Field Evaluation of the Design of a Family-Participatory Exhibition Experience for Circular Economy Awareness and Pro-Environmental Action

Abstract

This study explored the potential of exhibition experiences involving family participation to address the limitations of information-oriented environmental education for children and foster understanding of the circular economy and willingness to engage in environmental action. A maze-based exhibition was designed through literature and case analyses, prototype testing, and an expert focus group interview (FGI), and was then installed and operated at the ‘2026 DDP Children’s Design Festival: DDP Land’. Immediate user responses and on-site behaviors were evaluated using 101 questionnaires, each comprising child- and guardian-response sections, along with video-ethnographic observations of 20 participant groups. Guardians’ perceptions of children’s understanding of environmental issues, pro-environmental self-efficacy, and willingness to act were generally positive. Elements combining play and physical activity emerged as key memorable components, while repeated participation was observed on site. Guardians’ explanations and encouragement to take action, along with joint participation by children and guardians, indicated the exhibition’s potential to foster family dialogue and willingness to engage in environmental action. However, the findings should be interpreted in terms of perceived understanding, willingness to act, and immediate on-site responses rather than actual behavioral change. This study is significant in translating the circular economy and environmental action into a participatory exhibition experience for children and their families that integrates physical activity, play-based missions, family dialogue, action pledges, and rewards.
