The purpose of this study was to explore the role of two multi-step oral-revision processes as feedback providing tools on Iranian EFL learners’ argumentative writing achievement. The participants taking part in this study were 45 Iranian EFL students who were randomly assigned into three groups. The participants of the groups were given three argumentative writing assignments, each assignment demanding three separate drafts. In the control group, the participants revised their essays in response to teacher's written feedback, while the participants of the two experimental groups experienced oral-revision talks with their teacher or a peer. Two sets of quantitative and qualitative data were collected: Argumentative essays written at the beginning and the end of the semester and interviews. The results of the quantitative aspect of the study revealed the significant outperformance of the two experimental groups. Moreover, the data provided through interviews revealed some differences in terms of the effectiveness of feedback between the two experimental groups. The participants of the peer-led group reported more awareness of the rhetorical structures and an ability to revise surface errors. While, the teacher-led group reported more global writing concerns like content, organization of ideas, and discourse. The obtained results point out that the mutual co-construction of participation roles and certain combinations of negotiation and scaffolding let the teacher provide a supportive conversational environment and assistance in accordance with the proficiency of learners of the teacher-led group to promote greater learner participation.

The current study examines the impact of different task types on learning prepositions in form and meaning- focused interaction enhancement- based classes. The participants were 57 second Year University students enrolled in three intact lab classes at Tabriz Islamic Azad University. The first group was provided with form-focused interaction enhancement, the second with the meaning-focused interaction enhancement, and the third was the control group which received no interaction enhancement. During 12 sessions, the participants practiced using prepositions employing oral picture description and written picture description tasks. Having practiced using prepositions during the term using different tasks, the participants were presented with Oral Picture Description (OPD), and Written Picture Description (WPD) tasks in posttest. The results indicated that there are differences among the participants regarding their use of prepositions in performing oral picture description task in form and meaning–focused interaction enhancement- based classes. It also became clear that the group with meaning focused interaction enhancement outperformed the group with form- focused interactionenhancement and the control group. There were also differences among the participants of the three groups regarding their use of prepositions in WPD task in form and meaning -focused interaction enhancement- based classes.
