Technology as a support in the development of didactic activities for covariational reasoning

Résumé

This article presents a project that promotes covariational reasoning with the support of technology in secondary school students (14-15 years old) in the case of Mexico. A didactic sequence was carried out in which exploration and guided learning sheets were designed with their respective virtual didactic environments to develop the concepts of variation and covariation from an interactive and qualitative approach to describe how one quantity varies about another. This sequence was organised through a hypothetical learning trajectory. The levels of covariation proposed by Carlson and colleagues were applied to assess the degree of development of variational thinking. The interactive virtual learning scenarios played a central role in the design of the activities and, in turn, fostered an environment of cooperation and enthusiasm in the students, allowing them to move from the context situation to the various representations; however, due to the lack of mathematical prerequisites, the students progressed only up to level 2 of covariational reasoning.
