Diseño de enseñanza de las propiedades globales de las funciones a través de sus gráficas

In this paper we represent the teaching design of the global properties of functions through their graphics as a response to a problem of learning detected in the classroom. We have built a teaching design based on the characterization of the process of learning which offers the theoretical frame known as Logic Semiotic Focus (ELOS), which aims to facilitate the learning of such properties by means of the coordination of representation systems.
