 Authentic and non-authentic materials The term materials can apply to virtually anything that a teacher uses to help the teaching process in the classroom. Common teaching materials include items such as worksheets, newspapers, pictures, textbooks, and video recordings. These teaching materials are often classes either authentic or non-authentic depending on their origin and how they are used. Authentic material refers to items that have not been designed or adapted for use in an English language classroom such as magazines, newspapers, video clips, and song lyrics. In contrast, non-authentic material refers to anything that has been designed specifically to aid the teaching process such as worksheets, textbooks, and instructional CDs or DVDs.
