As language teachers, simplifying grammar or culture is tempting. However, learning a second language is not easy nor simple. It takes not only effort but empathy and tolerance of ambiguity. In 1993, Claire Krasmch proposed a conflict approach. The philosophy of conflict does not imply to avoid scaffolding but, precisely, to prepare students for the linguistic and (inter)cultural blurriness of any L2.
So next time you teach, ask yourself. Is this scaffolding or saving face time?
