| Based on Nunan’s classification method of teachers’ feedback,the feedback of proficient Chinese teachers is divided into three categories: positive feedback,negative feedback and mixed feedback.The research methods such as classroom observation and corpus transcription are used to carry out specific research,and then the input hypothesis and interactive hypothesis are combined to analyze.The selected study case is a proficient Chinese language teacher with over 20 years of teaching experience.By observing the teacher’s two courses and focusing on her online classroom feedback,the characteristics and shortcomings of the proficient Chinese teacher’s online teaching feedback are identified,and suggestions for reference are proposed.First of all,the teaching process of the proficient Chinese teacher is recorded in real-time to accumulate real feedback corpus.Secondly,through the use of phonetic transcription assistant and manual transcription,the corpus is sorted out.Referring to the classification of feedback by previous researchers,the classification and statistical scale of feedback are designed.Through the analysis of the form,content,students’ response to feedback and feedback time,combined with the input hypothesis,the following conclusions are drawn.First,the proficient Chinese teacher has rich teaching experience and a strong sense of feedback.She gives reasonable feedback on different occasions and uses different types of feedback flexibly.Second,in the form of feedback,there are many single feedbacks from the proficient Chinese teacher,and there are also many combined feedbacks.Third,in terms of feedback content,the proficient Chinese teacher attaches great importance to taking care of students’ emotions in learning Chinese,focusing on encouraging praise and euphemistic correction,and supplementing knowledge when necessary.Fourth,in terms of feedback time,the feedback language of the proficient Chinese teacher is generally timely,but due to the network and teacher’s personal factors,there is an advanced feedback phenomenon.Finally,students have different expressions for different types of feedback.For negative feedback and mixed feedback,the response rate is higher,the performance is more positive,and they can correct their language mistakes in time and output correct answers.Proficient Chinese teachers show strong language application ability in the process of using feedback language,which is enlightening to the language ability training of Chinese teachers.This study puts forward corresponding suggestions from three aspects:novice Chinese teachers,proficient Chinese teachers and the language ability training system in universities. |
