“…as dynamic objects that respond to algebraic tools and that are present in situations involving functional relationships. There are registers of the difficulties that arise in students when these reasoning processes do not reach the expected scope, as in the learning of functions (Bagossi et al, 2022;Rolfes et al, 2021;Thompson & Carlson, 2017). These difficulties, research is directed in principle to the study of covariation and the student's level of reasoning, in pre-class stages on the elaboration of planning or with the analysis of introductory tasks and instructions in basic level (primary and secondary), even with the instructional strategies that the teacher uses to facilitate reasoning, in post-class stages with the analysis of the construction of mental images obtained from dynamic situations and the ratio between covariate quantities (Castillo-Garsow, 2012;Johnson, 2015a;Miranda & Sánchez, 2019;Oehrtman et al, 2008;Panorkou & Maloney, 2016;Passaro, 2009;Swidan et al, 2022).…”
