Funzioni: un approccio dinamico

Within mathematics education, function has come to have a broader interpretation that refers not only to the formal definition, but also to the multiple ways in which functions can be written and described. Starting from Junior High School, students need to build a strong conceptual understanding of functions as well as procedural fluency. The very central concept discussed in this paper on functions is that of a dependent relationship: the value of one thing depending on, determined by, or being a function of another. The kind of problems we are dealing with no longer are focused on determining a specific value, they are focused on the process that tells us how one thing is related to another and the study of some related intrinsic properties.
