Impact of Wiki-based Feedback on Grammatical Accuracy of Iranian EFL Learners’ Writing Skill

چکیده

This study was designed to investigate the effects of providing feedback in the interactive environment of wiki on improving the grammatical accuracy of Iranian EFL learners’ writing skill as well as the attitudes of Iranian EFL learners’ toward receiving feedback via wiki. To do so, 50 intermediate Iranian EFL learners, who were chosen by an OPT (Oxford Placement Test) participated in this study and they were divided into two groups, experimental and control group. Both groups were given identical writing tasks. In control group, though, the first drafts were reviewed traditionally in a pen and a paper fashion, whereas in the experimental group, they were reviewed by peers through wiki to provide feedback on the grammatical accuracy of writings. The second drafts all were reviewed by the instructor. The results revealed that using wikis to provide feedback on students’ writing can have a significantly positive effect on improving their grammatical accuracy in a writing task. Moreover, the experimental group was found to outperform the control group on the post-test indicating that there was a significant difference between the effects of providing feedback in wiki vs. providing traditional feedback on the grammatical accuracy of Iranian male and female EFL Learners. With regards to the students’ attitude toward using wiki, a majority of the learners welcomed the application of wiki for EFL writing.
