Existing research on the use of technology in participatory theatre in education has paid little attention to the moment-to-moment unfolding that characterises the liveliness at the heart of such practice. In this conceptual article, we show how a sociomaterialist perspective can illuminate the contingent co-emergence of people, things and technologies that produces this liveliness of events. Perspectives drawn from actor-network theory are used to illuminate one example of the integration of technology in participatory theatre in an educational context. The concepts of mutability, disruption, maintenance, potentialities and multiplicities are developed as an explanatory framework for future research and practice in these and similar forms of educational activity.
