(AP) — A free online course is offering students the chance to learn about giving from Warren Buffett and to help decide how to spend more than $100,000 of his sister’s money.

More than 4,000 people have already signed up from the course that will also feature philanthropic advice from baseball legend Cal Ripken Jr., the founders of Ben & Jerry’s ice cream and several other prominent givers. It starts Monday.

Buffett and his older sister, Doris Buffett, will be featured during the first class. But everyone involved with the course says the fact that students get a chance to give away real money may be more important to the course’s success than the speakers.

Rebecca Riccio, the Northeastern University professor who will teach the course, says the money helps make the lessons stick.
