Abstract : In view of the lack of instruments for measuring biology teachers- pedagogical content knowledge PCK, this article reports on a study about the development of PCK-items for measuring teachers- knowledge of pupils- errors and ways for dealing with them. This study investigated ninth and tenth grade German pupils- n = 461 drawings in an achievement test about the knee-jerk in biology, which were analysed by using the inductive qualitative analysis of their content. The empirical data were used for the development of the items in the PCK-test. The validation of the items was determined with think-aloud interviews of German secondary school teachers n = 5. If the item was determined, the reliability was tested by the results of German secondary school biology teachers n = 65 who took the PCK-test. The results indicated that these items are satisfactorily reliable Cronbach alpha values ranged from .60 to .67. We suggest a larger sample size and American biology teachers be used in our further studies. The findings of this study about teachers- professional knowledge from the PCK-test could provide new information about the influence of teachers- knowledge on their pupils- understanding of biology and their possible errors in learning biology.
