Is it worth the time and effort to overcome the challenges to flipping the classroom? To answer this question, we recruited university students from five government-funded universities in Hong Kong. They were asked to complete two surveys with the same measurements before and after the flipped lessons. The results from round 1 of students' pre- and post-flip learning outcomes did not show significant differences; however, students' critical thinking ability and interpersonal skills were significantly improved in round 2. The authors' findings suggest that the benefits of the flipped classroom may depend on contextual factors that warrant additional discussion.
