One goal of a cete of badgers—Share online information sources that don’t require a subscription or a library card, though I highly recommend getting a library card. In keeping with the stated interests of this site, I'll tend to write about easy‐to‐use reference resources for general audiences (like public library users and the library staff who serve them). Having said that, today I share a popular education site. I learned of it through the American Indian Library Association discussion list and wondered how I hadn’t heard about it before. Public librarians, accustomed to reference questions about math test prep and understanding mortgages, should be as excited about this resource as school librarians and media specialists are.
Khan Academy www.khanacademy.org (specifically, Sal Khan, “Bill Gates’s favorite teacher”) makes excellent use of videos (via YouTube) to explain math. Do not mistake me for a credible expert on numbers; I haven't thought about quadratic equations in 25 years. In fact, my lack of math practice probably has a lot to do with why I’m impressed with Khan Academy videos; I 'get' them. Each video covers a single concept, and those I've viewed cover the concept clearly and succinctly (in about 10 minutes). Over 2000 videos, subjects ranging from basic arithmetic to calculus, and including money matters--Khan is a Harvard MBA--and statistics. Also covers some science subjects.
