Description

This pilot study investigates whether input-enhanced subtitles facilitate incidental vocabulary acquisition among Chinese university EFL learners. Participants are divided into two groups: one viewing a video with standard bilingual subtitles and the other with bilingual subtitles enhanced through bolded English keywords. Pre-tests, post-tests, and delayed tests are used to assess vocabulary gains in form recognition, meaning recognition, form recall, and meaning recall. The aim is to examine if simple textual enhancements can increase learners’ attention to target words and improve retention. This study seeks to provide insights into the effectiveness of input enhancement in subtitled media for vocabulary learning.

Summary

This pilot study investigates whether input-enhanced subtitles facilitate incidental vocabulary acquisition among Chinese university EFL learners.
