Basically language is a tool with which you can use when you learn something or so.Especially in Korea, English itself can’t be helpful for students because English is only used in classroom. For the learners or their parents, learning English is a kind of investment, not just something fun. So the purpose of learning English in Korea is obvious. It is for entering a good school, or getting a good job. So to achieve this goal, I prefer CBI;Content based instruction. This is student-centered and easier to get students motivated and interested by generating stimulating content instruction and materials. During the lesson, learners will get to know how to learn something in English and to be able to use it for further learning at higher institutions. It probably will be a challenge to the teachers to give a lesson about certain subjects in English. But if it’s not too professional or specialized, teachers can keep up the lesson and as time goes by, the professionalism of the teachers will improve. Then the teachers and the academy will be growing much more. Target ages and levels can be various.
