Why should we have proper and clear idea about understanding Communicative Language Teaching? It is simply because our national English curriculum, thousands of students, and guardians are directly influenced by CLT. It was introduced in our national curriculum in 1997. Since then the term has come to mean different things to different people. And this is not the fact in Bangladesh alone, in many non-native countries misconception has developed in different grades. A number of reasons for the confusion and misconception can be attributed to it. CLT has developed extremely rapidly over the past fifteen or so years around the world and has now moved a considerable distance from its original practices though without substantially changing its original principles. This is the most persistent and most damaging misconception.
