ZALDIVAR ROJAS, José David  and  BRICENO SOLIS, Eduardo Carlos. What can we learn from our students? Reflections about the use of graphs. Educ. mat. [online]. 2019, vol.31, n.2, pp.212-240.  Epub June 15, 2020. ISSN 2448-8089.  https://doi.org/10.24844/em3102.09.

In this article, we present an analysis of the uses of graphs arising in an experience with Mexican high school students when they are faced to a modeling situation supported with technology. We provide accounts about both progressive and alternative redefinitions in the use of graphs during the experience, which school mathematics judge as misconceptions or conceptual mistakes. Nevertheless, under our theoretical standpoint, those uses of graphs respond to cultural forms of mathematical knowledge which are embedded in organic arguments. In that manner, we define a use of graphs’ framework where the variation, tendency and asymptotic behavior are in the core of the process of redefinition.
