The purpose of this study is to identify and address the problems to be considered in the process of interpreting achievement standards and designing the Korean Language and Life Korean Language textbooks for the 7th grade in line with the Korean language curriculum revised in 2007. A case on how to organize a section will also be presented. In order to conform to the objectives of the revised curriculum, the editor has to construct content such that learners understand the elements involved in the production and reception of texts and enhance their ability to practically produce and receive various texts. The writer therefore explores how to reflect the achievement standards for textbooks such as Korean Language and Life Korean Language in the `internet bulletin board debate` on the speaking strand in the 7th grade, and presents the direction to be taken when designing and organizing a section. This paper is from the writer`s perspective that the internet bulletin board debate should be operationally defined and formalized as an educational genre since it is a relatively new and flexible text type. The main idea is that the Korean Language textbook should be divided into two parts: `principles` and `reality`. The latter should be particularly useful in helping learners understand the characteristics of the text and participate in text production. In addition, the writer proposes that the Life Korean Language textbook should include selective or integrated content that encourages the learners to participate in activities such as discussions or argumentative essay-writing. Finally, he points out certain constraints that need to be addressed in the process of designing a textbook in line with the text-based curriculum, and suggests some ways in which this can be accomplished.
