MIAMI - When University of Central Florida junior Nicole Nissim got stumped in trigonometry, she checked out what was showing on YouTube.
"I was able to watch them at my own pace and if I didn't get a concept, I could easily rewind it," Nissim says. "It was a lot clearer once I watched the video."
The videos are appealing for several reasons, says Kim Gregson, an Ithaca College professor of new media. Students come to the videos when they're ready to study and fully awake — not always the case for 8 a.m. calculus classes. And they can watch the videos as many times as they need until they understand.
