“…The findings contribute to previous research on the differentiated impact of transformational leadership practices on teachers' engagement in professional learning activities as mediated by perceptions of the work environment such as positive interdependence (Dionne, Yammarino, Atwater, & Sprangler, 2004;Jung & Sosik, 2002;Korek, Felfe & Zaepernick-Rothe, 2010;Staples & Webster, 2008;Tjosvold, 1986). The findings from this cross-sectional study also suggested a pivotal role of self-efficacy beliefs (Salanova, Bakker & Llorens, 2006;Schyns, 2004). The results therefore point towards the beneficial role of the interplay between organizational and psychological conditions in enhancing engagement in learning activities in the context of change (Korthagen & Vasalos, 2005;Kwakman, 2003;Leithwood, Jantzi, & Mascall, 2002;Stoll, Bolam, McMahon, Wallace & Thomas, 2006;van Woerkom, 2004).…”
