“…Even authors that focused on other denominations often seemed to use the term "team" somewhere in their article: some studies started off by writing about "collaboration", "community", "department" or "critical friends group" and then later on referred to "teams" (mostly as a form of collaboration) without giving further explanation (e.g. Achinstein, 2002;Avila De Lima, 2001;Curry, 2008;Datnow, 2011;Dickinson, 2009;Kelchtermans, 2006;Leonard & Leonard, 2003;Lomos, Hofman, & Bosker, 2011;Scribner, Hager, & Warne, 2002;Visscher & Witziers, 2004;Williams, 2010). This mix up of different terms is confirmed by Westheimer (2008) who mentioned that schools use different denominations to describe collaboration between teachers, one of them being "teams".…”
