The purpose of this study is to suggest ESA, a teaching procedure for effective communication in the classroom. Until now, PPP(present-practice-produce) is thought to be one of the most popular teaching model in this field. However, this traditional teaching model puts the interaction at the last part of the class so that real communication is apt to be neglected. ESA(Jeremy Harmer, 1998) is a nice alternative to PPP and it has three stages: Engage, Study, Activate. (1) Engage : In this phase, teacher tries to arouse the student's interest and engage their emotion. (2) Study : The ‘Study' phase activities are those which focus on language and how it is constructed (3) Activate : In this phase, the exercises and activities which are designed to get students to use the language as communicatively as they can. The most remarkable advantage is that ESA has flexible phase and teachers can use different types of teaching model such as ESA, EAS, EASASEA. Moreover, this new teaching model might be helpful to be student-centered class with various activities. (Hankuk University of Foreign Studies)
