Giving written feedback to students is an important part of writing instruction. However, few studies have been conducted to investigate current trends of written corrective feedback in the secondary and university contexts. To identify and evaluate the current state of empirical evidence, we conducted a qualitative synthesis of published research that examined written corrective feedback in both English-as-the-first-language and English-as-the second/foreign-language settings. Four claims emerged in our analyses of 68 empirical studies published in journals from 2006-2016. Each claim is supported by empirical evidence. The claims are: (1) Individual differences play a part in the effectiveness of written corrective feedback; (2) Students’ and teachers’ perceptions affect the effectiveness of written corrective feedback; (3) Giving corrective feedback through technology is beneficial to students; and (4) Written corrective feedback is more effective when it is used concurrently with collaborative tasks. This meta-synthesis study sheds light on the written corrective practice of English Language teachers across different pedagogical settings and the factors that may affect student engagement in teacher written feedback.
