“…The relatively recent, though growing, bodies of research on teacher leadership (Spillane et al 2001, Spillane et al 2004, Harris 2003a, 2003b, Lambert 2003, York-Barr and Duke 2004, Murphy 2005, Barth 2007, Yost et al 2009) and distributed leadership (Gronn 2000, Bennett et al 2003, Harris 2005, MacBeath 2005, Spillane 2006, Spillane and Diamond 2007, Gronn 2008, Frost 2008, Leithwood et al 2009) provide additional, compelling incentives for principals to look within their organizations for assistance in enhancing instructional capacity. These bodies of scholarship strongly suggest eschewing the notion of effective school leadership as the heroics of 'charismatic individuals' (Portin et al 2009: 8), and adopting a more inclusive view 'where leadership is distributed and understood in terms of shared activities and multiple interactions' (Harris et al 2007: 345).…”
