The Efficacy of Comprehensive Corrective Feedback in Improving Grammatical Accuracy of EFL Learners’ Writing
Pariyanto, Bambang Yudi Cahyono

Abstract
This study investigated the effect of comprehensive corrective feedback (CCF) on grammatical accuracy of EFL learners’ writing. Two groups of students, a CCF group (n=13) and a comment on content group (CoC, n=12), participated in a quasi-experiment with a pretest-posttest-delayed posttest design and wrote nine expository essays followed by different feedback treatments. The findings indicated (1) that the CCF group outperformed the CoC group in the accuracy of grammatical features in the immediate posttest, and (2) that there was no significant difference in the two groups’ accuracy in the delayed posttest. These suggest that CCF is more effective in improving the grammatical accuracy of EFL learners’ writing for a short term period than CoC.
