Shadowing has widely been utilized in English language teaching classes, especially in interpretation training courses for decades and has become a topic of avid interest to various researchers such as Lambert (1992), Murphey (1995, 2001), Shiota (2012), and Hamada (2014). However, there has been no research conducted on the effect of implementing shadowing on fluency improvement in English interpretation in Vietnam. In response to this gap in the literature, this study aims to investigate (1) the possible connection between shadowing practices and the interpreting performances of the third-year English-majored students in the educational context at Hanoi University of Industry (HaUI) and (2) the students’ perceptions of the application of shadowing in interpreting classes and its impacts on interpreting fluency. 54 third-year students at the Faculty of Foreign Languages (FFL), HaUI took part in a two-month experimental research, divided randomly into two groups including experimental and control groups. | Shadowing and interpreting performances of English-majored students
