Close Captions
Must-haves
Ensure that your platform provides access to accurate closed captions as well as full transcripts for learners. Provide access to translated CCs and transcripts, when possible, to include other language learners. Providing written versions of your video content ensures that folks with different learning styles, preferences, language comprehension, internet connections, etc, can access key course information.
Nice-to-haves
Consider building out transcript display options next to your MOOCs. For example, enable a transcript viewing window with automatic scrolling that highlights the words being spoken on screen, so users can read along.
Consider making your close-captions and transcripts downloadable for future reference.
Relevant Scenarios for this functionality

Mieko
Mieko is proficient in English, but not quite fluent yet. She likes to have English closed captions on her videos, and appreciates being able to switch them to Japanese close captions when she isn’t sure of certain language.

Adam
Adam has very unreliable internet connection, so sometimes his videos don’t play back very well. When this is the case, he downloads the lesson transcripts so he can complete his homework by reading about the video content.
