This paper draws on research into male teachers in one single sex high school in the Australian context to highlight how issues of masculinity impact on their pedagogical practices and relationships with boys. The study is situated within the broader international field of research on male teachers, masculinities and schooling in Australia, the UK and the US and provides further knowledge about the gendered dimensions of male teachers' pedagogical practices in secondary schools. The authors argue for the urgent need to interrogate the impact of masculinities in male teachers' lives at school, given the call for more male role models to ameliorate the supposed feminizing and emasculating influences of schools on boys' lives. A particular Foucauldian perspective, which draws on surveillance and its key role in practices of gender subjectification, is used to provide insight into how two male teachers learn to police their masculinities and to fashion pedagogical practices under the normalizing gaze of their male students.
