In this paper, we outline a Distributed Participatory Design (DPD) research protocol. The protocol is presented through the lens of the World’s Largest DPD Project with children, a hypothetical project in which children address the issue of climate change. The DPD research protocol is based on the protocol template recommended by WHO’s Research Ethics Review Committee (ERC) and on the data from two conference workshops with a total of 45 participants. The contribution of this paper is two-fold: 1) an initial version of a generic DPD research protocol; 2) an exemplification of how to appropriate this protocol for a specific project. We expect this protocol will be iteratively refined and will serve as inspiration for future research practices in Child-Computer Interaction (CCI).
