Momentos de exploración e ilustración en la determinación de circunferencias en futuros docentes de educación secundaria

Trabajo realizado en el marco del proyecto EDU2017–84979–R, del Programa Estatal de I+D+i Orientada a los Retos de la Sociedad.

Abstract

In Master’s degree in Secondary Education Teaching, speciality in mathematics, the activity of students in a didactic situation for the study of circumferences is analyzed. The activities made by the students follow an explorative and illustrative methodology to study the analytic geometry methods to represent circumferences and the characteristics of these figures. The first step is to identify the previous knowledge of the students and then, give them learning tools in different formats to consolidate and develop this knowledge. The study process evolves through the interaction of two material tools: one, the dynamic software GeoGebra; and other, the «pencil and paper». Conclusions are drawn about the importance of the interaction between the tools in the acquisition of knowledge and its involvement in the planned teaching interventions.
