The purpose of this study is to investigate what and how Korean student teachers reflect on their practical experiences in the context of classroom environments in order to find concrete and effective ways for teacher educators to promote their student teachers\' practical reflection. What underlies this study is the idea of teacher education based on the concept of Schon\'s
\"reflective practitioner,\" according to which the practical competency required for would-be teachers can be best fostered through their reflection on their own teaching experiences during the practicum.
For this study, twenty eight student-teachers were asked to write journals about their experiences while they were placed in secondary schools for 4week-practicum. And their journals were assessed in terms of the levels of reflection as well as of the contents of reflection. The levels of reflection were assessed by the six-level model, which was modified from the Hatton and Smith\'s model. The contents of journals were also analyzed by a framework, which was modified from Bain\'s model.
The results of this study are as follows. As for the levels of reflection, about 80% of the student teachers reached up to only the lower three levels and among them about 40% remained the lowest level. The remaining 20% were spread from the 4th level to the 6th level. As for the contents of reflection, the subject that students were most concerned with in their reflection was \"themselves\"(43.9%) and then \"teaching\"(29.3%); all other topics were relatively
the low concerns of the student teachers.
As a conclusion, we can see, the students who were interested in \"teaching\" tended to reach the higher level of reflection, while those who were concerned with \"themselves\" tended to remain the lower level of reflection. This implies that teacher educators should develop different teaching strategies to promote student teachers\' practical reflection in accordance to the student teachers\' levels and concerns of reflection.
