The purposes of this study are to describe (1) how is the learning trajectory of students taking Micro Teaching courses in class D for the 2020/2021 academic year so that students can practice the Flipped Learning model, and (2) how the Pedagogical Content Knowledge (PCK) of students who take the Micro Teaching course in practicing the Flipped Learning model in every phase. The subjects of this study were 18 students. The type of a research used in this research is the design research. Data collection methods used in this research were observation and documentation. The research instrument used in this study was an observation sheet that contains PCK components that need to be observed when each student is doing the flipped learning process in every phase. The results of the observation of student practice were as follows: (1) more than 70% of students only use one representation in conveying messages at the pre-phase stage, giving greetings, and asking students how is their condition; (2) there are two video streams made by students, and (3) there are two learning paths made by students in the synchronous phase.
