EFFECTIVENESS OF EXPLICIT INSTRUCTION OF COHESIVE DEVICES ON IRANIAN EFL LEARNERS' WRITING DEVELOPMENT
The present study aims to investigate the effect of explicit instruction of cohesion and coherence in Iranian EFL learners' writing development. Cohesion and coherence are both important concepts which cover a large number of discourse features of texts that need to be mastered by language learners. The aim, then, is to determine whether the students' writing ability would be improved when teachers explicitly teach these ideas in their classes. In order to achieve the aims, the described methodology has been used. The sample has been randomly chosen from students of English at university level. The results of the Independent-sample T-tests administered showed that for both males and females, the explicit group outperformed the control group and also the higher the proficiency of learners, the better their writing ability. The implication of the study is that ESL/EFL teachers can implement explicit instruction of cohesion and coherence to better teach their students how to write a coherent piece of discourse.
