Didactics on Knowledge: a Road to the Optimization of Didactic Transpositions

Abstract

Worried about the quality of education and within the framework of the Theory of Didactical Situations in Mathematics (Brousseau, 1998), and particularly in the anthropological approach proposed by Yves Chevallard (1991), this paper presents a tool that, in its first place, aims at optimizing the process of didactic transpositions, through the definition of a distance between the knowing how to teach and the knowledge learned (Mabille & Albert, 1994), by proposing the knowledge to be a multidimensional being and each one of these dimensions to be independent from each other. On the other hand, the definition of distance is structured according to a stochastic conception, using the logistic function to model the probability of emitting a correct answer to stimulus acting on the knowledge learned.
