Notion of approximation of the area under the curve using the GeoGebra Graphing Calculator app. Prax. Saber [online]. 2020, vol.11, n.26, e9989.  Epub 25-Feb-2021.

This article presents the results of a research performed in the Faculty of Engineering and Basic Sciences of the Fundación Universitaria Los Libertadores, Bogotá. The objective was to describe and to analyze the effects of implementing a didactic unit intended to teach the notion of area under the curve, in the context of an integral calculus course, based on the use of smartphones during the learning experience. To this end, an experimental Solomon four-group design was carried out. The purpose was to determine the influence of an intervention mediated by the GeoGebra Graphing Calculator app and verifying the effects of a pre-test on the quantity of correct answers in the post-test. A two-way ANOVA procedure was used in order to assess the results. The findings show that the pre-test had a direct influence on the post-test results and that in the postest the two groups that received the intervention based on the GeoGebra app outperformed the groups that had an intervention with regular scientific calculator.

Palabras clave : mobile learning; area under the curve; dynamic geometry software; digital technologies.
