In this work, results of a research are presented that aim to analyze how teachers in continuous formation, participants in the discipline of Fundamentals of Differential and Integral Calculus of a Master course in Mathematics Teaching, interpret and relate the information explained by the different representations of the concept of rate of variation. For this, a sequence of activities was applied on the different representations of the concept of rate of variation and the answers of the questions were analyzed and categorized. The results show that, although they have worked on the concept of rate of variation in their undergraduate courses in Mathematics, some teachers still find it difficult to understand this concept and to relate their different representations. By analyzing the data, it is considered that the proposed activities provided the evolution of the intuitive idea of rate of variation and favored the understanding of this concept by the research participants.
