The issue of multicultural education had become a focus in the process of education reform and connected with classroom teaching intimately. However, there wasn't a subject named "multicultural education" in elementary school. In order to understand how multicultural education was accomplished through teaching process in elementary school, participant observation and interview were used in this study. Two homeroom teachers, one English teacher and one teacher of arts and humanities were interviewed. Banks's five dimensions of multicultural education were used to design guidelines for a semi-structured interview and as a basis for data analysis. It was found that the teachers' experience and beliefs affected their teaching behavior. The results of this study revealed that learning experience of multicultural education would help teachers to take the spirit of multicultural education into practice. According to teachers' believes of multicultural education, they could accommodate their teaching to the students of different character. And teachers also tried to combine multicultural issue with curriculum. Furthermore, teachers carried out multicultural education in hidden curriculum, teaching process, teaching strategies and evaluation in their teaching practice.
