Are clinical demonstration videos better for comprehension with both audio narration and subtitles?
A study on the learning experience of dental students in relation to the use of instructional video on clinical complete denture procedures showed that the double modal input of both audio narration and subtitles in the video may not be the most preferred format and design.
Of the 47 dental students who participated in the study, most (97.9%) considered the function of subtitling and/or audio narration useful for understanding, but some found it difficult to concentrate on both at the same time. Some others found the audio narration better for comprehension of information than simply processing subtitles through silent reading.
With or without the audio narration, the subtitling function was perceived as beneficial as it helped to improve note-making, enhance understanding, and focus attention to key concepts and processes in learning.
The study found that the majority of students had very favourable and positive opinions regarding the use of video-based instruction for learning. The video resource was considered valuable in allowing replay and review functions, allowing better visualization of the demonstrated procedure. It was considered a good recap tool of the clinical demonstration and was considered a better revision aid than textbooks.
