Koreans have been studying English since kindergarten, but students have difficulty hearing, speaking and writing in English. Traditionally English learning was not conversationally based. And most Korean teachers were not good at speaking English. This resulted in people who knew grammar and vocabulary, but were shy and scared to make mistakes speaking English. More recent English textbooks focus on speaking and listening rather than reading and writing. The parents want their children to be sent to institutes with native speakers so they will have good pronunciation and do well speaking English. However, due to the university entrance system, grammar and reading became important for middle and high school students.

The stature of English teachers
Korea is a very conservative country and status is important in most relationships. If you are older your status is higher. If you are married you status is higher than that of someone who is single. Of course parents have a higher status than children and in like manner teachers have a higher status than students. In fact being a teacher is one of the higher status jobs in this society although it has been lowered to a lot more than before
