The impact of video dubbing app on chinese college students’ oral language skills across different proficiency levels

Oral language skills (OLSs) are essential for English language learners, but challenges remain in developing OLSs, especially in English-as-a-foreign-language (EFL) contexts where traditional teaching methods struggle to effectively engage students. In order to maneuver effective methods to improve Chinese students’ OLSs, the present study explores the use of an English video dubbing app in language learning tasks and investigates its effectiveness in improving OLSs. A mixed-methods approach was used to provide a robust and comprehensive empirical study, including two groups of learners with different proficiency levels. Results from pre- and post-tests, students’ reflection papers, and interviews indicated that the students’ high level of engagement in the dubbing tasks led to significant improvements in students’ OLSs. Particularly in speaking, significant improvements were observed in pronunciation, intonation, fluency, grammar, and lexical use. The study also examined the relationship between the learners’ English proficiency levels and their learning outcomes. The results showed that dubbing tasks had a more significant impact on improving pronunciation for students with lower proficiency levels, while those with higher proficiency levels showed greater improvements in fluency and grammar and lexical use. Pedagogical implications were discussed based on the findings.
