PASSOS SA, Luciana  y  GARRITZ, Andoni. Pedagogical Knowledge on "Nature of Matter" of Brazilian scholars of a pre-service program. Educ. quím [online]. 2014, vol.25, n.3, pp.363-379. ISSN 0187-893X.

Pre-service and in-service teachers' training has been the focus of several programs developed in Brazil. Among them, the called "Institutional Program of Teaching Training Scholarship" (in Portuguese "Programa Institucional de Bolsa de Iniciação à Docência-PIBID") is really remarkable, which has as its main goal improving the academic actions for pre-service teachers training. This study has the aim to analyze the transformation of knowledge and beliefs of future chemistry teachers -scholarship holders of PIBID- on the topic "Nature of Matter", to make it comprehensible to high school students. That is, documenting and discussing the development of Pedagogical Content Knowledge (PCK) of each one of these scholars during the design and application of a didactic unit on the topic. The research was done with four scholars of the Program, students of a chemistry career in a public Brazilian University. Two elements were considered to show the improvements of the participants PCK: an initial interview in which the eight questions of the Content Representation of Loughran et al. (2004) were posed, and afterwards the Didactic Unit produced and applied to high school students. Main results show the appropriation for students of enough knowledge for the adequate performance in the classroom, it stimulated by the actions PIBID contemplates.
