Abstract: | This paper explores how people learn about global societal challenges as they work towards them in collaborative activity. It focuses on the activity of volunteering within UK health and social charities and draws upon the approach of Transformative Activist Stance to conceptualize learning in this environment as a form of individual and social transformation. The study is a multiple qualitative case study, which includes three charities that address complex health and social challenges. By exploring how volunteers learn about and address complex societal challenges findings show the transformative opportunities this process offers for volunteers, the charity, and the wider community. |
