She says that she has experienced a lot of fake news when surfng the Internet. At school they learned about how to identify fake news, but it was ‘out of touch because as a younger generation we know that fake news exists and we know to be critical of the things we read’. This short example should depict the problem we would like to address in this chapter, namely: what kind of digital competences young people should acquire at school, in particular when they are or will be faced with fake news. Fake news is not a new phenomenon, but it has become increasingly diffcult to distinguish between correct, erroneous, and deliberately falsifed information (Auberry 2018), and the debates about the magnitude of this problem amongst media industry, politics, and academia have increased (Lazer et al. 2018). Around two-thirds of students, rate news reports in social media as credible, and an increas- ing amount of fake news is interpreted as fact (Himmelrath and Egbers 2018). It seems therefore necessary to better understand young people’s postdigital practices. For this reason, we asked students to show us their online performances (Goffman 1959). This approach should help us gain a better understanding of young people’s online practices and sharpen our suggestion of what kind of competences are needed to obtain critical digital literacies (Davies 2018).
