Teacher feedback is an important part of teachers’ classroom discourse, and it plays a very important role in classroom teaching. Teachers’ effective feedback can not only bring knowledge to students, but also encourage students’ learning. Teacher feedback is a series of behaviors that evaluate or guide students’ classroom performance. Its purpose is to optimize students’ classroom learning process, so that students can understand the teachers’ meaning and make the classroom teaching continue smoothly. Studies at home and abroad indicate that teacher feedback will affect the amount of students’ speech and students’ participation in the classroom to a certain extent. Therefore, the quality of teacher feedback affects the teachers’ teaching and the students’ learning directly.

This is an action research of English teacher. The participants of the research are 45 junior high school students. Classroom observation, student interviews and teaching logs are the processes to analysis the classroom feedback of English teachers and students’ classroom participation. The main purpose of this research is to improve students’ classroom participation by optimizing teacher feedback, and ultimately achieve the purpose of promoting students’ learning and improving the quality of the English classes. This research includes three rounds of researches. By observing the classes, combining teaching logs and student interviews, we can know more about students’ classroom participation and then continuously adjust teachers’ feedback to achieve the ultimate purpose of the research.

After three rounds of data analysis, we obtained the following conclusions: Teachers should increase the usage of positive feedback. For junior high school students, positive feedback is useful to enhancing students’ learning enthusiasm and increasing students’ interests in classroom participation. And reduce the usage of direct corrective feedback, and use a relatively subtle way to help students correct their mistakes is a good way to make them more emotionally acceptable. Use discourse feedback at the right time. The expansion way of discourse feedback is more popular with students. Most students hope to get extended feedback from the teachers, so that they can learn more and inspire their thinking.
