The present study was conducted to further improve the practice of written corrective feedback by integrating the two known feedback types (i.e. direct corrective feedback and metalinguistic explanation). With this aim, a sample of sixty-nine high-intermediate Iranian EFL learners was assigned into different feedback groups. While the first and second groups received direct and metalinguistic explanation feedback, respectively, the third group received an integration of both. Results showed that all three types of feedback improved the learners’ accuracy, though with different degrees of success. However, the results of the delayed post-tests revealed that only the integration of Direct Corrective Feedback (DCF) with Metalinguistic Explanation (ME) had the most sustainable effect on the learners' accurate use of the articles in the long run. It is discussed that the integration of DCF and ME can enhance the corrective effect of the feedback and reduce the defects which have been associated with the practice.
