Digital platforms are increasingly shaping our pedagogic landscape. Even platforms not intended for teaching and learning are still pedagogic in that they teach us how to live and work in a platfomised society. In this chapter, I will use Bernstein’s concept of the pedagogic device to describe a shift in evaluation rules brought about by game design elements commonly used in platforms: points, badges, and leaderboards. I will argue that points and leaderboards are underpinned by a logic of quantification and popularisation teaching us how to constantly compare and evaluate ourselves on a wide variety of metrics. Badges are used as a form of deregulated qualification designating expertise through micro-skills. Points, leaderboard and badges reshape ‘traditional’ school pedagogy in two ways. First of all, they are increasingly incorporated into learning designs, exacerbating an already-existing regime of ranking and rating. Secondly, they are actively competing with the school’s ‘weaker’ qualification codes. Platforms’ evaluation regimes are often embedded into monetisation options, making them seem more relevant to young people, who now often aspire to become influencers or content creators. The ranking and rating mechanisms of platforms’ evaluation regimes make them especially vulnerable to ‘pedagogues’ spreading dis- and misinformation.
