Ib this article co-authored with colleagues we discuss the phenomenon of what we call ‘edwashing’. On the Apple App Store or Google Play Store, parents can choose from a dazzling number of ‘edutainment apps’ that claim to teach children essential skills whilst also being ‘fun’ and ‘engaging’. In this article, we introduce the phenomenon of ‘eduwashing’ by showing the variety of semantic strategies used by app developers to ‘produce’ educational legitimacy. Taking the popular app Lingokids as a case study, we identify the following three dimensions of eduwashing: edubranding, educlaiming and educertifying. Edubranding involves the use of educational trend words and the appropriation of well-established educational brands. Educlaiming involves the commission of research by developers and the blurring of positivist language with the hyperboles of commercial advertising. Lastly, educertifying involves the use of labels, award and certifications. We conclude by arguing that eduwashing practices make it increasingly difficult for educators and parents to assess the educational relevance of children’s apps.
