In this course we analyzed some characteristics of constructivist approaches to learning of mathematics. Also we discuss character of digital technologies as mediation tools.

In this presentation I discuss the role of semiotic representations in the construction of mathematical knowledge

IN this course we analized some relationships between learning and cognitive development, based on the construct of mediates action.

In this course we analyzed some characteristics of instrumental mediation construct, mainly we focus our attention in the role an effect of this construct on learning of mathematics.

In this course we analyzed the interaction between problem solving learning approaches and the development of mathematical competences.

In this presentation I discuss the role of digital technologies within a constructivist approach to mathematical learning.
