In the field of research and development related to science and technology centres (STCs) and museums, there has, for a long time, been a pronounced interest in increasing the understanding of what experiences visitors gain, how they consider exhibitions and what they have learnt during visits. Research studies within the field have therefore often focused on visitors’ learning outcomes and the number of studies adopting pre- and post-methodologies is quite extensive1.This approach and research focus can also be understood from a desire to create and enhance the institutions’ legitimacy and their capacity to finance further activities.
