This paper investigates aspects of informal and non-formal learning that emerge through adults’ participation in collective actions and social movements. Drawing on qualitative data derived from interviews with members of social collectives in an urban area of Athens (Greece), the study illustrates how these spaces function as dynamic learning environments. Participants develop practical knowledge, social skills, critical awareness, and a deeper understanding of social issues. Moreover, engagement in collective actions also fosters emotional bonds, solidarity, and processes of personal transformation. The findings underline that learning is not confined to formal settings but emerges meaningfully through participation in civic life. The study highlights the pivotal role of collective action in promoting adult learning and self-awareness, contributing to the broader dialogue in the field of adult education by demonstrating how involvement in social groups constitutes a significant site for both individual and collective transformation.
