The purpose of this study is to develop a teaching-learning model that uses ‘questions’ as a method for effective interaction between teachers and students in problem-based classes targeting Korean language students for academic purposes and to clarify its significance. This study has utilized ‘expert review’ to increase internal validity and ‘on-site evaluation’ to increase external validity among the model validation strategies suggested by Richey & Klein (2007). It has also developed a KAP teacher question facilitation model for the effective interaction between teachers and learners by dividing it into ‘before assignment-during assignment-after assignment’ stages. This model can be used as a question guide when developing textbooks and assignments and is believed to be able to be applied in various teaching-learning processes.
