Abstract
Este trabajo de investigación tuvo como objetivo mejorar las competencias
matemáticas en los sistemas de ecuaciones lineales de dos variables de los estudiantes del
curso de Nivelación de matemáticas. La mayoría de estudiantes tienen dificultades para
representar gráficamente la ecuación de la recta, así como representar gráficamente un
sistema de ecuaciones lineales de dos variables en el plano cartesiano, también presentan
deficiencias en resolver un sistema de ecuaciones lineales de dos variables y en modelar
matemáticamente problemas de contexto real. La calculadora online desmos facilita el
logro de competencias matemáticas ya que es una plataforma de fácil acceso y se puede
manipular de una forma interactiva para representar gráficamente cualquier ecuación
algebraica. Esta tesis tiene como objetivo probar el uso de la calculadora online desmos en
los estudiantes de la Universidad Peruana de Ciencias Aplicadas en el curso de Nivelación
de Matemáticas, en particular, en el estudio de los sistemas de ecuaciones lineales de dos
variables, que es tema básico e importante para comprender y resolver problemas de
contexto real. Para el estudio se consideró un grupo control de 25 estudiantes y otro grupo
experimental de 25 estudiantes los cuales fueron medidos con un instrumento en el pre-test
y pos-test. La prueba de hipótesis se realizó a través de hipótesis para la diferencia entre
medias poblacionales normales y el estadístico de prueba que se utilizó fue la distribución t
de Student.
This research work was to improve mathematical skills in the two-variable linear equation systems of students in the Mathematics Levelling course. Most students have difficulties in graphically representing the line equation as well as graphically representing a two-variable linear equation system in the Cartesian plane, they also have deficiencies in solving a two-variable linear equation system and in mathematically modeling real context problems. The desmos online calculator facilitates the achievement of mathematical skills since it is an easily accessible platform and can be manipulated in an interactive way to graphically represent any algebraic equation. This thesis aims to test the use of the desmos online calculator in the students of the Universidad Peruana de Ciencias Aplicadas in the Mathematics Levelling course, in particular, in the study of two-variable linear equation systems, which is a basic and important subject to understand and solve real context problems. For the study a control group of 25 students and an experimental group of 25 students were considered, which were measured with an instrument in the pre-test and post-test. The hypothesis test was performed through hypotheses for the difference between normal population means and the test statistic used was the Student t-distribution.
