editorial reviewed ; The untought materiality of digital media — in particular their environmental, social and economic implications — is raising as an issue in the fields of information and communication sciences as well as media education. In his book Mediarchy, Yves Citton takes advantage of the research carried out in the field of media archaeology to provide a more detailed understanding of the material aspects of digital devices, a.o. their persistence in the natural ecosystem (Hertz et Parikka 2012). He identifies courses of action for media education, which focus on the work of attention to be carried out by the user of digital media (Citton 2019). From another perspective, David Buckingham calls for re-thinking media literacy by considering it through a bigger picture. This shift in focus involves going beyond a list of “good digital practices” in favor of an informed understanding of the issues at stake with regard to social and political considerations. Among these is the rise of digital capitalism (Buckingham 2020) — which is obviously connected to the unlimited exploitation of material resources for profit. This proposal considers the study of a corpus of Belgian educational resource devoted to the environmental impact of digital media and technology. Using the theoretical and methodological tools of discourse analysis (knowledge discourse, rhetorical strategies for adapting to the target audience, etc.) and information and communication sciences (semiotics of screen writing, knowledge mediation, etc.), I intend to evaluate how the above concerns are, or are not, taken into account. More specifically, my analysis aims to provide answers to the following question: how (i.e., through which knowledge and competencies) do the educational resources on the environmental impact of digital technology proposed for French-speaking Belgian education aim to develop learners' digital media literacies? Our corpus will be extracted from the E-classe digital platform (https://www.e-classe.be/). Launched in 2019 at ...
