In teaching Calculus, some researches highlight that concepts such as slope, velocity, and rate of change are significant and useful per se, since they constitute the axial structure of the functions and the Analysis. Base on that, appear our interest on rate of change learning, because it is necessary to understand the processes that the students made to give a meaning to that concept. In regard, this qualitative research sets out to study the mathematical work of last year students of High School when they are resolving tasks related to rate of change of a real function of real variable in which it is consider rate of change (average and instantaneous) as velocity (average and instantaneous). To that end, it was designed and applied a learning situation to four students (16 - 17 years old) grouped on two binomials, of last year of High School of an educative institution on Valparaíso, Chile. For the analyses, we will use, as theoretical framework Mathematical Working Space (MWS) formulated by Kuzniak, which allows us to characterize the student's mathematical knowledge and production, as well as the epistemic and cognitive value of the tasks. Based on the results, it is evinced the activation of the different genesis of MWS and vertical planes associated to them, as well as, the analysis paradigms identification that were identified. In conclusion, students’ actions and productions concentrate on the activation and coordination of the semiotic, instrumental and discursive genesis and with it the vertical planes [Sem-Ins] and [Ins-Dis], as well as the analysis paradigms GA and CA.
