  abstract     = {{In research, pedagogical content knowledge (PCK) is considered as an important aspect of teachers’ professional competence. However, there is no standardized definition concerning the internal structure of this concept, especially in science subjects such as physics. Therefore, results of different empirical studies measuring PCK are difficult to compare. Moreover, there is no study that can report on correlations between various aspects of PCK. Against this background, different conceptualizations and theoretical considerations of PCK have been consulted and compared. Based on these analyses, a comprehensive model of prospective physics teachers’ PCK and a related test instrument (in the form of a pen-and-paper test) have been developed. Its purpose is to enlighten the correlations between certain aspects of PCK as well as between PCK and other areas of knowledge (e.g. content knowledge). To validate the test instrument and the underlying PCK model, a think aloud study with 15 probands was conducted. We focused on the knowledge areas that the probands referred to while answering the items. With these data, indications of the validity of the underlying model could be identified. Furthermore, the test instrument was piloted with a sample of 216 prospective physics teachers.
