This study investigated the effectiveness of two different scopes of corrective feedback on enhancing the complexity, accuracy, and fluency of L2 written productions among 150 intermediate EFL learners participating in intact online courses. The corrective feedback scope includes highly focused and comprehensive feedback delivered via digital platforms in synchronous and asynchronous formats. Participants were divided into five groups: synchronous highly focused feedback, synchronous comprehensive feedback, asynchronous highly focused feedback, asynchronous comprehensive feedback, and a control group receiving corrective feedback via traditional methods, characterized by the indiscriminate identification and marking of all errors. Results across the feedback groups regarding their impact on complexity, accuracy, and fluency in EFL learners' written productions indicated a significant effect on accuracy, while complexity and fluency showed no significant differences based on feedback scope and delivery modality. The results of this study have several important implications for educators, material developers, and policymakers in the field of language education. For teachers, adopting synchronous feedback strategies could significantly enhance the accuracy and complexity of students' written work.
