This document discusses authentic materials in language teaching. Authentic materials are any materials not specifically produced for language teaching. They can include TV, films, news, weather forecasts and more. Using authentic materials has advantages like motivation, cultural knowledge, and preparing students for real-world language use, but also disadvantages like requiring more preparation time and potentially difficult language. When selecting materials, teachers should consider how the content can be exploited, its suitability and familiarity for students, and if it supports course goals. Authentic materials offer students a chance to practice real language use and understand meaning without knowing everything.
