6. Conclusions
Flipping the class is a popular technique in higher education, and recent studies have documented flipping to improve studentlearning outcomes in the principles of microeconomics classroom. Researchers have yet to uncover the mechanism through which flipping is successful, nor have they identified if the effectiveness of flipping varies by class spacing. A benefit of the flipped class is that it allows students to engage in active learning during class time either individually, in pairs, or in groups. If the classes are not long enough, activities may be interrupted and have to be resumed the following class period, perhaps weakening their effectiveness. Thus, longer class periods may allow for activities to be completed in one class period only. On the other hand, having to resume the activity another day may require students to revisit the material and refresh their memories on the activity, thus reinforcing the material.
Studies have also yet to identify if class size affects the flipping effectiveness. As students may often work in groups during class time, smaller classes may not allow for a large enough quantity of groups to make activities effective, large enough groups, or the ability to change groups, all of which may benefit the student or enhance the activities. On the other hand, being in a smaller class may make the course more intimate, allowing students to feel more comfortable and at ease with one another, encouraging learning, teamwork, communication, and cooperation.
This study utilizes a retrospective dataset of one instructor’s principles of microeconomics classes over the course of five semesters to identify the effect of flipping on student learning outcomes, as well as how the effect may differ depending on class duration and frequency and class size. It further investigates how student evaluations may differ along these same characteristics.
