Students in a traditional lecture course are 1.5 times more likely to fail, compared to students in courses with active learning The authors found that 34% of students failed their course under traditional lecturing, compared to 22% of students under active learning. This suggests that, just in the studies that they analyzed, 3,500 more students would have passed their courses if taught with active learning. By conservative estimates, this would have saved the students about 3.5 million dollars in tuition. The authors point out that, were this a medical study, an effect size this large and statistically significant would warrant stopping the study and administering the treatment to everyone in the study.

Interactive pedagogy, for example, turns passive, note-taking students into active, de facto teachers who explain their ideas to each other and contend for their points of view. (“The person who learns the most in any classroom,” Mazur declares, “is the teacher.”) Thousands of research studies on learning indicate that “active learning is really at a premium. It’s the most effective thing,” says Terry Aladjem, executive director of the Bok Center and lecturer on social studies. “That means focusing on what students actually do in the classroom, or in some other learning environment. From cognitive science, we hear that learning is a process of moving information from short-term to long-term memory; assessment research has proven that active learning does that best.”
