Captioning Benefits for K-12 Learners

Captioning is well-known for its success in providing deaf and hard of hearing individuals with access to video content, but current research is daily uncovering the many benefits captions can and do provide to the population at large.

As we look closer at the field of K-12 education, we find captioning can provide a multitude of benefits. What may possibly be surprising to many, however, is these benefits can impact not only the deaf and hard of hearing but ALL student learners.

Particularly in our current climate of COVID-19, which finds many students participating from home via online learning, the teacher’s use of video, combined with quality captioning, can be significant in addressing the needs of all learners.

Whether the content is provided to K-12 learners is in the classroom setting or via remote methods, a significant number of children on the receiving end are facing daily challenges—deaf or hard of hearing, learning disabilities, limited grasp of the English language, learning a new language, attention deficit, and/or momentary or ongoing distractions.

Below are some of the benefits that pinpoint how captioning is proving to be an integral tool to improve student learning.


Improved Comprehension

  • Struggling readers are provided with additional print exposure, resulting in improved reading skills
  • Foundational reading skills are boosted (phonics, fluency, vocabulary, word recognition)
  • Students whose first language is not English are aided in matching words with sounds
  • Reading comprehension scores are increased in comparison to uncaptioned educational videos
  • Visual identification of key terms and phrases takes place

Greater Accuracy

  • Difficult vocabulary is clarified by providing the written word, which can then be further researched as needed
  • Accurate spelling of content words enhances learning
  • Poor audio or stream quality is overcome with captions in place to convey words that may not otherwise be understandable

Increased Retention

  • The ability to recall facts, summarize main ideas, define words, and draw inferences is increased
  • Better note-taking by students is facilitated through video captions
  • Opportunities afforded to read (captions) while watching a video have been shown to aid in information retention


  • High-energy or easily distracted students have been found to improve focus through the combined efforts of video and reading
  • Students’ attention is better captured, as they are naturally drawn to read text that appears on the screen
  • Reading opportunities are extended, which Improves reading achievement and proficiency through written and verbal engagement

Accessibility in All Environments to All Learners

  • Provides benefits to all students, with or without hearing challenges or learning disabilities
  • Allows learning in the midst of any venues—loud or quiet, at home or in the car, etc.
  • Searchable options (by keywords, concepts, etc.) are provided through closed captioning, thus allowing for greater and easier access to content

With instruction being the primary purpose of videos in K-12 education, captioning is an excellent tool for serving all learners. Accuracy is essential for any type of captioning, but especially so in education. It is crucial that proper grammar and spelling are utilized in the presentation of daily lessons. It is true this can prove challenging, due to numerous factors such as equipment failures, background noise, audio quality, and more. Therefore, it is important to pursue quality captioning in order to accomplish the end goal.
