From playback to performance: Enhancing English speaking through question-answer videos
This study explores the use of question-answer videos outside the classroom to improve speaking skills among English 3 EFL students at the National College of Education in Ho Chi Minh City. The study used a quasi-experimental design with 160 students in the treatment group (2023-2024) and 160 students in a historical control group (2022-2023). The treatment group used video-based practice to support their learning. Data were collected through final speaking test scores, questionnaires, and semi-structured interviews with teachers and students. The findings suggest that students who practised with the videos demonstrated greater improvements in grammar and vocabulary, pronunciation, discourse management, and interactive communication than the control group. Participants also reported increased motivation and confidence. Despite challenges related to fast speech, unfamiliar vocabulary, and cognitive overload, the findings suggest that structured video-based practice can support out-of-class speaking development in EFL contexts when tasks are carefully designed.
