Student-centered pedagogical methods have gained popularity in recent years. Various active learning strategies are being used at schools of all levels. This study describes a flipped classroom with student teaching strategy employed in an international business course and evaluates its effectiveness on student learning. With primary data of 152 students covering two semesters before and two semesters after the implementation of the new strategy from 2016 to 2018, preliminary evidence shows that the flipped classroom with student teaching improves student attendance, performance, and the overall satisfaction of students with the course. By controlling for the other factors that could contribute to the improved student performance, a regression analysis with year fixed effects further confirms the preliminary evidence that flipping the classroom with student teaching improves students' learning and performance, which corroborates the theory of "learning by teaching" by Dr. Jean-Pol Martin. This research benefits the professors who are thinking of incorporating more student-centered active learning activities in their teaching.
