The present study aimed to investigate the satisfaction of pre-service teachers with the completely online course instructed with the flipped classroom model. The study was conducted with the explanatory sequential mixed design. The participants included 117 pre-service teachers. Data were collected during the 2020-2021 academic year fall semester with the Online Course Satisfaction Scale and face-to-face interviews. The study findings demonstrated that the pre-service teachers were satisfied with the online course. The satisfaction level of female participants was higher, and the differences were not significant based on the student department. On the other hand, the participants stated that there were systemic and instructor-oriented problems. Furthermore, it was determined that ease of use was an important factor in predicting satisfaction. Ease of use varied based on PC ownership, but not based on tablet ownership. Satisfaction did not differ based on both PC and tablet ownership. It was found that the flipped classroom model exhibited interactional challenges. However, the model had advantages due to its structure that allowed flexibility. It could be suggested that the findings of the present study would contribute to future studies that would address flipped classroom method and satisfaction with online courses.
