A trajetória das Diretrizes Curriculares Nacionais para a formação docente no Brasil: uma análise dos textos oficiais

The article analyzes the trajectory of the Diretrizes Curriculares Nacionais (DCN, 2002; 2015; 2019) in Brazil along a cycle circumscribed by five governments (Fernando Henrique Cardoso, Luis Inacio Lula da Silva, Dilma Rousseff, Michel Temer and Jair Bolsonaro). The documents were encoded based on four dimensions; (i) motivation and participation, (ii) guidelines for the temporality and structure of the courses, (iii) teaching professionalism and (iv) professional development. By articulating the official texts over almost 20 years, the analyzes reconstruct its trajectory in the field of teacher education, marked by advances, setbacks and ruptures. Between 2002 and 2015, the DCN emphasizes more critical training, combining initial and continuing training, in addition to professional development. The post-coup of 2016 reveals a worsening of the process of devaluation and weakening of the professional status of teaching, manifested in the DCN/2019.
