Another similar opinion comes that authentic materials are not for language teaching purposes, but designed texts used for real life use for interactional and transactional purposes.

• At first, authentic materials were used for native speaker only, but since 1970s some teachers used it for teaching purposes. The development of ELT finally places the authentic materials not only for native but also for EFL as their learning media. Authentic materials as printed materials, which are used in classroom in the same way they would be used in real life.
