This work is part PhD thesis whose objective is that pre-service physics teachers can build or strengthen (at least part of) a Pedagogical Content Knowledge (PCK) in an electromagnetic course. For this purpose, an electromagnetic course was reconstructed based on science education research results that promotes the productive disciplinary involvement of students. We characterize PCK about electric circuits of two students who have taken this reconstructed electromagnetic course. At the same time, the PCK of another student who has taken the electromagnetic course but before it was reconstructed is characterized as well. For the characterization of the PCK, each of the three students involved in this study is asked to elaborate a sequence of activities of two classes on electric circuits and each component of the PCK is analyzed on the basis of a rubric designed for this purpose. The analysis shows that the PCK corresponds to teachers in training, although there are differences among them. The students who took the reconstructed course have a more developed PCK on electric circuits compared to those who took the same course before its reconstruction.
