O ensino da representação gráfica da função logarítmica por meio do geogebra: um levantamento de estudos

Abstract

ABSTRACT Mathematics teaching in secondary education has been the subject of extensive discussion in the field of Mathematics Education, particularly regarding the methodologies adopted to promote students' conceptual understanding of mathematical content. Among the topics covered at this educational level, logarithmic functions occupy a prominent position due to their theoretical relevance and their applications across different fields of knowledge. However, many students experience difficulties in understanding this topic, especially with respect to interpreting its graphical representations and establishing connections among different mathematical representation registers. In this context, the use of digital technologies in mathematics education has been recognized as a valuable approach to expanding pedagogical strategies and enhancing the visualization of mathematical concepts. Therefore, the main objective of this study is to investigate the contributions of the GeoGebra software to the teaching of the graphical representation of logarithmic functions through a survey of academic studies in the field of Mathematics Education. This research is characterized as qualitative, bibliographic, and exploratory, and was conducted through a survey of academic studies available in the Brazilian Digital Library of Theses and Dissertations (BDTD), maintained by the Brazilian Institute of Information in Science and Technology (IBICT). The analysis of the selected studies made it possible to identify different pedagogical approaches related to the use of GeoGebra in the teaching of mathematical functions. The results indicate that the use of this software enables the dynamic visualization of function graphs, promotes the integration of different mathematical representation registers, and contributes to the development of more investigative and interactive teaching practices. It is concluded that GeoGebra has significant potential as an instructional resource for teaching the graphical representation of logarithmic functions, contributing to making mathematics teaching more dynamic, visual, and meaningful for students.
