This study  investigated the effects of  peer feedback in an advanced translation class for  Chinese English  majors． An intact class of 20 junior English majors from Nanjing University took part in this study． After receiving some training on giving peer feedback ，they went through two translation-feedback-revision cycles． Six  students were randomly  selected for follow-up  in- terviews． Data analysis yields  the  following  results: 1) Peer  feedback  was  effective; 2) The  students  incorporated  most  of  the feedback  into their revision and produced significantly improved translations;  3) The direction of translation did not seem to affect the quality  and incorporation of  peer  feedback; 4) The  students  held  positive  attitudes  towards  the  use  of  peer  feedback  in  the translation class． The  researchers  concluded  that  as  a  form  of  collaborative  learning ，peer  feedback  is  effective  in  translation teaching and learning．
