Resumo
This article presents a teaching experiment in the domain of linear algebra in a context of dynamic geometry. It describes a hypothetical learning trajectory in order to construct the concept of linear dependence in terms of the mechanism of reflection on the effect-activity relationship. The results demonstrate that the simultaneous use of analytical and geometrical language, as well as the dynamic interaction with representation systems in a technological context, can encourage the generalizations required in order to develop reflexive abstraction processes that have a bearing on the creation of the concept of linear dependence.
