Comparison of the teaching clinical biochemistry in face-to-face and the flex-flipped classroom to medical and dental students: a quasi-experimental study from IRAN.

Both face-to-face and FFC methods were effective according to the students, but the level of satisfaction with the face-to-face method was higher. It seems that teacher-student interaction is an important factor in students' preferences. However, the students preferred the flexibility of multimedia. It seems necessary to use the advantages of each method in a model appropriate to the students' conditions and available facilities.
