This research aims to analyze utterances related to the role of the teacher who develops Mathematical Modelling activities, in order to discuss some conditions that allowed the construction of a pedagogical truth about the teacher. On these grounds Mathematical Modelling, in Mathematical Education, was considered from a discursive perspective, and the theorizations of the philosopher Michel Foucault used as theoreticalmethodological basis, mainly the methodological tools such as discourse and utterance. The analytical material covers theses and dissertations defended from 1987 to 2016 that report, discuss, problematize the development and application of classroom Modelling activities in Elementary and secondary School. Examination of the analytical material showed the emergence of four utterances regarding the teacher who develops Modelling activities: the teacher, when developing Modelling activities, ceases to be a transmitter and becomes a guide-mediator in the teaching process; the teacher who develops Modelling needs to master it, study it, prepare to implement it, and know the mathematical discipline; The teacher, by developing Modelling, would enable the creation of an environment of freedom, creativity, autonomy, encouraging reflection; The teacher experiences difficulty and insecurity when developing Modelling activities. The analysis was developed on the statement “The teacher, when developing Modelling activities, ceases to be a transmitter and becomes a guide-mediator in the teaching process” since its understood that the other mapped statements are characterized each as a branch, a derivation of the change of attitude of the teacher, that is, from transmitter to mediator, characterizing itself as a nuclear utterance. From the analysis undertaken we analyze the transformations, the changes that occurred in the discourses - more specifically the pedagogical - and which operated for the establishment of the practice of mediation as a pedagogical truth in the field of Mathematical Modelling. In this process we realize that the deweyano pedagogical discourse, the discourse for a new school and the constructivist speech operated for the emergence of the practice of mediation associated with the teaching figure, so that they intertwine with the discourse of Modelling itself, even operating to its own constitution. Finally, the analysis gives visibility to the discourse of Modelling while a mechanism that operates in the crystallization of the representation of the figure of the mediator teacher in the educational field.
