Abstract

GeoGebra is free software of interest for teaching and learning mathematics, since it offers the possibility of associating geometric and algebraic objects to solve complex problems; It also allows the approach of various mathematical problems in a creative and original way. For this reason, this research had the objective "to identify the effect of the use of GeoGebra on the achievement of the competences of the area of mathematics in the students of the 4th grade of secondary school of the private educational institution Bertolt Brecht of Lima, 2022". Its main theoretical foundation is the focus on problem solving. It was a quantitative study, positivist paradigm, hypothetical deductive method; quasi-experimental design, longitudinal cut, with a population of 70 students, control and experimental group of 35 members each. For data collection, the survey was used by technique and the knowledge test by instrument. The main result was that in the pretest the average range of achievement of mathematical skills was similar for both the control group and the experimental group, while in the posttest the U-Mann Whitney test exhibited significant differences (11,500 and z= -7 .09), with a ρ= .000. It is concluded that the use of GeoGebra influences the achievement of mathematical skills in the studied sample.
