YouTube tutoring

Thursday Feb 5, 2009 18:25:55 EST

Some students are turning to YouTube for free tutoring in math, science and other complicated subjects. A YouTube tutorial on calculus integrals, for example, has been watched almost 50,000 times in the past year.

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.
