Enhancing college students’ listening performance and self-efficacy using mobile annotated vlogs
Hui-Tzu Hsu
Annotated vlogs delivered via mobile devices significantly improved college EFL learners' listening comprehension and vocabulary retention compared to audio-only or captioned vlogs. The annotated vlog group also reported the greatest increase in self-efficacy. The study highlights the potential of mobile annotated video for language learning.
Original abstract
Previous research has demonstrated that annotated or captioned videos can enhance second language learners’ listening comprehension and vocabulary acquisition. However, the influence of annotated vlogs delivered through mobile platforms on these outcomes remains underexplored. Accordingly, this study investigated the effects of annotated vlogs delivered through mobile devices on English as a foreign language learners’ listening comprehension, vocabulary retention, and self-efficacy. This quasi-experimental study recruited 131 college students at a pre-intermediate level of English proficiency, enrolling 43 in the control group that learned through audio files, 44 in the first experimental group that learned through captioned vlogs, and 44 in the second experimental group that learned through annotated vlogs. The research instruments comprised listening pre- and post-tests, vocabulary pre- and post-tests, initial and post-intervention surveys evaluating self-efficacy, a learning perception survey for the annotated vlog group, and semi-structured interviews with members of the two experimental groups. The results revealed that students learning with annotated vlogs significantly outperformed those in the other two groups in listening comprehension and vocabulary retention. The learners in the annotated vlog group also reported the greatest post-intervention increase in self-efficacy.
