“…Despite the growing number of large-scale space education programmes (Roche et al, 2021a), there remains some debate over the theories of learning underpinning astronomy and space education in informal environments (Kovalenko, 2019;Anjos and Carvalho, 2020). Constructivism is one of the most common theories of learning that provides the theoretical foundation for events where public audiences engage with science (Stocklmayer et al, 2010;McCauley et al, 2018), and for young people engaging in space and astronomy in informal learning environments, social constructivism-whereby learning is mediated through social interaction with teachers, educators, and peers-is often the learning theory that underpins the activities (Vygotsky, 1978;Kallery, 2011). The aim of the spaceEU project was to foster a space education community for young people in Europe and it set out to achieve this by implementing a programme of social constructivist activities designed to educate, engage, and encourage young people to better understand the role of European space science, including its benefits to society as well as potential career paths within the field.…”
