How does captioning work in a college classroom?
Real-time captions in a live classroom setting can be delivered to a student through different mechanisms. If the student is present in person, they are usually receiving captions on a second screen, such as a tablet or laptop, using a solution known as Communication Access Realtime Translation, or CART.
For on-demand or remote classes that are not live, closed captions are usually provided in a sidecar file alongside the video recording, which can be toggled on or off by the user.
