Digitization is finding its way into almost all areas of life and all over the world. One of the biggest disruptive changes took place and is taking place in the media sector. 20 years ago, print and TV media reached most people, but their reach is now far surpassed by social media. Facebook reaches around 2.7 million users worldwide who produce, consume and evaluate information. The flow of information is often guided by algorithms according to the user's interests, but without giving them a choice. This can lead to users finding themselves in so-called filter bubbles or echo chambers and only receiving messages and information that correspond to their own attitude. The same applies to advertising, which is becoming more and more personalized as more data becomes available. Misuse of social media by social bots and fake news also poses a great risk. A lack of media competence therefore poses a great danger to democracy as a whole, but also to the education of individuals. The aim of the project was therefore to raise awareness of the dangers of big data, filter bubbles and fake news and at the same time to encourage people to critically question their own media behavior. At the same time, we also wanted to show the opportunities of digitization. The students get to know various digital collaborative learning and working tools, create and learn to distribute digital content effectively. They were shown how new media can be used to get involved as a citizen. The program included numerous talks with experts from the print and online media scene, as well as visits to state institutions. With a large variety of methods (workshops, discussions, scenario techniques, interviews, role plays) and a varied supporting program, a project is being developed that consists of encounters in Hamburg and Olsztyn that build on each other. Project results are made available digitally as a website and in social media, and dissemination plans are developed so that the project has the greatest possible reach. After a joint implementation of the 2 encounters, the planned further encounters could not take place. The exchange between Poland and Germany on this topic is particularly suitable. While Poland is a rather homogenous country that has recently taken on strong autocratic traits, where the merging of media and state power is taken for granted, in Germany media and state power are largely disentangled. In the field of social media, however, the countries and thus the participating students face similar dangers. With this project, we wanted to develop information and media skills and promote active civic engagement. In order for the EU to exist, it needs open, tolerant people who carry the spirit of European unity, diversity and togetherness and are willing to pass this on to future generations.
