INVESTIGATING COGNITIVE EFFECTS ON STUDENTS IN TEACHING POLINOMIAL FUNCTION INSTITUTED IN GEOGEBRA IN COLLABORATIVE ACTIVITIES SUPPORTED IN THEORY OF ACTIVITY
Polynomial function; Geogebra; Activity theory
We identified throughout our performance, both in the higher education classroom and in our research, that students have difficulties in understanding the representation of graphs, among other conceptual elements of a polynomial function in the teaching and learning process, in the subjects. In some cases, we find that students have not developed sufficient skills to construct and analyze the graphical representation of the polynomial function and the mathematical concepts involved in this content. We observed in our classes, by experience in teaching practice in higher teaching that is common among students have difficulty understanding and analyzing the various models of representation of the polynomial function.
