EL APRENDIZAJE DE LA GEOMETRÍA A TRAVÉS DE PROGRAMAS COMPUTACIONALES

Este trabajo tiene como objetivo describir la construccion y validacion de un cuestionario para medir la motivacion de los estudiantes con respecto al empleo de programas computacionales como GeoGebra para la ensenanza de la geometria. Se realizo un analisis componencial a partir de su aplicacion a 185 estudiantes de segundo semestre de Ingenieria Agropecuaria y Tecnologias de la Informacion de la Universidad Estatal del Sur de Manabi, teniendo en cuenta cuatro factores que se consideran importantes: utilidad del programa computacional GeoGebra en la ensenanza de la geometria, no utilidad del programa computacional GeoGebra, motivacion de los estudiantes por el aprendizaje de la geometria con la utilizacion del programa computacional GeoGebra y confiabilidad de los estudiantes en el programa computacional Geogebra. Se realizo un analisis factorial exploratorio con el proposito de detectar factores comunes para formar categorias apropiadas que pudieran precisar de manera general los diferentes aspectos de las motivaciones de los estudiantes que se pretende medir. La solucion factorial inicial se llevo a cabo mediante el metodo de componentes principales y se  obtuvieron ocho factores con auto-valor mayor que uno que explicaron el 60.51% de la varianza total. Se determino el grado de homogeneidad que existe entre los elementos de la escala en conjunto, calculando el Coeficiente Alfa de Cronbach para el total de los items, el cual se  baso en elementos estandarizados, por lo que se considera que la escala tiene una buena consistencia interna permitiendo identificar que los cuatro factores del modelo, son relevantes.

A componential analysis was made from its application to 185 students of second semester of Agricultural Engineering and Information Technologies of the Southern State University of Manabi, taking into account four factors that are considered important: utility of the Geogebra computer program in the teaching of geometry, not usefulness of the computer program GeoGebra, motivation of students for the learning of geometry with the use of the computer program GeoGebra and reliability of students in the computer program GeoGebra. An exploratory factorial analysis was carried out with the purpose of detecting common factors to form appropriate categories that could specify in a general way the different aspects of the motivations of the students that it is intended to measure. The initial factorial solution was carried out by means of the principal components method and eight factors with self-value greater than one were obtained that explained 60.51% of the total variance. The degree of homogeneity that exists between the elements of the scale as a whole was determined, calculating the Cronbach's Alpha Coefficient for the total of the items, which was based on standardized elements, which is why the scale is considered to have a good consistency internal allowing to identify that the four factors of the model are relevant.
