This study compared the effects of teacher-provided written corrective feedback and manipulation of resource-directing dimensions of task cognitive-complexity along +/- Here and Now condition on the grammatical accuracy of Iranian EFL learners’ writing products. There were 45 participants in the study who were randomly assigned to three experimental groups. All the participants were first given a prompt for the pre-test of writing, and then each group received its own intervention (direct written corrective feedback, indirect written corrective feedback, and task manipulation) for four sessions during four weeks. Subsequently, all the groups took the pre-test prompt of writing for their post-test performance after which the data were collected for the statistical analyses and fed into SPSS. The findings of the study confirmed the significant effects of direct written corrective feedback on increasing the grammatical accuracy of learners’ writings. There were implications, then, based on the results, highlighting the role of meaningful context of task application in the classroom.
