    (Universidad Privada Norbert Wiener, 2017) Rodriguez Robles, Alejandro; Fox Cortez, Julio Alonso
    The main objective of the present investigation is to verify what extent the application of the software Descartes improves the construction of the notion of fraction per the students of fourth degree of the Sede Central in the Institución Educativa Técnico Comercial Sagrado Corazón de Jesús of Chiquinquirá in the year 2016, considering the meaning of fraction as part-whole, measure and multiplicative operator. The research by its type is applied, of quasiexperimental level, of pretestpostest design with group of control equivalent, of approach or quantitative method, with sample non probabilistic equal to the totality of the population that is to say the 138 students of the four fourth grades, the groups were kept intact in order to preserve their initial equivalence, since they are not randomly assigned or matched, but that groups are already formed before the experiment (Hernández, R., Fernández, C. y Baptista, M. P., 2010), the instrument used for data collection was the questionnaire, the hypothesis test was applied for a normal distribution with a reliability level of 95% and a margin of error of 0,05. The results of the hypothesis contrasts in the input test indicated that at the beginning of the research, the performances where the construction of the notion of fraction from the meanings part, measure and multiplicative operator between the experimental and control groups were shown to be equal; and in the test of output indicated that the performances where the construction of the notion of fraction from the mentioned meanings were shown were higher where Descartes software (experimental group) was applied than where it was not applied (control group). For beafore written, it is concluded that the software Descartes improves in a statistically significant way the construction of the notion of fraction from the meanings part-all, measure and operator multiplicative per the fourth-grade students of the Education Educational in the year 2016.
