Importance of Captioning in Higher Education
About 20 percent of Americans, approximately 48 million, report some degree of hearing loss. Sixty percent of the people with hearing loss, over 28 million, are either in the workforce or in an educational setting (hearingloss.org). In this instance, captions, used in conjunction with transcripts, provide a text alternative to audio content which is essential to providing equivalent information.
In a nationwide research study conducted by Oregon State University's E-campus Research Unit, 98.6% of students surveyed reported that they found captions helpful. In addition, 75% of all students who use captions use them as a learning aid. The number one reason students gave for using captions was to help them focus on the video content.
As the study indicates, captions benefit everyone, not just deaf and hard-of-hearing individuals. Providing captions and transcripts can:
- Enhance the educational experience for people who respond to different learning styles and preferences.
- Allow content to be utilized by those in either extremely loud or extremely quiet environments.
- Ensure non-native speakers have access to information in videos.
- Facilitate understanding of vocabulary, or information presented in different dialects, as part of captured lectures or other video resources.
There are several automated captioning tools available. While some are quite good, they likely will not get all of the words correct. Faculty and course designers are encouraged to review all captions for accuracy.
In some cases, up to 80% of viewers using captions are not considered deaf or hard of hearing, including instances when a person cannot listen to audio because of their work or study environment. (For more information, see "Video Captions Benefit Everyone").
