Although a growing body of research has examined the effectiveness of written corrective feedback (WCF) for improving L2 learners' grammatical accuracy, fewer studies have investigated the extent to which different educational settings would influence learners' perceptions and preferences of WCF. This paper reports on an exploratory study that investigated learners' perceptions and preferences of WCF in an EFL setting. Quantitative and qualitative data were collected from 64 intermediate, advanced-intermediate, and advanced English learners across three proficiency levels (intermediate, advanced-intermediate, and advanced) in a major provincial university of Mainland China. Through extensive written questionnaires, the study explored these learners' perceptions and preferences of the various dimensions of WCF. The results showed that although the participants tended to have a neutral opinion on the role of explicit grammar instruction, overall they expressed a favourable attitude towards error correction. In particular, they held a strong preference for extended comments on both content and grammar of their written work. The qualitative data further indicated that the participants wanted to take more initiatives in the revision process of their writing with less interference from teachers. Overall, the findings confirm the value of WCF for EFL learners outside English-speaking countries. The findings also highlight the significance of individual and contextual factors in the ongoing debate over the effectiveness of WCF.
