BARROSO, Ricardo  y  MARTEL, José. Caracterización geométrica del desarrollo de la triada piagetiana. Educ. mat [online]. 2008, vol.20, n.1, pp. 89-102. ISSN 1665-5826.

In this paper we show how the theory by Jean Piaget and Rolando García, which was developed in Psychogenesis and History of Science (1982), can be interpreted from a practical perspective and context used in geometry. We make a characterization of the triad from the literature review, according to the work of various researchers, performing a particular case of geometry. We characterize the development of a scheme "geometric problem solving". With two examples of problems with different levels of difficulty, we discusse various strategies resolution that can be considered in each of the three modes of development of thought (intra-inter-trans) proposed by these authors.
