There is no doubt that this is the best time in history to learn a language, especially English. We are surrounded by content in English, English language learning apps, English teachers, English courses, information. But one very important question remains: what do we do with all this information? HOW do we study? HOW do we learn a language. One man who knows the answer to this question is Paul Nation. He has been studying and writing about language acquisition and language teaching methodology for more than 50 years, and in this interview he talks about the four strands of language learning, and how by following this simple concept, based on a lifetime of research, both teachers and students can have success at language teaching, and language learning.
