Abstract
This research aims to investigate how to promote the development of variational and covariational reasoning in students of a graduate program in Educational Mathematics. To achieve this objective, we conducted classroom design studies on container filling and designed a hypothetical learning trajectory whose goal is to promote the development of variational and covariational reasoning of the variables height and volume through measurement with rulers and syringes. Our results show that the real learning trajectory of one of the participants (Luis) confirms our learning hypothesis that the physical experience of filling containers and measuring with instruments (ruler in centimeters for length and syringe in milliliters for volume) promotes the development of variational and covariational reasoning at a continuous fragmented level.
