Effectiveness of Flipped Classroom Models in Undergraduate STEM Gateway Courses
Quick fact
Meta-analyses of flipped classrooms in undergraduate STEM gateway courses show an average improvement of about half a letter grade, yet the effect varies dramatically across different implementations.
Why this is interesting
You've heard that flipping the classroom boosts learning, but does it really work for the toughest STEM courses—and why does it sometimes fail?

Understanding Effectiveness of Flipped Classroom Models in Undergraduate STEM Gateway Courses
A flipped classroom reverses the traditional flow: instead of listening to a lecture in class then doing homework at night, students first watch short video lectures at home, then come to class ready to solve problems. This structure likely works by giving students control over the passive learning phase—they can pause, rewind, and rewatch—so they arrive with foundational knowledge. Then, the valuable classroom time is transformed into an interactive workshop where they apply concepts under an instructor's guidance. This shift from passive to active learning is thought to be the key, because actively solving problems forces deeper processing than simply hearing information.
A deeper explanation
The effectiveness of the flipped model rests on the principle of active learning: the brain learns better when it is forced to retrieve, apply, and evaluate knowledge, rather than merely receive it. In a flipped class, the initial exposure to new material happens through video, which can be delivered efficiently and can free up class time for problem-solving. During class, students work through problems collaboratively or with immediate instructor feedback, turning the lecture time into a supervised practice session. This mechanism is supported by a wide body of evidence—on average, students in flipped classes outperform those in traditional lectures by approximately 0.5 grade points, but only when the in-class activities are truly active and the out-of-class videos are well-designed. When instructors merely replace the lecture with video and keep class as lecture, there is no benefit. Thus, the flipped model is not inherently effective; its success depends on the quality of both components and the alignment of the in-class activities with the learning objectives.
