SANCHEZ LUJAN, Bertha Ivonne  e  CAMACHO RIOS, Alberto. NUEVOS OBJETOS Y NUEVAS TÉCNICAS PARA LA ENSEÑANZA DE LA MATEMÁTICA. Rev. Esc. Cienc. Educ. [online]. 2017, vol.1, n.12, pp.115-131. ISSN 1851-6297.

This paper presents a study toward the transposition of a concept to mathematics praxeologies. The concept is clear of external technologies to the praxeologies, highlighting and an episode of confrontation of practical knowledge that occurs when attempting to legitimize the different techniques that immersion implies. Ambiguities and epistemological ruptures arise from said confrontation, and give rise to incorporate practical technologies for the validation of the techniques, since the model praxeological does not respond to the level of empiricism outcome of the activity. The main objective is to highlight the lack of justification of techniques that are external to the mathematical practice which are transposed to resolve certain tasks T and, furthermore, how this lack of justification makes necessary other technological arguments in the Anthropological Theory of Didactics for its own justification.
