| Flipped classroom teaching model is the product of modern education informatization,but it has few practical achievements in combining with TCFL grammar teaching,especially online intermediate Chinese grammar teaching in the post-epidemic era.Chinese grammar is quite difficult for international students.Currently,due to various reasons,there is limited time for students to practice grammar points in online classes,and they may not be able to fully internalize grammar knowledge in class time.Therefore,this paper,taking intermediate students as the research object,tries to explore the effect of the combination of flipped mode and online intermediate Chinese grammar teaching,hoping to provide some new ideas for Chinese teachers to design online grammar classroom.Based on the error analysis of bi sentence in Chinese interlanguage corpus and scholars’ research on the selection and ordering of comparative sentence grammatical items,this paper determines that the grammar point of flipped intermediate Chinese teaching is fuzzy comparative sentence.On the basis of literature review,three basic steps of flipped online intermediate grammar teaching are designed as an important basis for subsequent teaching design.According to the analysis of the errors of fuzzy comparative sentences acquired by Chinese learners,the teaching objectives and key and difficult points are determined,and the teaching process of pre-class,in-class and after-class is designed respectively,and the teaching practice is carried out.Before class,the teacher released the micro lesson video of "BI",and the students completed the watching task and self-study test paper on time.During the class,various exercises were designed to lead students to consolidate and internalize the grammar points of "BI" sentences,and class videos were made throughout the class.After class,the teacher collects and corrects the written homework,and summarizes and evaluates it.According to the interview results and students’ feedback,they are quite satisfied with the micro class,think the video is rich and easy to understand,and also like this novel learning way.According to classroom observation and homework,students are active in this online flipped teaching,with high participation in class,enough cooperative learning time,and high accuracy rate of homework completion after class.The above proves that the combination of flipped classroom teaching mode and online intermediate Chinese grammar teaching has certain feasibility,and the teaching effect and students’ response are relatively good.The paper hopes that this study can provide teaching ideas for front-line Chinese teachers to design online grammar courses and try to use flipped classroom to teach grammar in current online teaching."Intensive" before class,"practice more" in class,fully embodies student-centered teaching concept,to better promote the development of grammar teaching Chinese as a foreign language. |
