Primeros contactos de un grupo de docentes de escuela primaria con GeoGebra: tensiones entre conocimientos geométricos y el uso del programa

Abstract

: 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.
