SALAS RUEDA, Ricardo Adán. Use of the GeoGebra cloud service during the teaching-learning process on mathematics. RIDE. Rev. Iberoam. Investig. Desarro. Educ [online]. 2018, vol.8, n.16, pp.23-52. ISSN 2007-7467.  https://doi.org/10.23913/ride.v8i16.331.

Universities have the opportunity to modify the didactic strategies and educational methods through Information and Communication Technologies (ICT). In particular, the cloud service is transforming the interaction between the participants in the teaching-learning process during the 21st Century because the access, storage and distribution of information take place from any place. Also, students do not need to install any program on the computers and mobile devices to use the service in the cloud. The purpose of this quantitative research is to analyze the impact of the GeoGebra cloud service in the didactic unit Linear inequalities. The sample is composed of 78 students who took the Intermediate Mathematics for business course during the 2017, 2016 and 2015 school cycles. The experimental group (31 students) carried out four laboratory practices on the topics of Linear inequality, Linear inequality system, Objective function and Applications of Inequalities through the GeoGebra cloud service. The obtained results allow affirming that GeoGebra is a useful and easy application to graph the functions, identify the regions and coordinates in the graph, recognize the solution region and assimilate the knowledge on the subjects of algebra. Even students are satisfied to use this technological tool in the Didactic Unit Linear Inequalities. Likewise, the ANOVA method with significance levels 0.05 and 0.03 confirms that the GeoGebra cloud service improves students' academic performance. In conclusion, GeoGebra represents an innovative, creative and useful tool for the area of mathematics.
