Addressing sexting in sexual health education classrooms is one way of supporting young people to become good sexual citizens and to emphasise respect and consent in their sexual practices and in their lives. While a fair amount of research has worked with youth to understand their motivations for sexting, less research has been conducted with in-service teachers to understand their perspectives, pedagogical approaches, and beliefs regarding young people and sexting. Set in this context, this paper discusses findings from interviews with Canadian teachers who were teaching a new Ontario Health and Physical Education curriculum that included discussions of sexting. Our findings suggest that many teachers are still engaging discourses of risk, shame and blame when they talk to their students about sexting. Likewise, longstanding gender norms and stereotypical sexual scripts are evident in the ways in which many teachers both understand and teach sexting. Some teachers, however, are engaging in more promising pedagogical practices that frame sexting as having a range of uses, outcomes, and purposes, painting a more holistic picture of young people's sexting landscapes. Findings from this paper may be useful for educators and policymakers creating sexting curriculum for young people in educational settings.
