Since the early research in Second Language Acquisition (SLA), studies of Written Corrective Feedback (WCF) sought to answer several questions about CF and especially WCF: reasons to correct errors, which errors to correct, when to correct, how to correct and by whom. However, initial studies did not focus on the question that is vital in this area today, that is, if CF has the potential to contribute to the development of the target language (BITCHENER & FERRIS, 2012). This article reports the results of a pilot study that addresses the effectiveness of WCF. The findings reveal that the experimental groups outperformed the control group in the written posttest; however, due to certain limitations of the pilot study, the results need to be revised with caution.
