LEON-SALINAS, Carlos Eduardo. Covariational Thinking and GeoGebra: Tools for Scientific Explanation of Certain Realities. Rev. Fac. Cienc. Tecnol. [online]. 2017, n.42, pp.159-171. ISSN 0121-3814.

This paper presents the progress of the research project titled "Variational thinking laboratory: An experience for students from vulnerable populations," which aims to design a science laboratory where the use of covariational thinking in experimental practices that promote group work and coexistence with students from vulnerable populations is analyzed. The theoretical approach of the project is socio-epistemological theory, which is an emerging theory in mathematics education and relevant to the realities of our educational community. The population chosen was Los Pinos School in Los Laches neighborhood in Bogotá. The laboratory is understood as a scenario that fosters teamwork and facilitates the use of mathematical knowledge in physical experimentation scenarios. The purpose is to support experimental work with the use of technological tools that allow students to develop skills related to computer-assisted learning, in this case, the GeoGebra software. Using this program will give the students the chance to graphically analyze the covariation of some magnitudes defined by the need to solve problems of the daily life of the members of the laboratory.

Keywords : Variational thinking; GeoGebra; socio-epistemology; vulnerable population.
