“…After a long time in which history didactics paid little attention to teachers (Hasberg, 2010), it is now widely accepted that they are central subjects who have great freedom in the design of their lessons (Münch, 2017b), and therefore that they are responsible for the structuring of history lessons (Schulz-Hageleit, 2014), and have a significant influence on learners' conceptions of history (Evans, 1990). As a result, the beliefs (Bernhard, 2019a;Nitsche, 2019), historical-didactic knowledge, teacher training and practical school experiences of history teachers have been researched in numerous projects in recent years (Maggioni et al, 2004;Popp et al, 2013;Waldis et al, 2014;Fenn, 2015;Schröer, 2015;Thünemann, 2016;Bernhard, 2017;Heuer et al, 2017;Litten, 2017;Ecker, 2018;Lüke et al, 2018;Nitsche, 2017;Resch and Seidenfuß, 2018;Heuer, 2019).…”
