“…While it is true that this topic has been widely addressed in primary school classrooms, it should be noted that most of the work published to date has focused almost exclusively on the ideas of students (Andersson et al, 2019;Carvalho et al, 2004;Dempster & Stears, 2014;García-Barros et al, 2011;Óskarsdóttir et al, 2011;Prokop et al 2009;Reiss & Tunnicliffe, 2001;Reiss et al, 2002;Rowlands, 2004;Teixeira, 2000).
