International cooperation, digital skills and real-life learning define the European eTwinning platform, which has been part of Slovak schools for more than 20 years. To we explore how Europe’s largest online community of schools connects teachers and students across borders through projects that develop key competences for life in the 21st century we speak with Katarína Hrbáňová, coordinator of eTwinning Slovakia, the National Support Organisation based at the University of Žilina, and Ivana Bršťáková, an English teacher at Business Academy Dudova in Bratislava, who presents her award-winning project Eco-Heritage: Cultures United for Nature. The project won third place in the Slovak National eTwinning Competition 2025 in the secondary school category and brought together students from Slovakia, Spain and Turkey to explore cultural heritage, environmental protection and eco-tourism. As always, the programme includes a new edition of our language corner, Slovak Sound Check.
