“…We analyse the contradictions and ambiguities that emerged from the collected data, since we were able to identify traces of some of the tensions referred to above. Drawing upon recent research in the fields of teachers' professional identity (Thomas & Beauchamp, 2011;Jephcote & Salisbury, 2009;Hall & Noyes, 2009;Flores & Day, 2006), the epistemology of practice and reflexivity (Schön, 1983(Schön, , 1987Geerink, Masschelein, & Simons, 2010;Fendler, 2003), teachers' beliefs (Alger, 2009) and the cultural narratives of teaching and learning (Davis, 2004;Davis, Sumara, & Iftody, 2008), we analysed the collected data in order to highlight some ambiguities and to problematise their implications for research about teaching and teachers' beliefs. We understand that, in some cases, the ambiguities and contradictions which we detected express what we have called aporias 1 of teaching as a profession: these aporias represent ambiguities in the construction of teachers' identity but also emergent possibilities for the current understanding of teaching and teacher identity.…”
