Hi Emma,
I think by their very nature single-sex schools are predisposed to more overt perceptions around gender roles and that’s just the reality in a large proportion of schools in Ireland. There is however so much you can do with your all boys (or indeed all girls if that was the case) class using a debate-led approach to the topic as you’ve outlined. There is of course a bigger picture too, it’s so important at a whole school level to clearly articulate the school’s commitment to having a culture of equality and respect irrespective of the gender makeup of the school.
