Although university mathematics teachers have an influential role on developing culture of teaching-learning mathematics in society, little is known about which kinds of teaching knowledge a future university mathematics teacher should have. Pedagogical content knowledge (PCK) provided a suitable theoretical base to study university mathematics teaching knowledge. This study aimed to find out what pedagogical content knowledge (PCK) in context of university mathematics teaching means. To answer this question, this research has done through grounded theory. Data were gathered by interviews from 27 university mathematics teachers and analysed through coding and categorizing. Data analysis revealed a detailed model which described PCK in context of university mathematics teaching.
