Math instruction via You Tube

The Kahn Academy is here

From the AP:

Need help with class? YouTube videos await


MIAMI (AP) — When University of Central Florida junior Nicole Nissim got stumped in trigonometry, she checked out what was showing on YouTube.

Nissim typically scours the video-sharing Web site for clips of bands and comedy skits. But this time she wasn't there to procrastinate on her homework. It turned out YouTube was also full of math videos. After watching a couple, the psychology major says, she finally understood trig equations and how to make graphs.

"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."

YouTube is perhaps best known for its cavalcade of homemade performances and TV clips, but many people like Nissim are turning to it for free tutoring in math, science and other complicated subjects.

Wouldn't it be nice if our college students learned trig in high school.

School closures in Seattle ...

The door of Scrooge's counting-house was open that he might keep his eye upon his clerk, who in a dismal little cell beyond, a sort of tank, was copying letters. Scrooge had a very small fire, but the clerk's fire was so very much smaller that it looked like one coal. But he couldn't replenish it, for Scrooge kept the coal-box in his own room; and so surely as the clerk came in with the shovel, the master predicted that it would be necessary for them to part. Wherefore the clerk put on his white comforter, and tried to warm himself at the candle; in which effort, not being a man of a strong imagination, he failed.

"A merry Christmas, uncle! God save you!" cried a cheerful voice. It was the voice of Scrooge's nephew, who came upon him so quickly that this was the first intimation he had of his approach.

Thanks. This is a good find. I'm surprised I haven't come across this before. Not only will I recommend these videos to others, I'll enjoy them myself.

Just a quick look showed them to be very straightforward... no bells and whistles... just the facts, ma'am! If you are looking for a song and dance entertainment approach for your learning, go somewhere else.
