With the outbreak of the COVID-19 pandemic, the destructive harmful effects of misinformation have spread across the planet at almost the same speed as the pandemic itself. This project aims to raise students’ awareness of the dangers associated with misinformation. They will perform various activities to improve their critical thinking skills. The lack of digital competences had a negative impact on online teaching all around the world during the pandemic. Due to the enforced quarantine, students and teachers from different countries were often forced to switch to online classes. They encountered many difficulties when adapting to this situation because most of them had never used online teaching tools before. The main problems for teachers included planning online lessons, creating an interactive environment, and monitoring student progress. We believe these problems were caused primarily by a lack of digital competences, which is why the project includes activities that aim to help teachers develop their digital skills. The ITHS (Information Technology High School) and LINKgroup participate in the project together with many high schools, gymnasiums, and lyceums from Spain, Turkey, Italy, and Lithuania, thus contributing to the promotion of digital tools in education.
