Participation is an increasing focus among science centres and museums. If once it was mainly connected to visitors’ points of view and opinions on ‘hot topics’ and their dialogue with scientists and experts, today’s participation is more varied, thanks in part to changes “powered” by social media. Participation is now included in activities, such as content design, which was once only performed by a small team of professionals. In this session we will learn more interactive and responsive ways to involve different actors in the design of exhibitions and events, etc.
