In this study, the PBL class was applied to a Vietnamese video class. 13 learners were divided into 3 groups, and it was examined whether all learners grew toward their learning goals, and if so, through what process they grew. When group 1 announces a task, groups 2 and 3 perform peer evaluation and submit a peer evaluation sheet. For this, group 1 categorized the contents of peer evaluation into reflecting, partially reflecting, revised, and not reflecting to prepare the presentation evaluation sheet. Further, they were required to write a reason why “not reflecting.” A reflection log was also submitted. As a result of the above, the assignments were immediately revised, supplemented, and developed every week through peer and instructor evaluation. Through this process, the instructor learned in detail what kind of reflection the presenter and team members were doing each week. In particular, learners achieved ‘up-leveling’ with the activeness of immediately accepting each other’s strengths while conducting peer evaluations on each other’s presentations. This shows that the weekly assignments are improved, while the competencies of both the presentation team and peers are developed at the same time.

The purpose of the study was to explore the reflective process of pre-service English teachers by analyzing critical incidents entered in their teaching journals during a fourweek student teaching practicum. Thirty-three student teachers were asked to report critical incidents in their journals once a week, especially focusing on „lesson breakdowns‟ or „events that deserve critical significance‟ during a lesson. 133 journal entries were collected and a total of 104 critical incidents were analyzed to see some aspect of secondary classroom teaching and the reflective processes that student teachers went through right after the incidents. From the content analysis, it was found that many critical incidents happened during the initial stage of lesson and were mostly caused by student teachers‟ lack of experiences in either time management or material preparation tailored to students‟ level. By describing and analyzing critical incidents, student teachers became more aware of their assumptions about language teaching and learning and tried to transfer knowledge into real practices. A survey administered after the practicum also revealed that self-observation of critical incidents in their own classroom helped them to generate powerful insights about teaching and to develop reflective teachers.

The purpose of this study is to take a close look at team teaching between a Korean elementary English teacher and a native teacher of English and thus to explore ways that team teaching can be performed more effectively. The data consists of teaching journals and an interview. Teaching journals were written by the Korean teacher and the native teacher for one semester while co-teaching. The analysis of data revealed the followings. First, the role relationships between the two teachers changed dynamically as the native teacher had more experiences of teaching. The native teacher was a novice at first, but she became the associate and sometimes team leader in the end of the semester. Second, the Korean teacher's efforts to communicate with the native teacher regarding the contents and methods of teaching helped the native teacher progress in teaching skills and management of class. Third, the Korean teacher felt stress due to too much work and responsibility related to team teaching although she found the experience of team teaching rewarding in terms of her professional development. Finally, it was found that activities and games rather than reading and writing were more appropriate for team teaching. Based on these findings several suggestions were made.
