Erin Sheehan's posted article http://www.umich.edu/webaccess/best/caption.html is a topic that has been on my mind often ever since I learned about Universal Design. Captioning is very important for students with hearing impairments, language barriers, or who are easily distracted by class noises.
One interesting thing that I did learn about captioning is how it can make your video more searchable and how viewers spend more time on a captioned video. Viewers are also more likely to watch a captioned video in its entirety. I have done a good job in my classes as far as presenting material in multiple ways, but I want to make better efforts towards language barriers. I would like to find some free resources that help me with this plan.
