This paper aims to present a reflection about the learning process of Exponential Function in High School, from the employment of the virtual game Tower of Hanoi through the use of educational laptops. The data were collected by an initial questionnaire, in order to identify the preliminary ideas and to register in a field journal. After the data were analyzed according to the Discursive Textual Analysis. From this analysis two categories emerged: the first indicates that the initial idea which the students presented in relation to the Exponential Function is associated to a characterization of the language to the Quadratic Function. The second category points a transformation of the natural language understanding of Exponential Function to the formal language, that is to say, the formal school concept of Exponential Function.
