• Using multiple representations and changing between them is at the heart of the mathematics classroom; unconnected changes can, however, be obstructive for students' learning. In order to support students' learning with multiple representations, teachers have to link observed situation aspects with relevant professional knowledge, a competence we described as teachers' analysing of classroom situations in prior research. Although teachers' professional knowledge plays a critical role in such competence, empirical evidence regarding different facets of such knowledge and their interplay is still scarce. This study investigates different facets of teachers' knowledge of using multiple representations in the context of learning fractions and their role for teachers' corresponding competence of analysing. We asked N = 298 teachers at different levels of expertise to analyse six classroom situations presented as text, comic or video. Our findings indicate that knowledge facets related to mathematical content are significant predictors for teachers' competence of analysing.
