To date, many scholars have explored the WCF or ME alone and in isolation and none of them investigate the integration of WCF plus ME together. So further research is needed to investigate the integration of WCF and ME as a powerful tool to enhance accuracy in writing. Last but not least most of the studies till now has been done with low proficient learners, but in this study we aim at investigating more proficient learners to see the extent to which the effectiveness of written CF is dependent upon the proficiency level of L2 writers. Another point worth mentioning is that many of the studies have been conducted in an ESL context, but since in Iran we are in an EFL context, we can lead a research examining the integration of WCF and ME in an EFL context which is a domain not previously studied or investigated thoroughly by other researchers.
