Museums and science centres increasingly involve themselves in psychological and educational research. The type of research initiated greatly varies within and among centres. Research ranges from theory-motivated academic studies on the one side to prototyping on the other, each with their own aims, benefits and drawbacks. In this session four science centres will present the range of psychological and educational research that they have been initiating. They will present choices they make about the types of research, the designs and setups, the things they learned from research, and how they share new insights within the organisation. Most of all, they will share their own curiosity-driven learning process.
