摘要：The role of feedback on writing involves complex issues and needs to be considered within the total context in which the feedback is given. The reason studies examining feedback effects are so inconsistent may be a function of the fact that these studies consider feedback issue from a single perspective. To deal with this problem, feedback is first defined from different perspectives, then different aspects of feedback are discussed and after that a discussion of the factors that affect the influence of feedback on second language writing follows and finally a model where all the factors interact to influence feedback practices in second langue writing is presented.
