The field study described my teaching process in an elementary school in Little Okinawa. I chose praxis-oriented paradigm as my research approach and adopted critical ethnography as my research method. The purpose of this study has two aspects: (1) I would like to understand the learning situations which students had been exposed to and the educational attitudes of the parents. (2) I would like to create a learning environment allowing students’ active thinking and participation in my class by designing teaching projects of Chinese and mathematics. I wish students could gain new concepts about learning from different learning experiences.
