The study investigated the experiences and perceptions of pre-service special education teachers who had adopted flipped classrooms. The participants in this study were fourteen second- and third- year students majoring in special education at K University. They took a course entitled “Theory of Early Childhood Special Education,” which adopted the flipped learning format for one semester. The researcher conducted individual interviews to identify participants’ experiences and perceptions with respect to the flipped classroom. The results of the interviews were transcribed, and the transcriptions were analyzed by constant comparative methods. Three themes and six subcategories were derived: (a) opinion about operation of flipped learning, (b) experience with flipped learning, and (c) proposals to improve flipped learning in universities. Based on the results of this study, various teaching support methods in teacher training institutions were discussed to improve the training of special education teachers.
