The accessibility committee at the University of South Florida St. Petersburg (USFSP) conducted a report on student usage and attitudes toward captions and interactive transcripts in online courses. The results demonstrate the power of captions and their capacity to improve student performance.

Here are the highlights: 

  • 42% of students use closed captions to improve focus on course material.
  • 38% of students use interactive transcripts to boost information retention.
  • Test scores increased by 3% for students who used closed captions.
  • Test scores increased by 8% for students who used interactive transcripts.

Additionally, 29% of students reported using caption/transcript materials as a study guide. In this way, captions/transcripts can be used by students and instructors alike to efficiently create derivative materials for test prep, course review, and more.

Students simply prefer to use captions

To learn more about how and why students use closed captions and transcripts, 3Play teamed up to perform a study with the Oregon State University eCampus.

This study provides insight on the use of closed captions for on-campus classes across the country. Fifteen colleges and universities participated in this study and received a total of 2,124 students responded to the survey. Demographically, there was a relatively even mixture of freshman, sophomore, junior, senior, and graduate students.

Findings revealed that because captions improve engagement for everyone, students with and without disabilities were using captions for a variety of reasons – the most common being the potential to improve focus. 

The study’s top takeaways include:

  • 71% of students who use captions do not have hearing difficulties. 
  • 75% of students indicated that they use captions as a learning aid.
  • 52% said that captions specifically helped them with comprehension.
  • 20% said that captions keep them more engaged with the material.

A&W Canada, a client in the study, reported a 25% increase in watch time on captioned videos. This kind of growth is no small feat, especially considering the endless supply of video content available on social media.

Discovery Digital Networks reaps the benefits

Discovery Digital Networks (DDN) includes closed captions on a segment of their YouTube videos, and wanted to quantify their return on investment before rolling out captions across their entire video catalog. Using 3Play services, DDN conducted a controlled study on the impact of adding captions to YouTube videos.

Here’s what they found:

  • Views on captioned videos saw an overall increase of 7.32%.
  • View count was most dramatically impacted within the first 14 days of adding captions, where DDN saw a 13.48% increase.

These findings were substantial, and proved to Discovery Digital Networks that captions have the power to improve engagement as well as view count.

Brands use captions to improve video-based KPIs

Verizon and Publicis Media conducted a study on the relationship between videos, sound, and captions. This study highlights user preferences and behavior and supports the theory that captions play a significant role in the video-viewing experience.

Turns out, the majority of consumers prefer to watch video with the sound off – in fact, 92% of mobile users and 83% of desktop users report viewing video this way. This viewing behavior causes rightful concern among brand marketers that their audience is missing out on the content they’ve worked hard to provide. 

That’s where captions come in. When captions are included, viewers can still watch, comprehend, and engage with your video content regardless of whether audio is playing. 

In this way, brands can use captions to deliver the soundless and unobtrusive experience their audience wants while simultaneously supporting their own video-based success metrics and KPIs.


The facts don’t lie – the benefits of captioning go beyond accessibility. Captions improve focus in classroom settings, encourage viewers to stay engaged, and boost overall video performance.
