Developing the digital competencies and innovativeness of preservice teachers enables them to utilize technology more effectively and efficiently in their future professional life. However, poor technology training can lead preservice teachers to potentially misuse technology in the classroom. Moreover, little is known about how to design effective technology training courses in order to develop the digital competencies and innovativeness of preservice teachers. Therefore, this study examined a course designed with the flipped learning approach and its impact on preservice teachers' digital competencies and innovativeness. 58 students participated in the current study. Using a mixed-methods sequential explanatory design, changes in digital competencies and innovativeness were analyzed before and after the flipped course. Findings revealed statistically significant gains in preservice teachers' digital competencies and innovativeness, and qualitative findings revealed the reasons for these gains. The most common themes were using Web 2.0 tools for teaching, acceptance of flipped learning, doing research, and gaining different perspectives. Based on these findings, it is argued that the use of flipped learning approach removed the time barrier in classes and enabled teachers to gain experience on effective technology usage through actual physical application. The study's results provided recommendations for further research on the connection between flipped learning and the development of preservice teachers' digital competencies and innovativeness.
