Authentic vs Non Authentic material

In my personal opinion is designed not for foreign students, but for the real speakers of the language. Refers to authentic texts as texts that are not written for language teaching purposes. Authentic materials is significant because it increases students motivation for learning, makes the learner to face the real language.

-A positive effect on learner motivation.
-It provides authentic cultural information.
-It provides exposure to real language.
-It’s more closely to learners needs.
-It supports a more creative approach to teaching.

Using authentic material, it is inevitable that we face some problems.
Like: authentic materials often contain difficult language, unnecessary vocabulary and complex language structures, which causes lower-level classes. But we can use authentic materials depending of the level of your students.
