The document discusses the use of authentic materials in foreign language classrooms. It defines authentic materials as materials produced for real-life purposes rather than language teaching. Authentic materials provide exposure to real language use but can be difficult for lower-level students. The document examines sources of authentic materials, criteria for selecting them, and how they can be used, including simplifying texts and designing partial comprehension tasks. It also discusses arguments for and against their use, and interviews language teachers in Saudi Arabia who express support for authentic materials if implemented gradually based on student level.
