Through our “SMART on Social Media” project, we aimed to contribute to the development of media literacy skills among young people we work with and to empower them to become informal educators in the field of media literacy themselves, for other young people in their communities, as well as online. This goal came as a result of many years of experience in working with young people (both ours, those from ASTRID Association, and our partners’), years during which we saw an increasing need for the implementation of such activities. Young people start using social media (sometimes only as consumers, but other times also as content creators) at a very young age, often at 9-10 years old or earlier. From our experience - and from the confirmations of several specialised studies in this field - most of the time, young people lack the necessary critical thinking skills to correctly identify fake news, disinformation and all the other dangers on social networks. They also lack knowledge about what a reliable source of information is and what double-checking information means. They cannot easily process hate speech and cyberbullying, and don’t know how to react properly to them. Media literacy is not present in the school curriculum in any of our countries as a mandatory subject, so it is absent from formal education. The initial objectives of our project were: By the end of the 7-day youth exchange, the 30 participants from 6 countries will: ● demonstrate improved media literacy skills, measured by pre- and post-mobility assessments (surveys); ● undergo a series of self-assessment sessions led by a psychotherapist, to identify the negative impact of social media on their mental health; ● produce and post on social media at least 20 videos (short format, reel-type) that address topics related to online hate and the impact of social media on young people; ● develop and implement 6 local action plans (1 / each country) to disseminate among their colleagues and friends what they have learned about media literacy and/or the impact of social media on their mental health. After Croatia withdrew from the project, we adjusted the objectives as follows: By the end of the 7-day youth exchange, the 32 participants from 5 countries will: ● demonstrate improved media literacy skills, measured by pre- and post-mobility assessment questionnaires; ● undergo a series of self-assessment sessions led by a psychotherapist, to identify the negative impact of social media on their mental health; ● produce and publish on social media at least 10 videos (short format, reel type) that address topics related to online hate and the impact of social media on young people; ● develop and implement 5 local action plans (1 / each country) to disseminate among their colleagues and friends what they have learned about media literacy and / or the impact of social media on their mental health.
