The objectives of the project PROOF were to introduce to the young people the reality of the fake news with the focus on the social media.We split our exchange into three parts - find, evaluate and fight. With this connected the participants were asked to analyze the problems and potential consequences associated with the spread of fake news and also to identify and evaluate ways to avoid fake news in social settings. Fake news is no longer a matter of the occasional hoax. There is growing evidence that fake news has the power to shape public opinion and even sway elections. As more young people get their news online, it is increasingly vital that young people know how to verify sources and spot fake news or images, which often appear indistinguishable from a reliable source. This training ask participants to analyze the consequences of fake news and build the skills needed to question and verify what they view online.
