Una aproximación a los miedos de docentes de secundaria en prácticas. Entre la reproducción y la transformación

A series of recent studies has identified as a key issue among novice teachers the tension between the adoption of institutional and standardized logics and innovation or transformation, which in turn is highly influenced by the students’ school backgrounds, traditional socio-professional settings, and the initial teacher training experience. This article proposes an in-depth understanding of this phenomenon in a case study research, from a qualitative longitudinal approach, centered on the analysis of the assumptions and attitudes that configure the teaching practices of six secondary novice teachers from different Chilean universities. In spite of the notorious differences among students, fear of changing politics is their common ground, leaving them with no choices but to obey the hegemonic power of a highly controlling and standardized education system. As a conclusion, fear is seen as a paralyzing agent that will prevent students from subverting these barriers. Unless teacher education programs do not encourage students’ raise of political, epistemological and pedagogical awareness and empowerment, they will continue struggling with their fears, and therefore they will not bring about new courses of action. Transforming reality is possible only by transforming ourselves....
