New strategies are required to create a European society active at all ages. These must enable elders and youngsters to be protagonists in the social life of their communities. New forms of volunteering provide a major opportunity for this to happen, enhancing the self-esteem of both generations while reducing the risk of social isolation for elders in particular. The core of the initiative is the innovation of the traditional activity of volunteerism providing the 21st century volunteers with a path for personal and social growth through the possibility of creating their own personalized and participative activity. The ComeON! project is aimed at promoting active citizenship of both elderly and young people through a formative intergenerational volunteering experience rooted in the development of social innovation projects aimed at territorial and community improvements. In this context, the objective of the project is to develop, test and validate an innovative intergenerational and peer-to-peer learning approach and environment, integrating youth and elderly volunteerism into a rich active educational experience that integrates leading-edge physical and virtual (“phyrtual”) elements in the effective pursuit of social learning and innovation. The Project will conduct dedicated transnational pilot training courses integrated with concrete community work where seniors, students and teachers will identify and implement micro-projects for social innovation at local level. By participating in this rich educational experience, they will reinforce and develop transversal key competences and tackle simultaneously the challenges of active ageing, 21st century life skills and responsible citizenship. Elders will have visible active roles in their communities and they will either contribute and/or acquire methodologies and tools that will enable them to create, develop and implement projects and initiatives along with the younger generations.
