A Comparative Investigation of Peer Revision versus Teacher Revision on the Production and Comprehension of Relative Clauses in Iranian EFL Students’ Writing Performance

Abstract

This study compared teacher revision with peer revision on comprehension and production of relative clauses (RCs) in Iranian EFL students' writing performance. Data were collected from 109 Iranian intermediate language learners studying at Imam Khomeini International University and Kharazmi University. After being homogenized by taking Michigan Test of English Language Proficiency (MTELP), they were divided into three groups (teacher revision, peer revision, and control). They all sat for the pretest. Then, the students in teacher revision and peer revision groups underwent eight treatment sessions, practicing teacher revision and peer revision respectively. The control group, however, did not receive any treatment. Then, the posttest was administered to all the groups. ANCOVA was employed to compare the performances of the groups. The results indicated that both teacher and peer revision were beneficial to students. However, peer revision led to better comprehension and production of RCs. The findings may carry implications for language educators, language learners, and language teachers.
