In 2019, UNESCO enabled Open Educational Resources to become a shared goal of the international community, by having its Recommendation adopted. Among the authors of the twenty-three reasons, several participated in the work leading up to this essential document, and some hold UNESCO Chairs whose subject is open education. It is therefore with pleasure that we welcome Zeynep Varoglu, who has been the key person coordinating, at UNESCO, the efforts on OER. Zeynep has agreed to share her global analysis and views on the new context, favourable to the development of open education. In a way, Zeynep is telling us why… it’s the right time to open up!
