While some researchers have questioned the efficacy of corrective feedback (CF), other researchers believe that CF can be effective if implemented through new technology types, including e-portfolio (EP). However, whether EP can be used as a medium of providing CF for language learners at different levels of language proficiency is still unknown. The purpose of the present study, therefore, was...
