This study is based on a qualitative perspective to discuss the student teachers' classroom discourses. I explored three aspects of student teachers' classroom discourses (a) The communication of prepositional information, (b)The establishment and maintenance of social relationships, (c) The expression of the speaker's identity and attitudes. I observed 25 student teachers' teaching episodes in the naturalistic settings. B'y collecting their reflective journals, reports and in-depth interview, I explai ed how they make sense of their teaching process. The findings provide a realistic picture about the orocess of practical training and suggestions for future student teachers.
