Applying the CHECk tool to participatory design sessions with children

To encourage ethical practices in participatory design with children the CHECk tool was created. This paper reports on an expert review of the CHECk tool and a validating case study. Four main challenges to the CHECk tool are identified: (1) how to inform children on the research and their role herein, (2) distinguishing between project values and designer or researcher's personal values, (3) accounting for the dynamic nature and social constructedness of values in design, and (4) the emergence of values in all stakeholders including child design partners. We advocate complementing CHECk with interactive storytelling and show how this narrative can be used to not only inform participation and achieve ethical symmetry, but also to negotiate values with child design partners.
