As a result of the project "Krona eller klave? Different sides of coins and credits during Gothenburg's 19th century", an exhibition is being produced by the Gothenburg City Museum. It will be based on the results of the project's research team, the museum's in-depth documentation of the collection and dialogues with the target group. In addition, the perspective will be broadened to discuss how economic and other values arise, how they change over time and how they have, and have had, an impact on us all in a global world. The exhibition will discuss the content of different types of values, such as economic, cultural, historical, symbolic and national. But also how these values are expressed in museum practice and how they can be changed through the exhibition medium and the visitor's experience. The aim is to engage students in mathematical thinking and contribute to a positive development of mathematical knowledge in Swedish schools, while providing skills development in museum pedagogy and exhibition production.
