“…Teachers need to have subject and pedagogical knowledge to be able to teach about ESD (Summers, Corney, & Childs, 2003). Scholars agree that the preferred teaching approaches to ESD should be student-centered (McNaughton 2012;Tomas, Girgenti, & Jackson, 2017;UNESCO, 1992) experiential, participatory (Lysgaard & Simovska, 2016), praxis-orientated, place-based, interdisciplinary (UNESCO, 1992;Saka & Sahintűrk, 2013), inquiry-based and transformational (Biasutti, 2015;Biasutti & Frate, 2017;Christie et al, 2013;Corney & Reid, 2007;Cotton et al, 2009;Tomas, Girgenti, & Jackson, 2017;Wals & Jickling, 2002). These teaching/learning methods promote changes in behaviors and ways of thinking and relate not only to knowledge but also to processes, because these methods teach learners how to think (Biasutti, 2015).…”
