Most of today’s communication takes place online. In the modern world digital artefacts and online practices penetrate a major portion of our everyday organisational, social and economic activities. Online communication is a big part of our lives: work and private, and it sometimes results in aggravation of the problems existing in real-life communication. One of the gravest and the most widespread of such problems that concerns modern-day youth is the so-called cyberbullying. Cyberbullying is the use of digital-communication tools (such as the Internet and mobile phones) to make another person feel angry, sad or scared, usually again and again. Examples of cyberbullying include sending hurtful texts or instant messages, posting embarrassing photos or videos on social media and spreading mean rumours online or with mobile phones and other devices. And this is a challenge people should take as seriously as they take real-life bullying. Young adults, those 18-29, are more likely than any other demographic group to experience online harassment. Fully 65% of young internet users have been the target of cyberbullying. Among those who refer to the age group of 18-24, the proportion is 70%. Young women, 18-24, experience certain severe types of harassment at disproportionately high levels: 26% of these young women have been stalked online, and 25% were the target of online sexual harassment. In addition, they do not escape the heightened rates of physical threats and sustained harassment common to their male peers and young people in general (https://www.pewresearch.org/internet/2014/10/22/online-harassment/). Being naturally concerned about their safety on the web, the active young people who had taken part in IT-related project implemented by our partnership came up with the initiative to hold another cyberworld-based project dealing with the challenges young people may face in the Net, such as cyberbullying. The aim of this project was to exchange and develop best practices of using the peer education concept in order to prevent cyberbullying and help youngsters to protect themselves if they face such challenge online. The objectives of our project were: - to familiarise the participants with the notion of cyberbullying and its types - to find out different ways of preventing cyberbullying - to define what peer education can do to support a young person who faces cyberbullying - to introduce liaison practices with adults and disseminate information about online bullying practices - to identify, present and multiply good practice examples on helping young people overcome their online issues threatening their real life - to equip the participants with empowerment skills which will enable them to share their knowledge and digital competence with their peers - to get to know the existing contemporary technologies and regulations on personal data protection - to help young people understand how they can contribute to their own well-being and well-being of their peers Since this was the young people’s idea, they were involved at every level from the preparation, implementation and evaluation phases of the project. Their participation was needed to increase motivation and "buy-in" for the project and its sustainability.
