The project aims at preventing cyber GBV through the development of ON-OFF Model with activities concerning underlying determinants, offline effects, targeted behaviours and positive social values. The Model will thus educate, raise awareness and empower teachers/educators and young people through effectively engaging Intervention Strategies. The project will also assess how it will change social attitude and involve decision-makers to promote more effective policies. The first ON-OFF target groups is teachers/educators, as professionals involved in educating children to respect everyone, overcome stereotypes, and possibly support in case of (cyber) GBV. Improving their competences means increased opportunity to sensitize thousands of young people, really contributing to violence prevention. The second target group is young people aged 12-17: they are mature enough to deal with project topics (with different levels of sensitiveness) and are particularly affected by the problem. Decision-makers will also be actively involved, encouraging their deeper commitment to ON-OFF topics, promoting project sustainability, follow-up and/or extension.
