The Effect Of Computer-mediated Communication(CMC) On Enhancing Iranian's EFL Learner's writing Skill.

The purpose of the present research was to investigate the effect of web-based learning model using scaffolding system to enhance Iranian EFL learners’writing skill. To fulfill this purpose, 05 pre intermediate learners of one of the Foreign Language Institutes in Saveh were randomly selected throughrunning a Preliminary English Test (PET). Then, they were randomly divided into one experimental and one control group. The same content was taught to allgroups while the experimental group worked in small groups of five members (scaffolding system), and put their writing samples on the website, and the controlgroup, wrote their writings individually on the paper (traditional method). A pre-test and post-test were given to learners in all groups before and after the instruction and the mean score of the post-tests were compared through an independent sample t-test whichled to the rejection of the two null hypotheses, concluding that web-based learning model and using scaffolding system had a positive effect on improving learners’ writing skill.
