ROJAS MALDONADO, Erick Radaí. Design of opening strategy for graphic-analytical interpretation through Desmos as preparation for the learning of differential calculus. RIDE. Rev. Iberoam. Investig. Desarro. Educ [online]. 2019, vol.10, n.19, e004.  Epub 15-Maio-2020. ISSN 2007-7467.  https://doi.org/10.23913/ride.v10i19.493.

The drawing encourages the student's creativity because it allows to document information and clearly represent the understanding of abstract concepts, hence the use of the educational application Desmos, a didactic tool that can be used not only on any smartphone, but also that allows a pleasant approach of the student towards the analytical geometry. For this reason, in this project the aforementioned software has been used to contribute to the student's understanding of differential and integral calculus. The final objective was to design an opening / start activity strategy for the didactic sequence developed by Rojas Maldonado (2015), and in this way favor creativity and graphic-analytical understanding of mathematics for the learning of differential calculus and to prepare the construction of the concept of limit. This project, based on the BYOD program (Bring Your Own Device), was developed in the 2018-2019 period when the thematic unit functions in the subject of Differential Calculus was explained. The study involved 123 students from both the Bachelor of Engineering and Architecture of the Colegio Primitivo y Nacional de San Nicolás de Hidalgo and the second semester of the degree in Biotechnology, both groups belonging to the Universidad Michoacana de San Nicolás de Hidalgo. The results show that it was possible to promote a mathematical development and apply a didactic model to structural figures, which were linked to everyday situations or natural phenomena that helped to reduce the difficulties between the analytical and graphic mathematical world.
