"Flipped Classroom" is not piles of video only. Both students and teachers are unsatisfied with dull, repeated videos. It is a combination of interactive group learning activities inside the classroom and direct computer-based individual instruction outside the classroom. The project “Flip, not Flop” aims to create high-quality, interactive and innovative teaching materials for practical Chinese courses. Videos were filmed to raise students' interests, deal with learning difference, offer tailor-made comments to students' presentation and enhance teaching efficiency. Results of student surveys proved “Flipped Classroom” is helpful to their learning.
