Teaching English communicatively requires creativity and good authentic materials.
Your educational background and interests play an important role in becoming a better ESL teacher, but you don’t necessarily need to be a science major to teach difficult science topics. Browsing the science section of the local newspaper will lead you to interesting and fun articles that you can use in the ESL classroom.
Communicative TESOL goes beyond teaching ESL. The Communicative Approach is the most effective method for teaching a language because students study the language in real context and it helps them expand their knowledge of the world using the English language. Communicative TESOL is both fun and effective.
Social media sites such as You Tube and Facebook are excellent for finding great authentic materials. You Tube provides millions of free documentaries, songs, and movies, and Facebook pages feed updated material to your account.
