The method of teaching in a flipped classroom involves a more student-centered approach. This makes the students more accountable for their own learning. The traditional method of teaching involved the "sage on the stage" where the instructor lectured. In reality, this method of teaching has not been very effective. Instead, by offering pre-recorded lectures, the students are able to listen to the lectures over and over again. When arriving to class, the in-class activities help the students to apply what they have learned. Thus, this becomes competency-based education.
