“…Findings from various studies regarding formal learning opportunities (e.g. Beck, 1993;Brückner et al, 2015;Jüttler and Schumann, 2019;Kaiser et al, 2019;Lüdecke-Plümer and Sczesny, 1998;Macha, 2015;Müller et al, 2007;Nagy et al, 2012;Schumann et al, 2011;Siegfried, 2019;Sticca et al, 2018;Walstad and Rebeck, 2001) can only be compared to a limited extent not only because of their heterogeneity at the curricular level, but also because of their different approaches to definitions and measurements. Nevertheless, we can summarise that learners who were able to perceive more formal learning opportunities with economic content (higher grade level, advanced course, type of school) show a higher degree of economic knowledge (Ackermann and Siegfried, 2019;Beck, 1993;Hoidn and Kaminski, 2006;Lüdecke-Plümer and Sczesny, 1998;Müller et al, 2007;Schumann and Eberle, 2014;Walstad and Rebeck, 2001).…”
