“…In environments where teacher leadership is encouraged, practices towards ensuring collaboration among colleagues, school administrators' support, and a supportive work setting are significant (Demir, 2014). On the other hand, the elements that improve teacher leadership include principal support (Hart, 1994;York-Barr & Duke, 2004;Wenner & Campbell, 2016), teacher autonomy (Wenner & Campbell, 2016), providing teachers with time and resources (Chew & Andrews, 2010;York-Barr & Duke, 2004), common vision (Chamberland, 2009;Gaffney & Faragher, 2010;Muijs & Harris, 2006), sharing leadership (Brosky, 2011;Chamberland, 2009), school structure and processes (Beachum & Dentith, 2004), team leadership (Gaffney & Faragher, 2010), school-society relationships (Beachum & Dentith, 2004), learning communities (Chamberland, 2009;Gaffney & Faragher, 2010;Hunzicker, 2012), participation in decision-making and developing a common curriculum (Chew & Andrews, 2010), paying attention to trust, respect, and ethics at school (Beachum & Dentith, 2004;Gordin, 2010;York-Barr & Duke, 2004), well-defined tasks (Muijs & Harris, 2006), and a culture of constant development at school (Borchers, 2009). …”
