“…The characteristics of schools with teacher leadership culture are as follows, respectively: (i) professional cooperation emphasizes the development and improvement of the school (Borchers, 2009), structuring schools as a learning community (Chamberland, 2009;Danielson, 2006;Gaffney and Faragher, 2010;Harris and Muijs, 2005;Hunzicker, 2012) and carrying out collaborative studies in line with the common objectives (Chamberland, 2009;Gaffney and Faragher, 2010;McCay, Flora, Hamilton and Riley, 2001;Muijs and Harris, 2006;) (ii) school administrator's support emphasizes the distribution of leadership across the school (Brosky, 2009;Chamberland, 2009;), sharing in school management and processes (Beachum and Dentith, 2004), an encouraging understanding (Heller and Firestone, 1995) and effective feedback behaviors for the teacher (Buckner and McDowelle, 2000). Ensuring school administrator's support is associated with the fact that teachers exhibit more leadership behaviors at school and make use of professional development opportunities.…”
