“…Involving teachers in such decisions has been shown to result in increased ownership of and subsequently increased commitment to PD's success (Armour & Yelling, 2007;Deglau & O'Sullivan, 2006;Le Fevre & Richardson, 2002;NPEAT, 2008;Parker, Patton, Madden, & Sinclair, 2010;Pissanos & Allison, 1996;Richardson, 1997). Multiple levels of support from facilitators, administration, other teachers, and university partners, have also been found to be a prerequisite for these environments (Deglau & O'Sullivan, 2006;Ha, Lee, Chan, & Sum, 2004;Parker et al, 2010;Prusak, Pennington, Graser, Beighle, & Morgan, 2010). To provide the necessary intensity to achieve future learning and substantive changes, PD also needs to be ongoing and sustained over time with continual follow-up and support for future learning (Parker et al, 2010;Patton & Griffin, 2008ab;Prusak et al, 2010;Ward, Doutis, & Evans, 1999).…”
