Abstract

Abstract: The general objective of this research entitled Influence of the use of GeoGebra on the degree of understanding and graphical representation of linear and related functions was to analyze how this tool influences the learning of ninth grade students of General Basic Education of the Educational Institution Fray Sebastian Acosta , located in the Baños de Agua Santa canton, province of Tungurahua. This study was developed with a quantitative approach, with a quasi-experimental design, applying a pretest and posttest to a control group and an experimental group. A structured questionnaire with closed Likert-type questions was used as an instrument, elaborated according to the objectives and previously validated by experts in the area of mathematics. The results showed that the use of GeoGebra had a favorable influence on the understanding of the elements of linear and related functions, facilitating the construction of tables of values, graphical interpretation and recognition of their components. However, a group of students was identified that still presents difficulties, so it is suggested to complement its use with other pedagogical strategies.
