This study adopts the Problem Based Learning (PBL) for pre-service teachers in teacher education program. The reasons to adopt PBL are the class scale is not a small class, the contents are too many to teach, and the technologies are ready to be used in classroom. This study used an intermediary, movie, for scenario to student to define the problems and to search for information in order to report their findings. Since this is not a required course, more than ten people took this course. Therefore, adopting PBL, the groups using, in the normal scale class in higher education is another modification. The purposes of this study are to evaluate this adopting PBL processing and to find the chance to improve the PBL course design. The methodology of this study is the text mining with KeyGraph technology. Thirty seven pre-service teachers’ feedbacks are analyzed. The feedbacks were from those students who finished three cycles of the PBL processing. Two of the cycles of the PBL processing are the students learning educational special topics by themselves. The last cycle of PBL processing is to train the pre-service teachers how to run the PBL course in the future. The results indicate that the important factor is “discussion” and rare and important factor is “movie” (intermediary) for adopting PBL course.
