“…PLD design that helps teachers integrate GIS into the classroom is well documented (e.g., Bednarz, 2004; MaKinster et al, 2014). The focus of effective programs is on teaching with GIS as opposed to teaching technology skills in isolation (e.g., MaKinster et al, 2014; Moore et al, 2016; Trautmann & MaKinster, 2010); however, building GIS skills through application is important to increase teachers' confidence to implement in classrooms (e.g., Almquist et al, 2014; Harte, 2017; Moore et al, 2016; Price et al, 2014). Identifying the utility of this PLD is critical for both participants and school administration, as teachers are more likely to learn GIS skills when they perceive its' usage will improve their teaching (Trautmann & MaKinster, 2010) and the more support teachers receive from the school, the more likely they are to attend PLD (Lay et al, 2013).…”
