An important role of theory in research is to provide new ways of conceptualizing practical questions, essentially by transforming them into scientific problems that can be more easily delimited, typified and approached. In mathematics education, theoretical developments around 'metacognition' initially appeared in the research domain of Problem Solving closely related to the practical question of how to learn (and teach) to solve non-routine problems. This paper presents a networking method to approach a notion as 'metacognition' within a different theoretical perspective, as the one provided by the Anthropological Theory of the Didactic. Instead of trying to directly 'translate' this notion from one perspective to another, the strategy used consists in going back to the practical question that is at the origin of 'metacognition' and show how the new perspective relates this initial question to a very different kind of phenomena. The analysis is supported by an empirical study focused on a teaching proposal in grade 10 concerning the problem of comparing mobile phone tariffs. © FIZ Karlsruhe 2008.
