VALBUENA-DUARTE, Sonia; TAMARA-GUTIERREZ, Yilmar  e  BERRIO-VALBUENA, Jesús D.. Technological didactic intervention for the study of conical sections based on semiotic potential. Form. Univ. [online]. 2021, vol.14, n.1, pp.181-194. ISSN 0718-5006.  http://dx.doi.org/10.4067/S0718-50062021000100181.

The objective of the present study was to identify, analyze, and characterize semiotic registers of conic sections by teachers in training. The methodology used a mixed approach based on didactic engineering. The quasi-experiment was developed in three phases: 1) preliminary analysis of conceptions and forms of teaching, 2) a priori design and implementation of educational digital resources, and 3) a posteriori analysis. The results showed learning and teaching difficulties, especially in the cognitive conversion activity. A technological didactic intervention was designed and implemented based on an open access digital educational resource supported by Duval's semiotic representation theory of registers. It is concluded that the resource is a mediator for the study of conics and the acquisition of new knowledge that allows the mobilization of mathematical knowledge from perspectives other than graphic approach or common language.
