摘要：This paper presents an interview with Merrill Swain, a Canadian researcher who proposed the Output Hypothesis, a way to understand the relevance of producing (by speaking/writing) the foreign language during its learning. According to Output Hypothesis, the learner may notice gaps while, test cognitive hypothesis and think in a metalinguistic way while producing the foreign language. This hypothesis influenced plenty of research in the second language learning/teaching field around the world, considering Brazil as well.
