The purpose of this study is intended to explore an effective way of teaching English grammar, which is geared toward improving students' communicative competence in the English language moreover, they ought to be schooled in the grammar so that they may develop their grammatical knowledge and abilities to commonly apply it, both of which are going along with each other as their foundation of communicative competence.
Thus, this study is proposed for the grammar instructions placing the focus upon the improvement in communicative competence. First, it is logically effective to explain the form, meaning and pragmatics of the English grammatical rules to such learners in an EFL environment. Second, the learners ought to be given the instructions concerned with grammatical patterns dealing altogether with the language constructions, structures, and meaning which can enable them to produce correct sentences or expressions by themselves. Third, the learners have to understand grammatical structures and the meaning expressed by the structures on the basis of word orders.
Therefore, the reasonably suggested steps, so far, of grammar instructions are as follows. In the first step of grammatical instructions, such students in an EFL environment must learn and understand the illustrations of grammatical structures which show both grammatical rules and communicative functions. In the second step, they are further brought to repeated practices of grammatical constructions enough to unconsciously make practical application of them. And lastly, their communicative practices, such as descriptions and role plays, are sure to include proper grammar instructions of integrating grammar practices and communicative language usages, especially with regards to their particular meanings. because grammatical competence is extremely important to communicative competence. Seemingly it is essential to enhance grammatical competence in terms of acquiring communicative competence as well. Because grammatical knowledge can never be unconsciously acquired by the students in an EFL environment, such as in Korea. Therefore, the learners have to take English grammar courses
