This paper elaborates on the results of a qualitative study on heteronormativity and introduces a reflective seminar concept invented and designed for this purpose. The model aims at facilitating students' ability to reflect on heteronormativity. Challenging their thinking about heteronormative practices, we asked students to use it and thereby reflect in three consecutive steps upon the impact of heterosexuality in educational situations. The results showed a contradiction between the students’ positive attitudes towards equality and a lack of ideas of how to promote it. This indicates a lack of opportunities for students in to reflect. Addressing aspects of diversity such as sexual identities and orientations, we suggest that our reflective model is a very useful tool to promote reflective processes.
