Uso de GeoGebra para la comprensión geométrica de la definición formal del límite y su efecto en el rendimiento académico en la Unidad Educativa el Porvenir del Carmen

Abstract

Abstract: The objective of this study was to determine the influence of using GeoGebra for the geometric understanding of the formal definition of a limit on the academic performance of third-year high school students at Unidad Educativa El Porvenir del Carmen. In this regard, the research was framed within a positivist paradigm as a quantitative study, with a descriptive-correlational scope and a quasi-experimental design. The sample consisted of 15 students in the experimental group and 20 in the control group, selected through intentional non-probabilistic sampling. A pretest was administered to diagnose prior knowledge related to the formal definition of a limit, followed by the implementation of a didactic sequence in which only GeoGebra was used in the experimental group. This sequence was evaluated using an observation guide and a performance rubric. Afterwards, a posttest was applied, and the Wilcoxon test revealed a significant difference in the averages of both groups. Finally, it is concluded that the use of GeoGebra for the geometric understanding of the formal definition of a limit has a positive influence on academic performance at Unidad Educativa El Porvenir del Carmen.
