in Cairo and categorized into two experimental groups studying a program designed for contextualizing grammar in writing. To assess the findings of that program and fulfill the purposes of the study, a writing test and its analytic scoring rubric was developed. The results of the study consistently demonstrated that both direct and indirect modes of feedback had high effectiveness in developing grammatical accuracy in writing as the participants who received direct or indirect corrective feedback showed better performance in the post-test than that of the pre-test. The study ended with discussing the findings reached, presenting recommendations, and suggesting some issues for further research.
