A great deal of studies have shown that corrective feedback (CF) has a great significance in SLA. Generally, feedback is provided in response to learners’ errors. Different types of corrective feedback can be given in treating learners’ error. Also, Learners' perception regarding feedback provision is another important factor that must be taken into account while providing CF. In this study, the effects of different types of feedback on learners' written accuracy considering the relevance of learner's perception and three feedback types including oral, written, and oral / written were investigated. The data was collected through writing tasks and the perception questionnaire from among three different groups. This study showed that effects of different feedback types were different from each other based on available data. The result showed that the group that received oral + written feedback outperformed than two other groups. Although the differences between oral and written groups was not significant, their written accuracy improved to some extent. Findings revealed that students’ perception toward feedback was positive. Key Words: written accuracy, learner's perception, oral feedback, written feedback, SLA
