This study follows a methodological approach of a qualitative type, comprising case study, with recourse to interviews, participant observation and documental analysis. A first analysis of the written reflection of one of the participants, included in the reflection portfolio, points, in terms of content, towards less spreading of the themes approached, the ones considered the most significant being subsequently extracted and correlated. A greater depth in the reflection is also noted, with the teacher having concern to justify her statements, present a critical analysis of her role and rethink her practice.engProfessional developmentMathematics' teacherTeacher trainingReflectionPracticeconference paper
