Based on the shortcomings found in previous methods of teaching writing and following recent works in applied linguistics and second language acquisition on form-focused instruction, explicit teaching and learning, and types of feedback, the Innovated Writing Process (IWP) approach was designed. This is one of the findings of an empirical study in the context of Arab learners of English (ALEs) in the Sultanate of Oman. It is also an attempt to apply Sociocultural Theory in classroom settings and to show how input can be well-processed which, in turn, can develop the second language (L2) learners' internalized grammatical system.The method used in this study indicates that metalinguistic feedback-one form of interaction between the instructor and learners -may be one of the most successful feedback types in helping L2 learners acquire second language linguistic items.
