“…Reforms implemented at the elementary level typically aim to build school-and teacher-level capacity through professional development initiatives (Coburn, Russell, Kaufman, & Stein, 2012;Leithwood & Louis, 1998;Smylie & Hart, 1999). Building capacity by promoting teachers' individual and collective learning is considered an important prerequisite for a school's ability to change and sustain improvement (Atteberry & Bryk, 2011;Hopkins, 2001;Parise & Spillane, 2010;Sleegers, Bolhuis, & Geijsel, 2005). Coupled with this emphasis on capacity, there has also been increased practical and scholarly attention to teacher professional learning (Doppenberg, den Brok, & Bakx, 2012;Hord, 1997;Mitchell & Sackney, 2000;Stoll, Bolam, McMahon, Wallace, & Thomas, 2006;Toole & Louis, 2002).…”
