ITZCOVICH, Horacio  y  MURUA, Rodolfo. First contacts of a group of primary school teachers with GeoGebra: tensions between geometric knowledge and the use of the program. Educ. mat. [online]. 2022, vol.34, n.3, pp.329-351.  Epub 17-Mar-2023. ISSN 2448-8089.  https://doi.org/10.24844/em3403.12.

This work focuses on the analysis of the productions -resolutions and discussions- of a group of 18 primary school teachers in the framework of an education Seminar on geometry didactics, which includes the use of a dynamic geometry program. The debates manifested in the first classes are shared and analyzed by establishing relationships between procedures that teachers usually put into play in a pencil and paper environment with those deployed when using said software. We ’ve tried to account for the tensions that occurred when including the “dragging” of the elements of a drawing made with GeoGebra, as part of the new working conditions. We warn about the need to generate a space for negotiation in the classroom in relation to the movement of the drawings and also about how to approach the notion of “drag” from the productions of the students.
