ABSTRACT This article describes the process of conceptualization of four groups of pupils in high school [121 students around the age of 15-16 years], and the way they study the conceptual field of the exponential functions with a dynamic of study, in which the first aim is the participation of the pupil in the construction of knowledge. What is especially used is the theoretical constructs proposed by Vergnaud´s Conceptual Fields Theory (1990, 1996, 2007a, 2007b, 2008, 2010), to describe the answers of some pupils when a problem that is solved through means of exponential models is propose. The analysis of the protocols shows a process of conceptualization, linked to the different systems of representation of the exponential function, which is possible to describe by five stages.
