“…Teacher collaboration has generally been desired, more than experienced, by teachers, as there is limited evidence reflecting authentic teacher collaborative work (ROLDÃO, 2007;TARDIF;LESSARD, 2005;VANGRIEKEN et al, 2015). Several studies (ABELHA, 2011;ABELHA;MACHADO, 2018;COSTA-LOBO;ABELHA;CARVALHO, 2017;FORTE;FLORES, 2014;MCLAUGHLIN;TALBERT, 2001;SAWYER;RIMM-KAUFMAN, 2007) have demonstrated that teachers' work is usually conducted isolated and behind closed doors, which means it is essentially individual (TARDIF; LESSARD, 2005). Regarding this matter, Thurler (1994) warns that this solitary work, which may appear to "protect" teachers from each other, also prevents them from seeing, reflecting on, and understanding what colleagues are doing inside their classrooms with their students.…”
