“…The theoretical starting points for our study are play theory (Huizinga, 1955; Nachmanovitch, 1990), game studies (Juul, 2004; Salen & Zimmerman, 2004, Mäyrä, 2008), and the Technological Pedagogical Content Knowledge (TPACK) model of teacher's knowledge (Mishra & Koehler, 2006; see also, Shulman, 1986; Dorfman, 2013; Bauer, 2014). Huizinga's (1955) play theory is often used as a point of departure for discussing the pedagogical significance of entertainment games (Juul, 2004; Salen & Zimmerman, 2004; Miller, 2012), despite having been criticised in gaming literature (Woodford, 2008; Consalvo, 2009; Calleja, 2012).…”
