Oral corrective feedback on written errors

Abstract

The current study investigated the differential effect of two types of oral feedback – graduated oral corrective feedback (GOCF) in accordance with sociocultural theory (SCT) and supplemented direct oral corrective feedback (SDOCF) in accordance with cognitive-interactionist theory (CIT) – on Iranian pre-intermediate EFL learners’ written errors. The study used a pretest-treatment-immediate posttest-delayed posttest design with three groups. Two types of tests were employed to measure the learners’ explicit and implicit knowledge of English articles. The results of the repeated measures mixed-design ANOVAs and post-hoc analyses demonstrated that while both types of feedback significantly improved both types of knowledge in the immediate posttest, a clear advantage was found for the GOCF in the long term. The findings indicate that oral feedback, especially the GOCF within SCT, could be an effective means of addressing learners’ written errors and improving their implicit knowledge.
