The ERUM Open Educational Repository is a free and open collection of the study materials that have been developed in the framework of the EU-funded ERUM project. Aimed at Higher Education students from all study fields, the 15 modules listed in the Catalogue intend to provide learners with an experiential journey to deepen their knowledge about mis/disinformation, equip them with critical thinking skills to improve their resilience to “fake news”, and raise awareness about its impact on our society.
