The aim of this narrative research was to investigate the process of (re)construction and management of Mathematics and Didactic Organizations in the study of logarithmic functions seeked by two environments. This process is, according to the Internal Didactic Transposition, divided into two parts. In the first, characterized by the construction of the text Know, it is exposed the factors that influenced the construction of the Didactic Organization of my proposal; the second, scored by putting into action these Praxeologies , thus building Mathematics Organization in which I reflect on the Didactic Organization and seek to rebuild it. I conducted a study related to logarithmic functions , with students of the last year of high school from a private school , which consisted in facing a task in two environments : the paper and pencil and computerized . Analyzing the results I realized the computerized environment, by providing the interaction of students with the computational model of logarithmic functions, promoted on one hand, favorable conditions for learning and the other generated restrictions, problems that indicated the need to (re)constructions of Mathematics and Didactic Organizations. The theory that allowed my analysis were the Anthropological Theory of Didactics, more precisely around the notions of Internal Didactic Transposition, Praxeologies, Conditions and Restrictions.
