Culture and Identity is an important part of the a-level sociology specification for a number of Boards and this 30-minute film might be a good way to get your students thinking about both cultural norms generally and gender / sexual identities in particular.
The film looks at the idea of “gender neutrality” through the lens of a series of gentle interviews and observations with families and in kindergartens in Sweden, a society that has arguably gone furthest down the gender neutral route.
Although it mainly focuses on the adults and children who have, by-and-large, embraced the concept of non-binary gender, a contrary view is provided by psychiatrist David Eberhard.
The piece lends itself quite nicely to flipped teaching. Your students can watch it outside the classroom and can then be prepared for any work you decide to do on this area inside the classroom.
