El recorte que se seleccionó se ubica en una investigación colaborativa entre profesores de escuela secundaria y docentes-investigadores de la Universidad Pedagógica Nacional. En el transcurso de la investigación se diseñó una secuencia de actividades para la introducción al concepto de función, a partir de una situación geométrica dinámica presentada en un archivo GeoGebra. Los fenómenos estudiados en este artículo refieren a episodios que tuvieron lugar en las aulas donde se implementó. Cada episodio refiere a alumnos interactuando entre ellos y con la pantalla de la computadora en la cual están trabajando. En nuestro análisis mostraremos la mutua retroalimentación entre el contenido de la discusión que sostienen los estudiantes, las nuevas acciones que realizan en la computadora y los cambios que se producen en las representaciones en la pantalla a partir de ellas.]]></p></abstract>

The selected scope consists of a collaborative investigation between secondary school teachers and teacher-researchers of the Universidad Pedagógica Nacional. In the course of the research, a sequence of activities was designed to introduce the concept of function, based on a dynamic geometric situation presented in a GeoGebra file. The phenomena studied in this article refer to events that took place in the classrooms where it was implemented. Each event refers to students interacting with each other and with the computer screen on which they are working. In our analysis we will describe the feedback among the content of the discussion held by the students, the new actions they perform on the computer and the changes that occur in the screen representations based on them.]]></p></abstract>
