“…The most recent studies of school practices emphasize that in-service workshops and training courses and degree upgrading programmes represent a narrow vision and ineffective forms of TPD (Borko, 2004;Denton & Hasbrouck, 2009) because those forms are inadequate to address the complexity of educational problems and issues in classroom contexts (He & Ho, 2017). Instead, researchers have argued that significant TPD should be carried out in the context of job-embedded, collaborative, and school-based activities (He & Ho, 2017;Kwakman, 2003;Little, 2012;Opfer & Pedder, 2011;Timperley, 2011;Tran et al, 2018;Webster-Wright, 2009). This social aspect of TPD (Rosenholtz, 1989) raises the importance of reshaping typical norms in the school from privacy, individualism, and tradition to collegiality, collaboration, empowerment and experimentation (Barth, 1990;Clement & Vandenberghe, 2001;Denton & Hasbrouck, 2009;Gumus, Bulut, & Bellibas, 2013;Heck & Hallinger, 2014;Leithwood & Louis, 2011;Saphier, King, & D'Auria, 2006;Thoonen et al, 2012).…”
