“…Although scholarship on different embodiments of MKT is vast, there also exists research on the understanding of SKT. SKT became a subject of research projects with in-service teachers outside of the United States (Burgess 2007(Burgess , 2009a; Estrella, Olfos, & Mena-Lorca, 2015;Watson, 2001;Watson, Callingham, & Donne, 2008;Watson & Nathan, 2010) as well as research done with preservice teachers (PSTs) in the United States (Groth, 2014).
