With the transition to completely synchronous online classes, it seems more important than ever before for language instructors to make use of every minute in class to help students practice communication skills. However, Chinese, as a level 4 foreign language, has many unique or difficult grammar patterns which need to be illustrated in-depth by the instructor. To solve this issue, we partially flipped the classroom, letting students learn the most complicated or different grammar patterns in advance through watching the instructional videos and answering several questions to self-check their understanding. This way we have more time to complete the communication tasks in class efficiently. In this talk, you will be presented with: (i) tips on how to make grammar videos; (ii) question types that were used in self-checking; (iii) the implementation of the grammar videos on Canvas; (iv) some flipped classroom activities we used; and (v) students’ feedback on this project.
