FIRST STEP TO DEVELOP COMPETENCE IN ENGLISH

One day, one of my students tries to utter words in English. You know what it is? The universal world that is love. He says "I love you". You know where he learn the words? He learns from other people, from TV, read on the door of WC. he learns from friend, but not from teacher. Teacher never teaches that sentence to teacher.
If you want to have a research whether teachers teach their students such expression, I guarantee that you will get nothing from teacher. So, dealing with teaching and learning English, the easiest and effective way is learning by environment.
