the dynamic visualization of concepts, better modeling of real-life situations, and student motivation, while also optimizing teaching by offering material that facilitates the graphical visualization of various exponential functions. The study also reinforces that technology, while a powerful tool, requires critical teacher intervention to maximize its pedagogical effectiveness. The conclusion is that the digital textbook on exponential functions constitutes an innovative educational resource, capable of promoting meaningful learning aligned with the contemporary demands of Basic Education.
