La caja decimal y el aprendizaje de la matemática en cuarto grado de la Unidad Educativa “19 de Septiembre”

Abstract

The present research is focused on the importance that the use of the decimal box has for children, since through the visualization and manipulation of objects they are able to internalize concepts and achieve meaningful and active learning. The topic is current because, although technology continues to advance, the use of concrete materials remains indispensable in the classroom. Therefore, the objective of the study was to analyze the impact of the decimal box on mathematics learning in fourth-grade students at the “19 de septiembre” Educational Unit. The methodology applied had a mixed approach, at an applied level, with a quasi-experimental design, bibliographic and field modalities, and the population consisted of 119 children, from which an intentional sample of 78 students was selected, divided into two groups: an experimental group and a control group—parallel “A,” made up of 38 children, and parallel “B,” with 40 children, respectively. The research was framed within the line of Social and Educational Behavior. It is concluded that the experimental group reached an average of 8/10 points after the intervention with the decimal box, whereas the control group reached an average of 6/10 when continuing to work in a traditional manner. According to the data mentioned, there is a mean difference of 2 points between the groups. Thus, the hypothesis demonstrated that the application of the decimal box improved Mathematics learning, since the p-value was < 0.05.
