Interrelations among Mathematical Domains: the integration of NAG into an alternative praxeological model

Abstract

In this paper, which objective is to discuss the conditions of implementation of an alternative praxeological model – APM, based on interrelationships between mathematical domains, we present epistemological-historical aspects of three major mathematical domains, and some basic notions of didactics anthropology, to subsequent presentation of characteristics of an MPA. A cut is made for three mathematical domains, namely: numeric-algebraic and geometric – NAG. We consider these NAG interrelationships by using them in two task examples. The study under discussion is an offshoot of an investigation into interrelationships between mathematical domains in the re (construction) of praxeological models. The method was inspired by the praxeological analysis, notion of the Anthropological Theory of Didactics proposed by Yves Chevallard. The APM-NAG proposition is viable in institutional practices if attention is given to the type of task to be proposed, which places it at the center of the discussion of alternative praxeological models as opposed to dominant ones.
