An instructor transformed an undergraduate business statistics course over 10 semesters from a traditional lecture course to a flipped classroom course. The researcher used a linear mixed model to explore the effectiveness of the evolution on student success as measured by exam performance. The results provide guidance to successfully implement a flipped classroom course. The largest improvements were achieved by replacing face-to-face lecture with active learning exercises and using quizzes to verify student engagement with offline materials. Using conditional release of course materials to encourage homework completion also provided a significant benefit to students who missed class often.
