“…Previous literature has also shown that pupils' enjoyment, anger and anxiety are related to teachers' instructional behavior (Becker et al, 2014, Gläser-Zikuda & Fuβ, 2008Sarason, 1984). For example, lack of feedback from teachers, unstructured learning material, unclear instructions and excessive external teacher control have been shown to cause negative emotions such as anxiety and anger (Anttila, Pyhältö, Soini, & Pietarinen, 2016;Becker et al, 2014;Rantala & Määttä, 2012;Sarason, 1984). Moreover, there is some tentative evidence that teachers who experience high job satisfaction are less stressed and exhausted and are perceived by pupils as giving better-quality instruction (Klussmann, Kunter, Trautwein, Lüdtke, & Baumert, 2008;Kunter, Klusmann, Baumert, Richter, Voss, & Hachfeld, 2013).…”
