This research concerns initial formation (DeBlois, 2012; DeBlois & Squalli, 2002) for the context of the documentary genesis (Gueudet & Trouche, 2010) of the teaching project of Christelle, a preservice teacher of mathematic. She was invited to explore a directory of digital documents in order to improve statistical contents of the Cameroonian textbooks, in particular the standard deviation. We observed how this preservice teacher moved from documentary resources to documents containing to involve documentary genesis. Thus, this article presents the variables of arrangement, particularly the way in which she introduces her planning of the teaching of the standard deviation, the manner in which she recognizes students’ interest, the modifications she does in the contents of the documents she exploited.
