The document discusses the use of realia, or real objects, in English language teaching. Realia are defined as everyday objects used to bring the classroom to life and relate language to things in the real world. The key advantages of using realia include making the learning experience more memorable for students and creating a connection between objects and language. However, authentic materials may be too complex and demotivating for students depending on their level. The document provides examples of suggested activities using realia and considerations for implementation such as purpose, preparation, and time frame.
