“…The role of teachers is defined as the set of expectations and expected behavior of the teacher in the various social groups he meets (Androutsou, Kortesi-Dafermou, & Tsafos, 2016;Avgitidou, & Gourgiotou, 2016;Konstantinou, 2015;Ntouskas, 2007). Specific expectations influence teachers' actions and perceptions of their role (Anastasiou, 2017;Adams, 1970;Broeder & Stokmans, 2012;Burke, 1997;Heckscher & Applegate, 1994;Levinson, 1986;Linton, 1936;Makovec, 2018;Mavrogiorgos, 1998;Papaikonomou, 2014;Tsardakis, 1995). Teachers are required to perform many different roles because they interact with different social groups and these groups have different expectations of him (Bates & Harvey 1975: 106;Frydaki, 2015;Holland, Lachicotte, Skinner, & Cain, 1998;Heckscher et al, 1994;Konstantinou, 2015: 121;Lunenberg, Dengerink, & Korthagen, 2014;Xochellis, 2006: 47-48).…”
