Differential Effects of Non-linguistic Feedback Types on Complexity, Accuracy and Fluency of EFL Learners’ Speaking Performance in Online Education

This study examined the impacts of providing regulatory focus feedback (RFF) in the forms of prevention and promotion as well as reference of comparison feedback (RCF) in the forms of normative and self-referential on EFL learners’ speaking complexity, accuracy, and fluency (CAF) in online speaking courses. For this purpose, 100 intermediate EFL learners in a language institute were randomly assigned into four experimental groups and one control group (N=20). Language learners were required to respond to two speaking tasks from the IELTS exam before and after receiving 16 sessions of the intervention. The data were subjected to ANCOVA analysis and paired samples comparisons. The results showed that the participants’ speaking performance was better in all four experimental groups compared to the control group. Moreover, the superiority of self-referential feedback in improving the participants’ oral production ability over normative feedback was demonstrated. Prevention-focused feedback was shown to be influential in improving accuracy. Finally, practical implications for how EFL teachers can enhance language learners’ oral production ability are discussed.
