A case study was carried out to test the effects of self and peer evaluation in the process of English majors' English pro-nunciation teaching and learning. First-year English majors were directed to do self and peer evaluation, whose views on the evalu-ation experience were collected through individual talks and a questionnaire. The significant majority of subjects have found the re-flection helpful in promoting their English pronunciation learning and facilitating autonomy. However, problems rise with changesof teachers' roles in the class and their assessment on students' performance and learning progress.
