"Escritura" y "lectura" de gráficas cartesianas en un ambiente digital.

Language plays a key role in learning mathematics. In this particular case, we cannot speak of a single language, as there are multiple languages for this science. The graphics are artifacts digital Cartesian mediation in the process of appropriation of mathematical concepts. The study writing and "reading" of Cartesian graphs in a digital environment was conducted with students from the Industrial Maintenance in East Technological University (UTO). Participating students watched as the image of his "walk" projected through the motion sensor and a computer as mediators cast a Cartesian graph. Students found that the rate has a direct relationship with the inclination, ie, mediation between the motion sensor and the computer gives us an exercise of "reading" and "writing", which allows students to recognize and relate graphical representation characteristics of the movement, as if the student "writes" the features of its speed, its movement through digital technology; or if the student made a "reading" of understanding of the image through the Cartesian graph.
