Comprensión de conceptos y resolución de ejercicios sobre funciones cuadráticas, mediante la aplicación del software Geogebra, en estudiantes del primer año de bachillerato general unificado de una unidad educativa local

Abstract

The present research had the purpose to promote the understanding of concepts and the solution of exercises on quadratic functions through the use of GeoGebra software. For this research, a quasi-experimental methodological design was chosen with only post-test and control group. The study was carried out in a public establishment in the city of Azogues, Ecuador, with 30 students who belong to the intervention group and another group of 30 who belong to the control group. A diagnostic evaluation was carried out which allowed to know that the two groups were in equal conditions. The intervention, in group one, consisted of the implementation of 15 hours class of BGU with GeoGebra software in the establishment's computer lab, while in the other group the 15 hours of classes were held in the regular classroom without using GeoGebra. The results allowed us to establish that working with software has a positive influence about the understanding of concepts and the problem solving related to quadratic functions exercises. The results on 12 points showed that the students of the control group reached an average of 10.20 points (SD 2.02) and those of the control group 6.57 points (SD 2.47), which is considered a significant difference when making a comparison with the non-parametric test statistic U of Mann Whitney (z = -4.812, p = 0.000, unilateral, Cohen's d 1.61).I The importance of GeoGebra software to facilitate the teaching of the subject of mathematics for the students of the first year of BGU is discussed
