This workshop explores learning in Participatory Design (PD). We invite the PD community to reflect on the multiple ways learning can strengthen and expand how we frame and drive participatory design to reflect on how we can expand learning in PD to gain an understanding for the complex system we are all part of, for the interdependence of social, ecological and economic systems. Through this workshop, we will invite participants to address questions such as: What theories and concepts can be used to understand learning in PD? What kind of approaches are used to foster learning in PD? How is learning evaluated in PD? The workshop will bring together members of the PD community interested in these questions, and serve as the basis for developing ongoing and new collaborations around the topic of learning in PD.
