AUTHENTIC MATERIALS
In order to demonstrate and to teach a language in the classroom, there are some real objects or materials that teachers can use. This is what teachers call realia. It is a supporting tool to make language acquisition and production possible. What realia does is to provide learners with concrete vocabulary that permits them to have a direct contact through the senses of seeing, hearing, smelling and touching the objects. As Richards and Rodgers say, real-world materials are brought to class by the students in the form of newspapers, signs, handbills, storybooks, and in the case of adults printed materials from their workplace are also another resource. Students also produce their own materials. Besides, realia does not have to be limited to food or drink. Calendars, coupons, magazines, and fashion may all be recycled to help open life into lessons, and help deal interest.
