This study explores whether journal writing and in-class discussion operate for developing reflective teachers and investigates main issues understood and enhanced by Korean EFL teachers through journal writing and in-class discussion. Seven participants in this study were all in-service English teachers as well as graduate students taking a course on ‘reflective teaching’ in a large university in Seoul. They were supposed to write journals on the web once a week and to read others’ journals for the following in-class discussion. Main issues enhanced by participants through journal writing and in-class discussion were as follows: Teachers’ beliefs about profession as English teachers in Korea; Teaching techniques to make students’ learning successful; Teachers’ perceived difficulties in current teaching. As to the feasibility of journal writing, most of the participants reported that journal writing had been a turning point to be a reflective teacher and in-class discussion made them find lots of useful teaching tips and solutions for the problems they had met. This study provides teacher trainers and teachers themselves useful insights to develop reflective teaching and to better understand the current issues of English teaching in Korea.
