The objectives of this study were to propose integrated teaching by applying the 'Hanaro Teaching Model' to the expression activity class in elementary school and to observe and analyze how teachers’ perception of teaching contents and methods are changed in the teaching process. Results derived from this study are as follows. First, the participants planned the contents of expression activity class that can develop both skills and insight as a composite art comprehending body cultural heritages. In the process, they aimed at dancing diverse dances through various indirect experiential activities as the objective and, at the same time, the contents of their teaching plan, and intended to help students internalize the value of expression and pursue it in their life. At the same time, this can be understood as a possibility of reflecting various needs and interests of both teachers and students. Next, for the methods of expression activity class, first, the participants perceived that, for students’ meaningful education activities, it is more effective to integrate methods and curriculums in operation rather than to approach individual skills. Second, by practicing compassion, justice, propriety and wisdom and tidying up the body and the mind, teachers created cordial class atmosphere that the teacher and students respect each other. This had a positive effect on teachers' satisfaction with their teaching and vocational achievements. Third, as they designed various indirect experiential activities as much as their abilities allowed, the research participants overcame the burden and fear out of their lack of abilities in practical teaching and restored their confidence. What is more, they developed abilities to operate their class efficiently together with students and to utilize given school conditions and environment to the full. Fourth, as the teachers perceived the expression activity class as a learner-oriented class that the teacher and students cultivate together as a learning community, the teachers experienced successful teaching as education experts through reflection on their class and, as a result, they became able to give more meaning expression activity classes.
