According to this approach, writing is a generative process. It focuses on the writer and the process or the strategies involved in writing. In this study, the author has attempted to consider the using of meta-discourse markers in process writing oriented-approach classes.

The results of statistical analysis revealed that the explicit instruction of process writing approach in EFL courses is quite successful for improving application of meta-discourse features in learners' writing ability.
