Uso de GeoGebra para la interpretación gráfica y algebraica de funciones matemáticas en estudiantes de segundo año de bachillerato

Abstract

Abstract: This research explores the use of digital tools in mathematics teaching, with GeoGebra being the digital resource used for the algebraic and graphical interpretation of functions. The study was conducted with a sample of 31 second-year high school students from the Rumiñahui Educational Unit, using a quasi-experimental method with a quantitative approach. A pretest and posttest were administered to the students to evaluate the effectiveness of using GeoGebra in the interpretation of functions, through the implementation of teaching sequences, with one traditional class without the use of the tool and another with an innovative pedagogical intervention using GeoGebra, in which positive results were obtained, by increasing students' understanding of the abstract concepts involved in functions, especially when interpreting the graph and rationalizing it with algebra. In conclusion, the results of the research show that the implementation of teaching sequences in a class with digital tools such as GeoGebra significantly improves the algebraic and graphical interpretation of mathematical functions.
