Purpose: This study considers the pedagogical dimensions of an event concept ]that combined participatory theatre and social scientific research to approach questions relating to ethnic relations and racism. The article aims to establish, with the help of a practical case example, the notion of public social pedagogy. Approach: Ethnographic research on 24 participatory theatrical events. The analysis utilizes the taxonomy of public pedagogy by Gert Biesta to provide an empirically informed theoretical 'autopsy' of the events. Findings: The analysis shows the pedagogical and societal importance of fostering encounters, encouraging communal discussion and nurturing dialogic competencies. "Public social pedagogy" would specifically address pedagogical processes relating to the public sphere, which revives the tradition of public deliberation. Practical implications: The study directs attention to pedagogical processes within the public sphere which have not been very prominent in social pedagogy or citizenship education. The autopsy of the participatory theatrical events provides perspectives for similar artistic interventions.
