The question is a fair one. The concept of teacher resistance is now common lore among sociolinguists, who have heard about or who have experienced the rejection of well-intended efforts to bring linguistic knowledge to classrooms and schools. When we explain that we have had hardly any ‘resistant’ teachers—only two we can recall, over the course of working with thousands of teachers for the past decade—we are generally met with incredulity, quickly followed by a request to learn how we've made it work.
