Challenges of a professional master's student in Mathematics Education: what my experience allows me to say

Since its creation, the professional master's degree has allowed master's students to reflect on pedagogical practice in Mathematics. In this context, this article aims to analyze the challenges of a master's student of a professional program in composing her field intervention and the resonances of this for her professionalism. To this end, the methodology is supported by a narrative perspective, in which the significant points of the master's field process are described. As a result, it can be seen that the moment of planning and the moment of application are fundamental and striking in the constitution of professionalism in a context of professional master's, allowing significant spaces for reflection and production of the identity of a researcher in his own practice. With the study, the need for professional master's degrees to trigger discussions on the training of student-teachers who attend their courses is concluded.
