Uso de Khan Academy para apoyar el proceso de enseñanza aprendizaje de Preálgebra

Abstract

The purpose of this research work, was to use Khan Academy as a strategy for reinforcement in prealgebra aimed at sixth grade students from the Western Major School of Facatativá. It is essential to strengthen the arithmetic bases necessary to make an adequate transition from arithmetic to algebraic lenguage. According to the programming in the institution´s curriculum, it was possible to work on this content in the fourth period. Seventeen sixth grade high school students took part in this investigation, who took part of the prealgebra module offered by Khan Academy, it contains 10 topics are arithmetic properties, factors and multiples, reading and interpreting data, measurement, fractions, decimals, negative numbers in the coordinate plane, ratios, rates and proportions, equations, expressions, inequalities, exponents, radicals, and scientific notation. It was possible to show, during the work on the reinforcements, that the students presented difficulties in some contents, such as measurement, factors, multiples, rates and proportions, for that reason we worked rigorously to strengthen this knowledge, also giving importance to the perception of the student on the use of digital tools for their learning.
