“…Not only is professional learning conceptualized as critical for increasing educational quality and enhancing children's learning and developmental outcomes (e.g., Lazarri, Picchio, & Musatti, 2013;Munton et al, 2002;Peleman et al, 2017;Penn, 2009;Vandenbroeck, Peeters, Urban, & Lazarri, 2016), but specific elements of professional learning (in both initial and continuing education, or preservice and in-service learning) have been identified as essential to transforming early childhood educators' and preschool teachers' professional identities and practice. For example, critical and supported reflection (Thomas & Packer, 2013), learning experiences that target entire teams (Vangrieken, Dochy, & Raes, 2016), collaborative and empowering practice (Helterbran & Fennimore, 2004), long-term interventions (Peleman et al, 2017), and competent leadership (Colmer, Waniganayake, & Field, 2008) have all been found to be effective means of supporting professional learning.…”
